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 ]
A flat-panel display (FPD) computer monitor A cathode-ray tube (CRT) computer monitor. A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls.
16 KB of RAM is provided for the Video Display Processor. VDP RAM is the largest block of writeable memory in the unexpanded TI-99/4A architecture, and is used for storing disk I/O buffers and TI BASIC user programs. Access to this memory has to use the VDP as an intermediary.
With on-board 2D and 3D acceleration introduced in 1984 for the 8-bit PC-bus, intended for CAD applications, a triple-board display adapter with built-in processor, and displaying high-resolution, full-colour graphics at a 60 Hz frame rate.

A small and fast buffer memory between the CPU and the main memory. Reduces access time for frequently accessed items (instructions / operands). cache coherency The process of keeping data in multiple caches synchronised in a multiprocessor shared memory system, also required when DMA modifies the underlying memory. cache eviction
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 ]
Also in 1982 the Plantronics Colorplus board was introduced, with twice the memory of a standard CGA board (32k, compared to 16k). The additional memory can be used in graphics modes to double the color depth, giving two additional graphics modes—16 colors at 320 × 200 resolution, or 4 colors at 640 × 200 resolution.
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
