What is Computer Network
What is Computer Network:
Computer Network is
a telecommunications network that allows computers to exchange data.
How a Computer Network Works:
In computer networks, networked computing
devices pass data to each other along data connections. Data is transferred in
the form of packets. The connections (network links) between nodes are
established using either cable media or wireless media. The best-known computer
network is the Internet.
Computer to Computer Network
Network computer devices that originate, route and terminate
the data are called network nodes.[1] Nodes can include hosts such as personal
computers, phones, servers as well as networking hardware. Two such devices are
said to be networked together when one device is able to exchange information
with the other device, whether or not they have a direct connection to each
other.
Wide area network
Computer networks support applications such as access to the
World Wide Web, shared use of application and storage servers, printers, and
fax machines, and use of email and instant messaging applications. Computer
networks differ in the physical media used to transmit their signals, the
communications protocols to organize network traffic, the network's size,
topology and organizational intent.
