Socketrajapinnat, often translated as socket interfaces or socket APIs, are a fundamental concept in computer networking that enable communication between different processes, often across different machines connected by a network. They provide a standardized way for applications to send and receive data over a network.

At its core, a socket is an endpoint for sending or receiving data. Think of it as a doorway through which information can pass. The socket interface defines a set of functions and data structures that programmers use to create, configure, and manage these communication endpoints. This interface abstracts away the complexities of the underlying network protocols, such as TCP/IP, allowing developers to focus on the application logic rather than low-level network details.

Common socket operations include creating a socket, binding it to a specific network address and port, listening for incoming connections (for server-side sockets), establishing a connection to a remote socket (for client-side sockets), sending data, and receiving data. The most prevalent socket APIs are those provided by the operating system, such as Berkeley sockets (often referred to as the POSIX sockets API) and Winsock for Windows.

These interfaces are crucial for a vast range of internet applications, including web browsing, email, file transfer, and online gaming. They form the bedrock of distributed computing, allowing disparate systems to interact and share information seamlessly.
