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.

Which type of rule prevents the creation of orphan records?
redundancy constraint
integrity constraint
conflict requirement
security requirement
Answer:
Explanation:
The type of rule that prevents the creation of orphan records is an integrity constraint. An integrity constraint is a rule that ensures data consistency and accuracy in a database by enforcing certain conditions on data values. For example, a foreign key constraint is a type of integrity constraint that ensures that a record in one table that refers to a record in another table must have a corresponding record in the referenced table. This helps to prevent the creation of orphan records, which are records in a table that have no corresponding records in related tables.
The type of rule that prevents the creation of orphaned records is an integrity constraint.
Integrity constraints are used to ensure that the data in a database is accurate and consistent. One type of integrity constraint is the referential integrity constraint, which is used to prevent the creation of orphan records. An orphan record is a record that does not have a corresponding parent record in another table.
For example, if you have a student table and a class table, and each student record includes a class ID, an integrity constraint will prevent you from creating a student record with a class ID that does not exist in the class table. This ensures that there are no "orphan" records in the database.
In conclusion, an integrity constraint is the type of rule that prevents the creation of orphaned records.

In F. Scott Fitzgerald's "The Great Gatsby," the message that he was trying to send not only with the crash but also with the elements leading up to the crash was that the American Dream was ultimately flawed and illusory.
Fitzgerald used the characters and events in the novel to critique the idea of the American Dream, which promised that anyone could achieve success and happiness through hard work and determination. Through the lives of Jay Gatsby, Tom and Daisy Buchanan, and other characters, Fitzgerald showed how this promise was ultimately empty, and how the pursuit of wealth, power, and status could lead to moral decay, corruption, and even tragedy.

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
