Answer:

The answer is A

Explanation:

Basically, Shortest job first (SJF) is a scheduling policy that selects jobs on queue for execution within a short execution time.

From the definition of SJF above, it means that there are a lot of process on queue and the (SJF) job is to receive processes on queue to execute within a short execution time.

Therefore, if all the jobs or process arrives at the SJF at the same time, the SJF will forfeit one of its major purpose which is scheduling of jobs.

That will therefore not make Non-preemptive Shortest Job First (SJF) not function at its optimal point.

A transaction is a simple task carried out as part of corporate operations. Transaction processing systems (TPS) handle business transactions for the corporation, supporting overall enterprise operations.

Today, TPS are required for business operations in practically every firm. TPSs feed information into organizational databases; they also serve as the framework for management-oriented information systems. Source data automation frequently involves direct data entering. Electronic data interchange is being utilized by transaction processing systems more and more. These systems offer computer-to-computer communication without the need for repeated data entry by substituting paper documents with formatted transaction data sent over telecommunications networks.

The Java compiler does not check for an ArrayIndexOutorBoundsException during the compilation of a program containing arrays. O

yulyashka [42]

Answer:

TRUE

Explanation:

Let us first understand what is an ArrayIndexOutOfBounds Exception.
As the name itself suggests the index for the array has gone out of bound (permissible value) and an exception (anamoly) is resulted.
So, it throws an error.
That means if an array, Employee of size n is defined then the permissible elements are Employee[0] to Employee[n-1]. If any negative index or with the index is greater than n-1 is tried to access it throws an error saying ArrayIndexOutOfBounds Exception.
In java, during the compilation of the program the compiler doesn't check for the ArrayIndexOutOfBounds Exception.It checks during running the program.
So, it is called a Runtime Exception.
