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.
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
zram, formerly called compcache, is a Linux kernel module for creating a compressed block device in RAM, i.e. a RAM disk with on-the-fly disk compression. The block device created with zram can then be used for swap or as general-purpose RAM disk.
Available for Windows 7 to 11, or Windows Server from 2008 R2 to 2022; 32/64-bit x86 or 64-bit ARM. SoftPerfect RAM Disk can access memory available to Windows, i.e. on 32-bit systems it is limited to the same 4 GB as the 32-bit Windows itself, otherwise for physical memory beyond 4 GB it must be installed on 64-bit Windows.
Both hdparm and mdtrim find free blocks by allocating a large file on the filesystem and resolving what physical location it was assigned to. Regardless of operating system, the drive can detect when the computer writes all zeros to a block, and de-allocate (trim) that block instead of recording the block of zeros.
NOTE: Linux systems may vary by distribution which specific program, or even 'command' is called, via the POSIX alias function. For example, if you wanted to use the DOS dir to give you a directory listing with one detailed file listing per line you could use {{{1}}} (e.g. in a session configuration file).
A light-weight Linux distribution is a Linux distribution that uses lower memory and processor-speed requirements than a more "feature-rich" Linux distribution. The lower demands on hardware ideally result in a more responsive machine , and allow devices with fewer system resources (e.g. older or embedded hardware ) to be used productively.
Microsoft Windows has the tasklist command and the graphical Task Manager utility. IBM AIX has an updating running processes list as part of the topas and topas_nmon commands. The load average numbers in Linux refers to the sum of the number of processes waiting in the run-queue plus the number currently executing.
