Lesson 1 Flashcards
Covers the difference between analogue and digital data, data representation, number conversions and Horner's method
prefix for binary numbers
0b
prefix for hexadecimal numbers
0x
What is Horner’s method?
Dividing continuously by the number base
continuous data
data that can take any value in a given range
discrete data
data that can only use a set of fixed values
quantisation
the process of mapping continuous values onto a smaller set of discrete values
compared to analogue data, digital data is much more ________ to noise
resistant
assume non-annotated bases are base..?
10
bit is always written…?
in lowercase
byte is always written…?
capitalised
a word
several bytes (use varies)
range of values for ‘n’ number of bits (binary)
2^n
range of values for ‘n’ number of bits (hexadecimal)
16^n
horner’s method
dividing/multiplying by a base other than 10 to convert in/out of decimal
which unicode encoding is equivalent to ascii?
UTF-8
