What hardware defines a computer?
CPU and GPU
CPU and memory
CPU and storage
What does 'volatile' mean for a computer's memory?
Data and instructions remain stored even when the computer is switched off
Data and instructions may cause the computer to crash
Data and instructions are lost when the computer is switched off
Which is the fastest kind of memory for the CPU to access?
Random access memory
Level-1 cache memory
Level-2 cache memory
Which of these is often true about a RISC mobile processor when compared to a CISC processor?
RISC processor speed is faster than CISC so games and video playback are faster
The RISC processor has a larger set of instructions
The RISC processor speed is slower to preserve battery life and avoid overheating
Which types of memory might be used when the computer swaps data in and out of virtual memory?
Random access memory and cache memory
A hard disk drive and random access memory
A hard disk drive and cache memory
What is 'benchmarking'?
A test used to measure the amount of memory that a computer has
A test used to measure the number of cores in a CPU
A test used to measure the performance of a computer
Which of these cannot be changed once a program has been stored there?
RAM
PROM
EEPROM
How does data travel between the processor and the computer's RAM?
Through the expansion ports
Using peripherals
Using buses
Which of these scenarios is NOT the result of overclocking?
The computer will end up displaying the incorrect time and date
Processes might not be completed before the next instruction is carried out
The CPU could overheat
What is 'cache'?
It stores program operations and data while a program is being executed
It executes programs using the fetch-decode-execute cycle
It is a small amount of memory which is a part of the CPU
