You wish to scan an 8 by 10 colour photograph using a scanner which can scan images at a resolution of 3200 dots per inch. The image will be scanned using 8 bit colour, i.e. 1 byte for each of the 3 colours R,G,B
a) How many bytes are required to store the photograph?
b) If your USB flash memory key has 16 GB of storage space. Using the definitions of a MB and a GB above , how many such images could be stored on your memory key?
c) If the photograph was in 8 bit grey scale rather than colour, how many such images could be stored on your memory key?

A character-interleaved time-division multiplexer is used to combine the data streams of a
number of 110-bps asynchronous terminals for data transmission over a 2400-bps digital line.
Each terminal sends asynchronous characters consisting of 7 data bits, 1 parity bit, 1 start bit,
and 2 stop bits. Assume that one synchronization character is sent every 19 data characters
and, in addition, at least 3 percent of the line capacity is reserved for pulse stuffing to
accommodate speed variations from the various terminals.
a. Determine the number of bits per character.
b. Determine the number of terminals that can be accommodated by the multiplexer.
c. Sketch a possible framing pattern for the multiplexer.
