Disk operating system

It has a 1.44 Mb floppy drive, CD reader and is operating from a single removable 2-5 Gbytes Disctec hard disk. Operating system is IBM OS2 Warp 3.0 with some Windows applications. The power requirement for the PC is 110-240 V AC, 50-60 Hz/5 A.

PCs use a disk operating system that controls the file system and how the applications communicate with the hard disk. Networks use a network operating system (NOS) to control the communication with resources and the flow of data across the network. The NOS runs on the server. Many companies offer software to start a network. Some of the more popular network operating systems at this time include Unix, Novell s NetWare, and Microsoft s Windows NT Server (or Windows 2000). Although several other NOSs exist, these three are the most popular. 

In the 1980s or early 1990s, the operating system that shipped with most PCs was a version of the Disk Operating System (DOS) created by Microsoft MS-DOS. (There were a number of manufacturers of DOS, but most of them produced similar versions—they differed only in syntax and a few utilities. The important differences among DOS variants are to be found from one chronological version to the next, not among manufacturers.)...

I he Microsoft Disk Operating System, or MS-DOS, was never meant to be extremely friendly. It had its roots in CP/M, which, in turn, had its roots in UNIX. Both of these older operating systems were command line-based, and so was MS-DOS. In other words, they all used long strings of commands typed in... 

MSDOS. SYS Functions primarily to handle disk I/O, hence the name disk operating system (DOS). Just like 10. SYS, MSDOS. SYS is loaded into memory at bootup and remains in memory at all times. 

DOS 1. Acronym for Disk Operating System, an operating system originally developed by Microsoft for the IBM PC. DOS exists in two very similar versions MS-DOS, developed and marketed by Microsoft for use with IBM-compatible computers, and PC-DOS, supported and sold by IBM for use only on computers manufactured by IBM. 

MS-DOS Acronym for Microsoft Disk Operating System. MS-DOS, like other operating systems, allocates system resources (such as hard and floppy disks, the monitor, and the printer) to the applications programs that need them. MS-DOS is a single-user, single-tasking operating system, with either a command-line interface or a shell interface. 

PC-DOS 1.0 Microsoft s Disk Operating System is generally referred to as MS-DOS. When it was packaged with IBM s personal computers, though, DOS was modified slightly and was called PC-DOS. 

Quick-and-Dirty Disk Operating System (QDOS) Created by Tim Patterson of Seattle Computer Products, QDOS was the basis of MS-DOS. QDOS was purchased by Microsoft and renamed MS-DOS.

Fourier transform infrared (FTIR) spectra were measured using a Dlgilab FTS-14 spectrometer with the Real Time Disk Operating System (RDOS). The samples were scanned 256 times at a resolution of one point every four wavenumbers with double precision. 

Like many others, I worked on mainframe computers in the 1970s, cursing their inflexibility on a frequent basis. The first personal computer I used (in 1979) was a Commodore PET, which used audio cassettes for data storage. The IBM PC was introduced in 1981 but required the user to be fluent in the Disk Operating System (DOS) computer language. DOS was an early Microsoft development, but it was very clumsy. I remember the first time I used an Apple Macintosh in 1984. You switched it on and it just worked. I remember thinking, This is what computers should be like )...
