40 Network Protocol Names And Port Numbers With Their Transport Protocols And Meanings tabulated by Precious Ocansey (HND, Network Engineer).
Before going straight to the table.
Firstly, what are Network Protocols?
Network protocols are the languages and rules used during communication in a computer network. There are two major transport protocols namely;
TCP and UDP
TCP which stands for “Transmission Control Protocol”, is a suite of communication protocols used to interconnect network devices on a local network or a public network like the internet. TCP is known as “connection-oriented” protocols as it ensures each data packet is delivered as requested. Therefore, TCP is used for transferring most types of data such as webpages and files over the Internet.
UDP which stands for “User Datagram Protocol” is part of the TCP/IP suite of protocols used for data transferring. UDP is a known as a “connectionless-oriented” protocol, meaning it doesn’t acknowledge that the packets being sent have been received. For this reason, the UDP protocol is typically used for streaming media. While you might see skips in video or hear some fuzz in audio clips, UDP transmission prevents the playback from stopping completely.
Furthermore, TCP also includes built-in error checking means TCP has more overhead and is therefore slower than UDP, it ensures accurate delivery of data between systems. Therefore TCP is used for transferring most types of data such as webpages and files over the local network or Internet. UDP is ideal for media streaming which does not require all packets to be delivered.
Port Numbers: They are the unique identifiers given to all protocol numbers so they can be accessed easily.
