Q4. What is AND gate
Ans. 
An AND gate is a logic gate that outputs a high signal only when all of its inputs are high.
• AND gate is a basic logic gate used in digital circuits.

• It has two or more inputs and one output.

• The output of an AND gate is true only when all of its inputs are true.

• It follows the truth table: 0 AND 0 = 0, 0 AND 1 = 0, 1 AND 0 = 0, 1 AND 1 = 1.

• AND gates are commonly used in computer processors, memory units, and other digital

Q5. What is NOR gate
Ans. 
A NOR gate is a logic gate that produces an output of true only when all of its inputs are false.
• NOR gate is a type of logic gate that performs the logical NOR operation.

• It has two or more inputs and one output.

• The output of a NOR gate is true (or high) only when all of its inputs are false (or low).

• It is the complement of the OR gate.

• The truth table for a NOR gate is: 0 NOR 0 = 1, 0 NOR 1 = 0, 1 NOR 0 = 0, 1 NOR 1 = 0...read more

Q6. What is basic gate
Ans. 
A basic gate is a fundamental building block of digital circuits that performs a specific logical operation.
• Basic gates include AND, OR, NOT, NAND, NOR, and XOR gates.

• AND gate outputs true only when all inputs are true.

• OR gate outputs true when at least one input is true.

• NOT gate inverts the input signal.

• NAND gate outputs the negation of the AND gate.

• NOR gate outputs the negation of the OR gate.

• XOR gate outputs true wh

Q1. A Water cement ratio
Ans. 
Water cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
• Water cement ratio is a crucial factor in determining the strength and durability of concrete.

• A lower water cement ratio results in stronger and more durable concrete.

• Typical water cement ratios range from 0.4 to 0.6 for normal strength concrete.

• For high strength concrete, water cement ratios can be as low as 0.25.
