Explanation of Solution
Device working with binary data:
A device that process or deals with the binary data is termed as “digital device”. Computer is an example of a digital device.
Binary numbers are important for computer processing and can be represented with two digits 0 and 1.
- • Each 0 or 1 in a binary number is also called bits.
- • All the operations and calculations are performed by the computer either in ON or OFF position...

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.

Re-write the withdraw() method in the CheckingAccount class so that it first checks if the withdrawal amount is less than the current balance plus the overdraft limit. If it is, the withdrawal is allowed and the balance is updated. If not, the method should return an error message "Insufficient funds".
