# SLR10 Number systems and Bases Flashcards

1
Q

﻿Natural number

A

“Any positive whole number, including 0 – e.g., 0, 1, 2, 3 …”

2
Q

Rational number

A

“A number that can be written as a ratio. In other words, it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. e.g. ½ ¾ …”

3
Q

Irrational number

A

“A number which cannot be written as a fraction – for example, √2.”

4
Q

Ordinal number

A

“When objects are placed in order, these are used to tell their position – e.g., if we have a well-ordered set S = {‘a’, ‘b’, ‘c’, ‘d’}, then ‘a’ is the first object, ‘b’ the second, and so on.”

5
Q

Decimal (base 10)

A

“A numerical system of notation which uses 10 as its base.”

6
Q

Binary (base 2)

A

“A numbering scheme in which there are only two possible values for each digit; 0 and 1. The term in computing refers to any digital encoding system in which there are exactly two possible states.”

7
Q

A

“A numerical system of notation which uses 16 rather than 10 as its base. The 16 Hex base digits are 0-9 and the letters A-F.”

8
Q

bit

A

“The smallest unit of storage in a computer system, represented by either a binary 1 or 0.”

9
Q

byte

A

“A collection of eight bits.”

14
Q

kilo

A
