epoll is a Linux kernel system call for a scalable I/O event notification mechanism, first introduced in version 2.5.45 of the Linux kernel. [1] Its function is to monitor multiple file descriptors to see whether I/O is possible on any of them.
Similar displays in the Task Manager of Windows Vista and later have been changed to reflect usage of physical memory. In Task Manager's "Processes" display, each process's contribution to the "total commit charge" is shown in the "VM size" column in Windows XP and Server 2003. The same value is labeled "Commit size" in Windows Vista and later ...
In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations [1] in a way that memory which is no longer needed is not released. A memory leak may also happen when an object is stored in memory but cannot be accessed by the running code (i.e. unreachable memory). [2]
An idle computer has a load number of 0 (the idle process is not counted). Each process using or waiting for CPU (the ready queue or run queue) increments the load number by 1. Each process that terminates decrements it by 1. Most UNIX systems count only processes in the running (on CPU) or runnable (waiting for CPU) states.
Some of the first 100 MHz DX chips had a buggy HLT state, prompting the developers of Linux to implement a "no-hlt" option for use when running on those chips, [4] but this was fixed in later chips. Intel has since introduced additional processor-yielding instructions. These include: PAUSE in SSE2 intended for spin loops. Available to userspace ...
Tiny Core Linux is an example of Linux distribution that run from RAM. This is a list of Linux distributions that can be run entirely from a computer's RAM, meaning that once the OS has been loaded to the RAM, the media it was loaded from can be completely removed, and the distribution will run the PC through the RAM only.

The Management Engine is often confused with Intel AMT (Intel Active Management Technology). AMT runs on the ME, but is only available on processors with vPro.AMT gives device owners remote administration of their computer, [5] such as powering it on or off, and reinstalling the operating system.
