What is motherboard ?
Answer: B
Correct answer: A circuit board which connects all the elements

Word "INTERPRETER" is related to ?
Answer: C
Correct answer: Programming Languages
An interpreter takes a program in a high-level language and executes it statement by statement, translating each one as it reaches it rather than producing a machine-code file first. That makes it slower than a compiled program but easier to test, since a change can be run at once.

Answer: C
Correct answer: Babbage

Which part interprets program instructions and initiate control operations
Answer: D
Correct answer: Control unit
The control unit fetches each instruction from memory, decodes it to work out what is required, and then issues the timing and control signals that make the other units carry it out. The logic unit performs the arithmetic and comparisons it is told to, storage holds data, and input merely delivers it.
