TCP and UDP, A Comparison

TCP vs. UDP: Exploring the Protocols of Data Transfer

When it comes to networking and data communication, two fundamental protocols stand out: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). These protocols are the foundation of the internet and play crucial roles in ensuring data is transmitted reliably and efficiently across networks. In this article, we will delve into the world of TCP and UDP, explaining their differences and when to use each one.

TCP: Reliability at its Core

Transmission Control Protocol, or TCP, is often referred to as a connection-oriented protocol. It provides a high level of reliability in data transmission by establishing a connection between the sender and the receiver before any data is exchanged.

Key characteristics of TCP

Reliability: TCP guarantees that data sent from one end will be received accurately and in the correct order by the other end. If any packets are lost or arrive out of order, TCP will retransmit them until the data is correctly received.

Error checking: TCP uses error-checking mechanisms to ensure data integrity. It verifies that the data received matches what was sent, reducing the likelihood of corrupted information.
