# SLR11 Binary Flashcards

1
Q

﻿Unsigned binary

A

“A binary number which uses every bit to represent the actual value, this means it can only represent positive numbers.”

2
Q

Signed binary

A

“A binary number which uses the Most Significant Bit (MSB) to represented the sign of the number, either 1 for negative or 0 for positive.”

3
Q

Two’s complement

A

“A method in computing of being able to store and represent floating-point real numbers (both positive and negative) as a string of pure binary digits. Uses the concepts of two’s complements, mantissa and exponent.”

4
Q

Fixed-point binary form

A

“A real data type for a number that has a fixed number of digits after (and sometimes also before) the radix point (binary point).”

5
Q

Floating-point binary form

A

“A real data type for a number where the number’s radix point (binary point) can “float”; that is, it can be placed anywhere relative to the significant digits of the number.”

6
Q

Normalised floating-point form

A

“A floating-point binary number that has been normalised has moved the binary point so that the first digit after the binary point is a significant digit. This process maximises the precision in a given number of bits, which means that the first two digits of a normalised floating-point number will always be different, 01 for positive and 10 for negative.”

7
Q

Underflow

A

“The generation of a number that is too small to be represented in the device meant to store it.”

8
Q

Overflow

A

“The generation of a number that is too large to be represented in the device meant to store it.”
