Computer network definition

A computer network is when two or more computers are interconnected and can exchange data and share resources with each other.  👍

                        Types of Computer Network

                        1. Computer network devices

                        2. Computer network media

                        3. Computer network topology

Computer Network devices, also known as networking hardware, are devices that allow hardware's on a computer network to communicate, interact, and connect with one another. For example Repeater, Hub, Bridge, Switch, Routers, Gateway, etc.

Computer Network Devices

Computer Network Media

Network media refers to the communication channels used to interconnect nodes on a computer network. Typical examples of network media include wired (copper coaxial cable, copper twisted pair cables, etc.) and wireless (radio waves used in wireless data communications networks, etc.)

Network Topology

A Network Topology is the physical and logical arrangement of nodes and connections in a network. Nodes usually include devices such as switches, routers and software with switch and router features. Network topologies are often represented as a graph.

Network Transmission Media

There are two types of transmission media, namely guided and unguided. Guided transmission media are cables like twisted pair cables, coaxial cables, and fiber optic cables. Unguided transmission media are wireless, such as infrared, radio waves, and microwaves.
