What do you need to know about TCP and UDP?
TCP and UDP Explained TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are responsible for transporting data packets to the designated address. As such, TCP and UDP correspond to the Transport Model in the OSI model layers. The way they differ is in their approach to how they deliver the data packets.

What’s the difference between UDP and Transmission Control Protocol?
It is because it provides flow control and acknowledgement of data. UDP has only the basic error checking mechanism using checksums. Sequencing of data is a feature of Transmission Control Protocol (TCP). this means that packets arrive in-order at the receiver. There is no sequencing of data in UDP.
What’s the difference between TCP and IP protocols?
TCP/IP is a suite of protocols used by devices to communicate over the Internet and most local networks. It is named after two of it’s original protocols—the Transmission Control Protocol (TCP) and the Internet Protocol (IP). TCP provides apps a way to deliver…
