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

phones Large ex. Alienware Area-51 ALX

What is A Bus?
Subsystem Transfers data

Why Does A Bus Matter?
Connects components of computer system
![Page 10: Motherboard presentation it](https://reader033.fdocuments.in/reader033/viewer/2022060118/55892328d8b42a6e778b462a/html5/thumbnails/10.jpg)
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
![Page 14: Motherboard presentation it](https://reader033.fdocuments.in/reader033/viewer/2022060118/55892328d8b42a6e778b462a/html5/thumbnails/14.jpg)
Definition
Machine Cycle - used as an orderly method of processing software instructions.
![Page 15: Motherboard presentation it](https://reader033.fdocuments.in/reader033/viewer/2022060118/55892328d8b42a6e778b462a/html5/thumbnails/15.jpg)
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.
![Page 17: Motherboard presentation it](https://reader033.fdocuments.in/reader033/viewer/2022060118/55892328d8b42a6e778b462a/html5/thumbnails/17.jpg)
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.
