There is a type of memory for storing data in the absence of an electrical current, namely ROM (Read Only Memory), which is called read-only memory, sometimes a non-volatile memory because It does not clear when the system is turned off.
This type of memory makes it possible to preserve the data required to start the computer. Indeed, this information can not be stored on the hard disk since the parameters of the disk (essential to its initialization) are part of this data vital to the boot.
Overview
Read only memory devices are a special case of memory where, in normal system operation, the memory is read but not changed. Read only memories are non-volatile, that is, stored information is retained when the power is removed. The main read only memory devices are listed below:
