Digital Systems Fundamentals Practice Quiz…

Q: What number system is used in digital systems?

Binary — Digital systems use the binary number system (base-2) to represent and process data.

Q: Which component of a digital system performs arithmetic and logical operations?

ALU — The Arithmetic and Logic Unit (ALU) within the CPU carries out arithmetic and logical operations.

Q: What is the primary function of the Control Unit (CU)?

Coordinates the operation of other components and generates clock signals — The Control Unit coordinates the operation of other components and generates timing signals within the CPU.

Q: Which type of memory is volatile?

RAM — RAM (Random Access Memory) is volatile, meaning its contents are lost when power is removed.

Q: Which of the following is an input device?

Keyboard — A keyboard is used to input data into a digital system.

Q: Which of the following is an output device?

Printer — A printer is used to display processed data.

Q: What is the primary function of a logic gate?

Perform logical operations — Logic gates perform fundamental logical operations such as AND, OR, and NOT.

Q: What does a power supply unit typically convert?

AC to DC — A power supply typically converts AC (alternating current) to DC (direct current) and regulates the voltage.

Q: What is the collective name for the channels that allow data transmission between system components?

Bus system — The bus system (data bus, address bus, control bus) enables data transmission.

Q: Which gate outputs a '1' only when both inputs are '1'?

AND gate — An AND gate outputs a '1' only if all its inputs are '1'.
