Study Notes

The Motherboard

The motherboard is the main circuit board of a computer, attaching various electronic components such as the processor and memory.
Some components are attached to the motherboard, while others are built into it.

Integrated Circuits

A computer chip is a small piece of semiconducting material, usually silicon, containing integrated circuits.
Integrated circuits contain many microscopic pathways capable of carrying electrical current and can contain millions of elements such as resistors, capacitors, and transistors.
A transistor, a type of element, can act as an electronic switch that opens or closes the circuit for electrical charges.

Processors

The processor, also known as the central processing unit (CPU), interprets and carries out the basic instructions that operate a computer.
The processor significantly impacts overall computing power and manages most of a computer's operations.
On personal computers, all functions of the processor usually are on a single chip.

Multi-Core Processors

Most processor chip manufacturers now offer multi-core processors.
A multi-core processor is a single chip with two or more separate processor cores.
Each processor core on a multi-core processor generally runs at a slower speed than a single-core processor, but multi-core processors typically increase overall performance.
Multi-core processors are more energy efficient than separate multiple processors, requiring lower levels of power consumption and emitting less heat.

Processor Components

Processors contain a Control Unit and an Arithmetic Logic Unit (ALU).
The Control Unit interprets and executes instructions in memory, and the Arithmetic Logic Unit (ALU) performs calculations on the data in memory.
The Control Unit directs and coordinates most of the operations in the computer, interpreting each instruction issued by a program or an application and initiating the appropriate action to carry out the instruction.
The Arithmetic Logic Unit (ALU) performs arithmetic, comparison, and other operations.
