Computer Science

John McCarthy developed LISP in 1958 at MIT specifically for artificial intelligence research, making him the correct answer. The other options are notable computer scientists but not related to LISP's creation.

The primary input device for a computer system is the keyboard, as it allows users to input data and commands directly into the computer. Monitors, speakers, and printers are output devices, not input devices.

Peripheral devices are typically connected to the motherboard, which provides the necessary ports and interfaces for communication with the CPU and other components.

Computers outperform mechanical calculators primarily because of their versatility; they can perform a wide range of tasks beyond simple calculations, unlike mechanical calculators which are limited to arithmetic operations.

The transfer of data in a computer primarily involves physical components such as buses, cables, and ports that move data between devices. Software manages data but does not physically transfer it, so the correct answer is the physical part.

Physical parts of a computer that can be seen and touched are called hardware, while software refers to programs and data that run on the hardware.

The on/off power button is typically located on the side of many devices such as smartphones, tablets, and some laptops, making option C the most accurate choice.

A computer program is written in a programming language that is understood by programmers and then translated into machine code that a computer can understand. Therefore, both statements A and B are valid.

Douglas Engelbart invented the first computer mouse in 1964 in the United States, making option A correct. The other options are notable figures in computing but not related to the invention of the mouse.

A trackball is an input device used to control the cursor on a computer screen by rotating a ball with the fingers or palm. It is not a storage device, output device, or programming language.
