DISK OPERATING SYSTEM

What is a disk operating system?

Stands for "Disk Operating System." DOS was the first operating system used by IBM-compatible computers. It is a powerful, low-level operating system that controls and supervises how programs run on your computer. DOS provides instructions to the computer to interpret hardware input to your keyboard and mouse. It provides print control and works with other connected hardware. DOS uses a command line, or text-based interface, that allows the user to type commands.

DOS is a single-user, single-task computer operating system with a command line interface. It's one of the best operating systems in spite of its simplicity and small size. The most popular and widely used version of the DOS family operating systems is MS-DOS, or Microsoft Disk Operating System.
It is still included with Windows, but is run from the Windows operating system instead of the other way around. The DOS command prompt can be opened in Windows by selecting "Run..." from the Start Menu and typing cmd.

    An operating system (OS) is an interface between hardware and user which is responsible for the management and coordination of activities and the sharing of the resources of the computer that acts as a host for computing applications run on the machine. As a host, one of the purposes of an operating system is to handle the details of the operation of the hardware. This relieves application programs from having to manage these details and makes it easier to write applications. Almost all computers (including handheld computers,desktop computers, supercomputers, video game consoles) as well as some robots, domestic appliances (dishwashers, washing machines), and portable…

    Intro to Operating System

    To understand three operating systems, you must first know what an operating system is. An operating system is software that controls the computer. It manages hardware, run applications, provides’ an interface for uses, stores, retrieves files. Here are three operating systems DOS, Windows 2000, and Linux. DOS, which is a disk operating system was the first OS within IBM computers. DOS was the operating system utilized by early versions of Windows including Windows 3.1 and 3.11. Next you have Windows 2000, which is an upgraded version of Windows NT and comes in numerous versions some are designed for the desktop and other designed high-end servers. Windows 2000 was a popular choice for corporate offices and their employees. The ultimate reason Windows 2000 was so successful over Windows NT was because it was more stable, support for Plug and Play, device manager, recovery console, activity directory, and better network support. At this time Windows 2000 is a dying operating system and provides no support from Microsoft due to the newer operating systems coming out at this time. The third operating system would be Linux is predominantly used for servers. Between Windows, and Mac, Linux is not a high option and is actually one to two percent of the desktop market.

    Purpose of an Operating System

    Some professionals in the Information Technology (IT) field might describe the Operating System (OS) of a Personal Computer (PC) as its software brain. Jean Andrews, Ph.D., describes an OS this way: “An operating system is software that controls a computer. It manages hardware, runs applications, provides an interface for users, and stores, retrieves, and manipulates files” (Andrews, 2010). In other words, the OS is the Graphical User Interface (GUI) from which the PC’s operator controls any piece of hardware or software. Before installing an OS, a user must understand the purpose that it serves – why it is important to have an OS. Once understanding what purpose the OS serves to the user, he/ she will understand how this can help to operate and maintain his/ her own computer. Eventually, the user should hope to gain enough knowledge about a particular OS, that he/ she will be able to assist others with installing it on another PC.…
