Teoría del relé

El relé es un elemento de control cuyo funcionamiento se basa en el electroimán. Este, funciona como un interruptor o como un conmutador automatico.

Sus principales funciones son: abrir y cerrar circuitos sin la intervención de un humano
principales aplicaciones: control de motores electricos, activacion de circuitos de elevada potencia, etc.

MEMORIES

RAM: Random-access memory (RAM /ræm/) is a form of computer data storage which stores data and machine code currently being used. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory.

ROM: Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM can only be modified slowly, with difficulty, or not at all

CACHE: A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory.
