Pc based os

Actually windows too have multi user server edition that means you can use windows server in LAN environment serving different client PC's as a file server, internet server, database server. For WEB server there are better staffs.Unix is more used in scientific lab servers. So all servers are muti user but all muti users must not be unix servers. Hope this is ok.

Hello Friends,

An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system. Application programs usually require an operating system to function. As computers have progressed and developed so have the operating systems. Below is a basic list of the different operating systems and a few examples of operating systems that fall into each of the categories. Many computer operating systems will fall into more than one of the below categories.
1. GUI
2. Multi-user
3. Multiprocessing
4. Multitasking
