Bandwidth
The capability of a transmission medium to transmit the maximum amount of data from one
computer to another over a computer network in a given amount of time is called bandwidth.
A bandwidth is generally in bits per second (bps) or Bytes per second (Bps), Kilobytes per
second (KBps) and Megabytes per second (MBps). There can be various types of bandwidths
which are network bandwidth, data bandwidth, or digital bandwidth.
Devices Required for a Network COMPUTER NETWORKING
There are various types of devices and components required for a network, such as Network
Interface Card (NIC), Hub, Switch, Router, Modem and Network Cable. Let us discuss about
these in detail.
Network Interface Card (NIC)
It is an expansion card that enables a computer to access a network. It allows the 21
computer to connect to a network through a wired or wireless medium.
Hub or Switch NIC
It is hardware device that has various ports to which the computers,
Hub or Switch printers and other networking devices are connected. The main function
of a hub is to direct information around the network and facilitate communication between all
the connected devices.
Router
It is a networking device used to connect and facilitate transfer of data
in the form of packets between two networks. It finds best route for
transmitting data packets over the network. It is located at the gateways
where two networks connect. Router
Modem
It stands for MODULATOR—DEMODULATOR. It is a hardware device that is used
to connect a computer to the Internet via a telephone line or a wireless medium.
It converts data from digital to analog and vice versa. The process of converting
analog signals to digital signals is called demodulation. The process of converting
Modem
digital signals to analog signals is called modulation.
Networking Cable
Networking cable, also known as Ethernet cable, is a transmission medium
that allows to transport information from one place to other place. Ethernet Cable
