ROM can be broadly of three types, namely PROM (programmable read only memory), EPROM (erasable PROM), and EEPROM (electrically EPROM). Many versions of EEPROMs are available.
Movies, music
Read-only memory (ROM)
we can say its a kind of ROM... since flash memory is a specialised EEPROM...
DVD-ROM
PROM
The first one is the CD-ROM, the second one is the DVD-ROM, then the DVD-RAM, then the WORM-SAVE, then the Blueray and at least the eresable storages.
Kind of a tricky question. Analysis: you typed ROM Software. What is it you are trying to do. DVD ROM software will do you no good for a CD and vice versa. Additional Info: A DVD will hold at least 4.7GB. A CD will hold only 700MB. Since you stated ROM, I can only deduce that you are not trying to store information, but rather READ from the device.
Read Only Memory (ROM) and Random Access Memory (RAM)
Read-only memory. A kind of file, sometimes used for game emulators.
cdrom is static rom
Assuming your phone has been rooted and a custom recovery app is installed, you can flash any kind of custom ROM. Some users will install different custom ROM's until they find one that they like. Others will install "nightlies" which are beta versions of a ROM that's not fully stable yet, but are updated daily.
Read Only Memory(ROM) Basic Input Output System(BIOS) or firmware chips are "Electrically Erasable and Programmable Read Only Memory(EEPROM)" chips, these kind of chips can be upgraded by flashing.
