# This is a binary world of computers and how to calculate it?

Many have cursed their computer for things too literally! It is easy to blame the computer if something goes wrong.

Available at the box office on the market, and the item you bought, the “special” comes at a high price. The manager called for the repair, and what he says?
“We have problems with the computer, it is the wrong price on some things.”

She sat down in a list of addressess your word processor and print party invitations for next week. Then you will find today’s date was included in the signature – the computer!

Perhaps you’ve heard the term “garbage in garbage out”? Someone, at some point had to do on the computer, what he did, decide not to, you deliberately screw up. Computers can do only what they are told they are more logical, as Spock and they take everything literally.

We are going, why they seem so pedantic!

The world around us has many aspects that work the same way as a computer. There are many examples of oppositions, for example, from top to bottom, left and right, front and rear. A light can turn on or off, perhaps it is day or night. Yes or No? You can think of many others. This known system of two possible states of a binary system, if not one, it must be the other.

A computer uses the binary system, the functionality, the base unit, causing a vacuum tube and transistor, then a chip is a thousand times to keep the whole unit. The light is on or off, we talked about above is controlled by a switch. In calculating this switch is a transistor that is on or off.

Now we come to get to the math! Do not worry, it’s simple math! In fact, it is so easy, we have only until the first is true, we can have two states, we count from 0 to 1 (That’s another thing that computers are pedants, they are on, starting with zero).

The binary system is a system of numbers. You are familiar with the decimal system, the 10 numbers 0 to 9 (think like a computer first 0) a. You can find all kinds of numbers for any purpose you want. You probably know ten (12) and also heard a half dozen. If you used your computer a lot you can come to the hexadecimal system. This 0-9 16 ‘figures’, A, F-. Another numbering system used by persons computer system with 8-digit octal, 0-7 a.

Ok so how can we expect with only 0 and 1. Simple, exactly the same way you count in decimal. The first ten numbers are OK, 0-9, but then what? We start again, but add a 1 in 10 or to “one, zero.” This leads to a “nine” and it is “two zero” and so on to “nine, nine”, then add it again to make a 1-100 – “. One, zero, zero ”

If you follow me so far, you’re ready to have the binary sequence, it is much easier. From scratch, we have 0.1 – and that’s it. We follow the same rule, and add a 1, so that “one, zero.” Followed “a, an,” and “one, zero, zero” – “one, zero, one,” etc. These are equivalent to the decimal 0,1,2,3,4,5. What does this have to do with computers? The next.

In our computer, we changed the transistor, as described above. For example, mathematics, we have seen, we have 3 switches. These each represent a binary digit or bit. For the representation of a 1 decimal would this switch OFF, OFF, ON or 001 For 5 in decimal, we would have ON, OFF, ON, 101 or, by extension, you can see that we could go with four switches in 1111 , or 15 decimal.

Another point to note is that each binary digit, or something that has value. Just as in decimal, we have units, tens, hundreds, etc. are the values ​​in binary 1,2,4,8,16,32,64,128 etc. etc. The binary code 1111 is mentioned so 1 +2 +4 +8 = 15 If you wanted to know what binary is 100101100 in decimal, you could add the numbers. In fact, people who work on the basic machine to know “code machine”! For 1111, it would be 17 F in hexadecimal or octal.

This probably seems a long way to work in numbers, until you realize that this “switch” can be found at the speed of one nanosecond, or a billion times per second recall work, important calculations.

This is probably enough to digest in one sitting. The next time we are like a computer adds and multiplies.
