What is RAM used for in a computer system?
• RAM stores data and programs currently in use. • It is volatile, meaning data is lost when the computer is powered off.
What is ROM and how is it different from RAM?
ROM stores permanent instructions (e.g., for booting). It is non-volatile and cannot be modified easily.
What is cache memory and why is it important?
Cache is high-speed memory near the CPU that stores frequently accessed data, speeding up processing by reducing RAM access.
What are registers in the CPU?
Registers are very fast, small memory locations inside the CPU used to store current instructions, data, or memory addresses.
What is virtual memory?
Virtual memory is part of the hard drive used as temporary RAM when physical RAM is full. It’s slower than real RAM.
What are two modern uses for a GPU besides rendering graphics?
Machine learning model training and scientific simulations, due to GPU’s parallel processing capabilities.
What do input and output devices do in a computer system?
Input devices send data into the system; output devices present data to the user. Their communication is managed by the OS and drivers.
