In the paired material, which term is linked to the description 'brain of computer'?

• A. Encryption
• B. Central processing unit
• C. Error detection
• D. Asymmetric encryption

Answer: (D)

The term linked to the description “brain of computer” is the central processing unit. The CPU is the component that actually runs programs by fetching instructions from memory, decoding them, and executing them. It coordinates everything the computer does, directing data and control signals to memory and I/O devices, and it uses its control unit and arithmetic logic unit to carry out operations. The other terms are about data security (encryption and asymmetric encryption) or data integrity (error detection), not about carrying out instructions or controlling the computer’s activities.
