Consider a buffer pull with three pages only, and the following sequence of requests, where each number is the ID of a disk page: 1 2 3 3 1 4 2 5 1 4 Suppose we use the "clock" replacement policy. Assume the clock hand rotates clockwise. Every time the clock replaces a buffer, it automatically moves to the next buffer.
Compute the following numbers:
- Number of disk IOs
- Remaining blocks in the buffer pool
- The number of hits
Which of the following statements is true:
a - The number of disk IOs is 8
b- The number of hits is 5
c- The number of hits is 4
d - The number of hits is 1
