Basics of Internet, Intranet, Email, Audio and Video-Conferencing UGC NET
1. Intranet:
It is a collection of resources which only internal users can access. It is similar to the internet but it is used for internal purposes only and it is a private network inside an organisation. It is inaccessible to the public. Users can connect to any other computer and exchange electronic mail, send files, and browse web pages. They are separated from the internet by using a firewall. Intranets are used by organisations to manage projects, offer employee information, distribute data and information, and for internal communication.
2. Internet:
It uses the standard Internet Protocol Suite (TCP/IP) and is a global system of interconnected computer networks which can link several devices around the world. It is also referred to as the ‘network of networks’ and consists several private, public, business, academic, and government networks. A web browser is a software on the World Wide Web for retrieving, presenting, and traversing information resources.Â
3. Email:
John Von Neumann invented the email or electronic mail. It is used to transfer data from one system to another system in the form of images, texts, and multimedia messages. Each device is assigned a numerical label called IP address and Internet Protocol address participating in a computer. IP address is unique for evert computer and acts as an identifier for a computer.
4. Audio Conferencing:
It is used by two or more people to hold an audio call from different locations. It is used as a conference bridge. Instead of directly dialling one another, participants can dial into a central system to connect with others. It achieves communication and collaboration simultaneously.Â
5. Video Conferencing:
It helps two or more people to conduct live visual conferences. It is technology-enables and connects people living in different locations. It facilitates transmission of high-quality audio, text messages, static images, motion videos, and the like in different locations.
