DOS Shell - Shortcomings

Shortcomings

DOS Shell was incapable of full multitasking. It supported rudimentary task switching; it could switch between programs running in memory, at the cost of performance hit. However, all the running programs had to fit into conventional memory area, as there was no support for paging to disk. (Programs with DOS extenders such as DOS/4GW were immune to this issue as DOS/4GW spared conventional memory from overflow.)

In time, Windows 3.1x, with its own graphical user interface, became much more popular among computer users. Windows was capable of multitasking. System performance was much higher, with complete access to the system's memory.

Famous quotes containing the word shortcomings:

    The higher, the more exalted the society, the greater is its culture and refinement, and the less does gossip prevail. People in such circles find too much of interest in the world of art and literature and science to discuss, without gloating over the shortcomings of their neighbors.
    Mrs. H. O. Ward (1824–1899)

    I feel a kind of reverence for the first books of young authors. There is so much aspiration in them, so much audacious hope and trembling fear, so much of the heart’s history, that all errors and shortcomings are for a while lost sight of in the amiable self assertion of youth.
    Henry Wadsworth Longfellow (1807–1882)

    One of the most highly valued functions of used parents these days is to be the villains of their children’s lives, the people the child blames for any shortcomings or disappointments. But if your identity comes from your parents’ failings, then you remain forever a member of the child generation, stuck and unable to move on to an adulthood in which you identify yourself in terms of what you do, not what has been done to you.
    Frank Pittman (20th century)
