What are the basic tasks of the operating system?

Operating system performs the following functions:

Booting: Booting is a process of starting the computer operating system starts the computer to work.

Memory Management.

Loading and Execution.

Data security.

Disk Management.

Process Management.

Device Controlling.

Printing controlling.

An “Operating System” (OS) is system software that manages computer hardware and software resources and provides common services for “Application Software”. Application Software usually require an operating system to function. The relationship between OS and Application Software is clearly shown in the picture above.

An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it.

Examples of network operating systems include Microsoft Windows Server 2003, Microsoft Windows Server 2008, UNIX, Linux, Mac OS X, Novell NetWare, and BSD. Upgrades to new technologies and hardware can be easily integrated into the system.

A process, in the simplest terms, is an executing program. One or more threads run in the context of the process. A thread is the basic unit to which the operating system allocates processor time. A thread can execute any part of the process code, including parts currently being executed by another thread.

Features of an Operating system are:

Hardware Interdependence.

Provides User Interface.

Hardware Adaptability.

Memory Management.

Task Management.

Betworking Capability.

Logical Access Security.

File Management.

Booting is a startup sequence that starts the operating system of a computer when it is turned on. A boot sequence is the initial set of operations that the computer performs when it is switched on. Every computer has a boot sequence.

A graphical user interface (GUI) is a human-computer interface (i.e., a way for humans to interact with computers) that uses windows, icons and menus and which can be manipulated by a mouse (and often to a limited extent by a keyboard as well). Icons are used both on the desktop and within application programs.

Different types of operating systems are:

Character user interface (CUI)-based operating systems.

Graphical user interface (GUI)-based operating systems.

Single-user operating systems.

Multi-user operating systems.

Single-tasking operating systems.

Multitasking operating systems.

Real-time operating systems.

An operating system (OS) is system softwarethat manages computer hardware and software resources and provides common services for computer programs. All computer programs, excluding firmware, require an operating system to function.

Examples of Operating Systems. Some examples include versions of Microsoft Windows (like Windows 10, Windows 8, Windows 7, Windows Vista, and Windows XP), Apple’s macOS (formerly OS X), iOS, Chrome OS, BlackBerry Tablet OS, and flavors of the open source operating system Linux.

So here, in no particular order, are 10 different features I love in 10 different OSes.

Mac OS X, Time Machine.

Unix, The Shell Terminal.

Ubuntu, Simplified Linux Setup.

BeOS, 64-Bit Journaling File System.

IRIX, SGI Dogfight.

NeXTSTEP, Right-Click Context Menu.

MS-DOS, BASIC.

Windows 3.0, Alt-Tab Task Switching.

The term DOS can refer to any operating system, but it is most often used as a shorthand for MS-DOS (Microsoft disk operating system). Originally developed by Microsoft for IBM, MS-DOS was the standard operating system for IBM-compatible personal computers. Even Windows 95 sat on top of DOS.

OS just means “one size” as in one size fits most. These fit adults and older kids just fine.

Windows 10 (codenamed Redstone, formerly Threshold) is a personal computer operating system developed and released by Microsoft, as part of the Windows NT family of operating systems. It was released on July 29, 2015. It is the first version of Windows that receives ongoing feature updates.

Computer hardware is the collection of physical parts of a computer system. This includes the computer case, monitor, keyboard, and mouse. It also includes all the parts inside the computer case, such as the hard disk drive, motherboard, video card, and many others. Computer hardware is what you can physically touch.

Windows OS, computer operating system (OS) developed by Microsoft Corporation to run personal computers (PCs). Featuring the first graphical user interface (GUI) for IBM-compatible PCs, the Windows OS soon dominated the PC market. Approximately 90 percent of PCs run some version of Windows.

OS is an abbreviation for the word Operating System. An Operating System is the software that tells a computer how to operate. It controls hardware, executes programs, manages tasks and resources, and provides the user with an interface to the computer.

Memory management is the functionality of an operating system which handles or manages primary memory and moves processes back and forth between main memory and disk during execution. Memory management keeps track of each and every memory location, regardless of either it is allocated to some process or it is free.
