olchik [2.2K]

Answer and explanation:

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

1 second = 1000 milliseconds

1 second = $10^3$ milliseconds

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

1 second = 1000000 microseconds

1 second = $10^6$ microseconds

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

1 millisecond = 1000000 nanoseconds

1 millisecond = $10^6$ nanoseconds

d) How many microseconds are in 1 millisecond?

1 millisecond = 1000 microseconds

1 millisecond = $10^3$ microseconds

e) How many nanoseconds are in 1 microsecond?

1 microsecond = 1000 nanoseconds

1 microsecond = $10^3$ nanoseconds

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

1 gigabyte = 1000000 kilobytes

1 gigabyte = $10^6$ kilobytes

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

1 megabyte = 1000 kilobytes

1 megabyte = $10^3$ kilobytes

h) How many megabytes are in 1 gigabyte?

1 gigabyte = 1000 megabytes

1 gigabyte = $10^3$ megabytes

i) How many bytes are in 20 megabytes?

1 megabytes = 1000000 bytes

20 megabytes = 20000000 bytes

20 megabytes = $2\times 10^7$ bytes

j) How many kilobytes are in 2 gigabytes?

1 megabyte = 1000 kilobytes

2 megabyte = 2000 kilobytes

2 megabyte = $2\times 10^3$ kilobytes
