This is the computer network that connects your friends computer to your computer.
Now when a computer is connected to another computer, some helpful devices are needed, like you might have used a modem or used a router! These are network devices.
So let's look at the computer network definitions a bit ,
The computer network is the integrated system of hardware and software used for transmitting and processing data between multiple computer in any distance.
Objective of computer networks
Well. I got the network ideas. But the computer network is not built like that anymore. It certainly has some purpose. Let's see the motive a little bit.
Types of network
In the words sharing is caring the need to share information in the modern world docs not require you to rcncw it. We share a lot of information white each other every day. With the importance of sharing information, many large computer networks have developed in the modern world. Some of these areas are spread over many places, and some of the smaller networks are also there .Based on the geographic cxpansion of the network, the network is divided into five parts based on the distance between one computer and another computer.
LAN MAN WAN
1.composed of very limited area. I. The city consists of wide area like the city. I. Extensions are not bound in specific boundaries.
2.Expansion in I. 2.Expansion in 100km.2.The expansion can be more than 100km or across the globe.
3.Wired medium is used. 3.Both wired and wireless are used. 3.Both wired and wireless are used.
4.Single network. 4.A network considering of multiple LANs. 4.A large number of LANs
A network consisting of MAN .
5.The cost is relatively less. 5.Spend more than LAN. 5.Spend more than LAN and MAN.
6.The spend of data flow can range from 10Mbps to 100Mbps .6.Data flow speed 10.
From Mbps up to 10Gbps .6.Data flow can range form 100Mbps to 100Gbps..
