External command are such short programmes or utilities which are available on pc and hard disk. These get loaded in the memory of the pc when specially ask four some of the external command. That you will offen use are Forman, print, chkdisk, etc.
DOS Commands
DOS (Disk Operating System) is an old operating system that was widely used on IBM-compatible personal computers during the 1980s and 1990s. It is a command-line based operating system that uses text commands to perform various tasks. Here are some commonly used DOS commands with examples:
1. DIR - This command is used to list the contents of a directory.
Example: To list the contents of the current directory, type "dir" and press enter.
2. CD - This command is used to change the current directory.
Example: To change to the directory "C:\Windows", type "cd C:\Windows" and press enter.
3. COPY - This command is used to copy files from one location to another.
Example: To copy a file named "file.txt" from the current directory to the directory "C:\backup", type "copy file.txt C:\backup" and press enter.
4. DEL - This command is used to delete files.
Example: To delete a file named "file.txt" from the current directory, type "del file.txt" and press enter.
5. MD - This command is used to create a new directory.
Example: To create a directory named "test" in the current directory, type "md test" and press enter.
6. RD - This command is used to remove a directory.
Example: To remove a directory named "test" from the current directory, type "rd test" and press enter.
7. TYPE - This command is used to display the contents of a text file.
Example: To display the contents of a file named "file.txt" in the current directory, type "type file.txt" and press enter.
Functions of DOS:
DOS (Disk Operating System) was a simple operating system that provided a basic set of functions that allowed users to manage files, run programs, and perform other tasks. Here are some of the main functions of DOS:
1. File Management: DOS provided a set of commands that allowed users to create, copy, move, and delete files and directories. Users could also view the contents of files and directories, and change the attributes of files and directories.
2. Program Execution: DOS provided a command shell where users could run programs and batch files. Programs could be run by typing the name of the program followed by any necessary parameters. Batch files could be created to automate repetitive tasks by executing a series of commands.
3. System Configuration: DOS provided tools to configure the system, such as setting the date and time, configuring hardware devices, and changing the system configuration files.
4. System Maintenance: DOS provided tools to maintain the system, such as checking the disk for errors, formatting disks, and backing up important files.
5. Network Functions: Some versions of DOS provided networking functions, which allowed users to connect to other computers on a network and share files and resources.
While DOS was a simple operating system, it provided a solid foundation for personal computing in its time, and its functions have influenced modern operating systems in many ways.
