Computer fundamental MCQ Questions and answers- Technical Aptitude

A random-access data storage device which gives rapid access to data is Disk storage unit. A disk drive is a device implementing such a storage mechanism. Notable types are the hard disk drive (HDD) containing a non-removable disk, the floppy disk drive (FDD) and its removable floppy disk, and various optical disc drives (ODD) and associated optical disc media.

A card on the top of pack of cards containing information about the cards in the pack is Reader card. A memory card reader is a device used for communication with a smart card or a memory card. A magnetic card reader is a device used to read magnetic stripe cards, such as credit cards.

VRAM (video RAM) is a reference to any type of random access memory (RAM) used to store image data for a computer display. All types of VRAM are special arrangements of dynamic RAM (DRAM). VRAM is a buffer between the computer processor and the display, and is often called the frame buffer.

A type of core store that has a lower access time than the devices used for working store in the same processor is known as fast core.

A floppy disk, also known as a floppy, diskette, or simply disk, is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic enclosure lined with fabric that removes dust particles. Floppy disks are read and written by a floppy disk drive (FDD).

Conversion of a hexadecimal number (4E)₁₆ to binary number is (1001110)₂
(4E)₁₆ = (1001110)₂
Because 4 = 100
E in hexadecimal number is = 14
And 14 = 1110
Thus answer is = 1001110

A device that transmits messages in verbal form is Audio response unit. An Audio Response Unit is an output device that provides a spoken response to digital inquiries from a telephone or other device. For example, Press 1 to hear this information again; Press 2 to hear more options. It is also known by the generic name audiotex.

A standard tape recorder used to save or load computer information is known as Cassette drive. To store data on digital cassettes, read or write head moves quickly. This quick movement of the reading/write head enables to maintain speed which would be enough to maintain the bits at a manageable size.

Memory is a component of a computer is responsible for the transient or temporary storage used by the CPU. Memory is the process of taking in information from the world around us, processing it, storing it and later recalling that information, sometimes many years later. Human memory is often likened to that of a computer memory system or a filing cabinet.

In printing, DPI (dots per inch) refers to the output resolution of a printer or imagesetter, and PPI (pixels per inch) refers to the input resolution of a photograph or image. DPI refers to the physical dot density of an image when it is reproduced as a real physical entity, for example printed onto paper.
