Classification of computer by age of technology?

Answer 1

1. Vacuum tube
2. Discrete transistor (a few used magnetic amplifiers)
3. Integrated circuit (both hybrids and monolithics)
4. Microprocessors (both multi-chip chipsets and single chip)
5. Multi-core microprocessors and system on a chipprocessors

First and second generation computers usually were separated into business and scientific product lines, with completely different architectures optimized for market application. Most third generation and beyond used a common general purpose architecture regardless of market application.

System on a chip processors have one or more processor cores plus most of the I/O hardware normally on a motherboard in a single chip. This eliminates most of the need for a motherboard.
