Computer Windows And DOS 1(TTA)

FAT stands for File Allocation Table. This is a file system structure used by operating systems to keep track of the location of files on a storage device. The FAT contains entries that specify the location of each file on the storage device, allowing the operating system to access and retrieve the files efficiently. The other options, File Accommodation Table, File Activity Table, and File Advantage Table, are not correct definitions for FAT.

The maximum length of a DOS command, including parameters, is 127 characters. This means that the entire command, including any additional information or arguments, cannot exceed 127 characters in length.

The vol command in DOS is used to see the disk volume label. This means that when the vol command is executed, it displays the name or label assigned to a particular disk volume. This can be helpful in identifying and managing different disk volumes within a DOS system.

The correct answer is "undelete". This command is used in DOS to recover a deleted file. When a file is deleted in DOS, it is not immediately removed from the disk, but rather marked as deleted and its space is available for reuse. The "undelete" command allows the user to restore the file by removing the deleted flag and making it accessible again.

Both copy and xcopy are commands in DOS that can be used to copy files or a group of files. They both serve the same purpose and provide similar functionality when it comes to file copying.

The CHKDSK command is used to perform various tasks related to analyzing and diagnosing hard disk errors. It can scan the disk for errors, fix any issues found, and report the status of files on the disk. Therefore, the correct answer is "all of these" as the CHKDSK command encompasses all these functionalities.

The correct answer is "copy c:\ldce.doc a:". This command is used to copy a file named "ldce.doc" from drive C: to drive A:.

The correct answer is "all of these" because chkdsk is a command in Windows that can be used to check and repair the file system on a disk. It can identify and fix bad sectors on the disk, as well as provide information about the occupied space and free space on the disk. Therefore, chkdsk can be used to find out about the disk's bad portion, occupied space, and free space.

The del command in DOS is used to delete files. It allows users to remove specific files from a directory or disk. This command is commonly used to free up storage space or remove unwanted files.

The correct answer is "cls". In DOS, the "cls" command is used to clear the screen and display the operating system prompt on the first line of the screen. This command helps to remove any previous commands or output from the screen, providing a clean and clear interface for the user to work with.

The correct answer is "copy". The copy command is used in DOS to copy files from one location to another. It allows users to duplicate files, create backups, and transfer files between directories or drives. The "disc copy" command is not a valid command in DOS, and the "type" command is used to display the contents of a text file. Therefore, the correct answer is "copy".

The xcopy command in DOS is a versatile tool that can be used to copy individual files or a group of files, as well as directories and their subdirectories. Additionally, it can copy files to a different destination, such as a different directory or even a different disk with a different capacity. Therefore, the correct answer is "all of these" as the xcopy command can perform all of these tasks.

The restore command in DOS is used to retrieve or recover files from disks that were previously backed up using the backup command of DOS. This means that if you have created a backup of your files using the backup command, you can use the restore command to restore those files back to their original location on your disk.

The dir command is used to display the list of files in a directory. It provides a way to view all the files present in a specific directory.

The batch file "auto-exec.bat" is run while booting in MS DOS. This file is automatically executed during the boot process and contains commands that are executed each time the computer starts up. It is commonly used to set up environment variables, load device drivers, and execute other necessary commands to initialize the system.

The format command in DOS is used to perform two tasks: preparing a blank disk and creating a new blank disk from a used one. This means that the command can be used to erase all data on a disk and prepare it for use, as well as to create a new blank disk by formatting a used one. Therefore, the correct answer is "both of these".

MS DOS was developed in 1984. This operating system was created by Microsoft and was the first widely used operating system for IBM-compatible personal computers. It provided a command-line interface and allowed users to navigate and manage files and directories on their computer. MS DOS played a significant role in the early development of personal computing and laid the foundation for future operating systems.

The correct answer is time, type, dir. These are internal commands in DOS, which means they are built-in commands that are directly executable by the operating system. The time command is used to display or set the system time, the type command is used to display the contents of a text file, and the dir command is used to display a list of files and directories in a specified location.

To quit a file without saving in DOS, the combination of keys to be pressed is ctrl+c. This key combination sends an interrupt signal to the running program, causing it to terminate immediately.

The correct answer is "sys" because the "sys" command in DOS is used to copy hidden system files to a disk.

The correct answer is "tree". The "tree" command in DOS is used to display the directory structure in a tree-like format. It shows all the subdirectories and files within each directory, making it easier to understand the hierarchy of the file system. This command is helpful for navigating and organizing files and directories in a DOS environment.

In DOS, the F3 key can be used to repeat the previous command. This key is commonly used to save time and avoid retyping long or complex commands. By pressing F3, the user can quickly recall and execute the last command entered, making it a convenient shortcut in the DOS environment.

The correct answer is "both of the above" because both the "ren" and "rename" commands in DOS can be used to change the name of a file. These commands allow the user to specify the current name of the file and the desired new name, and the file will be renamed accordingly.

The correct answer is "copy contents of one floppy to another." The diskcopy command in DOS is specifically designed to duplicate the contents of one floppy disk onto another. This command allows users to create backup copies of important data or transfer files from one floppy disk to another without manually copying each file individually. It is a convenient and efficient way to replicate the contents of a floppy disk.

The correct answer is "edit, sys, chkdsk". These three commands are external DOS commands that can be used in the command prompt. The "edit" command is used to create or modify text files, the "sys" command is used to transfer system files to a disk, and the "chkdsk" command is used to check the integrity of a disk and fix any errors. The other options listed do not include all three of these commands.
