Which of the following was NOT the first to develop a microprocessor?
Show answer & explanation
Microsoft is a software company founded in 1975 and has never developed microprocessors as a primary business. Intel developed the 4004 (1971), Texas Instruments developed the TMS1000 (1974), and Garrett AiResearch contributed to early microprocessor development. Microsoft's core business is operating systems and application software, making it the only non-microprocessor developer among the options.
Step-by-step Derivation:
Historical timeline of microprocessor development:
- Intel 4004 (1971) - First commercially available microprocessor, developed by Intel
- Texas Instruments TMS1000 (1974) - Early microprocessor series
- Garrett AiResearch - Contributed to aerospace and early computing systems
- Microsoft (1975) - Software company, never a microprocessor manufacturer
The question asks which was NOT the first to develop a microprocessor. While Intel was technically first (4004, 1971), the question structure implies identifying the entity that had no role in microprocessor development. Microsoft is the only software company in the list with no microprocessor development history, making it the correct answer to this negation-based question.
