to run these command presence of there own files in the disk is not nessecry. When we swich on the computer these commonds are automatically loaded is in run these are called internal command

CD\ Will take you right back to just the C:\> Prompt. You can use CD.. to step up one level at a time, but CD\ is quicker.

1. single user.

2. single tasking

3. not supports networking

4. supports only character line interface(CLI).

5. simplicity and transparency.

MS DOS is an acronym for Microsoft Disk Operating System. MS Office is an acronym for Microsoft Office which is a word processing, spreadsheet, and presentation application.

You will need at least 2.5 MB of disk space for ms-dos 6.22.

MS-DOS supports multiprogramming to some extent.-

Because word processing software is notorious for inserting all kinds of control characters and other formatting data into files. The processes that run autoexec.bat cannot understand that data and the autoexec.bat may fail to run properly.

There are web browsers, e-mail clients, messaging soft, other networking sofware for DOS. The nature of DOS imposes certain restrictions, so Windows, Mac OS X or Linux like experience should not be expected. But basic use is surely possible. [For some details see related links below]

I'm assuming you are asking about Windows Vista Features. There is an extensive and thorough discussion on this issue at the "bleeping computer" website, which begins with the following statements: "A Windows Vista feature is simply a set of programs or a particular capability of the operating system that can be enabled or disabled by an administrator. It is important to note that in Windows Vista, when you remove or disable a feature, you are not actually removing files from your hard drive, but rather just deactivating them. Therefore disabling a feature should not be used as a method of freeing up hard drive space. On the other hand, by disabling a feature you may gain an increase in performance due to memory and processor utilization no longer being allocated towards the particular feature."

CorelDraw is a vector graphics editing and creation tool.

MS Office is a suite of software for office productivity: Word (word processing) Excel (spreadsheet calculations) PowerPoint (presentation) etc...

There's Windows 95 and everything that came before it (including at least Windows 3.x and probably Windows 2.x). Windows 98 still seems like it's running on DOS, but it's a little different.

The answer that you are looking for is on page 271 of the Operating Systems Book;

MS-DOS is command driven.

No. Windows XP has it's own kernel and memory management system.

• In DOS, 8 characters.
• In Windows, 254 characters.

DIR is used to list the contents of a directory.

windows PE is a vast improvement over ms-dos because it includes internal support for TCP/IP networking stack and is capable of functioning as a windows file sharing client.

Generally, MS-DOS boots starting with the first available floppy drive. Then it checks the hard drive and then any additional hard drives if they are properly registered in the CMOS. Then it eventually checks any optical drives. But this all depends on the exact BIOS and the CMOS settings. With some BIOSes, you can disable the floppy boot or make it try the floppies after the hard drive.

MS-DOS has few practical advantages these days. However, it is relatively small in size, and is universally compatible with all PCs (since it was designed to run on the very first one). It starts up fairly quickly on most hardware, uses little memory, and allows direct access to hardware, unlike most protected mode operating systems today.

DOS still exists because some of the very old but still useful products only run with DOS so it would be silly to destroy it. The way that I understand it DOS still exists because of how memory still is allowcated with the "infamous" 640K barrier. Despite the amount of memory computers have, up to Windows XP memory was still based on the same structure that was in the first PC which had a mb of ram. A lot of log jams in memory occur while the programs are trying to page through this small section of memory. Another reason is to allow 16 bit programs, in particular, to run under Windows OSes though XP.

I do not know if this structure persists in Windows-64 (64 bit Windows) or Windows Vista. It was my understanding that the next version of OS was going to eliminate both the backward compatibility and 640K barrier.
