Q91
In basic computer hardware numbering systems, what is the exact hexadecimal character representation for the decimal value 14?
C
D
E
F
Explanation
The hexadecimal system uses base-16 tracking. The numbers 0 to 9 are mapped identically, while values 10, 11, 12, 13, 14, and 15 are represented by characters A, B, C, D, E, and F respectively.
Q92
Which type of device driver component or software wrapper functions natively to parse high-level graphics primitives into raster pixel grids for physical display units?
Network Interface stack
Display Driver engine
Audio codec encoder
Serial bus link script
Explanation
A Display Driver or Graphics Card engine interfaces natively between the OS windowing loops and specialized video hardware chips to convert geometric coordinates into raster frames.
Q93
What critical diagnostic routine is natively executed by the system BIOS firmware inside the motherboard chips immediately upon turning on a hard-powered computer?
Disk defragmentation check
Power-On Self-Test (POST)
Virtual memory mapping optimization
Network handshake initialization
Explanation
The Power-On Self-Test (POST) is a built-in diagnostic program that systematically checks the integrity of vital hardware components like the CPU, RAM registers, and system storage controllers before system loading begins.
Q94
Which hardware architecture component handles direct binary calculation loops for floating-point mathematical computations when the primary processor lacks integrated numeric logic subunits natively?
Interrupt Controller block
Math Coprocessor (FPU)
DMA channel bridge
Graphics raster pipeline
Explanation
A Math Coprocessor (or Floating-Point Unit, FPU) is a specialized hardware subunit designed to offload highly complex fractional calculations and decimal exponent tracks from the main processor core pipelines.
Q95
Which measurement unit represents the base storage capacity parameter containing exactly 1024 Petabytes (PB) inside standardized binary processing layouts?
1 Terabyte (TB)
1 Exabyte (EB)
1 Zettabyte (ZB)
1 Yottabyte (YB)
Explanation
In computer systems tracking high-end binary data thresholds, 1 Exabyte (EB) is mathematically defined as exactly 1024 Petabytes (PB).
Q96
In basic computer hardware numbering frameworks, what is the exact decimal equivalent represented by the hexadecimal character 'D'?
11
12
13
14
Explanation
The hexadecimal number system utilizes base-16 tracking. The characters A through F cleanly map to decimal values 10 through 15 respectively (A=10, B=11, C=12, D=13, E=14, F=15).
Q97
Which type of computer input peripheral is specifically designed to read alpha-numeric characters printed in a special magnetizable ink layer natively used on bank cheques?
Optical Mark Reader (OMR)
Magnetic Ink Character Reader (MICR)
Optical Character Recognition (OCR) scanner
Bar Code Reader grid
Explanation
MICR (Magnetic Ink Character Recognition) readers detect the unique magnetic field signatures of characters printed with magnetizable iron oxide ink, widely utilized natively across financial banking systems for sorting cheques.
Q98
What is the primary technical reason why Static RAM (SRAM) exhibits significantly faster access speeds compared to Dynamic RAM (DRAM) setups natively?
SRAM utilizes transistor flip-flops that maintain state continuously without needing periodic refresh cycles
SRAM stores bits as magnetic field variations across an optical lens array
SRAM relies entirely on serial subterranean thermal routing pipelines
SRAM completely bypasses the execution synchronization clock pulses generated by the CU
Explanation
SRAM uses flip-flops consisting of multiple transistors to store each data bit continuously without needing periodic electrical refreshing loops, unlike DRAM which relies on capacitors that continuously leak charge and mandate refresh cycles.
Q99
Which type of basic computing peripheral device functions natively as an impact printer by pressing an embossed wheel character face directly onto an inked ribbon matrix?
Thermal sublimation plotter
Daisy Wheel Printer
Electrostatic drum engine
Piezoelectric inkjet nozzle array
Explanation
A Daisy Wheel Printer is an early type of impact printer that produces high-quality letter text using an embossed plastic or metal wheel mechanism striking against an ink ribbon, analogous to a typewriter.
Q100
Which fundamental basic computer interface metric parameter tracks the absolute number of pixels displayed horizontally and vertically across a monitoring screen?
Dot pitch frequency interval
Screen Resolution
Aspect ratio scale loop
Refresh rate cadence tracking
Explanation
Screen Resolution determines the clarity and density of displayed content by defining total dimensions in pixel grids (such as 1920 × 1080 layouts natively).
