This document discusses C programming and computer graphics. It covers hardware components like display devices (CRT, LCD), input devices (keyboard, mouse, trackball, joystick), and output devices (dot matrix printer, laser printer, plotter). It also discusses algorithms, flowcharts, and different control structures in programming like sequence, selection, and repetition. Flowcharts are used to document the program logic and algorithm. Examples of algorithms and flowcharts for problems like finding the largest of three numbers are included.

3. Display Devices
A Display Device is an Output device for presentation of Information
for Visual reception.
The Display Systems are often referred to as Video Monitor or Video
Display Unit (VDU).

26. Algorithm & Flowchart
A sequence of instructions is called an Algorithm.
Algorithms are a fundamental part of computing.
There are two commonly used tools to help to document program logic
(the algorithm).
These are Flowcharts and Pseudocode.
