    Solutions

S1. Ans.(b)

Sol. Cache memory also called CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.

S2. Ans.(e)

Sol. Spooling is a technique to hold data temporarily in the computer memory and provide to devices when they need it. The temporary holding area of the memory is sometimes referred to as the buffer. One common example of spooling is printing, where files are stored in the buffer and sent to the printer when it is ready.

S3. Ans.(a)

Sol. At the time of the booting process, all necessary files of the operating system are copied to the main memory (RAM) FROM HARD DISK. These files contain all necessary information to start the computer and initiate the input-output process.

S4. Ans.(d)

Sol. The clock rate(frequency of the processor) is the hardware dependent quantity it is fixed for a given processor

S5. Ans.(e)

Sol. A microprocessor sometimes called a logic chip, is a computer processor on a microchip. The microprocessor contains all, or most of, the central processing unit (CPU) functions and is the "engine" that goes into motion when you turn your computer on

S6. Ans.(a)

Sol. Direct memory access (DMA) is a method that allows an input/output (I/O) device to send or receive data directly to or from the main memory, bypassing the CPU to speed up memory operations. The process is managed by a chip known as a DMA controller (DMAC).

S7. Ans.(b)

Sol. When a looping or branching operation is carried out the offset value is stored in the cache along with the data.

S8. Ans.(a)

Sol. In this, only a part of the program getting executed is stored on the memory and later swapped in for the other part. An embedded system would normally use overlays because of the limitation of physical memory, which is internal memory for a system-on-chip, and the lack of virtual memory facilities

S9. Ans.(b)

Sol. The program counter (PC) holds the address of the next instruction to be executed, while the instruction register (IR) holds the encoded instruction. Upon fetching the instruction, the program counter is incremented by one "address value" (to the location of the next instruction).

S10. Ans.(e)

Sol. CPU utilization refers to a computer's usage of processing resources or the amount of work handled by a CPU. Actual CPU utilization varies depending on the amount and type of managed computing tasks.
