Difference between Operating system and Protected mode

Operating system vs. Protected mode

An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. In computing, protected mode, also called protected virtual address mode, is an operational mode of x86-compatible central processing units (CPUs).

Similarities between Operating system and Protected mode

Operating system and Protected mode have 28 things in common (in Unionpedia): Assembly language, Call stack, Central processing unit, Computer multitasking, Crash (computing), Device driver, Hard disk drive, IBM, IBM Personal Computer, Input/output, Intel 80286, Intel 80386, Linux, Memory segmentation, Microsoft Windows, MINIX, OS/2, Paging, Preemption (computing), Protection ring, Software, System software, Unix, Virtual memory, Windows 9x, Windows NT, X86, 32-bit.

Assembly language

An assembly (or assembler) language, often abbreviated asm, is a low-level programming language, in which there is a very strong (but often not one-to-one) correspondence between the assembly program statements and the architecture's machine code instructions.

Call stack

In computer science, a call stack is a stack data structure that stores information about the active subroutines of a computer program.

Central processing unit

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

Preemption (computing)

In computing, preemption is the act of temporarily interrupting a task being carried out by a computer system, without requiring its cooperation, and with the intention of resuming the task at a later time.

Protection ring

In computer science, hierarchical protection domains, often called protection rings, are mechanisms to protect data and functionality from faults (by improving fault tolerance) and malicious behaviour (by providing computer security).

Software

Computer software, or simply software, is a generic term that refers to a collection of data or computer instructions that tell the computer how to work, in contrast to the physical hardware from which the system is built, that actually performs the work.

Unix

Unix (trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.

Virtual memory

In computing, virtual memory (also virtual storage) is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" which "creates the illusion to users of a very large (main) memory." The computer's operating system, using a combination of hardware and software, maps memory addresses used by a program, called virtual addresses, into physical addresses in computer memory.
