What is RAM memory?
RAM memory (random access memory) is the hardware in a computer device where the operating system (OS), application programs and actual data are stored so that the device's processor can access them quickly. The main memory in a computer is Ram. It is much faster to read and write than other types of storage, such as a hard disk unit (HDD), a solid state unit (SSD) or an optical unit.
La memoria de acceso aleatorio es volatil. This means that data is stored in RAM while the computer is on, but lost when the computer is turned off. When the computer restarts, the operating system and other files are loaded into RAM, usually from an HDD or SSD.

Because of its volatility, RAM cannot store permanent data. La RAM se puede comparar con la memoria corto plazo de una persona y una unidad de disco duro con la memoria largo plazo de una persona. Short-term memory focuses on immediate work, but it can only keep a limited number of facts at a given moment. When the short-term memory of a person is filled, it can be updated with facts stored in the long-term memory of the brain.
A computer also works this way. If the RAM is full, the computer processor must go repeatedly to the hard disk to superimpose the old data in the RAM with new data. This process slows down the operation of the computer.
The hard disk of a computer can be full of data and cannot receive more, but the RAM memory will not be left without memory. Sin embargo, la combinación de RAM y memoria de storage puede agotarse por completo.
How does RAM work?
The term aleatory access applied to RAM comes from the fact that it can be accessed directly from any storage location, also known as any memory address. Originally, the term aleatory access memory was used to distinguish normal central memory from offline memory.
La memoria sin connexion generally referred to magnetic tape from which only a specific part of the data could be accessed by locating the address sequentially, starting at the beginning of the tape. RAM is organized and controlled in a way that allows data to be stored and retrieved directly to and from specific locations.
Other types of storage, such as hard disk and CD-ROM, can also be accessed directly or randomly, but the term acceso aleatorio is not used to describe these other types of storage.
The RAM memory is similar in concept to a set of cells in which each cell can contain a 0 or a 1. Each cell has a unique address that contains the columns and rows. A set of RAM frames is called a matrix and each frame is known as a cell.
To find a specific cell, the RAM controller sends the direction of the column and line through a thin electrical line recorded on the chip. Each row and column in a RAM matrix has its own address line. Any data that is read flows backward in a separate line of data.
RAM memory is physically small and stored in microchips. It is also small in terms of the amount of data it can contain. A typical laptop can come with 8 gigabytes of RAM, while a hard drive can contain 10 terabytes.
A hard disk, on the other hand, stores data on the magnetized surface of what appears to be a vinyl disk. Alternatively, an SSD stores data in memory chips that, unlike RAM, are not volatile. No dependen de tener energÃa constante y no perderán datas una vez que se pague la energÃa. Los microchips RAM se juntan en modules de memoria. Se utiliza un bus, o un conjunto de rutas eléctricas, para connectar las ranuras de la placa base al procesador.
