Network Programming is a field of computer science that focuses on writing software that enables communication between computers over a network. This involves creating applications that can send and receive data, allowing devices to share information and resources. Common protocols used in network programming include TCP/IP, UDP, and HTTP, which define how data is transmitted and received. In network programming, developers often use languages like Python, Java, or C to create client-server applications. A client requests services or resources from a server, which processes the request and sends back the appropriate response. This interaction is fundamental to many online services, such as web browsing and file sharing.
