Study Notes

Motherboard

Large circuit board with microchips and numerous sockets for connecting components.
Central communication hub for the computer, acting as a spinal cord connecting the brain (CPU) to other parts.
Connects CPU, GPU, hard drive, RAM, and other devices.
Must match the number of connected components to facilitate proper communication.
The CPU, GPU, and hard drive each communicate with the motherboard; the hard drive communicates with the RAM through the motherboard.

CPU (Central Processing Unit)

Small circuit board with a microchip.
Performs math and logic calculations, acting as the "brain" of the computer.
Must be compatible with the motherboard socket.
May have a metal protector covering the microchip.
Connector pins and dots are visible on the backside of the microchip.

RAM (Random Access Memory)

Small rectangular circuit board with microchips covered by a metal protector.
Metal connector pads are present on one side of the board.
Stores data for currently running programs and actively utilized applications.
Data is released when programs finish execution, making space for new programs.
Fast but with limited storage capacity.
Acts as short-term memory.
Must be compatible with RAM slots on the motherboard and sufficient to handle desired application needs.

Cooling

Crucial for preventing overheating and computer malfunctions.
Systems include fans, water cooling, air conditioning, and heat sinks.
Prevents computer components from overheating and causing damage or errors.
Heat sinks remove heat; fans dissipate heat to the surrounding air; water cooling diverts heat using water.
Similar to human sweating, which regulates body temperature.

GPU (Graphics Card)

Processes data from RAM to create images using calculations for color, shape, and 3D math.
Outputs video signals.
Connects to the motherboard via PCI Express x16 slot (PCIe x16) or may be integrated into the motherboard/CPU.
Output to RAM.

Monitor

Receives video signals from the GPU.
Converts signals into visual displays (colors and shapes) on the screen.
Connects to the GPU using HDMI, USB-C, or DisplayPort.
Output to RAM.

Keyboard/Mouse

Converts human input (keystrokes and clicks) into data (character and coordinates).
Input devices.
Connects via USB or wirelessly (USB dongle, Bluetooth).
Input to RAM.

Sound Card (SPU)

Processes data from RAM to produce audio signals.
Converts audio signals to digital data then stores it in RAM.
Connects via PCI Express x1, USB, or integrated into motherboards.
Can be an input and output device.
Output to RAM.

Speakers/Headsets

Produces sound waves from audio signals received from the SPU.
Connects to the SPU using a headphone/line-out jack.
Output to RAM.

Network Card (NIC)

Transfers data between the network and the computer.
Connects via PCIe x1, USB, or integrated into motherboards.
Can function as an input or output device.
