Computer Hardware and Software Questions and Answers

Answer: B

The largest capacity is the \(10^{8}\) Megabyte hard disk.

Convert all four to bytes, using decimal prefixes (1 KB = \(10^{3}\) bytes, 1 MB = \(10^{6}\), 1 GB = \(10^{9}\), 1 TB = \(10^{12}\)):

\[ \begin{aligned} 10^{10}\ \text{KB} &= 10^{13}\ \text{bytes} \\ 10^{8}\ \text{MB} &= 10^{14}\ \text{bytes} \\ 10^{4}\ \text{GB} &= 10^{13}\ \text{bytes} \\ 10\ \text{TB} &= 10^{13}\ \text{bytes} \end{aligned} \]

Three of the disks hold 10 TB each, while \(10^{8}\) MB is 100 TB, ten times as much.

Answer: C

The most suitable software is a word processor.

A word processor such as Microsoft Word or LibreOffice Writer creates formatted documents with different fonts, colours, styles, tables and images, laid out in pages ready for printing. An annual report is exactly such a document.

A text editor such as Notepad handles plain text without fonts or images. A spreadsheet is for tables of numbers and calculations, and a browser is for viewing web pages.

Answer: C

The operating system is software, not an internal hardware component. The CPU (the processor), the heat sink (which carries heat from the processor to the air) and the network interface card (the board that connects the computer to a network) are all physical parts that sit inside the cabinet of a desktop computer. The operating system, such as Windows or Linux, is a program stored on the drive and loaded into memory.

Answer: A

Tally is accounting application software, used to keep accounts, vouchers, inventory and GST records. MS-Word is a word processor, OpenOffice is an office suite and MS-Access is a database management system, so these three are not accounting software. Tally, which is widely used by Indian businesses, can record vouchers, produce balance sheets and handle GST returns.

Answer: D

Correct answer: The area where all of the processing takes place

The CPU fetches and executes the instructions, which is what processing means. Driving the monitor is the video card's work and regulating power the supply's.

Answer: A

Correct answer: Their protective sleeves

A 5¼ inch diskette has an open media window, so the sleeve is what keeps dust and fingerprints off the recording surface.

Answer: D

Correct answer: 25 pin female parallel connector

On the PC the printer port is a 25-pin female parallel connector; the printer end of the cable is the 36-pin Centronics connector.

Answer: A

Correct answer: Config.sys

BUFFERS is a device and memory setting read by DOS as it loads, so it belongs in CONFIG.SYS. AUTOEXEC.BAT runs afterwards, once the system is already configured.

Answer: B

Correct answer: sound card (or motherboard if sound is integrated with it)

The thin analogue cable carries audio from the drive to the sound card, so that a music CD can be played without the data passing through the bus.

Answer: C

Correct answer: type III

A Type III card is 10.5 mm thick, enough to house a miniature hard disk. Type I at 3.3 mm holds memory and Type II at 5 mm modems and network cards.
