Ip Address is a unique address assigned to each computer on a network in order to identify and communicate with each other utilizing the Internet Protocol standard (IP)

Basic Format

A IP address consists of 4 parts (known as Octet), each having three digit ranging from 0 -255 separated by a decimal point.

Example of Valid IP:

CHKDSK —  Creates and displays a status report for a hard disk and can correct errors on the disk if required. Used without any parameters, CHKDSK simply displays the status of the disk in the current drive. Used with parameters. CHKDSK can locate bad sectors, repair the disk and recover readable information.

To see a status report of the disk, at a command prompt, type, chkdsk and press ENTER. If errors are found, any error message will appear.

To repair errors with the disk, at the command prompt, type chkdsk /f/r and press ENTER. The parameter /f fixes errors on the disk, /r locates bad sectors and recovers readable information. If  you receive a message that chkdsk cannot run because the volume is in use by another process, this probably means that you are trying to fix errors  on the disk that you are currently using. You cannot do that but the computer can repair errors at startup, and you should schedule an autostart in the bootup.
