9 of 18
which definition best describes a computer?
a machine that stores and processes data
a machine with a brain and emotions
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:

• Option A: Computers are known to store (e.g., in hard drives, memory) and process (e.g., via the CPU) data, which aligns with their core function.
• Option B: Computers do not have a "brain" or emotions as they are machines without biological or emotional capabilities.
• Option C: Computers do not collect viruses (they can be infected by them, but that's not their function) or dust (dust is a physical contaminant, not related to their purpose).
• Option D: Computers are tools created to assist humans, not to be "smarter" in a comparative sense, and this is not a standard definition.

Answer:

A. A machine that stores and processes data
