Computer networking

A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other.

   Packet

In networking, a packet is a small segment of a larger message. Data sent over computer networks*, such as the Internet, is divided into packets. These packets are then recombined by the computer or device that receives them

 Local Area Network (LAN)

A local area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.

Wide Area Network (WAN)

A wide area network is a telecommunications network that extends over a large geographic area. Wide area networks are often established with leased telecommunication circuits.

Node

A node is a basic unit of a data structure, such as a linked list or tree data structure. Nodes contain data and also may link to other nodes. Links between nodes are often implemented by pointers.

Media Access Control (MSC)

Media access control (MAC) is a sublayer of the data link layer (DLL) in the seven-layer OSI network reference model. MAC is responsible for the transmission of data packets to and from the network-interface card, and to and from another remotely shared channel.

 IP Address

a unique string of characters that identifies each computer using the Internet Protocol to communicate over a network.

 Bus Topology

Bus topology, also known as line topology, is a type of network topology in which all devices in the network are connected by one central RJ-45 network cable or coaxial cable. The single cable, where all data is transmitted between devices, is referred to as the bus, backbone, or trunk.

Ring Topology

A ring topology is a network configuration where each networked device is connected to two other devices on either side of it to form a circular “ring” data path. When data is transferred in a ring topology, the data is sent in one direction along the single continuous pathway.

 Network Token

A network token is 16-digit Primary Account Number (PAN) alternative, which is unique for each shopper-merchant pairing. Here are the benefits of making payments with network tokens: Reduced shopper friction and declines because network tokens are maintained and automatically updated by card networks.

Star topology is a network topology in which each network component is physically connected to a central node such as a router, hub or switch. In a star topology, the central hub acts like a server and the connecting nodes act like clients.

tree topology

Tree Topology is a topology which is having a tree structure in which all the computer are connected like the branches which are connected with the tree. In Computer Network, tree topology is called as a combination of a Bus and Start network topology

the official procedure or system of rules governing affairs of state or diplomatic occasions.

Peer-Peer Architecture

Peer-to-peer architecture (P2P architecture) is a commonly used computer networking architecture in which each workstation, or node, has the same capabilities and responsibilities. It is often compared and contrasted to the classic client/server architecture, in which some computers are dedicated to serving others.

Client/Server Architecture

Client-server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients.
