At an Electronic Data processing unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day. The program operating must also satisfy the following conditions: 1. If program P is to be operated on a day, V can’t be operated on that day. 2. If Q is to be operated on a day, T must be one of the programs to be operated after Q. 3. If R is to be operated on a day, V must be one of the programs to be operated after R. 4. The last program to be operated on any day must be either S or U. If the program sets R and W are to be operated on the first day, which of the following could be the other program on that day?

If one day's routine is P,Q,W,T,U each of the following could be the next day's routine except
On a non-pipelined sequential processor, a program segment, which is a part of the interrupt service routine, is given to transfer 500 bytes from an I/O device to memory.     Initialize the address register     Initialize the count to 500 LOOP: Load a byte from device     Store in memory at address given by address register     Increment the address register     Decrement the count     If count! = 0 go to LOOP Assume that each statement in this program is equivalent to a machine instruction which takes one clock cycle to execute if it is a non-load/store instruction. The load-store instructions take two clock cycles to execute. The designer of the system also has an alternate approach of using the DMA controller to implement the same transfer. The DMA controller requires 20 clock cycles for initialization and other overheads. Each DMA transfer cycle takes two clock cycles to transfer one byte of data from the device to the memory. What is the approximate speedup when the DMA controller based design is used in place of the interrupt driven program based input-output?
Three friends want to hire a taxi for a trip. The taxi owner provides them with following three options: A. You can hire the taxi without an accompanying driver. This would cost you Rs. 2500 per day. Driver can be arranged from another agency for Rs. 500 per day. B. You can hire the taxi with driver from the first agency. This would cost you Rs. 2800 per day. But driver will have to be provided relief fund of Rs. 250 per day if total distance traveled exceeds 1500 KM. C. You can hire the taxi without an accompanying driver. This would cost you Rs. 2500 per day. Driver can be arranged from another agency for 50 paise per KM.  If the friends plan to travel to a place at a distance of 1500 kms and come back the next day, which tariff option should they choose? 
Which of the following statements is/are not true about the "Grid Organisation Development" (Grid OD) Program designed by Robert R. Blake and Jane S. Mouton?
1. It is a eight phase program lasting about three to five years.
2. Through this program, an organisation can move systematically from the stage of examining managerial behaviour and style to the development and implementation of an "ideal strategic corporate model".
3. Behavioural science concepts and rigerous business logic are combined in the Grid OD Program's six phases.
4. The single most significant premise on which Grid OD rests in that the 5, 5 way of doing business which is acknowledged universally by managers as the soundest way to manage to achieve excellence.
If R is the third exercise in a routine which of the following cannot be the second exercise in that routine.
In multi-programmed systems, it is advantageous if some programs such as editors and compilers can be shared by several users. Which of the following must be true of multi-programmed systems in order that a single copy of a program can be shared by several users? I. The program is a macro ll. The program is recursive lll. The program is reentrant
Assertion (A) Each role must have enough stressers which may help the role occupant to stretch himself/herself to meet the challenge. In the role, where the scope is limited to routine work, the role occupants do not perceive any challenge.
Reason (R) While every role has some routine elements, challenge can also be incorporated into every role. However, the challenge should not exceed an optimal limit, otherwise it may produce dysfunctional stress, resulting in poor performance or damage to the health of the employee in the long-run.
