there's some questions about deep computer stuff....so i need help from comp. wizzes?

Question

1)what are the versions of windows that are 16-Bit Graphed Shells?
2) What is the difference between MSDOS and PCDOS?
3) What is cooperative multitasking?

Answer 1

Cooperative multitasking is contrasted with preemptive multitasking in an operating system.
CM: does NOT interrupt the current task except at specific program points where the program returns control to the operating system for a system service. The application program controls when task switching may occur. This reduces the task switching overhead but makes the system less responsive to real-time events. Example: Windows 95
PM: The operating system gains control of the processor when interrupts occur (keyboard input, hard drive read/write completion, real-time clock, etc.) and may perform a task switch at an arbitrary point in the currently active program. More information must be saved and restored, but there is less delay in responding to the interrupt. Video and audio streams are unlikely to have gaps of silence in them with this method. Example OS/2

I have not kept track of Windows or DOS features on PC's though I have used MSDOS 5 and 6, Windows 3.0, 3.1, 95, 98SE, 2000 and XP. I recommend that you look up the historical information with Google.

Answer 2

I can only awnser question 2 so here goes.

MsDos is obsolete on newer systems, it's only on very old PC's.
PCDos is a screen that you pull up while runing windows, it's a comand promt in the system. MsDos isn't run seperate of windows. just familierize yourself with PCDos and you shoud be just fine, PC and MS are pretty much the same thing anyway.

Answer 3

How 'bout you do your own homework. This "deep computer stuff" you refer to really isn't that deep. A little effort on your part to look around the internet will give you the answers you need. Who knows you might actually learn something -- some basic grammar, to start with.

And by the way, the person who posted after me doesn't know what he/she is talking about.

Answer 4

That is obsolete
