S1. Ans.(c)
Sol. The BIOS is a type of firmware used to perform hardware initialization during the booting process (power-on startup) on IBM PC compatible computers, and to provide runtime services for operating systems and programs.

S2. Ans.(e)
Sol. E-commerce is the buying and selling of goods and services, or the transmitting of funds or data, over an electronic network, primarily the internet. 

S3. Ans.(a)
Sol.  Steps to Turn a picture or a company logo into a watermark. On the Page Layout tab, in the Page Background group, click Watermark. Choose Custom Watermark. Select Picture watermark, and then choose Select Picture. Select the picture that you want, and then choose Insert.

S4. Ans.(b)
Sol. A network packet is a formatted unit of data carried by a packet-switched network. Computer communications links that do not support packets, such as traditional point-to-point telecommunications links, simply transmit data as a bit stream. 

S5. Ans.(b)
Sol. Access time is the time from the start of one storage device access to the time when the next access can be started. Access time consists of latency (the overhead of getting to the right place on the device and preparing to access it) and transfer time.

S6. Ans.(d)
Sol. The CMOS is a computer chip on the motherboard. There is a CMOS battery whihc supplies constsant power to that CMOS chip. Most common effect of CMOS is the time and date setting which will be reset back to the manufactured data if it has been off for a long period of time.

S7. Ans.(c)
Sol.  MIPS (million instructions per second) is a general measure of computing performance and, by implication, the amount of work a larger computer 

S8. Ans.(c)
Sol. Scanners, printers, and speakers are peripheral devices for a computer because they aren't central to the working of the computer itself.

S9. Ans.(a)
Sol. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.

S10. Ans.(b)
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).

S11. Ans.(b)
Sol. Firmware is programming that's written to the read-only memory (ROM) of a computing device.

S12. Ans.(d)
Sol. A computer mouse is an input device that is most often used with a personal computer. Moving a mouse along a flat surface can move the on-screen cursor to different items on the screen. Items can be moved or selected by pressing the mouse buttons (called clicking).

S13. Ans.(c)
Sol. The gigahertz, abbreviated GHz, is a unit of alternating current (AC) or electromagnetic (EM) wave frequency equal to one thousand million hertz (1,000,000,000 Hz).

S14. Ans.(b)
Sol. A GUI is a type of human-computer interface (i.e., a system for people to interact with a computer) that uses windows, icons, pull-down menus and a pointer and that can be manipulated by a mouse (and usually to some extent by a keyboard as well).

S15. Ans.(a)
Sol. A component designed to lower the temperature of an electronic device by dissipating heat into the surrounding air. All modern CPUs require a heat sink.
