Components of a Computer Network

The basis of computer communication is the computer network. A computer network is a collection of connected computers that can exchange information with each other. Having a well-understood computer network is essential, as well as a well-designed computer network component. 

During today’s lesson, we will clarify our understanding of the components of a computer network. 

 

Components of Networking

The main components necessary to install the software are computer network components. An overview of the elements of a computer network is given below.

 

Server

A server is a computational interface that connects to other computers and users. A “server” is often a computer system that receives requests for online documents and returns the data to the client.

 

Client

The term “client” refers to the device that receives requests and responses from the server. When a server and its clients collaborate on a computer, a client network is formed.

 

Transmission Media 

In a network, data is transported from one device to another through transmission means. Physical transmission media and wireless transmission media are the two forms of transmission media. Cables and wires, such as fiber optic cables and coaxial cables, are used in physical transmission; unguided media, such as infrared waves, electromagnetic fields, and microwaves, are used in wireless transmission.

 

Network Interface Card

Network Interface Controllers, Network Adapters, Local Area Network Adapters, and Physical Network Interfaces are also referred to as network interface cards (NICs). Network interface cards are hardware components that allow computers to communicate with one another across a network. A computer cannot connect to the network without a network interface card (NIC).

 

Hub

Multiple Computers can share a network thanks to the hub. It’s comparable to how distribution centers work. The hub is used in most computer networks to transfer data across a cable from one machine to another. The hub receives this request and sends it to all nodes in the network.

 

Switch

A switch connects devices to networks, allowing data to be exchanged between them. These switches have more complex functions than network hubs, in addition to being identical to them. It does not broadcast all information throughout the network, unlike hubs.

 

Router

Routers are hardware components of a network. Network routers use logical addresses to send packets across the network, operating at the network layer of OSI (Open system interconnection).

 

Modem

The modulator is the full form of the modem. When digital signals are converted into analog signals, they are called modulated signals. Connecting a computer device, such as a router or switch, to the Internet is facilitated by these components.

 

Repeater

Repeaters are powerful network components that amplify signals. As a result, the signal strength remains stable over a long period.

 

Bridges

A bridge is a device with the capability of filtering content depending on the source and destination MAC addresses. A bridge connects two LANs (Local Area Networks) that use the same protocol. This device is at the data link layer, according to the OSI Model.

 

Gateway

An internet gateway is a piece of hardware that connects two networks. It can also be a router, firewall, server, or any other device that allows data to flow between networks. Gateways are used to connect networks that use various protocols.

This is all part of the networking components.

 

How to Create a Computer Network

You will have to follow some steps listed below to set up a computer network.

 

Connect the Router 

Routers are devices that connect your computer network to the Internet. Furthermore, it is how all of your devices connect. A network adapter is required for all devices that connect to the router.

 

Access the Router Interface and locked it Down

The next step is to log into the router’s interface. This is performed by connecting a laptop to the router and using the browser interface.

 

Configure Security and IP Addressing

After you’ve accessed the router, you’ll need to set up the security, SSID, and IP address. It is critical to secure security, lest your neighbor use your bandwidth and possibly your data. The IP address is required for communication between your network’s devices and the router.

 

Managing to share and Controlling

After you’ve built up your network, you can arrange it so that anyone can use it. By creating a HomeGroup, an intuitive approach to share files, it’s simple to set up a workgroup with Windows 7 users. A HomeGroup is a collection of computers that share files and printers through the internet.

Create a User Account

Users must log in to most corporate networks by inputting their username and password. Users are given accounts in corporate IT networks so that they can keep track of who is accessing the network and when they are accessing it. If you have a HomeGroup or Workgroup set up on your computer network, you may accomplish the same thing.

These are some ways that a computer network can be set up.

 

Final Note 

 

For a computer network to run smoothly, there are a variety of network components to consider. The goal of this lesson is to provide you with a proper understanding of networking components.
