Network in other words, you can say is a ‘web’. So, Computer Network becomes ‘web of computers’. This special kind of web of computers should be designed so intelligently that there should be no mess, not much expensive, secure, efficient and quick in communicating with each other.
For computers to communicate with other computers there
should be some devices which are able to send data (according to its nature) in
medium. Network devices are the components used to connect computers or
electronic devices to communicate in a network of computers.
“Network devices are those devices which
are used to interconnect two or more than two computers with each other to
share data, information, voice, resources and to communicate with each other.”
Network devices are the hardware responsible to send data
on medium and some software, which helps in making a secure and efficient
network. And the software is also used to monitor the traffic of the network
device.
The
network devices and its components which you use in a network depend on the
type of need of the network with efficiency, speedy, secure and cheap.
