Answers:

Ans1. (b)
An instruction cycle is the basic operational process of a computer. It is the process by which a computer retrieves a program instruction from its memory, determines what actions the instruction dictates, and carries out those actions.

Ans2. (a)
A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer's CRT display. It allows the user to point to displayed objects or draw on the screen in a similar way to a touchscreen but with greater positional accuracy.

Ans3. (a)
A scanner is a device that captures images from photographic prints, posters, magazine pages, and similar sources for computer editing and display.

Ans4. (d)
There are two main kinds of semiconductor memory, volatile and non-volatile. Examples of non-volatile memory are flash memory (used as secondary memory) and ROM, PROM, EPROM and EEPROM memory (used for storing firmware such as BIOS). Examples of volatile memory are primary storage, which is typically dynamic random-access memory (DRAM), and fast CPU cache memory, which is typically static random-access memory (SRAM) that is fast but energy-consuming, offering lower memory areal density than DRAM.

Ans5. (a)
Magnetic cores are component of a ROM.

Ans6. (a)
The terms "online" and "offline" have specific meanings in regard to computer technology in which "online" indicates a state of connectivity, while "offline" indicates a disconnected state.

Ans7. (d)
Video Graphics Array (VGA) refers specifically to the display hardware first introduced with the IBM PS/2 line of computers, but through its widespread adoption has also come to mean either an analog computer display standard, the 15-pin D-subminiature VGA connector or the 640x480 resolution itself.

Ans8. (d)
Ctrl + Shift + P is the shortcut key to access the font size tool on font dialog box.

Ans9. (e)
IP, TCP and Gopher all are protocols governing the internet. IP-Internet Protocol, TCP- Transmission Control Protocol

Ans10. (c)
Visual FoxPro is a data-centric, object-oriented, procedural, programming language produced by Microsoft. It is derived from FoxPro (originally known as FoxBASE) which was developed by Fox Software beginning in 1984.
