Sample WBBSE Madhyamik Computer Application (Optional) Practice Questions

Try these sample questions to test your WBBSE Madhyamik Computer Application (Optional) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which component of the CPU is responsible for executing basic arithmetic calculations and bitwise logical comparisons?

A.Arithmetic Logic Unit (ALU)

B.Control Unit (CU)

C.Register File

D.Cache Memory

Explanation: The Arithmetic Logic Unit (ALU) is the CPU sub-component that carries out mathematical operations (such as addition and subtraction) and logical comparisons (such as AND, OR, and equality tests).

2Which memory type is small, extremely fast, volatile, and positioned directly between the CPU registers and main RAM to reduce access time?

A.Flash Drive Memory

B.Cache Memory

C.Read-Only Memory (ROM)

D.Hard Disk Memory

Explanation: Cache memory is a high-speed volatile SRAM buffer built into or close to the CPU that holds frequently used data and instructions, dramatically lowering access latency compared to main RAM.

3What is the binary equivalent of the decimal number 25?

A.11010

B.10111

C.11001

D.11100

Explanation: Converting 25 to binary via repeated division by 2: 25 / 2 = 12 (rem 1), 12 / 2 = 6 (rem 0), 6 / 2 = 3 (rem 0), 3 / 2 = 1 (rem 1), 1 / 2 = 0 (rem 1). Reading remainders bottom-up gives 11001.

4Which number system utilizes base 16 and incorporates symbols 0-9 alongside letters A through F?

A.Binary System

B.Octal System

C.Decimal System

D.Hexadecimal System

Explanation: The Hexadecimal number system uses base 16. It employs digits 0-9 for values 0-9 and letters A-F for values 10-15, providing a compact representation of binary data.

5What is the smallest basic unit of digital information stored in a computer system?

A.Bit

B.Byte

C.Nibble

D.Kilobyte

Explanation: A bit (binary digit) represents the smallest atomic unit of digital data, holding a value of either 0 or 1.

6Which variation of Read-Only Memory (ROM) can be completely erased by exposing its chip to intense ultraviolet (UV) light?

A.PROM

B.EPROM

C.EEPROM

D.Mask ROM

Explanation: EPROM (Erasable Programmable Read-Only Memory) can be erased by exposing the transparent quartz window on top of its package to ultraviolet light, allowing it to be rewritten.

7What is the 6-bit binary equivalent of the octal number (37)8?

A.010111

B.011101

C.011111

D.100111

Explanation: Each octal digit converts to a 3-bit binary equivalent: 3 = 011 and 7 = 111. Combining them yields (011111)2.

8In standard binary computing capacity measurement (2^20 bytes), how many bytes are exactly equal to 1 Megabyte (MB)?

A.1,000,000 bytes

B.1,024,000 bytes

C.1,048,000 bytes

D.1,048,576 bytes

Explanation: In traditional binary memory addressing, 1 KB = 2^10 = 1,024 bytes and 1 MB = 1,024 KB = 1,024 x 1,024 = 1,048,576 bytes.

9Which input device captures visual images of printed documents or photos and converts them into digital graphic files?

A.Optical Scanner

B.Plotter

C.Barcode Reader

D.Dot Matrix Printer

Explanation: An Optical Scanner shines light onto physical paper documents and uses optical sensors to convert printed text and images into digital raster image files.

10Which component on a motherboard maintains the system real-time clock and hardware configuration settings when the computer is shut down?

A.CPU Fan

B.CMOS Battery

C.Power Supply Unit (PSU)

D.Expansion Bus

Explanation: The Complementary Metal-Oxide-Semiconductor (CMOS) battery provides continuous low-voltage power to the motherboard's CMOS chip, keeping the system clock running and preserving BIOS settings when main power is disconnected.

About the WBBSE Madhyamik Computer Application (Optional) Exam

The WBBSE Madhyamik Computer Application examination tests Class 10 students on fundamental computer concepts, hardware and software components, operating system operations, word processing (MS Word), spreadsheet calculations (MS Excel), presentations (MS PowerPoint), web page authoring using HTML, digital logic gates, binary arithmetic, and computer networking & Internet protocols. Note: This practice question bank is an English-language MCQ study adaptation for the WBBSE Madhyamik Optional Computer Application examination, designed to reinforce core computing concepts, syntax, formulas, and logic operations.

Assessment

Madhyamik Optional Elective - Computer Application: 2-hour-45-minute theory paper in the Optional Elective sitting, plus a school-conducted practical examination.

Time Limit

Theory 2 hours 45 minutes; practical examination conducted by the individual school

Passing Score

WBBSE reports each subject on a seven-point grade scale: AA 90-100, A+ 80-89, A 60-79, B+ 45-59, B 35-44, C 25-34 (marginal pass) and D below 25 (disqualified). Grade C is therefore the minimum subject grade and a D in any compulsory subject makes the overall result unsuccessful. Division bands are separate: 1st division 480+, 2nd 360+, 3rd 272+ out of 800.

Exam Fee

WBBSE does not publish a single per-candidate examination fee with the Madhyamik routine. Enrolment is made by the school online through wbbsedata.com within the Board's registration window, and the amount payable is set by the Board's enrolment circular for that session. Confirm the current figure with your school or the Board's notification rather than relying on a quoted estimate. (West Bengal Board of Secondary Education (WBBSE))
