Well, the below video will show the revolution of computers through the Computer History Museum.
It first introduce the architecture of the stored-program computer which was invented by John von Neumann. This computer can store a memory of 4k which is only about 4 pages of text. Yes! It may seem like a joke and we're probably wondering what kind of storage is that even accounted for. But, without his invention, we'd probably not be able to enjoy having our computers containing all our documents and photos and softwares and musics, etc.
They then introduce the 1st hard drive, followed by the SAGE and the German Enigma machine and Google's First server.
This is probably one way to illustrate Technological Diffusion because through time, as computers are recreated, people come to a point to adopt them (compare today's computer with the earliest ones). If people have not decided to adopt the new ones, we would
probably still be using the huge and bulky computers without any colours.
Furthermore, the only reason to why generations after generations continue to adopt the new technology is due to all the reasons under Technological Diffusion:
1. Cost-benefit tradeoffs
where it is way cheaper nowadays to get a computer
2. Functionality
it has the latest system to help us reach out to everyone else,
contains the latest functions, etc.
3. Substitutes
replacing the heavy and bulky ones which takes up alot of space
4. Complements
ability to use with the latest gadgets such as our mobile phone,
internet, video conference, etc
So next time, when you decide to complain how heavy your laptop is, compare it with the older ones which could probably take up the entire space of your room and try thinking how you're going to move it from one place to another.
