### Question

a) How many milliseconds (ms) are in 1 second?

b) How many microseconds (μs) are in 1 second?

c) How many nanoseconds (ns) are in 1 millisecond?

d) How many microseconds are in 1 millisecond?

e) How many nanoseconds are in 1 microsecond?

f) How many kilobytes (KB) are in 1 gigabyte (GB)?

g) How many kilobytes are in 1 megabyte (MB)?

h) How many megabytes are in 1 gigabyte (GB)?

i) How many bytes are in 20 megabytes?

j) How many kilobytes are in 2 gigabytes?

### Answer

a. One second is 1000 or 103 milliseconds. Milliseconds are represented as ms.
b. One second is 1000000 or 106 microseconds. Microseconds are represented as .
c. One millisecond is 1000000 or 106 nanoseconds. Nanoseconds are represented as ns.
d. One millisecond is 1000 or 103 microseconds. Microseconds are represented as .
e. One microsecond is 1000 or 103 nanoseconds. Nanoseconds are represented as ns.
f.One gigabyte (GB) is 230 kilo bytes (OR) 1 gigabyte =106 kilobytes.
g. One megabyte (MB) is 220 kilobytes (OR) 1 megabyte = 103 kilobytes.
h. One gigabyte (GB) is 210 megabytes OR 1 gigabyte = 103 megabytes
i. 20 megabytes = 20*220 bytes.
j. 2 gigabytes = 2*230 bytes.
