In computing, a resident monitor is a type of system software program that was used in many early computers from the 1950s to 1970s. It can be considered a precursor to the operating system . [ 1 ] The name is derived from a program which is always present in the computer's memory, thus being resident . [ 2 ]
Microarchitecture, also known as computer organization, refers to high-level hardware questions such as the design of the CPU, memory, and memory interconnect. [26] Memory hierarchy ensures that the memory quicker to access (and more expensive) is located closer to the CPU, while slower, cheaper memory for large-volume storage is located ...
A system monitor displaying system resources usage. A system monitor is a hardware or software component used to monitor system resources and performance in a computer system. [1] Among the management issues regarding use of system monitoring tools are resource usage and privacy. Monitoring can track both input and output values and events of ...
This circuitry converts an in-memory bitmap into a video signal that can be displayed on a computer monitor. In computing , a screen buffer is a part of computer memory used by a computer application for the representation of the content to be shown on the computer display . [ 3 ]
On two-dimensional display devices such as computer monitors the display size or viewable image size is the actual amount of screen space that is available to display a picture, video or working space, without obstruction from the bezel or other aspects of the unit's design. The main measurements for display devices are width, height, total ...
CPU, both time on a single CPU and use of multiple CPUs – see multitasking; Random-access memory and virtual memory – see memory management; Hard disk drives, include space generally, contiguous free space (such as for swap space), and use of multiple physical devices ("spindles"), since using multiple devices allows parallelism

Although a full 16-bit processor, only the system ROM and 256 bytes of scratchpad RAM are available on the 16-bit bus. [ 6 ] Peripherals include a 5¼" floppy disk drive and controller, an RS-232 card with two serial ports and one parallel port, a P-code card for Pascal support, a thermal printer , a 300- baud acoustic coupler , a tape drive ...
