An 8-bit binary register contains the value: 0 0 1 1 0 1 1 0
a) Write down the denary value of this register. [1]
b) The contents of this register undergo a logical shift one place to the right.
i Show the result of this right shift.
ii Write down the denary value following this right shift. [2]
c) The contents of this register, at the start of the question, now undergo a logical shift two places to the left.
i Show the contents of the register after this left shift operation. [1]
ii State, with reasons, the effect of this shift on the denary value in part a. [2]

a) Explain the term pixel. [1]
b) Explain the term colour depth. [1]
c) Calculate how many of these images could be stored on a 32-GiB memory stick. [3]
d) Describe how it would be possible to increase the number of these images which could be stored on this memory stick. [3]
