computer hardware or software is interconnected for sharing one or more other computers. This is the connected system to the computer network.
The connection between computers can be different. For example, you can connect your computer to a building in a building with computers or other cable computers. It can be a system of network coordination.
But sometimes the need for connecting between different distances of computers. In this case, it is not possible to connect with the cable or with it. For example, the connection between the computations of different branches of a bank. It is not possible to connect to Sylhet branch computer with the Dhaka branch computer and connect it directly with him or the cable. But networks can be set up between computers using a telephone line modem or satellite.
Types of Computer Networks
Various types of networks have been created according to the needs of users and organizations. For example,
Ownership basis:
Ownership network type 2
Private Network
Public (Public Network)
Based on Topology:
Based on Topology, the network is mainly of four types
Star Topology

Mesh Topology
Functions:
Networks are mainly divided into two categories based on functionalities.
Per-to-Per Network
Client Server Network
Based on workspace:
Depending on the circumference of the workspace, the network can be divided into 3 sections
Local Area Network
Metropolitan Area Network
Wide Area Network
Based on switching
The network is divided into 3 sections based on the switching strategy
Circuit switched network
Message Switched Network
Packet Switch Network
Based on the construction strategy:
Based on the construction strategy, the network is mainly of 2 types.
Point to Point Network
Broadcast or Multipoint Network
