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, 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.
