With the development of the Internet, communications are being improved. Typically, data transfer is carried out using computer networks that are organized according to OSI standards. Interaction is possible on seven three levels of Media (3) and Host (4). TCP v.s. UDP relates to the second. These are transport layer protocols.
Below we will analyze their characteristic features, scope, and differences.
TCP protocol features
It is designed to transmit voluminous information. The reliability of the connection is guaranteed by a three-stage communication procedure. The request for the ISN and port value is sent to both the server and the client. The correctness of the data transmission is detected by the checksum. It is present in the package.
UDP protocol features
It is considered less reliable than TCP, but faster. The protocol is used for:
In these cases, the accelerated transmission of information is required. UDP is faster than TCP because you can reset lost datagrams and do not:
Remove batch duplicates;
Perform an initial connection test;
Observe the integrity of the structure.
Differences between TCP and UDP
The difference between TCP and UDP is clearly shown in the table:
Establishing a connection
Boundaries of transmitted datagrams
Not saved, but their integrity is guaranteed
Segmentation and assembly of packages
Scope of TCP and UDP usability
The TCP protocol is used for correspondence between users, sending photos, etc. It is preferable to UDP if the transmission of information must be accurate and validated.
UDP is more beneficial for voice and / or video streaming. Because it works faster.
As you can see, both protocols have advantages and disadvantages. Therefore, both TCP and UDP are used to transmit information. One protocol is simpler and faster, the other is more reliable. Based on the specific situation, it is necessary to choose the optimal protocol for communication.
