A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). Ethernet switch devices were commonly used on home networks before home routers became popular; broadband routers integrate Ethernet switches directly into the unit as one of their many functions. High-performance network switches are still widely used in corporate networks and data centers. Advantages Switches have increased available network bandwidth. There is reduced workload

Transmission Control Protocols or TCP is among the key methods utilized in Internet Protocol Suites. TCP has got two end systems, a web browser and a web server from which it operates. TCP provides delivery of a stream of bytes from a program on one computer system to another. Internet Protocols operate at a lower level compared to TCP. An IP is used for data transmission across a packet switched internetwork. In X on and X off signals, the X means transmitter. These types of signals are used to
