ROM Definition

1. Dedicated resource that usually varies between 4 and 8 MB of physical space, with the aim of allowing the computer system to load the basic commands and functionalities necessary for the initialization of the operating system and the applications that one has installed, that is, for For example, for Windows to start when you turn on the computer, someone has to notify you.
Thus, the initials refer to Read-Only Memory (read-only memory), which implies that the content of the ROM cannot be modified, nor can anything be added, however, within the ROM there is a interface called BIOS (initials for Basic Input/Output System) through which the user can select between certain configuration options; In general, to enter the BIOS on a PC, one must repeatedly press F10 seconds after pressing the power button. The invention of this technological concept dates back to 1932, with the Drum memories engineered by the Austrian Gustav Tauschek, whose first model had a space capacity of 62.5 kilobytes.

Etymology: Developed in the computational field in the 1960s, on principles and advances worked since 1930. It is reflected in the Latin memoryrooted in the adjective memoryin the sense of ‘conscious’, ‘memory’. + ROM, initials of English that represent Read-Only Memory.

Grammatical category: noun fem.
in syllables: memory + rom.

ROM memory

A ROM memory is that storage memory that allows only the reading of the information and not its destruction, regardless of the presence or not of an energy source that feeds it.

It is a semiconductor memory that facilitates the preservation of information that can be read but cannot be destroyed. Unlike a RAM memory, the data contained in a ROM is not destroyed or lost if the flow of information is interrupted and for this reason it is called “non-volatile memory”.

ROM or read-only memories were often used as the primary data storage medium in computers. Because it is a memory that protects the data contained in it, avoiding their overwriting, ROMs were used to store system configuration information, boot or startup programs, hardware, and other programs that do not require constant updating.

While the operating system used to be stored entirely in ROM during the early decades of computers, these systems now tend to be stored in newer flash memories. Previously, there were no efficient alternatives to ROM memory, and if more memory or a software or system upgrade was needed, it was often necessary to replace the old memory with a new ROM chip. Today computers can keep some of their programs in ROM, but flash memory is much more widespread, including in mobile phones and PDA devices.

In addition to computers, video game consoles continue to use programs based on ROM memory, such as the Nintendo 64, Super Nintendo or Game Boy.

Due to the speed of use, the information contained in a ROM memory is usually passed to the RAM when it is required for the operation of the system.
