what is ram

The computer (or computer data) is a machine designed for electronic data processing. It is composed of several distinct units, all of these devices properly connected together form a system of electronic data processing.
HARDWARE identifies all parts of the computer that you can touch, see, that thus have a certain consistency. It stands in central processing unit (CPU) .
The CPU performs all the operations necessary to operate the computer. It can be said that the CPU is the brain of the computer.
The UNIT 'devices are components that are joined by electrical connections to the central
control, such as keyboard, monitor, etc.. And What is ram we will covering letter. know If the hardware is the physical component of the computer, the software it is intangible, not perceptible to the touch, but which performs important tasks in the computer system. It receives commands for the computer processing of data provided by the user. The software makes it possible to use a computer. The system software includes programs that are responsible for operating the system and its individual components. Their task is to establish a coordination and linkages between the various components of the system. The software takes care of this connection is called BIOS (Basic Input Output System).
What is ram ? In a computer there are 2 types of memory: RAM and ROM memory. The RAM (Random Access Memory) is also known as direct memory access. Everything is in it is erased when you turn off your computer. RAM is volatile. The data is irretrievably lost and therefore it is convenient to save the data on mass storage, on hard disk. The various components of the RAM are called cells, each cell has its own name so that the computer can detect the cell with the desired information. This name is said to address and is composed of binary numbers.
Memory ROM (Read Only Memory) is also known as read-only memory. This memory, in fact, one can only read and you can not change its contents. In this memory are the programs you need to boot the machine, known as system programs, and the BIOS. The ROM is not volatile, that is not erased when the computer power is removed.
The hard disk (or hard drive) is a device used for storing long-term data on a computer. It is not unlike the RAM.(what is ram)
