The computer network are playing an important role in providing services to large organization as well as to individual person. A network is a group of interconnected computers that allows to share information and resources (such as printers) from one computer to another. A network with the right software helps to increase employee productivity and reduce costs.Network consists of Nodes (computers),connecting medium (wired or wireless),specialized network equipment like routers or hub. Routing is the act of moving information across an internetwork from a source to a destination. Routing occurs in Layer 3 ie.Networking layer which distinguishes it from bridging that occurs in Link layer of the OSI model. The two basic activities of routing:It determines the optimal routing paths and transports information in groups (packets) through an internetwork. Path determination takes place with the help of various Routing Algorithms. Routing algorithms initialize and sustain routing tables, which contain route information. When a router receives an incoming packet, it checks the destination address and attempts to associate this address with a next hop.Switches are another vital part of many networks because they speed things up. Switches allow different nodes of a network to link directly with one another in a smooth and efficient manner. Switches providing a separate connection for individual node’s in a company\'s internal network are called LAN switches. A LAN switch generates a series of instant networks that contain only the two devices communicating with each other at that particular moment. Hence in this report we will study the usages of Routing and Switching in the arena of Networking.
