Computer Networks and its type

In a Telecommunication terminology, when computer devices share or exchange its data via data-link, we say computers are connected to each other. These connection could be via wired or wireless media. Each communication point between two devices are called network nodes where data transmit from one point to the other. These nodes are hosts like computers, mobile devices servers and network hardware as well. Computer networks exchange enormous amount of data in the form of applications, information and services via local workgroup, intranet and internet and shared devices could be computers, printers, servers, fax, mobile devices and others. Every single piece of data is transmitted in the form of signal and these signal are carried away via transmission media. There are some communications protocols or algorithms are used to route the network traffic, so that the data can be transmitted as early as possible to the destination end.

Networks can be divided into two types:

(A) Peer-to-Peer Network: In this type of network each computer is connected and share their resources without using a separate server. Peer-to-Peer or sometimes said as Point-to-Point networks, as computers are directly connected to each other via communication media. Peer-to-Peer network is used is file sharing services. It is well suitable when network size is moderate.

(B) Client Server Network: In this type of network, a client request for the desired service from the server.  Server checks the request from the client, if the service is available it grants its resources to the client or else it will say resource unavailable. This type of network is used in large organisation where data or information is precious. It is used in Database Management System, Network Management and other types of such resources.
