what is a server and what does it do. Does it help with work

servers are typically used to provide common file storage and access to multiple computers on a network, to control access to computers on a network via passwords, etc.

In my case, A server is used to restrict access to 10 networked computers, via logon name and password, so that only those authorized can use the workstations. At any time, we typically have 150 to 200 people so authorized. The main server also is a file server that permits each authorized user to have their individual storage space, which they can accesss from any workstation on the local network.

We also have print servers so that a user can direct output to any particular monochrome laser or color inkjet printer on the network.

Although we do not handle Internet traffic through the server, this can be done in a manner similar to mail service mentioned by Kees.

As you can see, servers have no real function except in connection with networks that, because of size, complexity, and/or number of users, are not suited to peer-to-peer networking.
