The CAB method, also known as the ‘Control-Alt-Backspace’ method, is a technique used to restart a computer system in order to resolve technical issues or errors. This method involves pressing the ‘Control’, ‘Alt’, and ‘Backspace’ keys simultaneously, which triggers a soft reboot of the system. It is often used as a last resort when other troubleshooting methods have failed, and can help to restore functionality to a frozen or unresponsive computer. The term ‘CAB’ is derived from the three keys involved in the process, and has become a popular term among tech-savvy individuals.
