For 2kb
1 byte = 8 bits.
1 Kilobyte = 8 x 10³ Bits.
1 Kilobyte = 8 x 1000 Bits.
1 KB = 8000 bits.
.:. 2kb = 8000 x 2 = 16,000bits
For 2mb
1mb = 1000kb
.:. 2mb = 2000kb
Where 1kb = 8000 bits,
Then to find 2000kb in bits
= 8000 x 2000
=16,000,000 bits
(3bii)
The total storage of the two devices in bits = 16,000 + 16,000,000
= 16,016,000 bits
.:. Changing to bytes
= 8 bits = 1 byte
.:. 16,016,000 bits = ?
= 2,002,000 bytes
