- 1True or false: Is virtual memory faster than RAM?False:
Virtual memory isn't faster than RAM - 2What is the correct order of bytes starting from Bit to Petabyte?Bit, Nibble, Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte.
- 3What component will store data currently being used?RAM stores data which is currently being used in files, operating systems and programs.
- 4The more cache your CPU HAS: a) The less time spent accessing memory, therefore programs run faster. b) The more time spent accessing memory, therefore programs run slower.The more cache the CPU has the less time spent accessing memory, therefore programs run faster.
- 5How much storage space does each character of Unicode need?16 bits (2 bytes)
- 6What data type would be used to store codes ( such as barcodes and phone numbers)?Real
- 7What character set is used on a smartphone or tablet?Unicode is used on a smartphone or tablet.
- 8The area in the CPU which stores regularly stored data is known as?The cache
- 9Secondary storage is: a) Non-volatile b) Back up storage c) An external hard drive d) A hard drive in the computer systemNon-volatile
- 10True or false? Unicode is 16 bits (2 bytes) and it can extended to display more characters with 32 bits (4 bytes)True it can be extended
- 11Why is secondary storage important?To store files needed for the computer to run.
- 12How much storage space does each character of ASCII need? a) 8 bits b) 7 bits7 bits is needed for each character
- 13Which of the following has the fastest clock speed? a) 900MHz b) 2.4GHz c) 5000KHz d) 1,000,000,000Hz2.4GHz
- 14How much storage is needed for extended ASCII? a) 8 bits b) 7 bits c) 1 bit d) 16 bits8 bits
- 15A dual core processor will... a) Have two processors which preform the fetch, decode, execute cycle simultaneously. This makes it twice as fast. b) Have two processors which preform the fetch, decode, execute cycle simultaneously. This means more instructions can be carried out at once, making it faster.b) Have two processors which preform the fetch, decode, execute cycle simultaneously. This means more instructions can be carried out at once, making it faster.
- 16Which of the following has the highest capacity? a) Cache (CPU) b) RAM c) Secondary storage (hard drive)Secondary storage has the highest capacity out of the options.
- 17What will having a processor with higher cache, more cores or a higher clock speed result in?Programs will be loaded faster.
- 18What data type uses true or false values? a) String b) Integer c) Boolean d) RealReal is used for true or false values.
- 19Which python code isn't related to iteration? a) IF, ELIF, ELSE b) For i in range( ) c) WhileIF, ELIF, ELSE
