MOTHERBOARD

• Basic and fundamental component of any computer system

• It can be also called system board or main board
• Have bigger physical dimensions of hundreds of millimeters

motherboard

• connects all the other components
• Allow devices to communicate each other
• House the CPU

funtionmotherboard

• Refers to the physical size and shape of a computer device
• Important for connect ion compatibility.
• Often used to describe the size of circuit boards
• Have bigger physical dimensions of hundreds of millimeters

Central Processing Unit(cpu)

Start

CPU

Function

• Perform calculati onand carry all the instruction to computer

CPU speed is measured in

• Megahertz (MHz) - millions of CPU cycles per second
• also call CPU bus or the front side bus (FSB)

known as the brain of the computer Referred as the processor/microprocessor

Basic Operation of ALU

• Do the calculate and data comparison based on instructions from control unit.
• Arithmetic : mathematical operation (+,-,*,/).
• Logic: comparison operation (= , < , > , <>, <= and >= ).

Four Basic Operation of CU

• Fetch
• Decode
• Execute
• Store

perform arithmetic and logical operations

controls the flow of information through the processor, and coordinates the activities of the other units

EXAMPLE

EXAMPLE

AMD

AMD's desktop processors include Sempron, Athlon, and Phenom.

Intel's desktop CPUs include Celeron, Pentium, and Core

Intel

Various Types of Processor

• Refers to the physical size and shape of a computer device
• Important for connect ion compatibility.
• Often used to describe the size of circuit boards
• Have bigger physical dimensions of hundreds of millimeters

FORM FUNCTION

EXAMPLES

• dual-core processor with 2 cores

- e.g. AMD Phenom II X2, Intel Core 2 Duo E8500

• triple-core with 3 cores

- e.g. AMD Triple-Core CPU Phenom X3

• quad-core processor with 4 cores

- e.g. AMD Phenom II X4, Intel Core i5 2500T

- A single computing component comprised of two or more - It called cores - can run instructions on separate cores at the same time

MULTICORE PROCESSOR

- The wider the processor data bus width, the more powerful the processor is

- amount of data that a CPU can process at one time depends on the size of the processor data bus

- Overclocking used to make a processor work at a faster speed than original

- To operating system, a single CPU with hyper-threading appears to be two CPUs

Two major CPU architectures related to instruction sets: - Reduced Instruction Set Computer (RISC) - Complex Instruction Set Computer (CISC)

- The remain instructions and the data are stored in a special memory called cache

- CPU executes the program by process each piece of data directly by the program and instruction set

- Each model processor has an instruction set, which it executes

Versus

-can support memory amounts over 4 GB

- computers support a maximum of 3-4GB of memory

- delivers better graphics performance

- newer, faster, and more secure.

- older, slower, and less secure

64-bit processors

32-bit processors

• two main categories of processors are 32-bit and 64-bit
• Type of processor a computer has not only affects overall performance, but it can also dictate what type of software it uses.
• The Operating System and software on a computer with a 32-bit processor is also 32-bit based

32-bit Versus 64-bit Processing

1. Heat sink cooling 2. Case Fan Cooling

System cooling components

- A fan on top of the heat sink moves the heat away from the CPU. - Fans can be dedicated to cool the Graphics-processing unit (GPU).

- Electronic components generate heat. - A case fan makes the cooling process more efficient.

Cooling System:-

• To keep these components within their safe operating temperatures
• To keep the heat at a safe level.

Importance of computer cooling:-

- a device to dissipate heat during computer operation that usually install onto CPU, chipset, graphic card and hard drive / hard disk.
