Verkkopäätepisteenä describes a network endpoint. In computing, a network endpoint is a communication point or interface between a network device and a communication link. It is the point where a message enters or exits a network. A network endpoint can be a physical device, such as a computer, router, or server, or it can be a logical construct, such as a port number on a device.

The concept of a network endpoint is fundamental to understanding how data is transmitted across networks. For example, when a user accesses a website, their computer acts as one network endpoint, and the web server hosting the website acts as the other. The communication between these two endpoints is managed through network protocols, such as TCP/IP, which define the rules for data exchange.

Network endpoints are identified by unique addresses. On the internet, these are typically IP addresses, which specify the location of a device on the network. In addition to an IP address, a port number is often used to distinguish between different applications or services running on the same device. This combination of IP address and port number forms a socket, which uniquely identifies a specific endpoint for network communication. Understanding network endpoints is crucial for network administration, security, and the development of networked applications.
