COMPUTER FUNDAMENTALS

Detailed explanation-1: -Read-only memory, or ROM, is a type of computer storage containing non-volatile, permanent data that, normally, can only be read, not written to. ROM contains the programming that allows a computer to start up or regenerate each time it is turned on.

Detailed explanation-2: -read/write memory A type of memory that, in normal operation, allows the user to access (read from) or alter (write to) individual storage locations within the device. The choice of read or write operation is normally determined by a read/write signal applied to the device. RAM devices are typical read/write memories.

Detailed explanation-3: -It is called read only memory as we can only read the programs and data stored on it but cannot write on it. It is restricted to reading words that are permanently stored within the unit. The manufacturer of ROM fills the programs into the ROM at the time of manufacturing the ROM.

Detailed explanation-4: -Answer: The statement is false. Read-only memory (ROM) is also known as firmware. We can only read data but cannot write on it. Read only memory is non-volatile in nature, i.e. data is not lost when power is off. A ROM stores such instructions that are required to start a computer.

Detailed explanation-5: -ROM can be read from but not written to. ROM can be read from but not written to, hence the term read only. This makes ROM ideal for storing instructions and data that are needed for the computer to run. These instructions and data are usually programmed by the computer’s manufacturer and cannot be overwritten.
