#Memoria rom mac#
Resulta que se han encontrado imágenes en blanco y negro de algunos desarrolladores del equipo Macintosh encriptadas entre el código fuente de la memoria ROM del Mac SE. For example, the Internet browser you are using to read this page is loaded into RAM and is running from it.Los chicos de NYC-Resistor han hecho un descubrimiento la mar de interesante para los veteranos que hayan vivido los primeros años de vida de Apple. RAM is one of the fastest types of memory, allowing it to switch quickly between tasks. RAM chips are used in computers and other devices to store temporary information produced by programs quickly. The oldest ROM-type storage medium can be dated back to 1932 with drum memory. ROM chips were also used in gaming system cartridges, like the original Nintendo, Gameboy, Sega Genesis, and others. Using a non-volatile storage medium is the only way to begin this process for computers and other devices. Computer ROMĪ good example of ROM is the computer BIOS, which is a PROM chip that stores the programming needed to begin the initial computer startup process.
Storage capacity of ROM and RAMĪ ROM chip stores several MB (megabytes) of data, usually 4 to 8 MB per chip, whereas a RAM chip can store multiple GB (gigabytes) of data, ranging from 1 to 256 GB per chip. A RAM chip temporarily stores files in use on a computer, like a document you're writing, an image you're editing, or data for a game you're playing. For example, a ROM chip is often used to store the BIOS program on the motherboard. Uses of ROM and RAMĪ ROM chip is used primarily in the startup process of a computer, whereas a RAM chip is used in the normal operations after the operating system is loaded. Essentially, ROM is used for permanent storage, and RAM is for temporary storage. By contrast, a RAM chip is volatile, which means it loses any information it is holding when the power is turned off. Laptop RAM is about half the length of desktop RAM.įurther explanation of differences Storage capabilities of ROM and RAMĪ ROM chip is a non-volatile storage medium, which means it does not require a constant source of power to retain the information stored on it. Desktop RAM is about 5 ½ inches in length and 1 inch in width. RAM is available in two primary sizes, whether used in a desktop computer or a laptop. ROM can vary in size from less than an inch in length to multiple inches in length and width, depending on their use. RAM chips often range in storage capacity from 1 to 256 GB. ROM chips often have a storage capacity of 4 to 8 MB.
RAM is used in computers to temporarily store files in use on the computer. ROM was used as the storage media in a Nintendo, Gameboy, and Sega Genesis game cartridge. ROM is often used to store the BIOS program on a computer motherboard. RAM is volatile, requiring power to store data. ROM is non-volatile, not requiring power to store data.
