Describe the input and output interfaces of microprocessors and microcontrollers.
DefinitionDescription should include
- internal microprocessor components (e.g., registers, arithmetic logic unit [ALU], central processing unit [CPU], co-processors, processor bus, primary cache memory, clock)
- external microprocessor components (e.g., secondary cache, main memory, external I/O bus, network interface, input devices, output devices, external memory devices, secondary storage, motherboard)
- system on a chip (SOC) – full computer on a chip.
- How do the internal and external parts of a computer work?
- How do microcomputers operate?
- What is meant by computer numeric control?
- What are the pros and cons of computer numeric control?
- What circuits/elements make up a microprocessor?
- What is the difference between a microprocessor and a microcomputer?
