The Unshakable Foundation of Computer Science
New technology is developed every day; so much so that it seems like as soon as we upgrade, a bigger and better version is released. Despite the fact that we see technologies come and go, it may shock you that the core technology of many of these have stayed the same for decades.
What makes a technology retain its usefulness throughout time? A strong design? Popularity? Whatever the explanation, here is a list of several technologies that have not needed much modification for over 4 decades. Virtual Memory – 1962 – This allows systems to use hardware memory more resourcefully by recycling space used for memory. This concept led to time-sharing or the ability for systems to multi-task. MOS Chip – 1967 – Metal-oxide semiconductor. This technology is used today to make computer chips and is known as CMOS (complementary metal-oxide semiconductor). The technology has changed a bit over time so adaptability is one trait that has kept it alive. C programming language – 1969 – Designed by Dennis Ritchie at Bell Labs, C is the most common and widely used programming language in the world. Once you get something right why change it? These technologies have maintained their validity for over 50 years and are the core foundation of a variety of technologies today. As we demand more out of our tech we may see these evolve or disappear. But for now they remain some of the most steadfast, innovative creations in the computer world for the past century.
