Which MS excel function calculates the no of days between 2 dates?1. Gap2. Dates3. Days4. Days 3605. SPAN

Answer» Correct Answer - Option 3 : Days

The correct answer is Days.

  • The Excel DAYS function returns the number of days between two dates.
  • With a start date in A1 and an end date in B1, =DAYS(B1, A1) will return the days between the two dates.
  • Purpose: Get days between dates.
  • Return value:  A number representing days.
  • Syntax: =DAYS (end_date, start_date)
  • Arguments: 
    • end_date - The end date.
    • start_date - The start date.
  • Usage notes: 
    • The DAYS function returns the number of days between two dates.
    • Both dates must be valid Excel dates or text values that can be parsed as dates.
    • The DAYS function only works with whole numbers, fractional time values are ignored.
    • If a start and end date are reversed, DAYS returns a negative number.
    • The DAYS function returns all days between two dates, to calculate working days between dates, see the NETWORKDAYS function.

OS process management, difference between arrival time and time at which process first gets the CPU is called _______ time1. Event 2. Burst3. Response4. Waist5. Turnaround

Answer» Correct Answer - Option 5 : Turnaround

The correct answer is Turnaround.

  • Turnaround time:
    • Operating System(OS) process management, the difference between arrival time and time at which process first gets the CPU is called Turnaround time.
    • Turnaround time is the total amount of time spent by the process from coming in the ready state for the first time to its completion.
    • Turnaround time = Burst time + Waiting time
    • or
    • Turnaround time = Exit time - Arrival time
    • For example, if we take the First Come First Serve scheduling algorithm, and the order of arrival of processes is P1, P2, P3 and each process is taking 2, 5, 10 seconds. Then the turnaround time of P1 is 2 seconds because when it comes at 0th second, then the CPU is allocated to it and so the waiting time of P1 is 0 sec and the turnaround time will be the Burst time only i.e. 2 seconds.
    • The turnaround time of P2 is 7 seconds because the process P2 have to wait for 2 seconds for the execution of P1 and hence the waiting time of P2 will be 2 seconds. After 2 seconds, the CPU will be given to P2 and P2 will execute its task. So, the turnaround time will be 2+5 = 7 seconds. Similarly, the turnaround time for P3 will be 17 seconds because the waiting time of P3 is 2+5 = 7 seconds and the burst time of P3 is 10 seconds. So, the turnaround time of P3 is 7+10 = 17 seconds.
    • Different CPU scheduling algorithms produce different turnaround time for the same set of processes.
    • This is because the waiting time of processes differ when we change the CPU scheduling algorithm.

Answer» Correct Answer - Option 2 : Program counter

The correct answer is Program counter.

  • Program Counter:
    • A program counter (PC) is a CPU register in the computer processor which has the address of the next instruction to be executed from memory.
    • It is a digital counter needed for faster execution of tasks as well as for tracking the current execution point.
    • A program counter is also known as an instruction counter, instruction pointer, instruction address register or sequence control register.
    • Similar to other process registers of the computer, the program counter is like a bank of binary latches, with each representing one bit of value.
    • The program counter works in combination with other registers to identify the current instruction.
    • It can be modified or accessed with the help of access or jump instructions.
    • The PC can be accessed/modified by jump and branch instructions.
    • Therefore, the destination address can be loaded to the program counter via branch instructions.
    • The program counter can also be loaded with the address using the data processing instructions.
