FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -In 1965, IBM created the first graphic display machine. The IBM 1130 computer was used with the IBM 2250 display unit. The IBM 2250 was a cathode ray tube (blank screen TV), which used programmed software from the IBM 1130. The images were drawn on a screen using a light pen and displayed vector graphics.

Detailed explanation-2: -The first computer graphics design system was developed by Evan Sutherland as his PhD thesis at MIT in 1963. It was called Sketchpad and allowed a user to sketch a mechanical part on a computer screen, place constraints on the part, and have the computer calculate the exact design of the part.

Detailed explanation-3: -In 1987, the IBM 8514 graphics system was released as one of the first video cards for IBM PC compatibles to implement fixed-function 2D primitives in electronic hardware.

Detailed explanation-4: -The label “digital” is an attempt to label the graphic style which emerged in the 1990s as a result of the revolutionary changes in computer technology.

Detailed explanation-5: -The Video Graphics Array (VGA) standard was released in 1987, providing a video resolution of 640 x 480 with 16 colors and up to 256 KB of video memory. ATI introduced their first VGA video card, the ATI VGA Wonder. Some VGA Wonder cards even featured a mouse port for mouse connectivity.
