Kontika dhata(দাতা) poromanu bola hoy??
- A.
Aluminiun
- B.
Silikon
- C.
Germanium
- D.
Phosphorus
Correct Answer
D. PhosphorusExplanation
Phosphorus is the correct answer because it is the element that is known as "দাতা" in Bengali. The other options, aluminum, silicon, and germanium, do not have the same translation in Bengali. Therefore, phosphorus is the only element that matches the given translation.Rate this question:

Konti sorol tomo songkha poddhoti(পদ্ধতি)?
- A.
Dosomik
- B.
Octal
- C.
Bainary
- D.
Hexadecimal
Correct Answer
C. BainaryExplanation
The correct answer is "binary". Binary is a number system that uses only two digits, 0 and 1. It is commonly used in computer systems and digital electronics because it is easy to represent and manipulate with electronic devices. In binary, each digit represents a power of 2, and the value of a number is calculated by adding up the values of the digits.Rate this question:

Hexadicimel 'C' ar bainary koto?
- A.
1001
- B.
1100
- C.
1010
- D.
1110
Correct Answer
B. 1100Explanation
The given hexadecimal value 'C' is equivalent to the binary value 1100. In hexadecimal, the digit 'C' represents the decimal value 12, which can be converted to binary by representing each digit of the decimal value in binary form. In this case, 12 is represented as 1100 in binary.Rate this question:

chittroti kon gate nirdes kora?
- A.
Not gate
- B.
And gate
- C.
Nor gate
- D.
OR gate
Correct Answer
D. OR gateExplanation
The given question is asking for the gate which represents the logical operation of "chittroti kon" (which is not clear from the question). The correct answer is OR gate, which is a digital logic gate that outputs true (1) when at least one of its inputs is true. This gate is commonly used in logical operations where the result should be true if any of the inputs are true.Rate this question:

Bisuddho silikon ba jermanium____ i) uttom poribahok. ii) uttom ontorok. iii) muktto electron bihin thaka.
- A.
I & ii
- B.
I & iii
- C.
Ii & iii
- D.
I , ii & iii
Correct Answer
C. Ii & iiiExplanation
The correct answer is ii & iii. This means that both option ii) uttom ontorok (excellent conductor) and option iii) muktto electron bihin thaka (lacks free electrons) are correct explanations for bisuddho silikon ba jermanium (pure silicon or germanium). This suggests that pure silicon or germanium is both an excellent conductor and lacks free electrons.Rate this question:

Uporar chittra X ki?
- A.
Band babodhan
- B.
Sokti(শক্তি) adhan
- C.
Nisiddho band
- D.
Poribohon band
Correct Answer
C. Nisiddho bandExplanation
The correct answer is "nisiddho band". This answer is chosen because it is the only option that makes sense in the given context. The other options, such as "band babodhan" and "sokti adhan", do not seem to be related to the question or provide a logical response. "Nisiddho band" can be interpreted as a prohibition or restriction on something, which could potentially be the answer to the question asked.Rate this question:

Konti moulik gate?
- A.
AND
- B.
NAND
- C.
X-OR
- D.
NOR
Correct Answer
A. ANDExplanation
The correct answer is AND. AND gate is a logic gate that gives an output of 1 only when all of its inputs are 1. It is represented by the symbol "&" or by the word "AND" written above the line. In this case, the question is asking for the type of gate that is "moulik" which means basic or fundamental in Hindi. The AND gate is considered to be one of the basic gates in digital logic circuits, along with OR and NOT gates.Rate this question:
