◉What is an integer? Answer: Integers are any positive or negative
whole numbers
◉What is a rational number? Answer: Rational numbers include values
that can be expressed as fractions or ratios
◉What is an irrational number? Answer: An irrational number are
numbers that cannot be written as fractions.
◉What is a real number? Answer: A real number is a number either
rational or irrational that are used for measurement.
◉What are ordinal numbers? Answer: Ordinal numbers can be used to
describe the position in which values appear
◉What is the decimal number system? Answer: Base 10 positional
number system consisting of 10 digits; 0-9
,◉What is the base of number systems? Answer: The number of
symbols used to construct values
◉What is the mantissa? Answer: the part of a floating-point number
which represents the significant digits of that number.
◉What is the exponent? Answer: The position of the binary point in the
number
◉What is hexidecimal? Answer: Hexadecimal (or hex) is a base 16
system which uses numbers 0-9 and letters A-F
◉What are three benefits of hexidecimal? Answer: - easier to read and
remember
- quicker to write or type

◉What is a bit? Answer: An individual digit in a binary value
◉What is a byte? Answer: A byte is a collection of 8 bits
◉What is ASCII code? Answer: An alphanumeric code, which includes
letters as well as numbers
, ◉What is the difference between ASCII and unicode? Answer: ASCII
encodes symbols, digits, letters, etc., whereas Unicode encodes special
texts from different languages, letters, symbols, etc.
◉What can transmission errors be caused by? Answer: - electrical
interference
- power surges
- synchronisation issues
- wear and tear on the cable
◉Name four techniques that can be used to check for transmission errors
Answer: - parity bits
- majority voting
- check digits
- checksums
◉How is parity bits used to check for transmission errors? Answer: A
parity bit is an additional bit that is used to check that the other bits
transmitted are likely to be correct
◉How is majority voting used to check for transmission errors?
Answer: Majority voting is a system that requires each bit to be sent
