005 - The DOS Commands We Need To Know

The correct answer is MD. This command is used to create a new directory or folder in a file system.

The correct answer is CD because CD is a DOS command that is used to change the current directory. By typing "CD" followed by the desired directory path, the user can navigate to a different directory within the file system.

The command "RD:" is the correct answer because it is used to remove an existing directory. The other commands listed (FDISK, FORMAT, MD, and MEM) do not have the functionality to remove directories.

The correct answer is EDIT. The command EDIT opens a text-editor utility that allows users to create new files or modify existing files. This utility provides a user-friendly interface for editing text and is commonly used for writing and editing code, scripts, or other text-based files. It is a versatile command that helps users manage and manipulate their files effectively.

The correct answer is REN. This command is used to rename a file or directory. It is important to conform to the 8.3 naming convention of MS-DOS when using this command, which means the filename should have a prefix of 8 characters or less and a suffix of 3 characters or less.

The ECHO: command is used to display messages or commands in a batch file. It can be used to provide information or instructions to the user. By using the ECHO: command, the display of commands in a batch file can be turned on or off. This command is useful for displaying messages or instructions during the execution of a batch file.

The VER command is used to report the running version of MS-DOS. It displays the version number of the operating system that is currently running on the computer. However, it is important to note that the running version may not necessarily be the same as the installed version of MS-DOS. This means that even though the VER command may report a certain version, it does not guarantee that the same version is installed on the system.

EMM386.EXE is the correct answer because it is a DOS command that enables expanded memory and allows the use of upper memory as system memory. This command is typically used in the CONFIG.SYS file to load the EMM386.EXE driver, which then provides access to expanded memory and allows programs to utilize the upper memory for better system performance.

The correct answer is DELTREE. The DELTREE command is used in DOS to delete a directory or folder and all its subdirectories or subfolders. This command is useful when you want to completely remove a directory and all its contents from the system. It recursively deletes all the files and subdirectories within the specified directory, ensuring that everything within the directory is removed.

COMMAND.COM is the correct answer because it is the DOS command interpreter that displays the DOS command prompt and contains the internal DOS commands. It is also required for DOS and Windows 3.x to boot. CONFIG.SYS is a system configuration file, while EMM386.EXE is a memory manager for DOS.

The correct answer is DEL:. The DEL: command is used in DOS to delete one or more files or folders from permanent storage, such as a disk. This command allows the user to remove unwanted files or folders and free up space on the storage device.

The TYPE command is used to display the contents of a file on the display.

The correct answer is AUTOEXEC.BAT. This is a system file that was originally found on the MS-DOS operating system. It is a plain-text batch file that is located in the root directory of the boot device.

The SET command is used to assign a value to a variable in a batch file. In this context, it can be used to insert a string value into a command variable that can be accessed by another program or batch file. This allows for the sharing of data between different programs or scripts, making the SET command a useful tool for inter-program communication.

COMMAND.COM is the correct answer because it is the filename of the default operating system shell for DOS operating systems and the default command line interpreter on 16/32-bit versions of Windows (9x/Me). It is responsible for executing commands and running programs in the DOS environment.

MSDOS.SYS is the correct answer because it is the system file that contains the core operating system code, the kernel, in MS-DOS. It is an important file that is run after IO.SYS and is essential for the functioning of the operating system on MS-DOS and Windows 9x systems.

SETVER is a command in MS-DOS that displays the version of the running MS-DOS and allows the user to set the running version to the one required by real-mode programs. This command is useful when running programs that are designed to run on specific versions of MS-DOS, as it ensures compatibility by setting the appropriate version.

CONFIG.SYS is the correct answer because it is a system file used with MS-DOS and OS/2 that is loaded each time the computer first boots up. This file is responsible for controlling components connected to the computer such as memory and other hardware devices. It contains configuration settings and device drivers that are necessary for the proper functioning of the system.

IO.SYS is the correct answer because it is the binary file that is part of the boot sequence for a DOS system. It is an executable program that processes instructions to set up the computer when the operating system is booted.

CONFIG.SYS is not required for DOS or Windows to start. CONFIG.SYS is a text file that contains configuration commands for the operating system. It is used to set various system parameters and load device drivers during the boot process. However, it is not essential for the operating system to start functioning. DOS or Windows can still start without CONFIG.SYS, although certain system settings and device drivers may not be loaded. COMMAND.COM is the command interpreter for DOS, and EMM386.EXE is a memory manager for DOS. Both of these files are necessary for DOS or Windows to start.

The correct answer is MD because MD is the command used in DOS to create a new directory or folder. The given explanation states that FDISK is used to create and manage partitions on a hard drive, which is unrelated to creating directories.

The correct answer is MD. The MD command is used to create a new directory or folder in a file system. It does not display the amount of memory installed or available. The other options, FDISK, FORMAT, and MEM, are also not relevant to the given statement.
