5) You would write it as 4000, 300, 20, 1


6) Write the following numbers in binary (base 2)
21 =(1 x 16)+(1 x 4)+(1 x 1)
24= (1 x 16)+(1 x 8)
30= (1 x 16)+(1 x 8)+(1 x 4)+(1 x 2)

7) what is a byte ? unit of storage capable of holding a single character

8) How many bytes in a kilo, mega, giga and tera bytes?
kilo: 1000
Mega: 1000000
Giga: 1000tera: 1000000000000

9) Complete the following conversions;
1000 Mb = 0.09765625Gb
500 Gb = 512 000Mb
5000 Kb = 4.8827125Mb
