Answer:
Port a number used within a computer to identify a specific process.
IP Address a numerical reference to a particular device in a network.
Server a computer that handles requests and returns data to other computers in a network.
Step-by-step explanation:
A port number is a number used to uniquely identify a particular process, application or program on a computer. From the networking parlance, it is a logical address that uniquely identifies a process, protocol or application communicating with other process, protocol or application over a network. For example;
i. a file transfer protocol (FTP) could use a port number of 20 or 21.
ii. a simple mail transfer protocol (SMTP) could use a port number of 25
Internet Protocol (IP) address is a numerical reference or label assigned to a particular device in a network which helps to uniquely identify the device on the network. IP addresses (version 4) are expressed as a group of four numbers separated by a dot. For example, an IP address may look like this: 192.168.0.90
A server is a computer that receives requests from other computers, processes these requests and returns some data to the other computers in a network. In reality, these servers and the computers they serve can actually be some applications or programs. Servers provide resources, data, services or programs to other computers over a network.
