Question

which definition best describes a computer?
a machine with a brain and emotions
a machine that stores and processes data
a device that collects viruses and dust
a device that was invented to be smarter than man

Explanation:

To determine the best definition of a computer, we analyze each option:

• "A machine with a brain and emotions" is incorrect because computers don't have biological brains or emotions.
• "A machine that stores and processes data" aligns with the fundamental function of a computer, as computers are designed to store, retrieve, and manipulate data.
• "A device that collects viruses and dust" is incorrect; while computers can get viruses (software) or accumulate dust (hardware), this is not their primary function.
• "A device that was invented to be smarter than man" is incorrect, as the purpose of computers is to assist with tasks, not to surpass human intelligence in a general sense, and this is not a standard definition.

Answer:

B. A machine that stores and processes data
