In computing, the reset vector is the default location a central processing unit will go to find the first instruction it will execute after a reset.
The reset vector is a pointer or address, where the CPU should always begin as soon as it is able to execute instructions.
The address is in a section of non-volatile memory (such as BIOS or Boot ROM) initialized to contain instructions to start the operation of the CPU, as the first step in the process of booting the system containing the CPU.
