Question 1:What is DOS?

DOS (Disk Operating System) is an acronym for several closely related operating systems that dominated the IBM PC compatible market between 1981 and 1995, including MS-DOS and PC-DOS. It provides a command-line interface for user interaction and is primarily used for managing files, running software, and controlling hardware.

Question 2:What are the primary functions of DOS?

The primary functions of DOS include:

File Management: Creating, deleting, copying, and moving files.
Program Execution: Running software applications.
Device Control: Managing peripheral devices like disks, printers, and keyboards.
Memory Management: Allocating and deallocating memory for programs.

Question 3:What is the difference between MS-DOS and PC-DOS?

MS-DOS (Microsoft Disk Operating System) was developed by Microsoft and widely licensed to OEMs for IBM PC compatibles, while PC-DOS (Personal Computer Disk Operating System) was an IBM-branded version of MS-DOS. Functionally, they are very similar, but PC-DOS was tailored specifically for IBM PCs.

Question 4:How do you view the contents of a directory in DOS?

You can view the contents of a directory using the DIR command. For example, typing DIR C:\ displays the files and subdirectories in the root directory of the C: drive.

Question 5:Explain the purpose of the COPY command in DOS.

The COPY command is used to copy files from one location to another. For example, COPY C:\file.txt D:\backup\file.txt copies file.txt from the C: drive to the D: drive.

Question 6:What is the function of the CHKDSK command?

The CHKDSK (Check Disk) command is used to check the integrity of the file system on a disk and fix logical file system errors. For example, CHKDSK C: checks the C: drive for errors.

Question 7:How do you delete a file in DOS?

You can delete a file using the DEL or ERASE command. For example, DEL C:\file.txt deletes file.txt from the C: drive.

Question 8:Explain how you would troubleshoot a DOS boot issue.

Troubleshooting a DOS boot issue involves:

Checking Hardware: Ensure all hardware components are properly connected and functioning.
Boot Sequence: Verify the boot sequence in the BIOS settings.
Boot Disk: Use a bootable DOS disk to start the system and check for configuration issues.
AUTOEXEC.BAT and CONFIG.SYS: Examine these files for incorrect or problematic entries.
System Files: Ensure that key system files (COMMAND.COM, IO.SYS, and MSDOS.SYS) are present and not corrupted.

Question 9:What is the purpose of the FDISK command in DOS?

The FDISK command is used to create, delete, and manage disk partitions. It allows users to set up the hard drive for use by defining primary and extended partitions

Question 10:How do you check the version of DOS you are running?

You can check the DOS version by using the VER command, which displays the version of the operating system. For example, typing VER might return MS-DOS Version 6.22
