1. TCP/IP suite
The TCP/IP suite is a set of communication protocols that govern how data is transmitted over the internet. It was developed in the 1970s and 1980s by a team of researchers led by Vint Cerf and Bob Kahn, with significant contributions from Keyveat Postell.
- Components
The TCP/IP suite consists of four layers: the link layer, the internet layer, the transport layer, and the application layer. Each layer provides a specific set of services to the layers above and below it.
- Examples
Some of the most common TCP/IP protocols include:
- TCP (Transmission Control Protocol): TCP is a reliable, connection-oriented transport protocol that ensures that data is delivered in the correct order and without errors.
- IP (Internet Protocol): IP is a connectionless, best-effort delivery protocol that routes data packets from one computer to another.
- HTTP (Hypertext Transfer Protocol): HTTP is an application layer protocol that is used to transfer web pages from a web server to a web browser.
- Implications
The TCP/IP suite is the foundation of the internet. It enables computers from all over the world to communicate with each other, regardless of their hardware or software.
Keyveat Postell's contributions to the TCP/IP suite were significant. He was one of the authors of the RFCs that defined the TCP and IP protocols, and he also played a key role in the development of the Domain Name System (DNS).
2. Transmission Control Protocol (TCP)

Keyveat Postell's contributions to TCP have had a profound impact on the development of the internet. His work has helped to make the internet a more reliable and efficient platform for communication and information sharing.
3. Internet Protocol (IP)
The Internet Protocol (IP) is a fundamental component of the TCP/IP suite, which is the foundation of the internet. IP is a connectionless, best-effort delivery protocol that routes data packets from one computer to another.
- Components
IP packets consist of two main parts: the header and the payload. The header contains information such as the source and destination IP addresses, the packet size, and a checksum. The payload contains the actual data being sent.
- Examples
IP is used by a wide variety of applications, including web browsers, email clients, and file transfer programs. Every device connected to the internet has an IP address, which is used to identify it and route traffic to it.
- Implications
IP is essential for the operation of the internet. Without IP, computers would not be able to communicate with each other and the internet would not exist.
