TCP – Everything You Need to Know

Transmission Control Protocol (TCP) is one of the fundamental protocols in the internet protocol suite handling how data is transmitted between network devices. Whether you’re managing websites, configuring servers, or simply browsing online, understanding this protocol is crucial. In this article, we’ll cover everything you need to know about it, how it works, and why it matters.

What is TCP?

TCP (Transmission Control Protocol) is a core protocol in the TCP/IP suite, responsible for ensuring reliable data transmission between devices over a network. Unlike UDP (User Datagram Protocol), Transmission Control Protocol provides error checking, data integrity, and order, making it ideal for applications where data accuracy is critical—such as web browsing, file transfers, and email.

UDP: What is it and How Does it Work?

The UDP holds a special place among all networking protocols due to its simplicity and efficiency. Despite being overshadowed by the more well-known Transmission Control Protocol (TCP), it plays a critical role in various applications where speed and efficiency outweigh the need for reliability. In today’s article, we will explore what it is, how it works, and why it is essential in the realm of data communication.

Understanding UDP

User Datagram Protocol (UDP) is one of the core protocols of the Internet Protocol (IP) suite. Defined by RFC 768, it was designed to facilitate fast and efficient data transmission. Unlike TCP, which is connection-oriented and ensures reliable delivery of data packets, UDP is connectionless and does not guarantee delivery, order, or error checking. This trade-off allows for achieving lower latency and reduced overhead, making it ideal for specific use cases.
