Under most courses at WGU, history is in textbooks, but is not tested. For this course, it is important to understand the different generations, their era, and what came out of them. You need to know who was utilizing computers due to their size, speed, cost, and user-friendly nature

1. First - Scientific and military applications
   1. Computers were the size of entire rooms
   2. Slow speed and high-power consumption
   3. Example ENIAC and UNIVAC
2. Second - Commercial and Research Purposes
   1. Converted Vaccuum to Transistor
   2. Better than the previous generation on reliability and speed
   3. Example IBM 7090, CDC 1604
3. Third – Business and industries
   1. Compacting multiple transistors into an integrated circuit (IC)
   2. Compact and powerful, higher speed, and less heat production
   3. IBM 360, PDP-8
4. Fourth -User-friendly and GUIs for common user
   1. Microprocessor introduction – CPU onto a single chip
   2. Affordable for personal computers, powerful, GUI, Small in size
   3. Intel 4004, Apple Macintosh
5. Fifth – AI
   1. AI systems capable of performing complex tasks aka natural language processing, image recognition, and autonomous decision making
