In the IBM PC-AT, what do the words AT stand for?

Additional terminals
Advance technology
Applied technology
Advanced terminology E. None of the above

The correct answer is: Advanced Technology.

The IBM PC-AT was released in 1984 and was a significant upgrade to the original IBM PC. It featured a number of new technologies, including a 286 processor, 8087 math coprocessor, and 640KB of RAM. The AT also introduced the AT bus, which became the standard bus for IBM-compatible PCs.

The name “AT” stands for “Advanced Technology”. This was a reference to the new technologies that were included in the PC-AT.

The other options are incorrect.

  • Option A: “Additional terminals” is incorrect because the PC-AT did not support additional terminals.
  • Option B: “Advance technology” is incorrect because this is a vague term that could refer to any number of things.
  • Option C: “Applied technology” is incorrect because this is also a vague term that could refer to any number of things.
  • Option D: “Advanced terminology” is incorrect because this is not a technical term that would be used to describe a computer.
