A computer network is a system in which multiple computers allow nodes to share resources that are connected to each other to share information and resources with the internet being the most famous computer network worldwide.
In networking terms, we have networked computing devices that exchange data with each other using a data link.
One can share resources from one computer to another, create files and store them in one computer, access those files from the other computers connected over the network and connect a printer, scanner, to one computer within the network and let other computers of the network use the machines available over the network.
The hardware that are required to setup a computer network include network cables, routers and network card and they are the physical transmission medium with networks comprise additional basic building blocks for the system.
Network cables are used to connect computers and the most commonly used cable is called the Category 5 cable RJ-45.
A computer can be connected to another one with a serial port but if we need to connect many computers to produce a network, then we need to use a central body to which other computers, printers, scanners that can be connected and then this will manage or distribute network traffic.
A router is a type of device which acts as the central point among computers and other devices that are part of a network and it comes with ports and computers and other devices are connected to a router using network cables.
Routers are also found in wireless modes using which computers can be connected without any physical cable.
Network card is a major component of a computer without which a computer cannot be connected over a network.
It is called the network adapter or the Network Interface Card and are of two types : Internal and External Network Cards.
Wireless network card need to be inserted into the motherboard but no network cable is required to connect to network
USB card are easy to use and connect through the USB port and computers automatically detect and can install the drivers required to support the USB network card automatically.
It is important to note that network security is used on a variety of computer networks, both public and private, to secure daily transactions and communications among businesses and individuals alike.

It is called the network adapter or the Network Interface Card and are of two types : Internal and External Network Cards.
The motherboard has a slot for internal network card where it is to be inserted.
Internal network cards are of two types that include Peripheral Component Interconnect (PCI) connection while the other uses Industry Standard Architecture (ISA)with network cables that are required to provide network access.
External network cards include: Wireless and USB based.Wireless network card need to be inserted into the motherboard but no network cable is required to connect to network
USB card are easy to use and connect through the USB port and computers automatically detect and can install the drivers required to support the USB network card automatically.
