note!Answer: A) DPI
Printing resolution and print quality are measured in dots per inch (DPI).

note!Answer: D) Based on optical and magnetic technology
A magneto-optical (MO) disk combines optical and magnetic technologies.

note!Answer: B) LCD monitor
In traditional computer-fundamentals MCQs, an LCD monitor is often considered to provide better output quality than a CRT monitor because it produces sharper images, uses less power, and has less flicker.

note!Answer: A) Translator
A translator is the general term for software that converts source code into machine code or another target form. A compiler, assembler, and interpreter are types of language translators.

note!Answer: D) Hexadecimal
Hexadecimal uses digits 0-9 and letters A-F to represent numbers.

note!Answer: C) Digitizer
A digitizer is an input device used to convert maps, drawings, and geographical information from paper into digital data. It is commonly associated with geographical mapping and GIS (Geographic Information Systems).

note!Answer: B) 8 inch
The first floppy disk introduced by IBM in 1971 was 8 inches in size.

note!Answer: A) VDU
A monitor is also called a VDU (Visual Display Unit).

note!Answer: A) Double data rate
DDR stands for Double Data Rate, a memory technology that transfers data on both the rising and falling edges of the clock.

note!Answer: D) Both a and b
The ROM BIOS performs POST and handles the boot start-up process, so both a and b are functions.

note!Answer: B) MICR
MICR (Magnetic Ink Character Recognition) reads the magnetic ink characters on cheques, so banks use it.

note!Answer: C) 18
A 1.44 MB high density floppy disk has 18 sectors per track.

note!Answer: A) Decoders
A decoder converts coded input signals into specific output signals. In basic computer-fundamentals MCQs, decoders are associated with converting coded signals into usable outputs.

note!Answer: B) Biochip
A biochip is associated with advanced technology that combines biological and electronic or computing-related functions. In older computer-fundamentals MCQs, it may be described as a chip for future high-performance computing.

note!Answer: A) Personal Digital Assistant
PDA stands for Personal Digital Assistant, a handheld personal organizer device.

note!Answer: C) Resolution
Printer output quality is primarily measured by its resolution, usually expressed in DPI (dots per inch). A higher DPI generally produces sharper and more detailed prints.

note!Answer: A) Transmit data faster
A wider data bus can transfer more bits of data at once. This increases the amount of data transferred per bus cycle and can improve data-transfer speed.

note!Answer: B) 1.44MB
A 2HD 3.5-inch floppy disk stores 1.44 MB (megabytes).

note!Answer: B) Burning
Data is written to a CD-ROM by burning it with a laser.

note!Answer: C) American
In the traditional computer-fundamentals MCQ context, the system date is commonly associated with the American date format, MM/DD/YYYY (Month/Day/Year).
