HL 1.2 - Memory

What is the purpose of RAM in a computer system

• RAM is used to save documents when the computer is switched off

• RAM is used to boot up the computer

• RAM stores input from the keyboard and mouse

• RAM stores running programmes and data and the CPU can access this quickly

What is primary storage?

• Storage using tape drives

• Memory that can be accessed directly by the CPU

• Memory where the data is saved when the computer is switched off

• The use of virtual memory to speed up a computer

What does non-volatile storage mean

• Data is not passed between the ram and the CPU

• When the power is switched off, data is lost and not saved on the device

• When the power is switched off, data is saved onto external storage

• When the power is switched off, data is saved on the storage device

Why does the computer require secondary storage?

• To access programs that are currently running

• To store data, files and software for future use

• To access the data stored in CPU cache

• To organise the virtual memory

What is the definition of a bit?

• A small part of a computer

• a binary digit, either 0 or 1

• A part of the CPU

• A number system used by computers

What are the smallest units of data used by a computer (the two digits)?

• 1 and 0

• 1 and 2

• 0 and 2

Which list is in the correct order, from the smallest unit to the largest?

• Terabyte, Gigabyte, Megabyte, Kilobyte

• Gigabyte, Terabyte, Kilobyte, Megabyte

• Kilobyte, Megabyte, Gigbyte, Terabyte

• Megabyte, Terbyte, Kilobyte, Gigabyte

What is the character set that uses 8-bit binary code?

• More ASCII

• Don't ASCII

• Entendable ASCII

• Extended ASCII
