I learned about four inventions this week and they were unix,  microprocessor, video game console, VHS and VCR. First, I learned about unix. Thompson, born in New Orleans, in 1943, and Ritchie, born in New York, in 1941, were the last of Bell Labs, and invented unix together in 1969. Unix is a multi-user computer operating system that does just one thing: input and output. It provided software at a potential fee for educational use, by running on inexpensive hardware, and by being easy to adapt and move to different machines.

Second, I learned the microprocessor. Robert Noyce was the founder of Intel. Busicom asked Intel to build a processor for their calculator in 1969. Federico Faggin is an Italian-American physicist, engineer, inventor, and entrepreneur, who was the inventor of the microprocessor. The Microprocessor is an integrated circuit that contains all the functions of a central processing unit of a computer. Computer codes are zeros and ones. The microprocessor enabled personal computing by allowing for more accessible devices with smaller footprints.

Third,  I learned about the video game console. Ralph Baer, born in Germany, in 1922, ascended the electronics industry and began working on TV projects for the military in the 1950s. A video game console is an electronic device that outputs a video signal or image to display a video game that can be played with a game controller. SNES and Genesis battled for dominance in the 1990s and Nintendo attempted a failed partnership with Sony.
Finally, I learned about VHS and VHR. The first VHRs were released to the commercial industry in 1956 and the JVC company wanted to develop records for consumers. VCR (Video Cassette Recorder) is a video recorder is an electromechanical device that records analog audio and analog video from broadcast television. VHS (Video Home System) is a standard for consumer-level analog video recording on tape cassettes. VHS tapes and VCRs enabled families everywhere to gather around their televisions and watch home videos, movies, and shows on the format.
