The unit that performs scheduling of instructions by determining the data dependencies is Correct Answer dispatch-execute unit

The dispatch-execute unit performs scheduling of instructions by determining the data dependencies after which the microoperations of the scheduled instructions are executed in the execution unit.

Consider the following four relational schemas. For each schema, all non-trivial functional dependencies are listed. The underlined attributes are the respective primary keys. Schema I: Field ‘courses’ is a set-valued attribute containing the set of courses a student has registered for. Non-trivial functional dependency: rollno → courses Schema II: Non-trivial functional dependencies: rollno, courseid → email email → rollno Schema III: Non-trivial functional dependencies: rollno, courseid → marks, grade marks → grade Schema IV: Non-trivial functional dependencies: rollno, courseid → credit courseid → credit Which one of the relational schemas above is in 3NF but not in BCNF?

Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.

One of the Scheduling method is also known as Shortest-­next­-CPU­-burst algorithm, because scheduling through this method depends on the length of the next CPU burst of a process rather than its total length. Which of the following scheduling method is being discussed here?
Consider the following code sequence having five instructions I1 to I5. Each of these instructions has the following format.
