What Is A Computer ?

• A system or device capable of performing computations and making logical decisions at speeds in excess of billions per second.

• Computers process data under the control of sets of instructions called computer programs--those who write the programs are computer programmers.

• The various devices comprise the hardware.• The collection of programs is the software.• What is firmware?

Simplified Computer Organization

Computer can be divided into six logical units:

• Input unit -- the "receiving" section• Output unit -- the "shipping" department• Memory unit -- like a stockroom in a store• Arithmetic & logic unit -- like "manufacturing"• Central processing unit -- "management"– Note: The ALU is often considered part of the

CPU• Secondary storage -- high capacity warehouse

Finding A Solution To Problems

• The solution to a problem involves executing a series of actions in a specific order.

• The procedure for solving a problem expressed in terms of:

1. The actions to be executed, and

2. The order in which they are to be executed

Is called an algorithm.

Lect 1 P. 25



Control Structures

CONTROL STRUCTURES FOR THE ORDER OF EXECUTION ARE:

• SEQUENCE• SELECTION• REPETITION• ABSTRACTION

Lect 1 P. 26



Part Of The “Art” Of Programming

“The most important thing in life is showing up.”

Woody Allen

“The most important thing in computer programming is SYNTAX.”

Mike Miller

“Programming is NOT a spectator sport. To become good you must practice - practice - practice.”
