Study Notes
Power Supply
- Converts alternating current from the outlet to direct current for the computer's hardware components
- Consists of a transformer, voltage control, and fan
Motherboard
- Central circuit board that provides electrical connections for system components to communicate
- Has many ports and slots for connecting peripheral components
- May have built-in components such as CPU, graphics cards, RAM, and hard drive
Central Processing Unit (CPU)
- Executes computer programs using a four-step process: fetch, decode, execute, and writeback
- Retrieves program instructions from memory, breaks them down, executes them, and outputs results
- Continually repeats the fetch-execute cycle when turned on
Fetch-Execute Cycle
- The basic operation of a computer
- Involves:
- Fetch: retrieving an instruction from computer memory
- Decode: breaking down instructions and dispersing them throughout the CPU
- Execute: performing the desired operation using the broken-down instructions
- Writeback: outputting the results of the executed instructions
