Solution
S1. Ans.(b)
Sol. Direct Memory Access (DMA) enables selective hardware to directly fetch memory of the computer system i.e. RAM.
S2. Ans.(a)
Sol. System software is developed to serve as a bridge between the hardware and the user, as the software directly communicates with the hardware. Operating systems and debuggers are two best examples of system software.
S3. Ans.(d)
Sol. File compression is the technique used to store the large file in a small storage space. It compresses to content of the file in such a way that there is no harm done on the file content and quality.
S4. Ans.(c)
Sol. Spooler is a program in computing that is used to line up print jobs by storing them in the buffer for a short time and allows the printer to print at the time when it is use.
S5. Ans.(b)
Sol. POST is a diagnostic testing sequence of a computer that is run before the actual booting to ensure that the computer hardware is functioning well. It stands for ‘Power-On Self-Test’.
S6. Ans.(c)
Sol. Control unit, arithmetic-logic unit and primary storage are the parts of the CPU. The storage unit deals with the allocation of memory to the processed data, the Control Unit (CU) controls the flow and processing of the data and the Arithmetic Logic Unit (ALU) carries out of the arithmetic operations of calculations of the computer system.
S7. Ans. (d)
Sol. Output devices can be used to view/ print data. Output devices provide processed output by the system to the user.
S8. Ans. (a)
Sol. Secondary storage is non-volatile.
S9. Ans. (c)
Sol. Majority of buffers use the faster RAM to store temporary data, not the ROM, due to the much faster access time compared with hard disk drives.
S10. Ans. (b)
Sol. PowerPoint is used to make presentations/slide shows.
S11. Ans. (d)
Sol. All are memory access mechanism which a CD Player can use.
S12. Ans. (a)
Sol. Each box in a spreadsheet is called a cell.
S13. Ans. (e)
Sol. A toggle key is a key that is used to turn a function on or off, or to switch between two functions.
S14. Ans.(a)
Sol. A biometric device is a type of device that records the unique characteristics such as finger prints because it is impossible to have two different persons with the same fingers prints.
S15. Ans.(c)
Sol. A watermark is a ghost text that is set behind the content of a page.
