Computer Network For Beginners - December 2022

A computer network is a collection of two or more connected computers. Networks are useful for sharing resources, such as files, printers, and Internet connections. Networks can also be used to communicate with other people and organizations.

There are a variety of different types of computer networks, each with its own advantages and disadvantages. The most common type of computer network is the local area network (LAN), which connects computers within a small area, such as a home, office, or school.

Another common type of computer network is the wide area network (WAN), which connects computers over a large geographical area, such as the Internet. WANs can be used to connect multiple LANs together, forming a larger network.

There are also a variety of different network protocols, which are the rules that computers use to communicate with each other. The most common network protocol is Ethernet, which is used in LANs and WANs.

To set up a computer network, you first need to purchase or build some network devices, such as a network router, network switch, and network adapters. You then need to install and configure the network devices, and connect the devices to each other.

Once the network devices are set up, you need to install the network operating system (NOS), which is the software that controls the network. The NOS will allow you to create and manage network connections, share files and printers, and access the Internet.

The last step is to configure the network settings on each computer. This will allow the computers to connect to the network and access the resources that are shared on the network.

Now that you know about computer networks, let’s take a look at some of the different types of networks that are available.

LANs

LANs are small, localized networks that connect computers within a small area, such as a home, office, or school. LANs are typically built with Ethernet, which is a network protocol that uses cables to connect the computers.

LANs are popular because they are easy to set up and are ideal for small networks. They are also faster and more reliable than other types of networks, such as WANs and the Internet.

WANs

WANs are large, geographically dispersed networks that connect computers over a wide area. WANs can be used to connect multiple LANs together, forming a larger network.

WANs are popular because they can be used to connect to the Internet, which gives the users access to a large number of resources. WANs are also slower and less reliable than LANs.

The most common type of WAN is the Internet, which connects computers all over the world. Other common types of WANs include telephone networks and satellite networks.

Network Protocols

Network protocols are the rules that computers use to communicate with each other. The most common network protocol is Ethernet, which is used in LANs and WANs.

Other common network protocols include TCP/IP, which is used in the Internet, and ATM, which is used in telephone networks.

Network Devices

Network devices are the hardware that is used to connect the computers in a network. The most common type of network device is the network router, which is used to connect the computers in a LAN.

What is computer network beginner?

A computer network is a system in which two or more computers are connected to each other to share resources. A computer network can be as simple as two computers connected by a cable, or it can be as complex as the Internet.

A computer network can be used for a variety of purposes, including sharing files, printers, and internet access. Networks can also be used for communication, such as chat programs or video calls.

There are a variety of different types of computer networks, including local area networks (LANs), wide area networks (WANs), and the Internet.

A LAN is a network that is limited to a specific area, such as a building or campus. LANs are usually connected by cables, and are used for sharing files, printers, and internet access.

A WAN is a network that spans a large area, such as a city, state, or country. WANs are usually connected by telephone or satellite connections, and are used for communication and file sharing.

The Internet is the largest computer network in the world. It is a global network that connects millions of computers together. The Internet is used for communication, file sharing, and for a variety of other purposes.
