Q1. Difference between lathe and milling machine Ans- Lathe machine is a single cutting tool and milling machine is a multiple cutting tool.
Ans. 
Lathe machine rotates the workpiece while the cutting tool remains stationary, while milling machine rotates the cutting tool and workpiece simultaneously.
• Lathe machine is used for cylindrical workpieces, while milling machine is used for flat or irregularly shaped workpieces.

• Lathe machine can only produce symmetrical shapes, while milling machine can produce both symmetrical and asymmetrical shapes.

• Lathe machine is si...read more

Q1. Differentiate between RISC and CISC
Ans. 
RISC stands for Reduced Instruction Set Computing and CISC stands for Complex Instruction Set Computing.
• RISC processors have a smaller set of simple instructions, while CISC processors have a larger set of complex instructions.

• RISC processors typically execute instructions in one clock cycle, while CISC processors may require multiple clock cycles.

• RISC processors rely on optimizing compilers for performance, while CISC...read more

Q2. Define and differentiate interpreter and compiler
Ans. 
Interpreter translates code line by line while compiler translates entire code at once.
• Interpreter: translates code line by line, slower execution, easier debugging (e.g. Python)

Q2. How ADC(Analog to Digital Converter) works?
Ans. 
ADC converts analog signals into digital data by sampling the input signal at regular intervals.
• ADC samples the input signal at regular intervals

• It quantizes the sampled values into discrete digital values

• The resolution of ADC determines the number of possible digital values

• Common types of ADC include successive approximation ADC and delta-sigma ADC
