What is the function of ROM in computer?

Answer 1

• Read-only memory, a type of storage media which is used in computers and other electronic devices. This tells the computer how to load the operating system.
  • older Mac computers typically included Old World ROM
  • newer Mac computers typically included New World ROM
• ROM image, a computer file which contains a copy of the data from a read-only memory chip
• ROM (MUD), a popular MUD codebase
• Random oracle, as in "random oracle model", a mathematical abstraction used in cryptographic proofs
• ROM cartridges, a portable form of read-only memory

Answer 2

Answer: Read-only memory (usually known by its acronym, ROM) is a class of storage media used in computers and other electronic devices. Because data stored in ROM cannot be modified (at least not very quickly or easily), it is mainly used to distribute firmware (software that is very closely tied to specific hardware, and unlikely to require frequent updates). Since ROM (at least in hard-wired mask form) cannot be modified, it is really only suitable for storing data which is not expected to need modification for the life of the device. To that end, ROM has been used in many computers to store look-up tables for the evaluation of mathematical and logical functions (for example, a floating-point unit might tabulate the sine function in order to facilitate faster computation). This was especially effective when CPUs were slow and ROM was cheap compared to RAM. Example: A current mico-wave oven uses ROM to store its menu, given that the menu will not change; at least on that particlar micro-wave oven.

Answer 3

ROM stands for Read Only Memory. it is basically a set of instructions the computers follows to run its programs.unlike RAM, ROM cannot be written into and only read from. only the manufacturer has control over the ROM.

Answer 4

ROM is used to store the basic input/output system.
