Basics of Networking

What is a network? According to Google " a group or system of interconnected people or things" is called network. In computer world computing devices exchange data with each other using connections between nodes. These data links are established over cable media such as wires or optic cables, or wireless media such as Wi-Fi.  In simple words, a network is a communication between two devices sharing some data through cables or wireless media.      Why we need a network? Humans are social animals, devices are too. Devices also need to talk to each other to operate some tasks. Networking of computers helps the network users to share data files. Hardware sharing: Users can share devices such as printers, scanners, CD-ROM drives, hard drives etc. Components of a network: A computer network includes a lot of devices to operate depending upon the distance, mode,  and other technical things you will learn in this blog. Basic components of a network are: Switc

OSI Model

OSI Model . Introduction If you are in the field of networking or you are curious to learn about networking you have heard the term OSI( Open Systems Interconnection ) model. So the OSI model is a reference model which explains how a network works dividing it by seven layers, which we are going to study now. The seven layers of the OSI model. Seven layers of the OSI model[/caption] 1. Physical layer. In the physical layer, there are all the physical connections between the networking devices. Usually, the major problems in networking come here like damaged cables, unplug switches, and many other physical problems. 2. Data link layer. The data link layer is the protocol layer in a program that handles the moving of data into and out of a physical link in a network. 3. Network layer. The network layer is responsible for packet forwarding including routing through intermediate routers. Data is transferred in the form of packets via
