Extended memory is located above 1 MB, includes the high memory area, and ends at 16 MB on the Intel 286 and at 4 GB on the Intel 386DX and later.. In DOS memory management, extended memory refers to memory above the first megabyte (2 20 bytes) of address space in an IBM PC or compatible with an 80286 or later processor.
RAM drives use normal system memory as if it were a partition on a physical hard drive rather than accessing the data bus normally used for secondary storage. Though RAM drives can often be supported directly in the operating system via special mechanisms in the OS kernel, it is generally simpler to access a RAM drive through a virtual device ...
Secure deletion of free space or disk using a "zero out" data, a 7-pass DOD 5220-22 M standard, or a 35-pass Gutmann algorithm; Adding or changing partition table between Apple Partition Map, GUID Partition Table, and master boot record (MBR) Restoring volumes from Apple Software Restore (ASR) images; Checking the S.M.A.R.T. status of a hard disk
Software can "partition" a portion of a computer's RAM, allowing it to act as a much faster hard drive that is called a RAM disk. A RAM disk loses the stored data when the computer is shut down, unless memory is arranged to have a standby battery source, or changes to the RAM disk are written out to a nonvolatile disk. The RAM disk is reloaded ...
Each controller is 16-bits wide and is capable of accessing up to 4 GiB of memory. [14] The M3 Pro and 14-core M3 Max have lower memory bandwidth than the M1/M2 Pro and M1/M2 Max respectively. The M3 Pro has a 192-bit memory bus where the M1 and M2 Pro had a 256-bit bus, resulting in only 150 GB/sec bandwidth versus 200 GB/sec for its predecessors.
Virtual memory combines active RAM and inactive memory on DASD [a] to form a large range of contiguous addresses.. In computing, virtual memory, or virtual storage, [b] is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" [3] which "creates the illusion to users of a very large (main) memory".
Space Gremlin is designed to find large and unnecessary files to delete on a hard drive. [2] It uses a squarified treemap algorithm [3] to display the relative sizes of files and folders. It allows the user to zoom in and out of folder structures and mask out parts of the file system by toggling hidden or 'Ignored' files.
Mac gaming refers to the use of video games on Macintosh personal computers. In the 1990s, Apple computers did not attract the same level of video game development as Microsoft Windows computers due to the high popularity of Windows and, for 3D gaming, Microsoft's DirectX technology.
