Computer
A computer is a programmable, multiuse machine
that accepts data, ( raw facts and figures ) and
process ,or manipulates, it into information.

Information:
“processed data
information”

on

a

computer

is

called

11
Parts of the Computer System
• Building Blocks of computer system
– Data (information)
– User
– Hardware
– Software

CSC141 Introduction to Computer

12
Parts of the Computer System
• Data
– Pieces of facts
– Computer organize and present information
• Users
– People operating the computer
– Computer working for the people
– Users are most important part of the
computers
– Tell the computer what to do

15
HARDWARE:
INPUT DEVICES
These devices allow the user to enter the data into
the computer.
These devices are;
• Keyboard
• Mouse
• Scanner
• Pointer

CSC141 Introduction to Computer

16
HARDWARE:
OUTPUT DEVICES
Consist of devices that translate information
processed by the computer into human
understandable format.
These devices are:
• Printer
• Monitor
• Speaker

the
Control
unit
called
Commands that a CPU can
execute

HARDWARE:
MEMORY

Two categories of Memory
• Volatile Memory
Loses its contents when the computer's
power is turned off
• Non-volatile Memory
Does not lose its contents when the
computer’s power is turned off

CSC141 Introduction to Computer
Programming

22
HARDWARE:
MEMORY
Stores Data or programs
(workspace or archiving/storage space)
RAM: Random Access Memory (Volatile)
• Stores current Data and programs
• More RAM results in a faster system

ROM: Read Only Memory (non-volatile)
• Permanent storage of programs/instructions
• Holds the computer boot directions

HARDWARE:
Memory; CPU Registers (Part of ALU)

• High speed memory locations built directly
into the CPU
• Temporary storage location used by the
CPU (Scratchpad)
• Used to hold data currently being
processed
• Results of the calculations
• Very expensive that’s why very limited.

Programming

25
TYPES OF SOFTWARE
SYSTEM SOFTWARE
Enables the application to interact with the computer
and manages the computer internal resources.
Examples:
– Operating System
– Device Drivers
APPLICATION SOFTWARE
It performs useful work on General-purpose task.
Examples:
– MS-Word
– PowerPoint
– Google (search engine)
CSC141 Introduction to Computer
Programming

26
Utility Programs
• Utility Programs provide services not provided
by the system software.
• Usually used to recover the system, data or
resources.
• Examples:

– Data recovery
– Backup
– Virus protection
– Norton utilities

27
How CPU works?
Four basic operations:
1. Fetch: obtain a program instruction or data
item from memory.

2. Decode: translate the instruction into
commands.
3. Execute: carry out the command.
4. Store: write the result into the memory
CSC141 Introduction to Computer
Programming

28
Machine Cycle
A Machine Cycle comprises i-time and e-time:
• Instruction time or i–time
to fetch and decode
• Execution time or e–time
to execute and store the
result

CSC141 Introduction to Computer
Programming

29
How CPU Synchronizes?
Through System Clock
System Clock Synchronizes all computer operations
• Train of binary pulses
• Faster clock speed means the CPU can
execute more instructions each second
• Units: MHz and GHz
Hz = cycles per second
