Concept:Computer chips are broadly divided into memory chips and processing chips.
Explanation:The two major types of computer chips are the primary memory chip and the microprocessor chip.
A primary memory chip, such as RAM, temporarily stores data and instructions that the computer is currently using.
A microprocessor chip is the brain of the computer, where most calculations and processing operations take place.
An external memory chip is not considered one of the two major internal chip types.
Therefore, the correct choices are a primary memory chip and a microprocessor chip.
Answer:The two major types of computer chips are the primary memory chip and the microprocessor chip, corresponding to options A and C.
