# SLR11 Binary Flashcards

Unsigned binary

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

Signed binary

“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.”

Two’s complement

“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.”

Fixed-point binary form

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

Floating-point binary form

“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.”

Normalised floating-point form

“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.”

Underflow

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

Overflow

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

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