We can combine simpler Boolean expressions to create more complicated Boolean expressions using the three logical operators and, or, and not.
These operators have the same semantics (meaning) as their English equivalents. For instance, x > 0 and x 10 only returns True if x is both more than 0 and less than 10. If any of the requirements, i.e., whether the number n is divisible by 2 or by 3, is true, then n% 2 == 0 or n% 3 == 0 is true.
A Boolean value is negated by the not operator, therefore not (x > y) is True if x > y is False, or if x is less than or equal to y. We can combine simpler Boolean expressions to create more complicated Boolean expressions using the three logical operators and, or, and not.

it takes 1 second of transmission delay to send a packet over a link. how many seconds does it take to transmit 100 packets over three hops? assume that all links have the same bandwidth and that all packets are the same size. ignore all other delays.
To transmit 100 packets over three hops, each packet must be transmitted over each of the three links, for a total of 3 transmissions per packet.
How to calculate transmissions of packets?
There is a 1 second transmission delay for each link, for a total of 3 seconds of delay per packet.
Therefore, the total time to transmit 100 packets over three hops can be calculated as follows:
Total time = (number of packets) x (number of transmissions per packet) x (delay per transmission)
Total time = 100 x 3 x 1
Total time = 300 seconds
So, it would take 300 seconds to transmit 100 packets over three hops, assuming all links have the same bandwidth and all packets are the same size, and ignoring all other delays.

consider the following code segment. int count = 0; int number = 10; while (number > 0) { number = number / 2; count ; } what will be the value of count after executing the code segment?
The value of count after executing the code segment will be 4.
Here is a step-by-step explanation of how the code segment works:
1. The code starts with initializing two variables, count and number, with the values of 0 and 10 respectively.
2. The while loop begins, and the condition is that the loop will continue as long as the number is greater than 0.
3. In the first iteration, the number is divided by 2, which results in 5. The count variable is then incremented by 1.
4. In the second iteration, the number is again divided by 2, which results in 2.5. However, since the number variable is an int, the value is rounded down to 2. The count variable is again incremented by 1.
5. In the third iteration, the number is divided by 2, which results in 1. The count variable is again incremented by 1.
6. In the fourth iteration, the number is divided by 2, which results in 0.5. However, since the number variable is an int, the value is rounded down to 0. The count variable is again incremented by 1.

suppose no lines/queues are permitted anywhere in the process (i.e., blocking can occur). if task b routes students to the first available task (c or d), what is the actual throughput for the entire sequence (i.e., at what rate will students exit task e, in students per minute)?
Without lines/queues, the throughput of the entire sequence will be determined by the bottleneck task with the slowest processing time.
In this case, task E has the longest processing time of 4 minutes, so the maximum throughput of the system is limited by the rate at which Task E can process students. If Task B routes students to the first available task (C or D), it does not affect the processing time of Task E. Therefore, the actual throughput for the entire sequence would still be limited by the slowest task, which is Task E with a processing time of 4 minutes. This means that the rate at which students exit Task E will be 15 students per hour or 0.25 students per minute (assuming there are no other factors that could further impact the throughput of the system). Without lines/queues, the throughput of the entire sequence will be determined by the bottleneck task with the slowest processing time.
