Operating system (OS) is the software part of a computer that manages memory, processes, and hardware. The OS serves for the stable functioning of the computer and without it, the use of the hardware component is not possible.

Step 1
Operating systems come in several flavors. Today, the most common type is multi-user, shared systems. They allow multiple users to access a computer at the same time using a graphical shell, terminal, or using a network console. Among the most popular operating systems are the Windows and Unix families.
Step 2
Single-user systems differ in that they have the ability to operate only one user. They do not have the above properties of multi-user systems and at the moment can be considered obsolete. A prime example of such operating systems were MS DOS and OS / 2.
Step 3
A network operating system has a specific structure and is used on server computers to support the operation of computer networks. Examples of server operating systems are Windows Server, Linux, FreeBSD and many others that differ in their characteristics and features.
Step 4
Also, OS can be classified according to certain parameters. For example, depending on the availability of a graphical shell, there are graphical and text systems. You can also distinguish paid and free OS, open and closed (depending on the ability to edit the source code of the program), client and server, simple and difficult to administer. Also, systems are classified by bitness: 32 or 64-bit OS.
