Study Notes

Introduction to the System Unit

Microcomputer power is determined by speed, capacity, and flexibility.
Understanding a computer's performance is crucial for informed purchasing and compatibility with new applications.
Basic knowledge of microcomputer assembly is essential for competent end users.

System Board Components

Microprocessor:
- Central Processing Unit (CPU) acts as the brain of the computer.
- Contains two basic components: control unit and arithmetic-logic unit (ALU).
Sockets:
- Serve as connection points for chips on the motherboard.
Chips:
- Tiny circuit boards made of silicon known as semiconductor or integrated circuits.
- Functions like small brains, supporting the computer's operation.

Specialty Processors

Coprocessors:
- Enhance specific computing tasks, such as graphics through Graphics Processing Unit (GPU).
Smart Cards:
- Embedded chips in credit cards for secure transactions.
Specialty Processors in Vehicles:
- Used in cars to manage various functions.
RFID Tags:
- Information chips embedded in products to track locations.

Memory Types

RAM (Random Access Memory):
- Temporary storage for data, instructions, and information.
ROM (Read Only Memory):
- Permanent storage used to hold firmware.
Flash Memory:
- A type of non-volatile memory that can be electrically erased and reprogrammed.

Standard and Specialized Ports

Standard Ports:
- VGA and DVI: For connecting analog/digital monitors.
