In computer networking, an "endpoint" refers to a device or a node where data originates, terminates, processes and passes through within a network. Endpoints can be various types of devices, including computers, servers, printers, IoT devices, IP Phones and network peripherals. These devices communicate with each other over a network to exchange data traffic to perform specific tasks. 

There are different types of end points we can see in computer networks, like client endpoint, server endpoint etc. 

Example of Client Endpoints: Devices such as computers, smartphones, and tablets that initiate requests for services or resources from servers. 

Example of Server Endpoints: Devices such as web servers, email servers, and file servers that respond to client requests and provide services or resources. 

Client and server endpoints work together to facilitate communication and enable the exchange of data and services within a network. They represent two fundamental roles in client-server architecture, where clients request resources or services from servers, which in turn provide those resources or services to clients. 

Endpoints play a crucial role in computer networking, serving as the starting and ending points for data transmission within networks.
