Q81. What does the abbreviation MTBF stand for in reliability engineering?
a) Mean Time Between Failure
b) Mean Time Before Failure
c) Maximum Time Between Failure
d) Maximum Time Before Failure
Show Answer
Correct Answer: a) Mean Time Between Failure
Explanation: MTBF (Mean Time Between Failure) is a metric used to estimate the average time between failures of a mechanical or electronic system during normal system operation. It is calculated by dividing the total number of operational hours by the number of failures in that period. MTBF is typically measured in hours and is used to assess the reliability and availability of equipment, helping businesses understand the performance of their assets.
Q82. What does the abbreviation MICR stand for in banking technology?
a) Magnetic Ink Character Recognition
b) Magnetic Image Character Recognition
c) Magnetic Ink Code Recognition
d) Magnetic Image Code Recognition
Show Answer
Correct Answer: a) Magnetic Ink Character Recognition
Explanation: MICR (Magnetic Ink Character Recognition) is a technology used primarily to identify and process checks. The MICR line on a check is printed using magnetic ink or toner, which allows a computer to read the MICR numbers, even if they have been covered by marks or writing. MICR is designed to enhance security and minimize losses caused by some types of fraud, such as counterfeit checks produced using color photocopying machines.
Q83. What does the abbreviation MMC stand for in digital storage?
a) Multimedia Card
b) Memory Management Card
c) Multi-Memory Card
d) Memory Module Card
Show Answer
Correct Answer: a) Multimedia Card
Explanation: MMC (Multimedia Card) is a flash memory card standard used for solid-state storage. Introduced in 1997 by SanDisk and Siemens, MMC is based on a surface-contact low pin-count serial interface using a single memory stack substrate assembly, making it much smaller than earlier systems based on high pin-count parallel interfaces such as CompactFlash.
Q84. What does the abbreviation MBR stand for in computer technology?
a) Memory Buffer Register
b) Memory Base Register
c) Memory Block Register
d) Memory Bandwidth Register
Show Answer
Correct Answer: a) Memory Buffer Register
Explanation: MBR (Memory Buffer Register) is a register in a computer’s CPU that stores the data being transferred to and from the immediate access storage. It acts as a buffer, allowing the processor and memory units to act independently without being affected by minor differences in operation.
Q85. What does the abbreviation MNP stand for in computer networking?
a) Microcom Network Protocol
b) Memory Network Protocol
c) Modem Network Protocol
d) Media Network Protocol
Show Answer
Correct Answer: a) Microcom Network Protocol
Explanation: MNP (Microcom Networking Protocol) is a communication protocol initially developed by Microcom Inc for error corrections and compressions. MNP corrects modifications introduced in data during transmissions by telephone line interference and offers various levels for data corrections and compression.
Q86. What does the abbreviation MB stand for in computer storage?
a) Mega Bytes
b) Mega Bits
c) Mega Bandwidth
d) Mega Base
Show Answer
Correct Answer: a) Mega Bytes
Explanation: MB (Mega Bytes) stands for 1 million bytes of computer storage or memory. It is a unit of digital information used to quantify the size of data in computing.
Q87. What does the abbreviation MS-DOS stand for in computer operating systems?
a) Microsoft Disk Operating System
b) Microsoft Data Operating System
c) Microsoft Device Operating System
d) Microsoft Drive Operating System
Show Answer
Correct Answer: a) Microsoft Disk Operating System
