What Is A Motherboard?

Primary Circuit Connects all core components

Why A Motherboard Matters Allows components to communicate General-purpose and special-purpose

Who Has A Motherboard

Desktop PCs Notebook PCs Cell phones IPods Servers Supercomputers Outside devices to be connected to the

system components

Personal Computer Motherboard Sockets of microprocessor, main

memory, ROM, expansion slots Also includes buses

Different Size Motherboards Small ex. netbooks, tablets, or smart

phones Large ex. Alienware Area-51 ALX

What is A Bus?

Subsystem Transfers data

Why Does A Bus Matter?

Connects components of computer system

Speed of the Bus

Impact performance of a CPU

Front Side Bus

More commonly known as the FSB Considered the most important bus Connects the CPU to the northbridge

Other Bus’s

Internal Bus PCI Bus - Connects external devices to

the core system components through expansion slots, or USB or PCI connections.

LPC Bus - Connects ROM and sometimes other input devices to the CPU.

Machine Cycles

Definition

Machine Cycle - used as an orderly method of processing software instructions.

Why This Matters

Provides organized method for the processor to carry out instructions from the server.

Without the machine cycle the processor would not be able to execute software code.

Step 1

Fetch

Instructions are fetched from primary storage (RAM) or its cache memory.

Step 2

Decode

The control unit decodes the instruction and then sends it to the arithmetic logic

Step 3

Execute

The decoded instruction is sent to the ALU to execute.

Step 4

Store

The results of the instructions are stored back primary storage.

Machine Cycle Facts

Today’s processors can overlap machine cycles and even execute multiple instructions simultaneously.

Machine Cycle’s keep computers running smoothly, and processing orderly.
