This is in direct contrast to other memory types, where it is possibe to read and write data and store it in memory. It is mainly used to store programs and data which generally do not need any modification throughout the life of the device. +Read-only Memory (ROM) is a self descriptive type of memory that references the idea that a computer and its applications can only read data from it.

It is mainly used to store programs and data which generally do not need any modification throughout the life of the device. + ### Examples of ROM #### BIOS ROM -In the early days of modern computers, one of the most common ROM chips used was the BIOS (Basic Input Output System) ROM. The chip would hold specific instructions that a computer needed in order to start up and it was critical that the information could not be accidentally modified. Once the BIOS ROM chip was installed (generally soldered to the motherboard), it could not be modified. Fast forward to the 2000's and BIOS technology had improved to where a BIOS could now use EPROM (An erasable type of ROM) where the instructions could be updated in a controlled fashion by the manufacturer, but the operation of the chip would still have the same behavior in being read-only. The act of "updating the BIOS" for a computer is infact updating the programmaing of the EPROM Bios. +In the early days of modern computers, one of the most common ROM chips used was the BIOS (Basic Input Output System) ROM.

The devices used to read the data house the lasers and are called CD-ROM Drives. The disc itself is generally created in a factory and once made, is read only. This is in contrast to the CD-R (compact disc recordables) medium which has the additional ability to hold new data.
