How does the RAM.

The chips of random access memory (RAM) to the computer are what a blank canvas is to a painter. Before the
PC can do something useful, it needs to move programs from disk to RAM. The data contained in the documents, spreadsheets,
graphics, databases or any other type of file must be stored in RAM, even temporarily,
before the program can use the processor to manipulate them.

No matter what type of data you are using your personal computer, or the level of complexity of such data. For the PC,
they are just 0s and 1s. Binary numbers are the native language of computers, even the largest and most powerful computer
is essentially a collection of keys that open key is 0, and a closed one. This is usually called the
machine language. From this numerical system greatly simplified, the computer is able to construct representations
of millions of numbers, any word in any language and hundreds of thousands of colors and shapes.

Since humans are not as fluent in binary notation as computers, all these binary numbers appear on the screen
a readable form - usually letters of the alphabet or decimal numbers. For example, when you type A, the operating system
and the program using a convention known as ASCII, in which certain figures represent certain letters. The computer is
basically a handler numbers, hence it is easier for the machine to work with binary numbers. On the other hand,
is easier for programmers and others use decimal numbers. The capital letter A corresponds to the number
decimal 65, B 66, C is 67, and so on. But the heart of the computer, the numbers are in their armazendos
binary equivalents.

These are binary notations that occupy PC memory and disks. But, when you turn on the computer for the first time
RAM is empty. The memory is filled with 0s and 1s read from disk or created by the task that you perform on your computer.
When the PC is turned off, everything was in RAM disappears. Some new types of RAM chips retain discharges
power when the computer is turned off. But most of the memory chips only work if there is a source of
continuously supply electricity to the thousands or millions of individual electrical discharges that make programs
and data stored in RAM.
