Question :
A small computer on a smart card has four page frames. At the first clock tick, the R bits are 0111 (page 0 is 0, the rest 1).
At subsequent clock ticks, the values are 1011, 1010, 0101, 1010, 0010, 1100, and 0001.
If the aging algorithm is used with an 8-bit counter, give the values of the four counters after the last tick.
