Chapter 1Introduction

1.1 Background of the Study

The development of the computer technology and network communication technology

makes it possible for human society to enter a world of information. But nowadays,

most of the computer laboratory is still in the primitive stage of manual management.

This not only is extremely inconsistent with the development of computer science, but

also wastes much of manpower and material resources, so it has been an emergent

question for computer laboratory management to develop a Computer Laboratory

Management System and use it replacing primary manual management.

Diliman Computer Technology Institute (DCTI) is a private, non-sectarian tertiary

educational institution. Situated along Commonwealth Avenue in Quezon City, DCTI

offers courses such as Bachelor of Science in Business Administration, Bachelor of

Science in Elementary Education, Bachelor of Science in Elementary Education and

Bachelor of Science in Information Technology.

DCTI ensure that the students are well instructed not only by lecture but also in

laboratory activity that is why computer laboratory of school should always be in good

condition.

Maintaining computer laboratory requires man power and attention of the computer

administrator that is why the administrator cannot fully monitor the laboratory which

leads to computer problem such as computer viruses, improper shutdown, unnecessary

browsing of internet which is not relevant for learning, and malfunctioning of computer

peripherals.

The researchers intended to create a computer laboratory management system that will

help the administrator in maintaining the laboratory. The system is designed to do

variety of command such as turning off client computers from server workstation,

monitor the website that the students browse, send and received message from server

to client in order to quickly assist student requests and concerns.

1.2 Statement of the problem

The following statements are the problems in creating an Automated Computer Laboratory Management System for Diliman Computer Technology Institute

What data structure must be incorporated in the program to prevent laboratory computer from malfunction due to virus infection?

How can the administrator trace student activities in the computer laboratory?

Is the system acceptable in terms of Functionality, Reliability, Efficiency, Usability, Maintainability and Portability?

What statistical method must be incorporate in order to get accurate result of the respondents?



1.3 Significance of the Study

The Researchers intended to create a Automated Computer Laboratory Management

System for Diliman Computer Technology Institute to help the school in maintaining the

computer laboratory. The Student will be the top beneficial of this monitoring system.

They have the right to comment, suggest, and report any changes or problems they

would similar to acquire. This system will manage the student desire for them to

continuously focus in their work without encountering any problem and as the result of

this research the student can work in the computer laboratory more efficiently,

professors can teach more effectively, and administrator can quickly monitor the usage

of computers in the laboratory and determine a problem right away if there is a

tendency of failures in the network. In Addition, the importance of this system is

increment need to such system in organizations, Computer Laboratory Monitoring

System is important to manage and monitor the hardware parts of the computer in

laboratory. Developing this system will provide improved and accuracy in monitoring,

and reducing the time and efforts and future researchers will benefit who wish to have

similar studies as they can get background information from the result of this study

which will serve as a prototype to modify their research and for other improvements.



1.4 Scope and Limitations

The researchers used Visual Basic 2008 for creating the system and Microsoft Access for

handling the database. The system has two parts; the Administrator and client, the

Administrator can monitor the usage of computer in the computer laboratory. The

administrator can access all command in manipulating the computers in the lab e.g

shutdown, lock, restart, send message, and viewing of message of the client. The

administrator can also verify how long does a client is using the system unit, he can also

check what is the schedule of the students registered in his database in the event that

the student login not during his schedule the student cannot access his account to login,

the admin can also restrict websites that is unnecessary, the student can send message

to the administrator if ever they have request and concerns in the laboratory, in the

event that the student failed to give the correct username or password five times the

system unit will automatically shutdown to ensure that the student is using their

account the student can change their password from time to time to avoid possible

hacking or leakage of password and in the event that a student forget its password the

student should ask the administrator to reset his password.

In this study, the researchers limit the system within a specific workgroup. The client can

only access computer by giving their student number and password. Sending of message

is limited only within the specified workgroup. The administrator would not be able to

determine if the system unit is properly or in properly shutdown by the client. The



Monitoring System cannot give the specific status of every computer if there is a vacant

unused computer in laboratory.

Literature Review

2.1 Review of Related Literature

Computer Lab Management Software

Whether the students using the computer are young or old, access to these lab

management features is extremely helpful. As many staff development presenters

know, it can be even more difficult to teach technology skills to adults (in particular

teachers) than to young people. When an instructor wants to limit off task behavior

(similar surfing websites unrelated to the presented lesson), encourage time on task, or

present oral instructions to students, these software tools are wonderful additions to a

technology-infused learning environment. Some management programs offer additional

features with wonderful instructional benefits for classroom teachers and students.

Transfer a file to all student computers: If a school file server is available and a "shared

folder" has been created allowing student as well as teacher access, files for a particular

lesson can be opened from the network. Some lab management programs allow for the

distribution of files directly to the hard drive of every computer in the lab, however, and

some can even retrieve modified and saved files from the student computers to the

instructor computer at the end of class.

Chat: While some teachers may think this feature is superfluous and unneeded, chat

capability included with lab management software can be invaluable for a variety of



reasons. First, most students love to chat on their computers: typing text messages to

each other similar they would in an online chat room. A major difference between an

online chatroom and a chat environment provided by a lab management software

program is that the participants are controlled: only those students physically in the

room can participate in the chat. As a reward for staying on task or completing a lesson,

students can be given five minutes of chat time at the end of the period. Students

desperately need guidance and instruction on what is appropriate and safe to disclose in

an online chat environment, so in addition to motivating students, chat sessions can also

provide them with invaluable digital safety skills. [3]

Computer Laboratory Management Software System.

"Computer lab management software" refers to programs used by Administrator in the

school to maintain the student attention. Screen sharing is a typical feature of lab

management software, allowing the teacher's computer screen or another student's

screen to be shared with every other computer in the lab. Effective use of computer lab

management software can make a tremendous, positive difference when teachers use a

computer lab for instruction.

Software Features



Using lab management software to present a technology-infused lesson can completely

change the way a teacher presents content and teaches skills. Instead of straining their

eyes to see small details on the screen at the front of the room, students can look at

their own monitor in front of them and comfortably see the teacher's demonstration.

When it is time to get everyone's attention, the teacher can "blank" student screens

(make them all black), thereby preventing them from continuing their work. While some

lab management software programs offer more advanced features, the following are

the basic features that all should include

1. ScreenSharing:

Making all computer screens in the room show the same image, usually the

instructor's screen. Many management programs allow sharing of other screens

as well, so if a student has created something the instructor wants to show

everyone, this can be accomplished quickly. When screen sharing is disabled, all

student computers return to their previous screens.

2. Blank Student Screens:

This is invaluable for getting student attention and providing class instructions. The

blank screens command causes all computers in the room except the instructor's to

turn black (or another color) and sometimes display a message. Some programs

offer the option of displaying a custom image. While screens are blanked, students

cannot see anything on their own screen or continue to work.

3. Remote Control:



Depending on the instructional setting, this feature may have more "gee whiz" value

than practical use, but many programs allow instructors to take remote control of a

student's computer to demonstrate a task. This feature may be more helpful to

technical support staff who need to make configuration changes or even

installations on remote computers than to classroom teachers.

4. Unique Room Codes:

Lab management programs, when initially setup on "client" (student) and instructor

computers, permit a unique name or number to be assigned for the classroom

where the computers are located. This way, instructors can choose to control only

the computers physically located in the same classroom. Multiple computer labs or

classrooms in the same building can use the same lab management software for

computer control with different room codes and not interfere with each other.

Access to these lab management features is extremely helpful, whether the

students using the computer are young or old. In fact, as many staff development

presenters know, it can be even more difficult to teach technology skills to adults

than to young people. When an instructor wants to limit off task behavior (similar

surfing websites unrelated to the presented lesson), encourage time on task, or

present oral instructions to students, these software tools are wonderful additions

to a technology-infused learning environment. Windows XP Professional and some

other Windows-based operating systems include an optional feature, Remote

Desktop Services, which allows for remote control of desktop computers. These

remote control features can have instructional applications, but do not permit the

same class-wide screen sharing and other capabilities of the lab management

software options discussed in this article.

Advanced Features



Some management programs offer additional features with wonderful instructional benefits

for classroom teachers and students.

1. Shut down or restart computers:

It can be time consuming at the end of the day to shut down all the computers in a

lab or classroom, or to restart them before the next class. Some programs offer the

ability to shut down or restart an entire lab simultaneously with a few mouse clicks

on the instructor computer. Installed Network Interface Cards (NICs) in each

computer must support this feature for it to work.

2. Transfer a file to all student computers:

If a school file server is available and a "shared folder" has been created allowing

student as well as teacher access, files for a particular lesson can be opened from

the network. Some lab management programs allow for the distribution of files

directly to the hard drive of every computer in the lab, however, and some can even

retrieve modified and saved files from the student computers to the instructor

computer at the end of class.

3. Chat:

While some teachers may think this feature is superfluous and unneeded, chat

capability included with lab management software can be invaluable for a variety of

reasons. First, most students love to chat on their computers: typing text messages

to each other as they would in an online chat room. A major difference between an

online chatroom and a chat environment provided by a lab management software

program is that the participants are controlled: only those students physically in the



room can participate in the chat. As a reward for staying on task or completing a

lesson, students can be given five minutes of chat time at the end of the period.

Students desperately need guidance and instruction on what is appropriate and safe

to disclose in an online chat environment, so in addition to motivating students, chat

sessions can also provide them with invaluable digital safety skills. [2]

System Utilities LAN Administration System

System Utilities LAN Administration System - the software for remote administration of

local area networks. It is designed for network administrators working with groups of

systems. This product allows you to copy files and folders, delete files and folders, run

executable files, install software silently, create, delete and change user accounts,

change display settings, create and delete shared network folders, shutdown and reset

computers in your network. The system consists of administration module and client

software. It is recommended to install administration module only on system

administratorls computer. Note: the client software must be installed on all

workstations! There is no additional user rights required to execute administration

module. Administrator rights are required only for product installation. Since client

software installed as a Windows NT service, there is no need to be logged as an

administrator when working with administration module. Other advantage is that there is



no need to log on every computer, as system services executed in the security context

of the Local System account. [4]

Real VNC

VNC stands for Virtual Network Computing. It is a remote control software which allows

you to view and interact with one computer (the "server") using a simple program (the

"viewer") on another computer anywhere on the Internet. The two computers do not

even have to be the same type, so for example you can use VNC to view an office Linux

machine on your Windows PC at home. VNC is freely and publicly available and is in

widespread active use by millions throughout industry, academia and privately [9].

Computer Laboratory Monitoring

According to Ramos, Pallingayan and Padilla the development of technology has

changed the way we live. Computer became famous and considered as the part of the

society today; they are everywhere. And the advancement in discoveries, both in

hardware and software keep coming, day in and day out. It changes and improves at a

rapid speed, companies and institutions have deal with it. This is because the latest

knowledge of development in computer technology grows people’s standard.

In our life today, computer is one of the many inventions that greatly affected our way

of living. In fact, it is regarded as an essential tool in many areas including business,

industry, government, sciences, education, school, home, and in almost any

organization and establishment that exists. It can perform operation and process data

rapidly, accurately and reliably and by using these machines, spending a lot of time and

effort in doing certain task is minimized.



Nowadays, industry is experiencing many technological advancement and changes in

methods of learning. With the rise of globalization, it is becoming essential to find an

easier and more effective system to help an organization or company. In spite of this

matter, there are still business establishments and schools that use the old-fashioned

way.

Computer as part of the innovation in technology manifests bigger changes in world,

economies, banks and other manufacturing centers flourished due to the catching

power of computers in the field of education, not all school can afford to have number

of computer that caused some problem in maintaining the hardware parts.

In a certain way, one thing that is still in manual process is the monitoring of each of the

computer in the computer laboratory. This is one of the problems of the MIS. Dealing

with this matter, the proponents thought of an easiest way to monitor the hardware

parts of the computer in laboratory.

In the Manual monitoring, the student must be signing in the Lab monitoring paper

where the students write their comments whether the computer is working or not

working. The OJT students’ and the MIS members is the one who can monitor and repair

the Laboratory Computers.

Therefore, the researchers realized that some of the manual processes should be

computerized, in form of monitoring system .The present system is focusing in

managing the computer laboratories by defining allocation to different users,

monitoring usage of lab resources and the hardware parts of the computer. The system

also provides efficient reports. [8]



2.2 Review of Related Studies

Improving DCTI network security using ESX Virtual server running on a windows server

2003

According to Marvyn R. Nacion improving the DCTI network with the use of ESX Virtual

Server running on Microsoft Windows Server 2003 as its operating system installed with

Active Directory and Distribution File System (DFS). The Distribution File System (DFS) of

Microsoft Windows Server 2003 is an additional feature of the said operating system that

will serves as the centralized storage device of the DCTI network in conjunction with

Microsoft Active Directory where policies can be used and linked to the users created on

Active Directory. If the ESX Virtual Server successfully installed all the files and current

system state of computers will be backed up and secured. [6]

Login Logout System for Part Time Faculty Member of Diliman Computer Technology

Institute

According to Raymond D. Jambalos developing a Login Logout system which can assist

faculty to organize their daily work hour or the attendance easily and simply. The system

allows users to restore information such as full name, address, contacts, and so on. The

system also allows users to tract or to check own attendance easily and simply. A

properly designed user interface can standardize the input and output mechanism. [5]



Increasing the efficiency of the existing library database system in Diliman Computer

Technology Institute

According to Friscila Ann B. Dela Cruz Library Database System is a basic necessity in a

college library to decrease the queue time in searching for books manually. DCTI does

not have its own LDS and current LDS being used is not accessible by the students. This

study shows an attempt to increase the efficiency of the current LDS by: (a) allowing

students to use the program with limited options (b) decreasing the response time of

the search function (c) improving the GUI (d) adding more helpful features in this thesis,

the researcher analyzes what is lacking and deficient in the current LDS of DCTI and

creates a program that has an increased efficiency through the use of Visual Basic and

SQL with the present technologies, it is expected that the output program will be faster,

have a better graphic user interface and increase in the number of features. [1]

Log-in, Monitoring and SMS Notification in a LAN Based Communication for Elcott Cyber

out source Computer Services

According to Martin and Porcadilla Log-in, Monitoring and SMS Notification in a

LAN Based Communication for Elcott Cyberoutsource Computer Services is a

company owned by Mr. Ernesto C. Boydon. In order to help the company to

increase the popularity of the company, the researchers of this thesis is created

and developed a system that would help the company in checking the



attendances of the trainees and if they are doing their task properly. The

researchers used VB.Net in the development of the system. The system

evaluated based on the following criteria a. Accuracy of Information b.

Completeness of Information c. Ease of Use. d. Timeliness of Information e.

Portability f. Reliability. The results of the surveyed is 4.5 which is the equivalent

is very acceptable. It is suggested that the future developer of the software that

can send a message to the user in the same network or via internet while the

remote live streaming the researcher suggest that either implement since live

streaming is use only to monitor the task to check if the trainees are working or

not or improve the system. [7]

Chapter 3Methodology

3.1 Research Design

The proponents shall adopt a descriptive study, and used grounded theory

approach which observed particular number of students, this will give way to use

qualitative approach similar sampling technique which will give measurable

results and conduct interview to get the students opinions and thoughts

regarding the proposed system.

3.2 Software and Hardware Requirements

The work group, log in/log out, monitoring of activity of the students are windows base

operating system, Windows XP Service Pack one or a much higher version of windows.

For the hardware the central processing unit must be at least Pentium four and two

gigahertz or a much higher. For the memory of computer it should be at least one

gigabyte and the hard disk is at least eighty gigabyte.



3.3 Research Method

The proponents used System Development Life Cycle (SDLC) in developing the system.

SDLC is a conceptual model used in project management that describes the stages

involved in an information system development project, from an initial feasibility study

through maintenance of the completed application.

The proponents used a survey form in order to evaluate the system in terms of

Functionality, Reliability, Usability, Efficiency, Maintainability and Portability. The

survey is randomly selected per year level of the student of Diliman Computer

Technology Institute in order to verify the output per course and year.

System Planning

The Proponents observe and evaluate the current procedure of the computer

laboratory in order to analyze what are the process to be improve and if the

computer laboratory can provide all the necessary service that a student

needed.

The observation and evaluation was done by interviewing some students who

usually uses the computer laboratory and consulting the professors who uses the

computer laboratory for their subject



In developing the Computer Laboratory Management System, the proponents

research on the current process of the computer laboratory the proponents

observed that most of the students who uses to computer laboratory forgot to

shutdown their work station after using in addition students concerns and

request cannot accommodate right away because they cannot ask assistance

directly to the administrator or I.T staff.

System Design

The developers used Visual Basic 2008 an object-oriented computer

programming language for designing the system and Microsoft Office Access a

relational Microsoft Jet Database Engine with a graphical user interface and

software-development tools which is compatible to windows base platform.

System Implementation

System implementation covers a dynamic variety of activities from a detailed

workflow analysis to the actual operation of the computer laboratory of the

proposed system. During system implementation, the student will test the

system to log-in, after logging in the administrator will monitor the activity of the

student in terms of usage of the computers.

The system will also verify the website that a student browsing, if the system can

block website which is not necessary for learning, and if the system can



shutdown, lock, and restart workstations in the laboratory.

System Support and Security

The proponents shall maintain the functionality of the software and security

issues in storing all the information of the propose system. Once the new system

is implemented, the student must evaluate it. Maintenance must be kept up

from time to time. Administrator of the system should also be kept up to date

concerning the latest modifications and procedures made by the programmer.

Operational and testing procedure

The following are the things to consider before installing the system

The software should meet the system requirement of the software.

Workstation that can be used by the user.

Router or Switch used to connect computer.

After ensuring the requirements, the client is ready to install and evaluate the

system. During testing of the system log in screen will appear and the student

should enter their user name. The server needs to create an account. The

administrator can add, update, delete and search an account of the clients.

Evaluation Criteria

The evaluation instrument used for the testing the system's acceptability was



adopted from the ISO 9126-1. The ISO 9126 software quality model identifies six

main quality characteristics namely Functionality, Reliability, Usability, Efficiency,

Maintainability, Portability. The questionnaire was a five point's scale where 5 is

the highest rating with the qualitative description of the "Excellent" and 1 is the

lowest rating with a qualitative description of "Poor". Comments and suggestion

were included in order to find more improvement for the proposed system.

Table 1 show the mean average rating for the project while Table 2 show ranges

of the mean rating and their corresponding qualitative interpretation. The Mean

average rating for the project.

Evaluation Procedure

The system was evaluated by 30 respondents who were composed of student from

different courses and year level and they were randomly selected The system will

undergo several survey for the year in order to determine to result of the new

system.

During the evaluation process, the following steps were undertaken:

The purpose of the survey will explain

The system will demonstrate to the respondents the computer laboratory management system in terms of Functionality, Reliability and Efficiency the proponents shall adopt Fishers exact test if there is significant improvement in the system.



Fisher's exact test is a statistical test used to determine if there are non-random

associations between two categorical variables.

Let there exist two such variables and , with and observed states, respectively. Now

form an matrix in which the entries represent the number of observations in

which , . Calculate the row and column sums and , respectively, and the total

sum of the matrix. Then calculate the conditional probability of getting the actual matrix

given the particular row and column sums, given by which is a multivariate generalization of

the hyper geometric probability function

(Equation 1)

Now find all possible matrices of non-negative integers consistent with the row and column

sums and . For each one, calculate the associated conditional probability using (2),

where the sum of these probabilities must be 1.

(Equation 2)

To compute the P-value of the test, the tables must then be ordered by

some criterion that measures dependence, and those tables that represent equal or greater

deviation from independence than the observed table are the ones whose probabilities are

added together. There are a variety of criteria that can be used to measure dependence. In

the case, which is the one Fisher looked at when he developed the exact test, either

the Pearson chi-square or the difference in proportions (which are equivalent) is typically

used. Other measures of association, such as the similar lihood-ratio-test, -squared, or any

of the other measures typically used for association in contingency tables, can also be used.



The test is most commonly applied to matrices, and is computationally unwieldy for

large or . For tables larger than , the difference in proportion can no longer be used,

but the other measures mentioned above remain applicable (and in practice, the Pearson

statistic is most often used to order the tables). In the case of the matrix, the P-value of

the test can be simply computed by the sum of all -values which are .

For an example application of the test, let be a journal, say either Mathematics

Magazine or Science, and let be the number of articles on the topics of mathematics and

biology appearing in a given issue of one of these journals. If Mathematics Magazine has

five articles on math and one on biology, and Science has none on math and four on biology,

then the relevant matrix would be

McNemar’s test will also be applied in order to analyze the computers which is

working and non working before and after the implementation of the system

McNemar's test assess the significance of the difference between two correlated

proportions, such as might be found in the case where the two proportions are

based on the same sample of subjects or on matched-pair samples.

Although the McNemar test bears a superficial resemblance to a test of categorical

association, as might be performed by a 2x2 chi-square test or a 2x2 Fisher exact

probability test, it is doing something quite different. The test of association

examines the relationship that exists among the cells of the table, as marked in the

adjacent General Structure by a, b, c, and d. The McNemar test examines the

difference between the proportions that derive from the marginal sums of the table:

pA=(a+b)/N and pB=(a+c)/N. The question in the McNemar test is: do these two



proportions, pA and pB, significantly differ? And the answer it receives must take

into account the fact that the two proportions are not independent. The correlation

of pA and pB is occasioned by the fact that both include the quantity a in the upper

left cell of the table.

The core insight of McNemar's test is two-fold: first, that the difference between pA

and pB reduces, both algebraically and conceptually, to the difference between b

and c in the blue-tinted diagonal cells of the table; and second, that b and c belong

to a binomial distribution defined by n=b+c; p=0.5; and q=0.5



In order to test if the treatment is helpful, we use only the number discordant pairs

of twins, b and c, since the other pairs of twins tell us nothing about whether the

treatment is helpful or not. McNemar's test is

(Equation 4)

which for large samples is distributed similar a chi-squared distribution with 1

degree of freedom. A closer approximation to the chi-squared distributin uses a

continuity correction

(Equation 5)

In R this test is given by the function Mc Nemar test. Case control data may be

analyzed this way as well. Suppose you have a set of people with some rare disease

(e.g., a certain type of cancer); these are called the cases. For this design you match

each case with a contol who is as similar as feasible on all important covariates

except the exposure of interest. Here is a table:

4.1 Graphical User Interface

The following figures are shown below when the administrator and user run and navigate the system.

Figure 2. Log-in form of administrator and student



In this figure the user should select one of the circle button whether admin or student

so that the system will recognize what database should be use in order to access the

main menu for administrator or enable the workstation for student.

The username of the student is the student number while the password contains at

least 8 characters long the password may change from time to time by the student so

that the student can secure their account.

The student can only access their account during their laboratory this is to prevent student who uses the computer laboratory not during their class and laboratory

In the event that the student successfully log-in automatic text message will be sent to

the student confirming that the student access the computer laboratory, this will serve

as a record for the student and administrator if ever there are cases of negligence or

missing computer peripherals.

number, IP address, computer name, Date and Time the administrator can search using

student number to filter the record.

The record in the active session can be automatically obtain to client remote control

form and execute command by clicking the record in the active session form.



Figure 9. Client Remote Control

This figure shows all the command the administrator may execute to the workstation of

student. The administrator should select one at a time the administrator can lock,

restart, shutdown, and check running application, stream live the clients workstation.

The administrator can also send message to the student and even block website that the

student are browsing.

The administrator can shutdown all computers that is on because usually student forget

to shutdown their workstation and sometimes student just turn off the automatic

voltage regulator to turn off the computer which is wrong.

Live Stream of administrator to client workstation. This feature is added in order to

monitor the activity of the users in computer laboratory this feature will also serve as



evidence if ever a student is browsing malicious website or playing computer games so

that student who will be caught can be reprimanded by the guidance office.

Remote shutdown is develop so that computers can be shutdown properly to avoid

damage in the hardware peripherals of the system unit

This command requires the IP address and computer name of the workstation that will

be provided by the student who will use the workstation.

Figure 10. Add Course



Figure 11. Add Subject

Figure 10 and 11 shows the form where the administrator may add another

course if ever the school offers another courses while adding of subject is part of

the system because there are cases that the curriculum change as per CHED

4.2 Workstation Diagram

The figure below is workstation diagram using computer, Switch hub and Router

In this diagram it will show how the workstation router and switch are

interconnected to one another.



Figure 12. Computer Connection Diagram

The Device in the middle of the diagram represent the switch hub where the

computers are connected the label signifies the Workstation name and the IP

address.

4.3 Transcription Summary

The proponents interview some Information Technology professor in Diliman

Computer Technology Institute regarding for the feature of the system a Ms.

Joan Saño coined that adding of student should not be complicated the system

should have a feature where it can import and export the database of students



from the database of the registrar’s office.

Mr. Glen Mercines said there should be a feature where aside from the database that

will save login of the students it should be also send via email of the I.T staff in order for

the I.T staff to monitor the login of the student even if his not around.

Analliza B. Ramos said that the system should determine specifically the website visited

of the student and all application that the students open to fully monitor the activity of

students in computer laboratory.

Jocelyn Fajardo said that the proponents should limit the system where it cannot save

logout of the student if there are cases of improper shutdown, power interruption,

negligence to logout.

4.4 Result of the Study
