Hi friends mai aaj networking ke bare me batane jarahu.
Networking
Definition-What does Network mean?
A network, in computing, is a group of two or more devices that can communicate. In practice, a network is comprised of a number of different computer systems connected by physical and/or wireless connections. The scale can range from a single PC sharing out basic peripherals to massive data centers located around the World, to the Internet itself. Regardless of scope, all networks allow computers and/or individuals to share information and resources.
Computer networks serve a number of purposes, some of which include.
Early computer network of the late 1950s included the U.S. military's Semi-Automatic Ground Environment (SAGE) and the commercial airline reservation system called the Semi-Automatic Business Research Environment (SABRE). Based on designs developed in the 1960s. The Advanced Research Projects Agency Network ( ARPANET ) was created in 1969 by the U.S. Department of Defense and was based on circuit switching- the idea that a single communication line, such as a two-party telephone connection, deserves a dedicated circuit for the duration of the communication. This simple network evolved into the present day
Some of the basic hardware components that can be used in networks include.

Computer networks serve a number of purposes, some of which include.
- Communications such as email, instant messaging, chat rooms, etc,
- Shared hardware such as printers and input devices
- Shared data and information through the use of shared storage devices
- Shared software, which is achieved by running applications on remote computers

Some of the basic hardware components that can be used in networks include.
- Interface Cards: These allow computers to communicate over the network with a low-level addressing system using media access control (MAC) addresses to distinguish one computer from another.
- Repeaters: These are electronic devices that amplify communication signals and also filter noise from interfering with the signals.
- Hubs: These contain multiple ports, allowing a packet of information/data to be copied unmodified and sent to all computers on the network.
- Bridges: These connect network segment, which allows information to flow only to specific destinations
- Switches: These are devices that forward, make forwarding decisions and otherwise filter chunks of data communication between ports according to the MAC addresses in the packets of information
