A
can only take 2 values: 0 or 1 and is represented by a LOWERCASE b
2
Q
What is a byte and how it is represented?
A
made of 8 bits and is represented by a CAPITAL b
3
Q
What is a nybble?
A
half a byte = 4 bits
4
Q
How do you figure out the amount of different values that can be represented with a given number of bits?
A
2^number of bits
5
Q
What are the binary prefixes you have to learn?
A
- Kibi (Ki) - 2^10 = 1024
- Mebi (Mi) - 2^20 = 1048576
- Gibi (Gi) - 2^30 = 1073741824
- Tebi (Ti) - 2^40 = 1.0995x10^12
6
Q
What is 1 Kib?
A
1 kibibit = 2^10 bits
7
Q
What is 1 KiB?
A
1 kibibyte = 2^10 bytes
8
Q
What can we use to describe quantities of bytes?
A
- binary prefixes (powers of 2)
- decimal prefixes (powers of 10)
