Question 4 Explanation:
Half Adder (A) – (IV): A Half Adder is a 2-bit addition circuit that adds two binary digits and produces a sum and a carry output.
Decoder (B) – (I): A decoder is a combinational logic circuit that has n inputs and produces 2^n output lines. It converts binary data into a specific output.
Register (C) – (II): A register is a small, fast storage location in a CPU used to store intermediate data, often during calculations or temporary storage.
Main memory (D) – (III): Main memory, also known as RAM, is used to store the program and data at runtime while the CPU is executing tasks.
Decoder (B) – (I): A decoder is a combinational logic circuit that has n inputs and produces 2^n output lines. It converts binary data into a specific output.
Register (C) – (II): A register is a small, fast storage location in a CPU used to store intermediate data, often during calculations or temporary storage.
Main memory (D) – (III): Main memory, also known as RAM, is used to store the program and data at runtime while the CPU is executing tasks.
