Operating Systems

Date:2019-07-24

 

 

As mentioned on the home page, I have been dealing with the computers since the early '90s. Started with Commodore and switched to a PC computer shortly after (286SX quickly expanded to 286DX). My first operating system was, of course, DOS where I started to like scripting in the batch file (*.bat) and optimizing system by modifying system files (himem.sys, emm386, etc.). Over the years, I got to know more varieties of systems and stayed up to date with the next releases and their types. The passion for scripts grew and in this way I became a systems expert. I have enriched my knowledge in recent years with a series of professional courses [list of certificates], which place me in the forefront of professionals.
