Study Notes
The Control Unit (CU)
- Responsible for directing the flow of data and instructions within a CPU.
- Acts as the "traffic cop" by coordinating various components to ensure smooth execution of instructions.
- Interprets and executes instructions coming from the system's main memory.
The CPU as the Brain
- Serves as the central processing unit, responsible for handling all the calculations and operations required for the computer to work.
- Processes data, executes instructions, and manages the overall operation of the computer system.
Arithmetic Logic Unit (ALU) Operations
- Performs arithmetic calculations (addition, subtraction, multiplication, division) and logical operations (comparison, AND, OR, NOT).
- Essential for processing data in a computer, enabling applications to perform complex computations.
Temporary Data Storage
- The CPU uses a cache to store frequently accessed data.
- Enables fast access to data, reducing the time it takes to process information.
Data Storage Component
- The hard drive (or other storage device) is responsible for storing data.
- It acts as the long-term memory of a computer, retaining data even when the computer is powered off.
