Difference between TCP and HTTP

Difference between TCP and HTTP

There are many different network protocols in use today, and it can be difficult to keep them all straight. In this post, we’ll take a look at two of the most common ones: TCP and HTTP. We’ll discuss the differences between them, and explain why TCP is more appropriate for some applications than HTTP.

What is TCP?

TCP, or Transmission Control Protocol, is a network protocol that helps ensure reliable, error-free communication between devices on a network. TCP uses a three-way handshake to establish a connection and then breaks data down into small packets that are transmitted over the network. If any of the packets are lost or corrupted, TCP will automatically retransmit them until they are received correctly. This makes TCP an essential part of many internet applications that require reliable data transfer, such as email and file sharing. While TCP is not the only network protocol available, it is one of the most commonly used and is an important part of how the internet works.

What is HTTP?

HTTP, or Hypertext Transfer Protocol, is the primary protocol used for communication on the World Wide Web. HTTP is a request-response protocol, meaning that a client sends a request to a server and the server returns a response. HTTP requests can be of several types, including GET, which requests data from a server; POST, which sends data to a server; and HEAD, which requests metadata from a server. HTTP responses typically include the requested data as well as metadata about the data, such as the type of content and the length of the data. HTTP is designed to be simple and efficient, and it forms the foundation of communication on the Web.

Difference between TCP and HTTP

TCP and HTTP are two of the most commonly used protocols on the internet. TCP, or Transmission Control Protocol, is responsible for establishing and maintaining connections between devices. HTTP, or Hypertext Transfer Protocol, is responsible for transferring data between devices. TCP is a lower-level protocol than HTTP, which means that it is responsible for managing connections but not for actual data transfer. HTTP is built on top of TCP and is responsible for handling data transfer. Because TCP is a lower-level protocol, it is generally faster and more reliable than HTTP. However, HTTP is easier to use and more widely supported than TCP, which makes it the preferred protocol for most applications.


In short, TCP is a more reliable protocol for data transmission because it guarantees delivery of packets between devices. HTTP is better suited for web browsing and doesn’t guarantee packet delivery. If you’re looking to build an application that needs guaranteed packet delivery, TCP is the way to go. Otherwise, HTTP will likely be just fine.
