A server is a computer, equipped with specific programs and / or hardware, to enable it to offer services to other computers (clients) on its network (connected to it). Servers are other computers. There are different types and capabilities of servers. Think about transportation. We can think of transportation as anything that can move something or someone from one location to the other. A bicycle can move one person, a car can move 4 people, a bus can move 50 people and a plane can move 500 people. They are all modes of transport, but with different capacities. The same applies to servers.
