RAM - random access memory

RAM (pronounced ramm) is an acronym for random access memory, a type of computer that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.

Types of RAM

There are two different types of RAM:

 DRAM (Dynamic Random Access Memory)

 SRAM (Static Random Access Memory).

The two types of RAM differ in the technology they use to hold data, with DRAM being the more common type. In terms of speed, SRAM is faster. DRAM needs to be refreshed thousands of times per second while SRAM does not need to be refreshed, which is what makes it faster than DRAM.

DRAM supports access times of about 60 nanoseconds, SRAM can give access times as low as 10 nanoseconds. Despite SRAM being faster, it's not as commonly used as DRAM because it's so much more expensive. Both types of RAM are volatile, meaning that they lose their contents when the power is turned off.

RAM, Main Memory and ROM Explained

In common usage, the term RAM is synonymous with main memory, the memory available to programs. For example, a computer with 8MB RAM has approximately 8 million bytes of memory that programs can use. In contrast, ROM (read-only memory) refers to special memory used to store programs that boot the computer and perform diagnostics. Most computers shave a small amount of ROM (a few thousand bytes). In fact, both types of memory (ROM and RAM) allow random access. To be precise, therefore, RAM should be referred to as read/write RAM and ROM as read-only RAM.

RAM - memoria de acceso aleatorio

RAM (se pronuncia ramm) es un acrónimo de memoria de acceso aleatorio, un tipo de ordenador que se puede acceder al azar, es decir, cualquier byte de memoria se puede acceder sin tocar los bytes precedentes. RAM es el tipo más común de memoria encontrado en ordenadores y otros dispositivos, como impresoras.

Tipos de RAM

Hay dos tipos diferentes de RAM:

 DRAM (Dynamic Random Access Memory)

 SRAM (memoria estática de acceso aleatorio).

Los dos tipos de memoria RAM se diferencian en la tecnología que usan para almacenar los datos, con DRAM es el tipo más común. En términos de velocidad, SRAM es más rápido. DRAM necesita ser refrescado miles de veces por segundo, mientras que SRAM no tiene por qué ser renovado,
