Those microcomputers which have the same operating characteristics as the IBM microcomputers are called IBM

duplicates
clones
copies
look alikes E. None of the above

The correct answer is: B. clones

A clone is a computer that is designed to be compatible with another computer, usually a more popular model. Clones are often less expensive than the original model, and they can be used with the same software and peripherals.

IBM clones are microcomputers that are designed to be compatible with IBM personal computers. They were first introduced in the early 1980s, and they quickly became popular due to their lower cost than IBM PCs. IBM clones are still available today, and they are often used in businesses and schools.

The other options are incorrect because they do not accurately describe IBM clones.

  • Duplicates are exact copies of something. IBM clones are not exact copies of IBM PCs, but they are designed to be compatible with them.
  • Copies are similar to something, but they are not exactly the same. IBM clones are similar to IBM PCs, but they are not exactly the same.
  • Look-alikes are things that look similar to each other, but they are not the same. IBM clones look similar to IBM PCs, but they are not the same.
