There are two sets given below. Set-I specifies the IT related acronyms, while Set-II indicates their meanings. Match the two and give your answer by selecting the appropriate code.
Set-I (Acronyms) Set-II (Meanings) (a) DPI (Dots Per Inch) (i) Measures resolution of a laser printer. (b) CRT (Catdode Ray Tube) (iii) A type of computer monitor. (c) NIC (Network Interface Card) (iv) Enables a computer to connect to other computers. (d) CD-ROM (Compact Disc Read-Only Memory) (ii) An example of read-only storage.
(a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)
To solve the problem of matching the acronyms with their correct meanings, we need to understand each term listed in Set-I and how it corresponds to the explanations in Set-II. This is a basic knowledge-based question often seen in exams to assess familiarity with common ICT terminology.
-
DPI (Dots Per Inch): This measures the resolution of various devices such as printers and monitors. It quantifies how many individual dots can be placed in a line within the span of one inch. Therefore,
(a) DPIcorresponds to(i)"Measures resolution of a laser printer." -
CRT (Cathode Ray Tube): This is a technology used in traditional computer monitors and televisions. A CRT consists of one or more electron guns, and a phosphorescent screen is used in older models of screens. So,
(b) CRTmatches with(iii)"A type of computer monitor." -
NIC (Network Interface Card): This is a hardware component that allows a computer to connect to a network. It implements the hardware level of the OSI model. Hence,
(c) NICsuits with(iv)"Enables a computer to connect to other computers." -
CD-ROM (Compact Disc Read-Only Memory): This is a type of optical disc capable of storing data and is read but not written to by a computer. Therefore,
(d) CD-ROMfits with(ii)"An example of read-only storage."
By analyzing each acronym and its corresponding meaning, we conclude that the correct matches are:
- (a)-(i)
- (b)-(iii)
- (c)-(iv)
- (d)-(ii)
Therefore, the correct option is (a)-(i), (b)-(iii), (c)-(iv), (d)-(ii).
