Imagine a great leap in Technology where your Computer has 128KB of RAM, no Internet ability. You insert a Cartridge to load in your Operating System known as Basic. Your Programs which are limited in scope and function are on a Cartridge or a 5 1/4 Floppy Disk. Your printer is a Thermal Printer, you bought a CRT (cathode ray tube) Monitor, no mouse, but you have a keyboard nicknamed the "Chiclet" which is a wireless Infrared, and you can get a Joystick.
You upgraded by using device known as a sidecar adapters and had to hunt down upgrades from store to store to try to breach the 128KB threshold. You didn't have the graphic icons to select a program. You used Command-Line User Interface to interact with your computer. All of the upgrades you did yourself, this fantastic technology came with a reasonable price in today's dollar of about $3480.00 or approximately $2,000.00 dollars when I bought my IBM PCjr, in 1984. Even today the average Computer User does not spent half of $2,000.00 for a home computer or laptop. I believe it was money well spent to introduce me into the Computer World and its advances.
Bill Gates is quoted as saying: "If GM had kept up with technology like the computer industry has, we would all be driving $25 cars that got 1,000 MPG."
During my education at the FBI National Academy over 11 years ago. The lead instructor stated at that time "Every 6 months new computing and/or mobile phone technology will be introduced to the public," that statement has proved to be true.
Since 1984 when I started personal computing, there have been amazing changes in the computing and mobile phone technology. Advances in computing included hardware, software and the operating systems that brings them together.
Like the Operating Systems I used through the years: IBM Operating System of Basic, and Microsoft Operating Systems: DOS, Workgroups 3.1, Windows 95, 98,
2000, ME, XP, Vista, Windows 7, 8.1, Windows 10. Taking courses for Windows Server 2012 and several courses from the Linux Academy and Linux Foundation including Linux Administration.
Increasing knowledge by also taking courses to achieve certification's by Microsoft as a System Builder for several of their Operating Systems and a Microsoft Registered Refurbisher.
The journey through this Computing Evolution and its adventures has taught me a
great deal about this wonderful, consuming and continuously advancing technology. This learning process will always continue in order to serve my customers better.
