Computer Networks and Communication

A computer network is a collection of two or more interconnected computing devices (computers, printers, servers, etc.) that are linked together using communication channels (wired or wireless) to share data, resources, and information with each other. In s...

Computer networking refers to the practice of connecting two or more computing devices together to share resources, data, and information. The importance of networking can be highlighted through the following points: 1. Resource Sharing Networking allows mu...

--- Network topology refers to the physical or logical arrangement of nodes (computers, devices) and the links (cables, connections) that connect them in a network. It defines how different nodes in a network are placed and interconnected with each other. T...

Transmission media refers to the physical pathway or channel through which data signals travel from a sender to a receiver in a communication network. It is the actual physical environment through which signals are transmitted between devices. Transmission ...

Transmission media is the physical path through which data signals travel from sender to receiver. It is broadly classified into two categories: 1. Guided (Wired) Media 2. Unguided (Wireless) Media --- In guided media, signals are directed and confined alon...

--- (a) Definition Transmission Media is the physical or logical path between a sender and a receiver through which data signals travel from one point to another. Guided media refers to transmission media in which signals are directed and confined along a s...

TCP/IP (Transmission Control Protocol / Internet Protocol) is a set of communication protocols used to interconnect network devices on the internet and other networks. It defines how data should be packaged, addressed, transmitted, routed, and received acro...

--- The Internet is a global network of interconnected computers and networks that communicate with each other using a standard set of protocols (TCP/IP). It is a worldwide system that allows billions of devices to share information and resources across dif...

A network device (also called networking hardware or network equipment) is a physical device used to connect computers, printers, and other electronic devices together so that they can share resources and communicate with each other. These devices facilitat...

A communication protocol is a set of rules and conventions that govern how data is transmitted between devices in a network. The need for communication protocols arises due to the following reasons: 1. Standardization: Different devices from different manuf...
