ABSTRACT

Tools links is an application which provides services to both technical and

nontechnical people.

This provides an interface to access almost all kinds of calculators and

converters.

This also provides some basic information about almost every topic of

science and technology.

The main purpose of this application is to provide the tools like calculators

and convertors at a single place.

Tools links is also called as “Tech Helper”.

3

INTRODUCTION

Tools links is a web application which has almost all the

technical information, formulae.

It also provides converters ,calculators and information about

them at a place.

Users should be able to use these conversion tools with ease.

By using this application users can get useful information

before performing their required conversions and

calculations.

4

OBJECTIVE

Earlier, the calculations are to be made manually and

there’s no single platform where one can find all the

required information about any topic of science and

technology.

Various tools were available but not at single place.

Accessing the tools was also a difficult job for non-

technical people.

5

PURPOSE

This web application is very much useful to the students

as well as nontechnical people.

By using this application users can perform conversions

and calculations very easily.

Operations are performed by just entering the value.

It also provide basic information about those tools and

technologies.

6

EXISTING SYSTEM & DISADVANTAGES

Existing system was the manual system.

In this manual system user must perform operations by remembering corresponding

formulae.

This doesn’t provide any information about the tools which is desired by user.

There is a problem for users to perform operations by their own.

DISADVANTAGES:

No reliability.

Problems with remembering formulae.

High error rate.

User should perform whole work.

Difficult to compute.

7

PROPOSED SYSTEM & ADVANTAGES

In proposed system, all the operation which are desired by the user are

performed by the system itself.

The user just need to enter the values on which he/she wants to perform the

calculations.

The system takes the value as input and perform required calculation.

The result is displayed instantly on screen.

ADVANTAGES:

High reliability.

High accuracy.

Less effort.

Less time to compute.

SPECIFICATIONS

SOFTWARE REQUIREMENTS:

Operating system : Windows

Front end : PHP

Back end : Mysql

Browser : Mozilla Firefox or Internet explorer

HARDWARE REQUIREMENTS:

RAM : 512MB

Hard disk : 10GB

Processor : Pentium IV

9

MODULES In proposed system we have two modules:

1. Admin

2.User

ADMIN FUNCTIONALITIES:

Admin controls the whole system.

He maintains all the information about the technologies and conversion

tools.

He can add users to access this application.

He can insert, modify and delete new tools as well as description about

new technologies.

10

User Functionalities

After registering of user he can access the system.

He can perform calculations which he wants.

He can also know about new technologies.

He can compute all operations accurately with in a less

time.

CONCLUSION

Tech helper is a core component built to help the users to

make all kinds of scientific calculations and conversions.

Users can also get some basic information about some

prominent topics of science and technology.

Moreover, this application was developed in such a way

that any further modifications needed can be easily done

like when there’s any technology upgrade.

FUTURE ENHANCEMENTS

In future we are planning to

Provide Software as downloadable file on user’s request.

Add some sample programs wherever required and an

interface to execute the sample programs which helps the

user to have a more clear understanding of it.
