الحل


1. List the 4 factors that affect the computer power
- the microprocessor chip.
- The clock speed.
- The word size.
- The RAM.

2. Define the CPU, and mention its two main components

CPU: a chip inside the computer that processes data and controls the flow of data between the computer’s other units.
The two main components:
- The Arithmetic Logic Unit (ALU)
- Control Unit
- Buses


3- State briefly the difference between RAM, ROM, and hard disk. Which one of them is called ‘main memory’?


ROM is used extensively to program operation of computers and it holds the instructions for performing the power-on self test (POST) routine and the BIOS (basic input/output system) information used to describe the system configuration. For more detailed information" Motherboard and ROM BIOS."

4. What are the three main tasks of the microprocessor?

a. Read and write to computer’s memory
b. Manipulate information
c. Communicate with other parts of the computer

5. State briefly Moore’s Law.
- Number of transistors that can be placed on the same area of a microprocessor doubles every eighteen months


7. Define Turing machine. Who is its inventor?
- It was a general purpose mechanical device, outlined in a paper
- Receives basic instructions from a tape stream
- Proved that not all mathematical problems can be solved!
- It was the basis of computers
Designed by Alan Turing





8. State briefly what is Microsoft and what was its mission?
Microsoft is computer company
Established by:
w
Bill Gates & Paul Allen
- Microsoft mission was: “A computer on every desk in every house, running Microsoft software”

9. Define the Bootstrap. Where does it locate?
Bootstrap is a small program Loads the essential features of the operating system.
It locate in ROM

10. What is CP/M? Who is its inventor? And what is its relation to DOS? A brief

answer is required.
- CP/M is the first operating system for PC .
-Invented by Gary Kildall.
-The predecessor to DOS.

11. What does BIOS stands for and what is its role?

- Stand for (Basic Input/Output System)
- Interacts with various input and output devices of the computer that is using CP/M.


12-List briefly the advantages and disadvantage of GUI operating systems (no more than 3 points for both), and mention two examples of it.


advantages :
1- ease to use
2- compiled commands in tools
3- easy to learned
disadvantages:
1- hides a lot of operations
2-slow then commands-based
3-your control in computer be weak
Example:



13.List 3 inventions done in Xerox PARC
- GUI (Graphical User Interface).
- Ethernet (networking protocol).
- Object oriented programming (programming paradigm).
- The laser printer.

14.Define briefly the bit-mapping technique

the bit-mapping technique is Divides the screen (any image) to thousands of tiny picture elements (pixels), and specify a value for each

15.List three advantages of using networks over standalone computers

- Sharing resources.
- Communication.
- File access

16.List three networking topologies

Star topology .
Ring topology
Bus topology

17.Define WAN and mention an example of it

.WAN (Wide Area Network)
- Covers a large geographical area
- Each node maybe located in a different town
- Example: a multi-branch banking network

n The components that made up the PC bought from outside suppliers(not the manufacturer company itself).
Their design was freely available to anyone else.
example of it: IBM PC


20.Define IBM clones.

IBM clones : Computers which are
identical to the IBM PC in every important respect .


21.Define the reverse engineering process.
reverse engineering process: trying to copy the BIOS of IBM without breaking any copyright laws


22.List briefly some of the factors of a product’s success.a. Technological superiority .
b. Legacy
c. Market leader
d. Society acceptance
e. Product decisions
f. Markting
