Code-hidden in the language behind the computer soft and hard the Nineth chapter of binary

1. American mathematician John Wildert is aware that with the popularization of computers, binary numbers are likely to play a more important role in the future. He decided to create a new, shorter word instead of a very inconvenient five-syllable word, and in the end he chose the short, simple, delicate, and very lovely word bit;

2. Decimal is no different than other digital systems, but we usually use it to count. But the binary system has a little particularity. The particularity is that it is the simplest digital system that people can get;

The new word 3.bit is not just the meaning of the binary digits that dolphins use to count. In the computer age, bits are seen as the basic unit of information blocks.

=============================================================================================================== ========================

This time, but the binary understanding, haha. To forgive such an ignorant reading note, bit is a bit. Binary digits and bits are considered to be the basic unit of the constituent information block.

=============================================================================================================== ========================

4. The amount of information transmitted by BITS is minimal. 1 bits is the smallest amount of information that can exist. Any content that is less than 1 bits is not information at all. Since 1 bits represents the smallest possible amount of information, a more complex number of bits can be expressed using a multi-bit binary;

5. In other words, all information that can be converted to a choice of two or more possibilities can be expressed in bits. There are many forms of human communication that cannot be expressed by the choice of the possibility of either or or.

6. An additional benefit of using binary representation of information is that we can clearly see if we have thought of all the possibilities.

=============================================================================================================== ========================

It is appropriate to represent information in binary notation. 1. The amount of information can be very small, 2. It is possible to represent all possibilities with the smallest amount

=============================================================================================================== ========================

7. Whenever we talk about bits, we usually refer to a certain number of bits. The more bits we have, the more different possibilities we can express;

8. In binary, the number of possible encodings is equal to the power of the whole number of 2, and its power exponent is the bit number of bits, and each additional bit will increase the number of encodings by one times;

9. If you know the number of encodings you want to use, how many bits do you need to calculate? In other words, in the table above, how can the number of words in the code to roll back the bit? The method to be used is called the logarithm operation with the base of 2, the inverse of the logarithm operation;

=============================================================================================================== ========================

Binary involves some mathematical operations, familiar with times, its meaning from now Ah, ha!

=============================================================================================================== ========================

Binary, for me this layman is somewhat understood, ha. At the end of this chapter, bits can represent text, pictures, sounds, music, movies, product codes, film speeds ... At its root, bits are numbers.

When we use BITS to represent other information, all we have to do is calculate how many possibilities we have. This determines the number of bits we need so that each possibility can be assigned to a number.
