A networking device that connects multiple ports or systems to the network and transfers the information to all the devices in a network. Also known as " d u m b " switch. Switched communication networks are those in which data transferred from source to destination is routed between various intermediate nodes. Switching is the technique by which nodes control or switch data to transmit it between specific points on a network. There are 3 common switching techniques: Circuit Switching. Unmanaged switches simply allow Ethernet devices to communicate with one another by providing a connection to the network. Unmanaged switches are truly plugged and play devices, meaning you simply have to plug them in for them to work.

HISTORY OF INTERNET

In 1969, the University of California at Los Angeles and the University of Utah were connected with the beginning of the ARPANET (Advanced Research Projects Agency NETwork) using 56 kbit/s circuits, which is sponsored by U.S. (United States) Department of Defense (DoD). The goal of this project was to connect computers at different Universities and U.S. (United States) defense.

In mid 80’s another federal agency, the National Science Foundation (NSF) created a new high capacity network called NSFnet (National Science Foundation Network), which was more capable than ARPANET. The only drawback of NSFnet was that it allowed only academic research on its network and not any kind of private business on it. Now, several private organisations and people started working to build their own networks, named private networks, which were later (in 1990’s) connected with ARPANET and NSFnet to form the Internet. The Internet really became popular in 1990’s after the development of World Wide Web (WWW).

The Internet has gained popularity and emerged as an important and efficient means of communication. The term Internet is derived from the words ‘interconnection’ and ‘networks’. A network is a collection of two or more computers, which are connected together to share information and resources. The Internet is a worldwide system of computer
networks, i.e. network of networks. Through Internet, computers become able to exchange information with each other and find diverse perspective on issues from a global audience. Most of the people uses Internet for sending and receiving E-mail and net surfing for retrieving information.
