Question 1

BINARY UNITS

Answer 1

: 1 bit (b) = 1 zero or one (binary digit)
0, 1
: 1 nibble = 4 bits
1001
: 1 byte (B) = 8 bits OR 2 nibbles
1110 0100
E.g. 2 B = 16 b
E.g. 48 b = 6 B

Question 2

METRIC PREFIXES

Answer 2

: Kilo (K) = 1,000 (103)
: Mega (M) = 1,000,000 (106)’
X 1000
: Giga (G) = 1,000,000,000 (109)
: Tera (T) = 1,000,000,000,000 (1012)
=
E.g. 2 Kb 2000 b
E.g. 2.5 TB = 2500 GB
Peta (P) = 1,000,000,000,000,000 (1015)
