3.1 Binary (incomplete) Flashcards
What are the Number Systems and their Bases?
- Binary, Base 2
- Denary, Base 10
- Hexademical, Base 16
What is Binary?
Binary is a base 2 number system, having the digits 0 and 1 - which represent true and false, as well as voltage levels.
What is a bit?
A bit is the fundamental unit, 0 or 1.
What is the hierarchy of units in binary?
Bit → 1/0
Nibble → 4 Bits
Byte → 8 Bits.
Kibibytes → 1024 Bytes
Mebibyte → 1024 Kibibytes
Gibibyte → 1024 Mebibytes
Tebibyte → 1024 Gibibytes
Pebibyte → 1024 Tebibytes
What are the titles for the most left bit and the most right bit?
- Most Left → Most Significant Bit
- Most Right → Least Significant Bit
What is Signed Binary?
Signed Binary are binary values of positive and negative, containing 2 variables of Sign and Magnitude.
Signed binary has a Sign Bit, which is the MSB, at 1 it is negative, and at 0 it is positive.
It cannot be used to processing zeroes, because zero cannot be positive or negative.
