One of the key elements of a computer network is the protocols it uses. There are a variety of different protocols for the different functions and layers of a network. As you are probably aware, protocols include the instructions a device or segment of the network uses to move data. As a network engineer, you should be familiar with each protocol, recognize its acronym, know its full name, provide a brief description of what it does, and discuss which part of the network it applies to.

"TCP and UDP are network protocols built on the top of the internet protocol or IP.
TCP stands for Transmission Control Protocol, and UDP stands for Universal Datagram Protocol. Both are used to send bits of data or packets over the internet to an IP address. The difference between TCP and UDP is that TCP is slower but more reliable than UDP. In both protocols, transmission occurs sequentially. However, UDP does not maintain the same sequence when it reaches the destination. Also, while TCP tracks the data sent to ensure no data loss during data transmission, UDP does not."
