Konti sorol tomo songkha poddhoti(পদ্ধতি)?
Correct Answer
C. Bainary
Explanation
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.

Hexadicimel 'C' ar bainary koto?
Correct Answer
B. 1100
Explanation
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.

chittroti kon gate nirdes kora?
Correct Answer
D. OR gate
Explanation
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.

Bisuddho silikon ba jermanium____
i) uttom poribahok.
ii) uttom ontorok.
iii) muktto electron bihin thaka.

Konti moulik gate?
Correct Answer
A. AND
Explanation
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.
