Frequently Asked Questions About Network Protocols
What are network protocols, and what do they do?
Network protocols are rules and conventions governing communication between devices in a network. They dictate how data is transmitted, including the speed of transmission, the size of the message, and the methods used for error checking. They also determine whether the transmission is synchronous or asynchronous.
How are devices addressed in networks?
Devices are addressed using unique identifiers called IP addresses, and these addresses are used to route data to the correct device.
What are some standard protocols used in networking?
TCP/IP is commonly used on the internet, and the OSI (Open Systems Interconnection) model is the most widely used network layering model. It separates the functions of a network into seven layers, each with its own set of protocols and rules.
How is the concept of layering applied to networks?
The OSI (Open Systems Interconnection) model is the networks' most widely used layering model. It separates the functions of a network into seven layers, each with its own set of protocols and rules.
How is data transmitted using the TCP/IP suite of protocols?
The TCP/IP (Transmission Control Protocol/Internet Protocol) suite of protocols is responsible for routing data packets, ensuring their integrity, and reassembling them at their destination. The TCP protocol handles error checking and recovery, while the IP protocol handles routing and addressing.
