On operating systems without memory protection, this could be any process on the system.

Windows 3.1-Me had some level of memory protection, but programs could easily circumvent the need to use it.

In the same way as on a computer, memory protection prevents privilege escalation.

Simply adding memory protection to the existing system wouldn't work, because many applications expected to operate in an environment where it wasn't present.

It is designed to have virtual memory and memory protection when available.

Different operating systems use different forms of memory protection or separation.

On Unix-like systems, the mprotect system call is used to control memory protection.

Real mode provides no support for memory protection, multitasking, or code privilege levels.

Memory protection keeps one errant application from wildly crashing the entire computer.

Like other operating systems of the time, the OS lacks memory protection.

Some units also provide memory protection from misbehaving devices.

The trick is to find the equivalent of "memory protection and preemptive multitasking."

In addition, they implemented only partial memory protection.

To support multiprogramming, the 1108 had memory protection using two base and limit registers, with 512-word resolution.

The 980 was, for its time, a relatively powerful small computer that offered memory protection and multiple-priority interrupt capabilities.

Some operating systems that do implement memory protection include:

The differences between the different versions are slight, mostly owing to savegame memory protection behavior.

Memory protection enables the kernel to limit a process' access to the computer's memory.

There is no memory protection and the kernel is almost always running in a user mode.

Memory protection is a way to control memory access rights on a computer, and is a part of most modern operating systems.

Apple did actually add the ability for the kernel to use memory protection in OS9, but had to leave it disabled.

OSEK systems are expected to run on chips without memory protection.

The 286 architecture introduced protected mode, allowing for (among other things) hardware-level memory protection.

Various methods of memory protection exist, including memory segmentation and paging.

Although the usages were different, the segments did not have different memory protections reflecting this.
