Computer Networks

Ethernet in computer networks is wired technology we use to connect computers in a local area network (LAN), metropolitan area network (MAN), and wide area network (WAN). Bob Metcalfe & David Boggs invented Ethernet in 1976 at Xerox’s PARC (Palo Alto Research Centre). However, it was introduced for commercial use in 1980. In 1983 “Ethernet” was standardized as “IEEE … [Read more...] about Ethernet in Computer Networks

The sliding window protocol is a flow control protocol for noisy channels. Being a flow control protocol, it prevents the receiver from overwhelming receiver from the data. What is the purpose of Flow Control? The rate at which the sender sends the data and at which the receiver receives the data may vary. However, the receiver maintains a data buffer as it has to process … [Read more...] about Sliding Window Protocol

Transport Layer protocols control and manage the delivery of a message from a process running on the source host to a corresponding process running on the destination host. Well, transport layer protocols can be connectionless where each segment of a message is considered as an independent entity. Or a transport layer protocol can also be connection-oriented where first a … [Read more...] about Transport Layer Protocols

Packet switching is one of the switching techniques that can be used to route the data from source to destination in a switched network. A switched network uses switches to connect multiple devices to form a large network. In a switched network, there can be numerous paths from source to destination. The switching technique identifies the best path among these multiple … [Read more...] about Packet Switching

A wired local area network is a local area network where the connectivity between different components or elements of the LAN is done using wires and cable. Well to implement the wired LANs various technologies were introduced such as token ring, token bus, FDDI, ATM LANs, and Ethernet. Among all these technologies only Ethernet survived the market as it has the capability … [Read more...] about Wired Local Area Network
