Understanding and analyzing the intricate processes online is critical.
Three specific protocols are commonly associated with fetching information. This helps streamline the data and ensures it is processed correctly.
The three are TCP vs UDP vs HTTP.
TCP refers to a connection-based protocol, which sends a message from one computer to another. This is commonly associated with HTTP, which interacts between client and server (i.e. video encoding). In comparison, UDP is not a connection-based protocol. Instead, it passes a load of packets from one program to another in a connectionless transfer (i.e. gaming).
For the most part, each protocol has a purpose.
It’s important to understand the use case and then determine what is best for your situation. For example, TCP connections work well when reliability is of utmost importance such as when encoding videos.
On the other hand, UDP works better for faster transfers such as when gaming. This is when speed becomes the most important factor.
This article is going to compare TCP vs UDP vs HTTP to take a better look at what each one is all about.

Comparing TCP Vs UDP Vs HTTP
1. Reliability
TCP or Transmission Control Protocol is noted for being the most reliable solution.
The reason it is reliable comes down to how the transfer of information occurs from start to finish. In this case, the protocol uses what is known as a connection-based setup.
This creates a link between one computer to another. The information is sent between these two connections. On the same note, HTTP or Hypertext Transfer Protocol is an extension of this and works similarly.
In comparison, UDP or User Datagram Protocol has a connectionless setup.
This means it is not as reliable because it works from one program to another. If there are any drops within the programs, this can make the protocol ineffective.
However, due to how it is set up, it also works faster than the other protocols.
If reliability is important, most users will lean towards TCP.
2. Speed
The next most important metric would be speed.
Let’s assume a user is gaming and the protocol is being relied upon to offer a seamless transfer of information. In a case such as this, it does not make sense to use TCP.
Instead, it is better to use UDP.
The reason UDP works is that it is connectionless. The connection is not going to matter, which allows information to pass from one program to the other seamlessly.
It is common for UDP to be used for gaming or situations where small amounts of information are being passed quickly. This information can get to its destination faster through UDP.
3. Simplicity
When simplicity is the case, UDP tends to work with this in mind.
The packets that are being transferred are not going to be ordered. This means they are simply pushed from one program to the other through the connectionless setup.
In comparison, TCP is more robust because it offers an ordered solution.
All packets of information going from one computer to the other are going to be in the precise order they were sent. This is important in many scenarios such as video encoding.
This reliability is great but it is not as simple as UDP.
UDP works in a simple, effective manner. As the packets of information are pushed forward, they are sent to the other program.
4. Use Cases
Let’s take a look at use cases.
TCP is used for reliable, high-intensive solutions such as video encoding. The packets are passed through a connection-based setup from one computer to the other.
This makes it ideal for any process that requires strict consistency.
In comparison, UDP tends to work well for situations where fast processing is key such as gaming or answering small queries on a greater scale.
HTTP works mostly within an Internet browser such as Chrome or Safari. The information is tapped through a server that is passing out information to the user.
Final Thoughts
Look into these details when comparing TCP vs UDP vs HTTP.
TCP offers a more stable, consistent solution for processing information and is a connection-based protocol. HTTP uses a server-based connection and passes information through this solution which is commonly seen with Internet browsers. In comparison, UDP is a faster protocol and works with a connectionless solution commonly seen in gaming.
It’s best to look at the viability of each protocol to see how it works and how it is used.
For the most part, it is the use case that matters most with these protocols. This dictates the right setup.
