Rom memory meaning (what is it, concept and definition)

What is ROM Memory:

The ROM is the storage medium of programs or data that enable the proper functioning of computers or electronic devices through reading information and may not be destroyed or reprogrammable. The meaning of ROM is " Read Only Memory " translated to the Spanish " Read Only Memory."

ROM memory is known as non-volatile memory since the information contained in it is not erasable when turning off the electronic device.

ROM memory is installed on the motherboard, where the basic information of the computer, called “BIOS,” is located.

The oldest ROM memory is the MROM stores indestructible data and for the update of the software or data it is necessary to replace the chip which cannot be done by anyone but by an expert or the same manufacturer, with technological advances few programs are stored in ROM memory since most of them are in new ROM memories; Erasable Programmable Read Only Memory (EPROM) is reprogrammable and erasable memory through strong ultraviolet rays, and Electrically Erasable Programmable Read-Only Memory (FLASH EEPROM) can be reprogrammable, erasable and allows to alter the content through signals electrical.

Since 2007 it is very difficult to find devices with ROM memory since reprogrammable equipment is more flexible and economical.

What is ROM memory for?

The ROM memory is of utmost importance for the proper functioning of computers and electronic devices, since when the ROM memory is turned on it allows the initial program to start, which will initiate the entire system.

ROM memory is used to store firmware programs, that is, to store operating system programs, language interpreters, control programs (turn on the equipment); programming information tables (numerical use tables); and other programs that do not need to be constantly modified or updated.

ROM and RAM memory

The information contained in the ROM memory is not erasable when the computer is turned off or with the power cut, which is why it is called non-volatile memory, while the information contained in the RAM or volatile memory is erasable and can get lost in case the user does not save the information on the computer, for example: when we write in Word, the information must be saved.

RAM is faster to read than ROM, which is why the information contained in ROM is normally transferred to RAM.

The RAM memory is of random access since the information remains recorded in the electronic device and its quick access is possible.
