The Main Operating System Of The Computer Use

The Main Operating System Of The Computer Use - The main operating system of the computer use

The operating system generally consists of several parts:

1. Boot Mechanism i.e. put the kernel into memory

2. The Kernel, i.e., the core of an operating system

3. Command Interpreter or shell, which is in charge of reading the input from the user

4. Library-Library provides a batch of basic functions and standards that can be called by other applications

5. Drivers for interacting with external hardware, as well as to control their

Most operating systems allow only one application running at a time (e.g. DOS), but most new operating Systems allow multiple applications running simultaneously at the same time.

Operating systems such as these are referred to as Multi-tasking Operating System (for example, UNIX family). Some S-sized Operations system is huge and complex, as well as the input depends on user input, whereas other operating systems is very small and is made assuming it works without human intervention at all. The first type is often referred to as a Desktop OS, while the second type is the real-time OS operating system currently

The main operating system used a computer system (including PCs, personal computers) is divided into three large groups:

1. Microsoft Windows Family – which among others consists of Windows Desktop Environment (version 1.x to version 3. x), Windows 9 x (Windows 95, 98, and Windows ME), and Windows NT (Windows NT 3.x, Windows NT 4.0,

Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows 7 (Seven), released in 2009, and Windows the Orient will be released in 2014)).

2. Unix Family that uses the POSIX operating system interfaces, such as SCO UNIX, BSD family (Berkeley Software Distribution), GNU/Linux, MacOS/X (based on the BSD kernel is modified, and known by the name Darwin) and GNU/Hurd.

3. Mac OS is an operating system for Apple computers called Mac or Macintosh. The latest operating system is Mac OS X version 10.4 (Tiger). Early in 2007 the planned launch of version 10.5 (Leopard). While Mainframe computers, Supercomputers and use lots of different operating systems, generally, is a derivative of the UNIX operating system developed by vendors such as IBM AIX, HP/UX, etc.
