1millisecond=103microseconds

e.

Explanation of Solution

Explanation:

According to measurement unit, one microsecond is equal to 103 nanoseconds. It is mathematically represented as follows

1microsecond=103nanoseconds

f.

Explanation of Solution

Explanation:

1Byte=8bits

1KiloByte(KB)=1024Bytes

1MegaByte(MB)=1024KB

1GigaByte(GB)=1024MB

1GB=1024×1024MB

1GB=106or220KB

Therefore, one Giga Byte is equal to 106or220 Kilo Bytes.

g.

Explanation of Solution

Explanation:

1Byte=8bits

1KiloByte(KB)=1024Bytes

1MegaByte(MB)=1024KB

Therefore, one Mega Byte is equal to 103or210 Kilo Bytes.

h.

Explanation of Solution

Explanation:

1Byte=8bits

1KiloByte(KB)=1024Bytes

1MegaByte(MB)=1024KB

1GigaByte(GB)=1024MB

Therefore, one Giga Byte is equal to 103or210 Mega Bytes.

i.

Explanation of Solution

Explanation:

1Byte=8bits

1KiloByte(KB)=1024Bytes

1MegaByte(MB)=1024KB

1MB=1024×1024Bytes

1MB=220Bytes

20MB=20×220Bytes=10×221Bytes

Therefore, 20 Mega Bytes is equal to 10×221 Bytes.

j.

Explanation of Solution

Explanation:

1Byte=8bits

1KiloByte(KB)=1024Bytes

1MegaByte(MB)=1024KB

1GigaByte(GB)=1024MB

1GB=1024×1024MB

1GB=220KB

2GB=2×220KB=221KB

Therefore, two Giga Bytes is equal to 221 Kilo Bytes.
