Email is an electronic main which allowed messages to be exchanged from computer to computer. It is also used to create, send, receive, forward, store, print and delete the email.
For example, yahoo, Gmail, MSN and Hotmail.

 

Now the second application of internet is the web. It contains hypertext links or highlighted keywords and images that lead to related information.

A web is organized using documents called web pages. A collection of linked web pages that has a common theme or focus is called a website.

A website is a collection of documents. To identify web pages, need the exact location, web browser on Uniform Resource Locator (URL).

URL has four major parts that tells the web browser as fallows,

1.     Transfer protocol

3.     Then you need special software called browser to access the web

I also learnt that the service provider to access the web which is called information system protocol (ISP). It’s a commercial organization that sells temporary connections to subscriber. For examples Maxis, Celcom and Microsoft network.

Web browser is a software program is used to view web pages.

After that, our lecturer also elaborates about the client and server of web.
Web server: are computers that deliver web pages. Every web server has an IP address and possible domain name.

Web client: are end users

The next source that is used to open web pages is Protocol. The transfer protocol is the set of rules/software that computer use to move files from one computer to another on the internet.

Chat Rooms:  are used to typed conservation between people. Chat rooms are mediums and location on the internet that allows people to chat with each other. For example, Yahoo message chat room and Facebook

I also learnt about the VOIP which is the internet service to access the websites. It’s abbreviation of “voice of internet protocol” or “ internet telephony” for example Skype, Yahoo voice and window live call.
