2. The main idea of the second paragraph is the comparison between microcomputers and personal computers. It is stated that not all computers are personal computers and that microcomputers can be dedicated to specific tasks, while personal computers are stand-alone computers with a wide array of capabilities.
3. The main idea of the third paragraph is the evolution and growth of personal computers. It mentions that the first generation of true personal computers, with eight-bit microprocessors, came on the market between 1977 and 1981. It also notes that the capacity of microprocessors has increased over time, with the availability of 16-bit and 32-bit microprocessor chips.
To summarize:
1. The main idea of the first paragraph is the accessibility of personal computers for individuals without technical backgrounds.
2. The main idea of the second paragraph is the comparison between microcomputers and personal computers.
3. The main idea of the third paragraph is the evolution and growth of personal computers.
