Types of Protocol
- Network Layer Protocols : Network layer protocols operate in the network layer which is also known as the Layer 3 of the network architecture. Network layer protocols are responsible for packet routing, forwarding, and addressing of data packets throughout the network. IP and ICMP are the network layer protocols.
- Transport Layer Protocols: Transport layer protocols work in the transport layer which provides end-to-end service ensuring data transfer across apps on different devices. TCP and UDP are the most popular transport layer protocols.
- Application Layer Protocol: Application layer protocol working in the application layer of the network architecture provides communication between applications running on different devices. The application layer protocols enable cross-device communication. They format, exchange, and interpret application data. HTTP, FTP, and SMTP are examples.
- Wireless Protocols: Wireless protocols basically used in wireless communication which enables data transfer through wireless networks. Bluetooth, Wi-Fi, and LTE protocols are examples.
- Routing Protocols: Routing protocol establishes the best/optimal network pathways throughout the network for fastest data transmission. Routers share information to develop and maintain routing tables. RIP, OSPF, and BGP are examples.
- Security Protocols : security protocol protects data confidentiality, integrity, and authenticity while transmission of data over the network. They include SSL and TLS, encryption methods, and authentication protocols for providing data security.
- Internet Protocols : IP identifies devices uniquely. Internet protocol provides data communication through routing and forwarding data packets from one device to another by unique addressing scheme.
Protocol and Standard in Computer Networks
Protocols and standards are important in computer networks. They are like the rules and guidelines that allow different devices and systems to communicate and work together smoothly. Protocols define how data is sent, received, and processed, while standards ensure that various technologies are compatible with each other. This coordination is critical for the Internet and other networks to function constantly and efficiently.
Network protocol ensures that different technologies and components of the network are compatible with one another, reliable, and able to function together. In this article, we are going to discuss every point about protocols and standards in computer networks.
