A user communicates with the operating system by using a keyboard. You can also communicate with the operating system by using a mouse.
An operating system that doesn't have a graphical user interface, you have to run it using commands only.
it depends on your operating system. On windows the command is: ipconfig /all
That would depend on what operating system you are using. Every operating system has its own tools for checking hard drive and file system consistency.

You haven't indicated what operating system you are using. For windows, using the 'ipconfig /all' command will show you what the DHCP server address is.
Windows Vista is the operating system.
It depends on the operating system you are using. Most windows systems use the 'ipconfig' command to look at the network adaptor configuration, whereas Unix/Linux use the 'ifconfig' command.
The purpose of a keyboard in relation to a computer is to provide input. It is for using program applications and operating system commands.
Every operating system is unique to the person who is using it!
It reads commands from the user or from a file of commands and executes them, usually by turning them into one or more system calls. It is usually not part of the kernel since the command interpreter is subject to changes. An user should be able to develop a new command interpreter using the system-call interface provided by the operating system. The command interpreter allows an user to create and manage processes and also determine ways by which they communicate (such as through pipes and files). As all of this functionality could be accessed by an user-level program using the system calls, so it should be possible for the user to develop a new command-line interpreter.
