Why Is knowing about PC history Important?
Why it is most important to understand the history, development, and evolution of the PC. The simple truth is that doing so makes you a much better technician, troubleshooter, and problem solver! PCs are complicated devices with a lot of building methods and troubleshooting, and much of this is caused by one important design or architecture parameter, backward compatibility. It is amazing, but one can actually run many 1981 programs on a modern operating system, and in many cases even connect old hardware as well. Modern PCs may look very different and be far more powerful and compatible than the first PCs built-in 1981, but internally they have a lot of the same DNA.
Understanding how the design or architecture of the PC has evolved into what we use today will help you when solving or troubleshooting problems as you will have a deeper understanding of why things are done the way they are and what problems can be caused by them. For example, many modern systems come with solid-state drives (SSDs), those drives are built to basically look and act like magnetic hard disk drives, even present as if they have interior structures like “tracks” and “sectors.”
If you had not before learned or known about magnetic drives, you would not understand why SSDs are designed the way they are and what problems might occur because of it. Such as why in some cases they might display to slow down dramatically after a period of use. Knowing the history and development of PC architecture will make you much more in-tune with how and why modern systems are designed and especially how they function and possibly fail.
