Frame Buffer-Chunk of RAM in w/c the computer
program stores the image in form of pixels
Display Hardware-produces image line by line Video Controller-H/W device that constantly reads
frame buffer and produces image on display

a high-end microcomputer designed for technical or
scientific applications.
Intended primarily to be used by one person at atime, they are commonly connected to a local area
network and run multi-user operating systems.
The term used to refer to a mainframe computer
terminal or a PC connected to a network. offered higher performance than desktop
computers,

computer hardware that generates computer graphics
and allows them to be shown on a display,
usually using a graphics card (video card) in
combination with a device driver to create the images
on the screen.
The most important piece of graphics hardware is
the graphics card(piece of equipment that renders out
all images and sends them to a display.)
graphics cards: integrated and dedicated
integrated graphics card: is bound to the motherboard
and shares RAM(Random Access Memory) with
the CPU, reducing the total amount of RAM available.

A dedicated graphics card :has its own RAM andProcessor for generating its images, and does notslow down the computer.
have higher performance than integrated graphics
cards
It is possible to have both dedicated and integratedgraphics, however once a dedicated graphics card isinstalled, the integrated card will no longer function
until the dedicated card is removed. Parts of a Graphics Card : The GPU or graphics
processing unit, is the unit that allows the graphicscard to function.

Video Memory is built in RAM installed on thevideo card that provides the graphics card with itsown RAM and allows it to run smoothly withouthaving to take resources from the computer
Display Drivers : A display driver is a piece ofsoftware which allows your graphics hardware tocommunicate with your operating system.
allow your computer to utilize parts of itself, and
without them, the machine would not function. a driver is required to translate between the two, and
convert general commands into specific commands,and vice versa.
