Computer Network

Is a group of network that connects together in a way that allows information to be exchanged between the computers.

Packet

A packet is collection of data that can be used by computers which need to communicate with each other, usually as part of a network.

Local area network (lan)

A LAN is a network of computers that are in the same general physical location, usually within a building or a campus. If the computers are far apart (such as across town or in different cities), then a Wide Area Network (WAN) is typically used.

wide area network (wan)

 Wide area network (WAN) technologies connect a smaller number of devices that can be many kilometers apart.

node

A node is anything that is connected to the network. While a node is typically a computer, it can also be something like a printer or CD-ROM tower.

Media access control(msc)

Its a physical address of any device  which is made up of two equal parts, is 6 bytes long. The first 3 bytes identify the company that made the NIC. The second 3 bytes are the serial number of the NIC itself.

ip address

IP address is short for Internet Protocol (IP) address. An IP address is an identifier for a computer or device on a TCP /IP network.

bus topology

A bus topology is a topology for a Local Area Network (LAN) in which all the nodes are connected to a single cable. The cable to which the nodes connect is called a "backbone". If the backbone is broken, the entire segment fails. ... The bus topology is e.g. used by Ethernet networks.

ring topology

A ring topology is a network configuration in which device connections create a circular data path. Each networked device is connected to two others, like points on a circle. ... Most ring topologies allow packets to travel only in one direction, called a unidirectional ring network.

network token

In networking, a token is a series of bits that circulate on a token-ring network. When one of the systems on the network has the "token," it can send information to the other computers. Since there is only one token for each token-ring network, only one computer can send data at a time.

star topology

A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down.

tree topology

A tree topology is a special type of structure in which many connected elements are arranged like the branches of a tree. For example, tree topologies are frequently used to organize the computers in a corporate network, or the information in a database.

protocol

A network protocol defines rules and conventions for communication between network devices. Network protocols include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify how data is packaged into sent and received messages.

peer-peer architeture

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 architecture is an architecture of a computer network in which many clients (remote processors) request and receive service from a centralized server(host computer). ... This computing model is especially effective when clients and the server each have distinct tasks that they routinely perform.
