The power supply unit (PSU) connects to the motherboard and provides electrical power to various components of the computer. The CPU and RAM are components that receive power but do not supply it, and 'None of these' is incorrect.

An interpreter translates and executes a program one instruction at a time into machine language, unlike a compiler which translates the entire program at once. Therefore, the correct answer is Interpreter.

Automation uses information systems to perform activities more cheaply, quickly, accurately, and consistently by reducing human intervention and errors.

The numeric keypad is a part of the keyboard used for entering numbers quickly. Therefore, 'Numeric Pad is in Keyboard' is correct.

Programs that control the hardware of a computer are called drivers. They act as intermediaries between the operating system and hardware devices, enabling communication and proper functioning.

Guido van Rossum created the Python programming language and released it in 1991. The other options are creators of different programming languages: James Gosling (Java), Dennis Ritchie (C), and Bjarne Stroustrup (C++).

Intelligence is a key characteristic that distinguishes humans from computers, as humans can think, reason, and understand context, whereas computers operate based on programmed instructions without true understanding.

Dennis Ritchie developed the C programming language in 1972 at Bell Labs, making option B the correct answer. The other options are notable figures in computing but unrelated to the creation of C.

A computer at home can be used for multiple purposes including record keeping, watching movies and games, and making budgets, so the correct answer is 'All of these'.

An input device is used to enter data into a computer, such as a keyboard or mouse. Output devices display or present data from the computer, so they do not enter data.
