Expert Solution & Answer
Chapter 24, Problem 8PE
Explanation of Solution
Pseudo code:
delete(value Ki)
begin
j=first i high-order bits of h(Ki);
delete value Ki from bucket j;
coalesce (bucket j);
end
coalesce (bucket j)
begin
ij = bits used in bucket j;
k = any bucket with first (ij - 1) bits same as that
of bucket j while the bit ij is reversed;
ik = bits used in bucket k;
if (ij ≠ jk)
//bucket cannot be merged.
return;
if (entries in j + entries in k > bsize)
//buckets cannot be merged

Question D.4: FIFO Page Replacement
Consider the following page reference string:
e, c, b, e, a, g, d, c, e, g, d, a
Considering 4 frames, fill in the following table and then answer how many page faults would occur with the
FIFO page replacement algorithm.
RS: reference string; FO: frame 0, F1: frame 1, etc.
Hint: all frames are initially empty, so your first unique pages will all cost one fault each.

Consider a system that uses a fixed-partition scheme, with equal partitions of size 2" bytes, and the main
memory has 2¹8 bytes. A process table is maintained with a pointer to the resident partition for each resident
process. How many bits are required for the pointer in the process table? Show all your steps.
