How does the transistor.

The transistor is the base of building all microchips. He can only create binary information: 1, if the current
are passing, and 0 if not. From these 1s and 0s, called bits, a computer can create any
number, if any transistors grouped sufficient to manage the 1s and 0s needed.
The binary notation is quite simple:

Decimal, binary number

Personal computers such as those based on Intel microprocessors 8088 and 80286, are 16-bit PCs. This means that
can work directly with binary numbers of up to 16 homes or bits, which, translated into decimal numbers, equivalent
to 65,536. If the operation requires a number greater than one, the PC must first break these numbers in
smaller components, perform the operation on each component, and then recombine the results into a single response. PCs
more powerful microprocessors based on Intel 80386 and 80486 are both 32 bits, ie, can handle
binary numbers with up to 32 bits - equivalent to 4,294,967,296 decimal notation. The ability to work with up to 32 bits
in turn makes these PCs much faster.

The transistors are not only used to record and manipulate numbers. The bits can also mean true (1)
true or not (0), which enables computers to work with Boolean logic. The combinations of transistors
in various configurations are called logic gates, when they are arranged in arrays (arrays) are called
half-adders (half adders), which in turn are combined into full-adders (full adders). More transistors 260
are needed to create a full adder (full adder) that can manage mathematical operations to numbers
16 bits.

In addition, the transistors makes it possible that a small amount of electric current flowing over another control
strong - even as a small amount of electricity needed to run a wall switch can control
most potent energy that comes through the wires to the bulb.
