Directions for Questions 34-38: Read the passage and answer the questions thatfollow on the basis of the information provided in the passage.

Multitasking by Windows

Multitasking lots you run several applications simultaneously. While you use a wordprocessor in the foreground, your Web browser can be downloading a file, unseenand unattended, in the background. As each application loads, the processorallocates a chunk of memory for the exclusive use of that application. When anapplication needs more memory, it sends a request to Windows, which checks to seehow much memory is available and assigns an additional free stretch of RAM tothat application. If there's not enough unallocated RAM to supply the application,Windows checks a table that shows how recently different sections of memory havebeen used. It then copies the contents of the oldest used RAM to virtual memory,hard disk storage your PC treats as if it were RAM. Windows then assigns the RAMto the application asking for it. Too little real RAM can result in extensive swapping

between memory and disk, which slows your PC,

To multitask all the programs loaded In memory, Windows assigns each program aslice of the processor's time. When one program's time using the processor is up,Windows instructs the processor to save whatever it's doing by writing the contentsof the processor's registers to RAM. Registers are like the processors scratch padswhere it stores data temporarily as it processes the data. Windows also saves adigital bookmark in the application's code to save its place.

After the processor has cleared the registers, the processor fills them again with newdata from the next program, and begins executing that program's Instructions froma new location In RAM until that program's time slice expires. Windows tells theprocessor to save those registers and repeat the process for the next applicationbeing multitasked. If a program needs the services of a PC's hardware, such as aprinter port or video card, Windows first checks whether another multitaskedprogram Is already using that service. If it's In use, Windows puts the now requestinto a queue until the current hardware operation is completed. Then Windowsgives the requesting program access to the hardware through drivers or the BIOS.

33) If there is insufficient RAM to run an application, Windows

a) Uses virtual memory instead of RAMb) Clears the RAM for the applicationc) Uses registers as the RAMd) Copies the contents of the oldest used RAM to virtual memory, then

assigns the RAM to the application

34) Multitasking means ,

a) Multiple programs are processed at any instant of timeb) Multiple programs are assigned a slice of the processor's timec) Multiple programs use the RAM through swapping

d) Multiple programs use the services of a single hardware

35) According to the passage, a program being processed if is in need of theservices of PC's hardware makes

a) Windows checks and puts a request to use it immediately as it iscurrently being processed

b) Windows checks and puts a request into queue if it is already in usec) Windows checks and puts a request into queue if it is already in use

and keeps processing the program until the current hardwareoperation is completed

d) Windows checks and puts a request into queue if it is already in useand stores the program in registers until the current hardwareoperation is completed

36) In multitasking, when one program slice of processor time is over

a) Processor writes contents of registers to RAM and from there tovirtual memory, the hard disk storage

b) Processor writes contents of registers to RAM and fills them againwith next programs instructions

c) Processor writes contents of registers to RAM and fills them againwith next programs data and executes program's instructions fromRAM

d) Processor writes contents of registers to RAM and starts executing thenext program from RAM

37) Choose the most accurate statement

a) If an application needs additional memory, it sends a request toWindows, which assigns available RAM to the application

b) If an application needs additional memory, 9 sends a request toWindows, which saves oldest used RAM to hard disk and assigns theRAM to application

c) If an application needs additional memory, it sends a request toWindows which saves oldest used RAM to virtual memory andassigns the RAM to application

d) If an application needs additional memory, it sends a request toWindows, which starts swapping between memory and disk to freesome RAM and assigns to the application
