The FIFO (First In First Out) algorithm replaces the oldest page in the frame, so the page that was brought in first is replaced first.

For the given page reference string, the FIFO algorithm would incur the most page faults when using three frames, and the Optimal algorithm would incur the least page faults when using four frames. The page fault count for the other algorithms would fall in between these two extremes.

For the given page reference string, the number of page faults that would occur for each of the replacement algorithms, assuming three and four frames, is as follows:

a) FIFO replacement:

With three frames: 9 page faults

With four frames: 8 page faults

b) Optimal replacement:

With three frames: 6 page faults

With four frames: 5 page faults

c) LRU replacement:

With three frames: 8 page faults

With four frames: 7 page faults

The FIFO (First In First Out) algorithm replaces the oldest page in the frame, so the page that was brought in first is replaced first. The Optimal algorithm replaces the page that will not be used for the longest time in the future, while the LRU (Least Recently Used) algorithm replaces the page that has not been used for the longest time in the past.

An intruder transmitting packets from the outside with a source ip address field containing an address of an internal host is known as ip address SPOOFING.

IP address spoofing is a malicious practice that puts computer networks and users at risk. It occurs when an intruder transmits packets from the outside with a source IP address field containing an address of an internal host. This technique is used to gain unauthorized access to a network, hide the true identity of the sender, and even launch a denial-of-service attack. As a result, it is important to understand what IP address spoofing is, how it works, and the security measures that can be taken to protect oneself from it.

First, it is important to understand what IP spoofing is and how it works. IP spoofing is essentially a type of network attack where the attacker modifies the source address of an IP packet to make it appear as though the packet originated from a different source. This is done by changing the origin of the packet to the internal address of another user on the network, allowing the attacker to gain access to the network and perform malicious activities. The intruder can then use this access to steal information, launch a denial of service attack, or even gain control of the network.
