Thanks to the discovery of signal and how they work, we now have useful everyday technology that make our lives easier. Some examples would be telephones, radios, computers, etc that require signal to connect to other sources that are further away. In the old days, there were lots of wires because these wires carried signals from state to state. First off, signals are what you want to receive and transmit that aid in better communication. The more signal there is then the greater the quality of sound that you get, but the further the other receiver is away, the weaker the signal. Then there are transistors that made portable radios possible without the heat, tubes, and more power. Eniac had about 19,000 tubes for their computer systems that they ran on and had instructional punch cards. These set of punch cards had different programming instructions that told the computer what to do, but it was tedious to use because they had to be in an exact order or the computer wouldn’t function the way you wanted it to. Transitioning it was hard too because they could get out of order or miss a card which would take forever to fix because it is not instantly fixable like modern computers.
I found this lecture’s overall concept to be fascinating and I loved learning about early computers and how they got to where they are now. Although once the technical stuff kicked in, it started to get harder to follow and became less interesting. None the less, still an intriguing topic that people had these ideas about computers and were able to make it come to life and have it actually work. Seeing the evolution of technology get this far because of the progress throughout the decades are far beyond what is thought to be possible. It is mind blowing what people could come up with and turn it into a reality.
