The "Leave" message type was added with IGMP Version 2.
IGMP, or Internet Group Management Protocol, is a network-layer protocol used by routers and hosts to manage the distribution of IP multicast traffic. IGMP Version 2 was an upgrade from the original IGMP Version 1 and introduced several new features, including the "Leave" message type. The Leave message allows a host to inform its local router that it no longer wants to receive multicast traffic for a specific group. This helps improve the efficiency of multicast delivery by allowing routers to prune branches of the multicast distribution tree that are no longer needed.

Consider the discussion in Section 1.3 of packet switching versus circuit switching
in which an example is provided with a 1 Mbps link. Users are generating
data at a rate of 100 kbps when busy, but are busy generating data only with
probability p = 0.1. Suppose that the 1 Mbps link is replaced by a 1 Gbps link.
a. What is N, the maximum number of users that can be supported simultaneously
under circuit switching?
b. Now consider packet switching and a user population of M users. Give a
formula (in terms of p, M, N) for the probability that more than N users
are sending data.
a. It can support a maximum of 1 Mbps / 100 kbps = 10 users simultaneously.
b. The formula would be calculated using N = 10 and M = the number of users being considered.
a. In circuit switching, a dedicated physical path is established between the sender and receiver for the duration of the communication. The maximum number of users that can be supported simultaneously is limited by the capacity of the link. In this case, the link has a capacity of 1 Mbps, so it can support a maximum of 1 Mbps / 100 kbps = 10 users simultaneously.
b. In packet switching, the data is divided into small packets, each of which is transmitted individually and can take a different path to reach its destination. With M users, the probability that more than N users are sending data at the same time is given by:
P(more than N users sending data) = 1 - (1 - p)^M
Where p = 0.1 is the probability that a user is busy generating data. This formula gives the probability that at least one of the M users is sending data. To find the probability that more than N users are sending data, we can subtract the probability that exactly N users are sending data:
P(more than N users sending data) = 1 - (1 - p)^M - (M choose N) * p^N * (1 - p)^(M-N)
Where (M choose N) is the binomial coefficient, which gives the number of ways to choose N items from M items.
With the 1 Gbps link, the maximum number of users N is still 10, so the formula would be calculated using N = 10 and M = the number of users being considered.

6. A microprocessor has an increment memory direct instruction, which adds 1 to the value in memory location. The instruction has five stages: fetch opcode (four bus clock cycles); fetch operand address (three bus clock cycles); fetch operand (three bus clock cycles); add 1 to operand (three bus clock cycles); and, store operand (three bus clock cycles).
a. By what amount (in percent) will the duration of the instruction increase if we have to insert two bus wait states in each memory read and memory write operation?
b. Repeat assuming that the increment operation takes 13 cycles instead of 3 cycles.
The percentage through which the duration of the instruction increase if we have to insert two bus wait states in each memory read and memory write operation is found to be 50%.
How we can determine the increase in duration?We can determine the increase in duration by calculating the number of cycles when bus wait states are not inserted into each memory read and memory write operation.
Total number of cyles = 4 + 3 + 3 + 3 + 3 = 16.
We would determine the number of cycles when two (2) bus wait states are inserted into each memory read and memory write operation as follows:
Number of cycles = (4+2) + (3+2) + (3+2) + (3+2) + 3.
= 6 + 5 + 5 + 5 + 3 = 24 cycles.
For the total wait state, we have total wait states = 24 - 16 = 8.
Now, we can calculate the increment in duration by using the formula which is as follows:
Increased duration = [tex]\frac{total wait states}{no. of cyles with no wait states} *100[/tex]= 8/16*100 = 50%.
Now we can assume that the increment operation takes 13 cycles. So, Similarly, we would determine the number of cycles when the bus wait state is not inserted into each memory read and memory write operation:
The total number of cycles = 4 + 3 + 3 + 3 + 13 = 26 cycles.
We would determine the number of cycles when two (2) bus wait states are inserted into each memory read and memory write operation as follows:
Number of cycles = (4+2) + (3+2) + (3+2) + (3+2) + 13
= 6 + 5 + 5 + 5 + 13 = 34 cycles.
Now, we can calculate the increment in duration by using the formula which is as follows:
Increased duration = [tex]\frac{total wait states}{no. of cycles with no wait states} *100[/tex]= 8/26*100 = 30.77%.

Consider sending packets from a source host to a destination host over a fixed route. Increase in which of the following delays is the most likely indication of an impending packet loss?
a.Transmission delay
b.Nodal processing delay
c.Propagation delay
d.Queuing delay
Queuing delay is the most likely indication of an impending packet loss.
What is Queuing delay ?When a packet must wait in line at a router before moving on to the next link in the path, this is referred to as the queuing delay. Packet loss may occur if packets are dropped or deleted if the queue fills up too much. The likelihood of packet loss increases with queue length, hence an increase in queuing delay is a warning that congestion is increasing and that packet loss may happen.On the other hand, the chance of packet loss is not a straightforward function of transmission delay, nodal processing delay, or propagation delay. The time it takes for a packet to be transmitted over a link is known as the transmission delay. The time it takes for a router to process a packet is known as the nodal processing delay.

A smartphone stores the following data for each photo that is taken using the phone.
- The file name of the photo
- The date and time the photo was taken
- The geographic location where the photo was taken
Assume that all of the photos that have been taken on the phone are accessible. Which of the following can be determined using the photo data described above?
I. The number of photos that were taken at a particular geographic location.
II. The number of photos that were taken in the last year
III. The name of the person who took the most recent photo
The correct options are:
I. The number of photos that were taken at a particular geographic location can be determined using the photo data described above.
II. The number of photos that were taken in the last year can also be determined using the date and time information for each photo.
What is the smartphone about?I. The number of photos that were taken at a particular geographic location can be determined using the geographic location information stored for each photo. For example, if the phone stores the latitude and longitude of each photo, you could search for all photos taken within a certain radius of a specific location to determine the number of photos taken there.
Therefore, in II. The number of photos that were taken in the last year can be determined by looking at the date and time information for each photo and counting the number of photos taken within the last 365 days.

Which one of the following statements can be used to extract the last five characters from any string variable str?
a) str.substring(str.length() - 5, str.length())
b) str.substring(5, 5)
c) str.substring(str.length() - 4, 5)
d) str.substring(str.length() - 5, 5)
a) str.substring(str.length() - 5, str.length())
The correct answer is a) str.substring(str.length() - 5, str.length()).
What is substring?Substring is a sequence of characters within a string. It can be a single character or a group of characters that are part of the string. Substrings are used in a variety of programming languages to perform certain operations on strings.
This statement will extract the last five characters of the string stored in the variable str. The first parameter of the substring method is the index of the first character to extract (in this case str.length() - 5) and the second parameter is the index of the last character to extract (in this case str.length()).
