Answer:

Explanation:

L/R=2 microsecond or 0.000002 s, traffic intensity I is 0.000002 * 450,000 = 0.9

Queuing delay = I *L/R*(1-I)= 0.000002*0.9*0.1=0.18 microsecond

The average queueing delay at the given link is 0.9 milliseconds.

Calculating the Average Queueing Delay:

The average queueing delay at a link can be calculated using the formula:

Average Queueing Delay = (Packet Size * Packet Arrival Rate) / Link Capacity

In this case, the packet size is 2000 bits, the packet arrival rate is 450,000 packets per second, and the link capacity is 1 Gbps (1 billion bits per second). Plugging in these values into the formula, we get:

Average Queueing Delay = (2000 * 450,000) / 1,000,000,000

Solving this equation, the average queueing delay is 0.9 milliseconds.

The program outputs 11 numbers which are the first 11 Fibonacci numbers. The program uses a loop that goes through each number and checks if the sum of two values, "a" and "b", is equal to the loop variable "x".

What does this program do?

In the program, there is a "for" loop that iterates from 1 to 11. For each iteration, it inputs a number "n" and then calculates the value of "b" as the integer division of "n" by 10. If the condition "a + b == x" is satisfied, it outputs the value of "n".

Since the input values are the first 11 Fibonacci numbers (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89), they will all be output because the condition "a + b == x" is always true.

Address Resolution Protocol (ARP) is a protocol used for mapping an Internet Protocol (IP) address to a physical machine address (MAC Address) that is recognized in the local network. It is used to discover the MAC address of any host on the local network.

Address Resolution Protocol (ARP) is a protocol used to map an Internet Protocol (IP) address to a physical machine address, such as a Media Access Control (MAC) address. ARP is used to discover the MAC address of any host on a local area network (LAN) so that data can be sent from one host to another. The IP address is used to identify the host, while the MAC address is used to identify the physical port of the host. ARP operates by broadcasting a request to all hosts on the LAN, asking the host with the specific IP address to identify itself. The host with the specified IP address then responds with its MAC address. This is how ARP resolves the IP address to the MAC address.
