Students should read Chapter 1

Hardware – Monitor, Keyboard, Mouse, CPU, Printer, Scanner

Software – Programs/Applications

Input Device – Keyboard, Microphone, Mouse, etc.

Output Device – Printer, Speakers, Monitor, etc.

Secondary Storage Device – Hard Drive, Floppy Disk, Zip Disk, etc.

Bit – Stores a Zero or a One (a binary digit)

Byte – Contains 8 bits and can store one character.

Before a Program runs it is transferred from a secondary storage device (the hard drive) to RAM (Random Access Memory). This memory will be erased if the computer is shut-off.

ROM (Read Only Memory) – Is used to store the startup instructions for the computer. It cannot be written to and is not erased when the power is shut off to the computer.

CPU (Central Processing Unit) – does all logical and mathematical calculations and runs the computer operations.

Operating System – Controls how the hardware and user interact.

Address – Where a memory location resides.

Compiler – Transforms a high level language to machine language.

Source Code/File – The program which you create in a high level language such as C.

Syntax – The rules of a high level language.

Running a Program

***************************************************************************

Let’s look at a C program and try to decipher the different commands and syntax used.

#include <stdio.h> /* this is the standard input/output library */

/*using the include statement above is like copying or typing the library functions used in your program into your program */

void main( ) /* define a function named main */

{

/* call the function printf to print sequence of characters.

The call to this function is made from main */

printf(“hello, world\n”);

}

A typical C program has preprocessor instructions 1^st then the main function and any other functions following main. Each function is made up of statements that may be any of the following: a declaration, assignment, function, control or null.
