8.Given three switch processes, when they occur match them (1) Clock Interrupt A- The processor encounters a virtual memory address reference for aword that is not in the main memory. (2) I/O Interrupt B- The operating system determines whether the currently running process has been executed for the maximum allowable time slice. (3) Memory fault C- The operating system determines the I/O action that occurs.
Which one of the following statements is true for the voltages in a series RL circuit?
Options: The total voltages is equal to the sum of the voltages across the resistance and inductance, The voltage always has the same amplitude and phase for every part of the circuit, The total voltage is less than the sum of the voltages across the resistance and inductance, The total voltage lags the total current by less than 90
Concurrency control is important for which of the following reasons?
Options: To ensure data integrity when updates occur to the database in a multiuser environment, To ensure data integrity when updates occur to the database in a single-user environment, To ensure data integrity while reading data occurs to the database in a multiuser environment, To ensure data integrity while reading data occurs to the database in a single-user environment
What will the function randomize() do in Turbo C under DOS?
Options: returns a random number., returns a random number generator in the specified range., returns a random number generator with a random value based on time., return a random number with a given seed value.
A p- channel enhancement type MOSFET performs much the same function as a PNP transistor, except that
Options: it operates much faster, it is considerably larger, it is controlled by voltage rather than by current, so that it requires very little current at the control terminal, it is controlled by current rather than by voltage like a bipolar transistor.
