What was the clock speed of the original IBM PC?

Less than 5 MHz
10 MHz
8 MHz
Just over 16 MHz

The correct answer is: C. 8 MHz

The original IBM PC was released in 1981 with an 8 MHz Intel 8088 processor. This was a significant increase in speed over the previous generation of personal computers, which typically had processors running at 4.77 MHz or less. The 8 MHz clock speed allowed the IBM PC to run faster and more complex programs than its predecessors.

The other options are incorrect:

  • Option A is incorrect because the original IBM PC had an 8 MHz clock speed, which is greater than 5 MHz.
  • Option B is incorrect because the original IBM PC had an 8 MHz clock speed, 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z"/> Subscribe on YouTube
which is less than 10 MHz.
  • Option D is incorrect because the original IBM PC had an 8 MHz clock speed, which is less than just over 16 MHz.
