Asynchronous Transfer Mode (ATM) networking is the newest topology available at this time. unlike others, it can carry both voice and data over network wire or fiber. ATM transmits all packets as 53-byte cells, that have a variety of identifiers on them to determine such things as quality of service. Quality of Service is similar…
FDDI (Fiber Distributed Data Interface) is another ring-based network, and unlike Token Ring, it is implemented without hubs, although you can use devices called concentrates to perform a similar function. FDDI uses fiber optic cables to implement very fast, reliable networks. What is Fiber Distributed Data Interface (FDDI)? FDDI is a high-performance fiber optic token…

Internet layer is used for routing and providing a single network interface to the upper layer. routing is complex and important, and it is the job of the Internet layer to carry it out. The protocol IP is so integral to this layer, the very name of it is the name of the layer itself….
Internet Protocol (IP) is a connectionless, datagram protocol. that works at the network layer. IP packets are also called IP datagrams. IP uses packet switching. it performs route selection by using dynamic routing tables that are referenced at each hop. the packets making up a message could be routed differently through the internetwork depending on…
The Transmission Control Protocols (TCP) or Internet Protocols is an industry-standard protocol suite for wide area networks (WANs) developed in the 1970s and 1980s by the U.S. Department of Defense (DoD). TCP/IP is a routable protocol that is suitable for connecting dissimilar systems (such as Microsoft Windows and UNIX) in heterogeneous networks. It is the…
