A modern computer operating system usually uses virtual memory to provide separate address spaces or separate regions of a single address space, called user space and kernel space. [1] [a] Primarily, this separation serves to provide memory protection and hardware protection from malicious or errant software behaviour.
Without protected memory, it is possible that a bug in one program will alter the memory used by another program. This will cause that other program to run off of corrupted memory with unpredictable results. If the operating system's memory is corrupted, the entire computer system may crash and need to be rebooted. At times programs ...
The user could also adjust this figure using the Get Info dialog, typically to increase the amount of memory for programs with large needs, like Photoshop. Segmented virtual memory is a further generalization of this mechanism to a large number of segments. Usually the segment table is kept in memory rather than registers.
"Default User" - Plays a role in the profile-creation process, see above. "All Users" - This profile is present mainly to answer an issue related to software installation. It provides a way for setup programs to create desktop or start-menu shortcuts which will be visible to all users of the computer, not just the user running the setup program.
An 80×80×25 mm computer fan computer form factor The name used to denote the dimensions, power supply type, location of mounting holes, number of ports on the back panel, etc. control store The memory that stores the microcode of a CPU. Conventional Peripheral Component Interconnect (Conventional PCI) Also simply PCI.
Many game consoles use interchangeable ROM cartridges, allowing for one system to play multiple games. Shown here is the inside of a Pokémon Silver Game Boy cartridge. The ROM is the IC on the right labeled "MX23C1603-12A". Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices.
A 68451 MMU, which could be used with the Motorola 68010. A memory management unit (MMU), sometimes called paged memory management unit (PMMU), [1] is a computer hardware unit that examines all memory references on the memory bus, translating these requests, known as virtual memory addresses, into physical addresses in main memory.
For simplicity, main memory is called "RAM" (an acronym of random-access memory) and secondary storage is called "disk" (a shorthand for hard disk drive, drum memory or solid-state drive, etc.), but as with many aspects of computing, the concepts are independent of the technology used.
