Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware.
Slow write, fast read storage Read/write storage which allows information to be overwritten multiple times, but with the write operation being much slower than the read operation. Examples include CD-RW and SSD. Write once storage Write once read many (WORM) allows the information to be written only once at some point after manufacture ...

A programmable read-only memory (PROM) is a form of digital memory where the contents can be changed once after manufacture of the device. The data is then permanent and cannot be changed. The data is then permanent and cannot be changed.
The data segment is read/write, since the values of variables can be altered at run time. This is in contrast to the read-only data segment ( rodata segment or .rodata ), which contains static constants rather than variables; it also contrasts to the code segment , also known as the text segment, which is read-only on many architectures.
In computer technology, read-only can refer to: Read-only memory (ROM), a type of storage media; Read-only access to memory using memory protection; Read-only access to files or directories in file system permissions; Read-only access for database administrators in database system permissions
