The MS-DOS memory environment
Jerry Crow · ACM SIGICE bulletin/SIGICE bulletin · 1996
When I first started experimenting with and using MS-DOS in 1986, I was confused by the various types of memory available with the then contemporary PCs: expanded, extended, enhanced expanded, etc. I found that I was frequently asked to explain the concepts associated with these terms and, frankly, could not do so. I decided to remedy that situation by researching the subject and acquiring sufficient knowledge to permit me to understand what was happening from a hardware and software standpoint vis a vis the MS-DOS memory environment. When I had accomplished that task, I wrote an article for the Phoenix PC Users Group Newsletter documenting my new found knowledge. The original article was published in 1989.
