võrguprotokollid

Võrguprotokollid, or network protocols, are standardized rules and procedures that govern data communication between devices on a network. They define how data is formatted, transmitted, and received, ensuring that devices can understand and interpret each other's messages. Protocols operate at various layers of the network model, such as the physical, data link, network, transport, session, presentation, and application layers.

The most well-known network protocol is the Internet Protocol (IP), which is responsible for addressing and routing packets of data across networks. Another crucial protocol is the Transmission Control Protocol (TCP), which provides reliable, ordered, and error-checked delivery of data between applications. Together, IP and TCP form the foundation of the Internet's communication infrastructure.

Other essential protocols include the Hypertext Transfer Protocol (HTTP) and its secure version (HTTPS), which are used for transmitting web pages and other data on the World Wide Web. The File Transfer Protocol (FTP) is used for transferring files between computers, while the Simple Mail Transfer Protocol (SMTP) handles the sending of emails. The Domain Name System (DNS) translates human-readable domain names into IP addresses, enabling users to access websites using easy-to-remember names.

Network protocols are designed to be interoperable, meaning they can work together seamlessly across different hardware and software platforms. This interoperability is crucial for the global connectivity that the Internet provides. Protocols are continuously evolving to meet the growing demands of modern networks, incorporating new technologies and improving existing ones to ensure efficient and secure data communication.
