DOS stands for Disk Operating System, and is one of the first operating systems for personal computers. This operating system was a cut-down implementation of the CP/M operating system designed for the 8088 family of computers. The original implementation, called QDOS (Quick-and-Dirty Operating System), was designed by Tim Patterson for Seattle Computer Products. This product was eventually licensed to Microsoft, and Microsoft then demonstrated the operating system to IBM.
IBM originally used the acronym DOS in the early 1960’s for their disk operating system for the 360 series computers.
CP/M originally stood for Control Program / Monitor, and was programmed by Gary Kildall for both the 8080 (IBM) and the Z80 (Apple II) family of microcomputers. Many of the characteristics of CP/M have been attributed to early versions of DEC operating systems like TOPS-10, OS/8, RSTS, and RSX-11.

- Runs on Intel 8088/8086 procesors. Alternative to CP/M
- 16-bit system with rudimentary features for accessing 20-bit memory space. The memory managment is a real mess.
- Got popular because IBM licensed it for their PCs and for some strange reason IBM was considered market leader in late 80's
- Directory structure similar to Windows (actually windows is derived from DOS) but no shortcuts and only 8-character name plus 3-character extension is allowed
- Quite small, only uses some 60 KB of memory
- Does not use protected mode, i.e. application can do anything: bypass OS to access disks, reboot the system etc.

Features? What features? No really, it wasn't a bad OS for it's time and there's DOS-based apps that allow you to do the basic things Windows can do but it's time to move on. There's plenty of online resources that give you DOS commands for different versions.

Freespire blows! So does the new UBUNTU. They totally screwed UBUNTU up. It used to be nice. Linspire also sucks Open Suse is nice as well as Mandriva. Both have good features and eye candy.
