Introduction Whats a Computer?
An electronic device:
Gets Input Processes the Input Output
Why Use a Computer?
Time Accuracy Reliability
You type an MS_Word document (Input) You click on the Print button (Process) The document is printe
Chap_2 => Main Memory => Stores information (to be used by the CPU) temporarily. A need for a permanent storage => Secondary Storage Mainly:
Hard Disk Floppy Disk External Storage (Tapes, Cartridges, )
Why organize Data?
To easily f
Describe the basic components of a network Explain the methods of data transmission Differentiate among the various kinds of communications channels Describe the different types of computer networks Describe different Internet applications
The Boolean Data Type
This data type allows us to represent something as either True or False. Syntax:
Const flag = True; Var Variable_Name : Boolean
Var Flag: Boolean Flag := True Writeln(Flag) (* will give as output True *)
Repetition Statements Loops
In the programs studied so far a statement is executed only once. Sometimes a process can be repeated many times: repetition The repetition of steps in a program is called Loop Pascal has three loop control statements: While F
Input and Output
Read, and Readln
The following statement: Writeln(123) will give as output the following:
123 The number is printed using 3 spaces
Write, and Writeln
Unless specified Pascal uses fixed width output
Computers: Hardware, and Software Software: Set of Programs made of Instructions An instruction is a simple elementary Task to be performed by the computer Example of instructions: Read an input from the keyboard. Display something o
