UNDER-STAND

THE EVOLUTIONof network computing

NETWORK COMPUTING

• Vast web of electronic networks → also known as the information superhighway or the Internet

• Links computing resources of various industries (e.g. businesses, government, education)

• How do they link? → TCP/IP (Transmission Control Protocol and the Internet Protocol)

• Also known as the World Wide Web (the Web) is the most widely used application on the Internet

Don’t Forget…

• There are also 2 major network infrastructures: Intranets

Designed to serve internal information needs of a company E.g. browsing and searching of internal information

(records) and to support communication / collaboration

Extranets Infrastructure that allows secure communications

(connects intranets of different organizations) among business partners

Seen in B2B transactions

“A network is designed to serve the informational needs of a company, using Internet concepts and tools”

Toolbars

• Some Search Engines offer toolbars for additional functionalities

Google Toolbar Yahoo! Toolbar

DISCOVERY


Information inForeign Languages

• The Internet contains information with various languages

• Automatic translation tools are provided by many

• Removes language barrier for easier discovery

DISCOVERY


Information &Corporate Portals

• What is a portal? Personalized gateway to information and

knowledge in network computing Avoids information overload by providing one screen

from which we do all our work on the Web This eliminates retrieval time spent on

integrating disparate IT systems

DISCOVERY



• 7 Types of portals:1. Commercial / Public Portals

Offer content for diverse communities and interests Also the most popular portals on the Internet

E.g. Yahoo! / MSN

2. Publishing Portals Specific community and interests

E.g. Techweb.com / Mashable.com / ZDNet.com

3. Personal Portals Filtered information for individuals

Yahoo! Home Page / iGoogle

DISCOVERY



4. Affinity Portals Support communities such as hobby groups or a

political party E.g. Photokaki.com / Honda Civic Club

5. Mobile Portals Portals accessible from mobile devices

6. Voice Portals Web portals with audio interfaces (speech recognition) Retrieve email, news, etc by voice using a cell phone

AOLbyPhone

DISCOVERY



7. Corporate Portals: Provide single-point access to specific enterprise information and

applications available on the Internet, intranets, and extranets to employees, business partners, and customers

Also known as enterprise portals or enterprise information portals 4 Examples:

Suppliers Portals –Manage their own inventories Customers Portals – Can view products, place orders and track Employees Portals – Training, dissemination of info, discussions Supervisors’ / Workforce Portals – Enable managers and

supervisors to control the entire workforce management process, from budgeting to scheduling workforce.

Getting to understand…

• Supports organizations and transactions of businesses

• Can involve one or several media: text, voice, graphics, animation and more

• Different media can increase the effectiveness of a message, expedites learning and enhances problem solving

• E.g. E-Mail, Chat Rooms, Blogs, Social Networks, etc

#2COMMUN-ICATION“The exchange and sharing of information by sending / receiving messages, documents and files between users”

Getting to understand…

• Types of Collaboration:1. Virtual Collaboration

(E-Collaboration)• Use of digital

technologies to enable organizations or individuals to collaborateo Corporate Portals (e.g.

intranet – APIIT Admin & Payment)

o Google Docs, Skype, Zoho, Dabbleboard, RememberTheMilk

2. Collaborative Commerce (C-Commerce)

• Among business partners / allianceso Supply chains, Dealer /

Partner Networks, Product Networks

#3COLLABO-RATION“Mutual efforts of two or more individuals or groups to perform activities in order to accomplish certain tasks - improving productivity and competitiveness”

PROBLEMS IN COLLABORATION

• What are they? Privacy Security Technical issues (integration / standards /

technology) Different procedures Lack of trust If global, Language Barriers & Culture Shock

MAIN CATEGORIES OF

COLLABORATION TOOLS

Workfl ows & Groupware2

COLLABORATION TOOLS

• What are Workflow Technologies? Movement of information through the sequence of steps

that make up an organization’s work procedures or business processes

Workflow Management The automation of workflows from start to finish, including

all exception conditions Workflow Systems

Business process automation tools (software programs) that automate almost any information-processing task

WORKFLOWS

COLLABORATION TOOLS

• Workflow Applications Collaborative Workflow

Project oriented and collaborative types of processes e.g. sharing / centralized updates

Project Management Systems e.g. Lotus Production Workflow

Addresses mission-critical, transaction-oriented, high volume processes

E.g. Database access, data entry, data storage & retrieval Administrative Workflow

Is cross between collaborative and production workflows e.g. admin systems (APIIT)

Reduce clerical costs

WORKFLOWS

COLLABORATION TOOLS

• What are Groupwares? Software products that support groups of people who

share a common task or goal and who collaborate on its accomplishment.

Groupware implies the use of networks to connect people, even if the people are in the same room

• Groupware Tools / Applications Electronic Meeting Systems

Improve face-to-face meetings

GROUPWARE

COLLABORATION TOOLS

Electronic Teleconferencing Allows two or more people at different locations to have a

simultaneous conference Video Teleconferencing - participants in one location can

see participants at other locations. Data (data conferencing) can also be sent along with

voice and video making it possible to work on documents together.

Web Conferencing - Video Conferencing solely conducted on the Internet

GROUPWARE

COLLABORATION TOOLS

Real-Time Collaboration Help companies bridge time and space to make decisions and to

collaborate on projects Synchronous communication of graphical and text-based

information. Examples:

Interactive Whiteboards - work like the “physical world” whiteboards with markers and erasers, except instead of one person standing in front of a meeting room drawing on the whiteboard, all participants can join in (Dabbleboard)

Screen Sharing Software - allows group members to work on the same document, which is shown on the PC screen of each participant.

Instant Video - is a kind of real time chat room that allows you to see the person you are communicating with (Skype)

GROUPWARE

WEB BASED APPLICATIONS

• Distance Learning (DL) For situations where teachers and students do not

meet face-to-face E-Learning is just one of the methods

Add value to traditional learning modes. It does not replace the classroom setting, but enhances it, taking advantage of new content and delivery technologies

Blackboard Inc – provides and e-education infrastructure (e.g. Learnfinity)

WEB BASED APPLICATIONS

• Telecommuting / Teleworking An arrangement whereby employees can work at home, at

the customer’s premises, in special work places, or while traveling, usually using a computer linked to their place of employment (e.g. remote desktops / connections)

Benefits: Improved productivity Reduced costs (e.g. traveling)

Disadvantages: To the employees – isolation, no workplace visibility, limited

socialization To the employers – difficult to supervise, data security, high cost of

integration
