Computer Architecture

Computers are made up of:

• Input

• Procesing

• Output

• Storage Devices

Computer's main memory consists of:

• RAM and ROM

• CPU and Hard Disk Drive

• Magnetic and Optical Backing Storage Type

• CD-ROM and DVD-RW

Which of the following statements is true?

• RAM can only be read from and ROM can be read and re-written.

• ROM and RAM are the same in a modern computer.

• ROM can only be read from and RAM can be read and re-written.

• RAM keeps its contents when the computer is powered off or reset.

Any piece of hardware that takes real-world information and converts it into binary data is an input device.

• TRUE

• FALSE

What kind of device converts binary data back into real-world information?

• Input

• Output

• Memory

• Backing Storage

The computer's memory will hold an algorithm in the form of a program, which the processor will follow. By changing the program, you can change what the computer does.

What is the name for the concept above?

• Stored Program Concept

• Von Neumann Architecture

• High Level Language

• Translators

ALU stands for Arithmetic and Logic Unit.

• TRUE

• FALSE

What types of operations ALU is capable to perform?

• Comparison (>, <, =, ≠, ≥, ≤)

• Logical (AND, OR, NOT)

• Arithmetic (+, -, /, *)

• Binary Conversion to Denary (0, 1) ; (0,1,2,3,4,5,6,7,8,9)

Select correct statements.

The control unit is responsible for coordinating all the activities happening in the computer that require some of the processors time.

This includes:

• Fetching instructions and data from the main memory;

• The clock signal to keep actions in time with each other;

• Responding to peripherals sending/receiving data.

• Decoding instructions (sending them to the correct part of the processor)

Select correct statements.

Registers are temporary storage locations based on the processor chip. They will store items temporarily that the processor needs to complete operations.

Some examples of items that may be stored in the registers are:

• Results of calculations that have been carried out by the ALU;

• Data that will be needed by the ALU to perform a calculation;

• Addresses of data or instructions that will be needed next;

• The current instruction the processor is working on.
