“The layout pattern & connectivity scheme between the devices in a network is called network topology”. It is a virtual shape or structure of the network. Devices on the network are called as nodes. The most common nodes are computers and peripheral devices. Network topology is a virtual illustration of these nodes and their connections using physical cabling. There are a number of different types of network topologies which are broadly divided into two types: Physical Network Topology: Actual Connectivity/Layout as per real cabling & connections Logical Network Topology: Virtual view of the network that member devices see Physical Network Read More …
TCP (Transmission Control Protocol) is “a Connection Oriented Transport Layer (Layer4) protocol for reliable communication between network devices” TCPv4 was published in RFC-793 in 1981 and is still the current version. TCP is a connection oriented full-featured transport layer protocol that provides all the functions needed by a typical application for the reliable transportation of data across an internetwork. TCP is a host-to-host protocol. TCP provides reliable communication with a mechanism called Positive Acknowledgement with Re-transmission(PAR) employing the 3-way Handshake. 3-way Handshake Process TCP uses a process called 3-way Handshake for reliable communication. In 3-way Handshake process, three TCP segments are Read More …
“ TCP/IP Model is a standard reference Model for conceptualising data communications between networks ” The TCP/IP is a practical Model that provides E2E data communication specifying how data should be packetized, addressed, transmitted, routed, and received. It characterizes and standardizes the communication functions of a Network system without regard to its underlying internal structure and technology. It is also called the Internet Model or the DoD Model. TCP/IP is a Vendor Neutral Model. It resolved many problems as described in below. Problem: Before TCP/IP Model, each vendor used to use its own network model to manufacture Network equipment. So, one Read More …
