Multiple Choice

What is the main function of the processor in a computer system?

• To store data

• To execute instructions

• To manage memory

• To connect peripherals

Multiple Choice

What is the main difference between RAM and ROM?

• RAM is non-volatile, ROM is volatile

• RAM is read-only, ROM is read-write

• RAM is volatile, ROM is non-volatile

• RAM is slower than ROM

Multiple Choice

RAM is....

• where information is stored

• is the working memory of a computer

• the backbone of the computer

• what executes the commands from the hardware or software

Multiple Choice

Memory (RAM) is...

• A large male goat

• A big Dodge truck

• Random Access Memory (working memory)

• Sticks of goodness

Multiple Choice

What is the main difference between volatile and non-volatile memory?

• Volatile memory is faster than non-volatile memory

• Volatile memory loses its data when power is turned off

• Non-volatile memory is used only in mobile devices

• Non-volatile memory is more expensive than volatile memory

Multiple Choice

What is the impact of having more RAM on a computer system's performance?

• It allows more programs to run simultaneously

• It decreases the need for virtual memory

• It has no effect on performance

• It increases the speed of the processor
