why computers use binary data

Electronic computers can process information and processing at very high speeds, including data processing and processing, and have a great capacity for storing data. Data in the computer in the physical state of the device, using a binary digital system, the computer proces

Only 0 and 12 states, the need to represent 0, 12 states of electronic devices many binary number of the algorithm is less, the operation is simple, the computer operator hardware structure greatly simplified (decimal multiplication 99 Table 55 formula, Binary multiplication has only 4 rules) since the binary 0 and 1 are exactly the same as the false (false) and

is also very simple, such as the first State (1) + The second state (2) = The third State (3). You see:00000001 +00000010---------= 00000011, according to the form of the search, is 3, it is so simple.So, don't think about 10 and 2 in the brain how to convert, these dirty work tired, can computer to do. You just have to remember that the "binary states" in the table are just a few of the 10 binary.Also, the disk of the 2, with the magnet of the N-pol

When using OpenCV to develop programs, it is difficult to view matrix data, while matlab is very convenient to view data. One method is hybrid programming of matlab and c ++, you can use matlab to access the c ++ memory. Unfortunately, I will not use this method, so I will write the

Chinese gossip to him, and he unsanitary environment to study it. Only Yin (-) and Yang (a) two symbols, but can form 8 different kinds of GUA, further can be transformed into 64-gua. This made him suddenly brainwave, "can you use ' 0 ' and ' 1 ', respectively, instead of the gossip in the yin and yang, with Arabic numerals to show it?" Under the guidance of this idea, he repeated the study, and finally found that the

Here, binary computing can be divided into two types: addition and subtraction and multiplication and division. This article discusses addition and subtraction. (1) prerequisites-data storage and representation on computers Start with a question: the value range of byte (1 byte, 8 bits) in Java is-2 ^ 7 Question: We generally think that if one of the eight digi

Sometimes you need to use python to process binary data, such as accessing files and using socket operations, you can use the python struct module to process binary data in c. sometimes, you need to

Use vstruct to parse binary data Vstruct is a module written purely in Python and can be used for parsing and serializing binary data. In fact, Vstruct is a submodule of the vivisect project, which is initiated by Invisig0th Kenshoto and is specially used for

JavaScript is good at handling strings, but because it was originally designed to work with HTML documents, it is not very good at processing binary data. JavaScript has no byte type, no structured type (structured types), and even no byte array, only numbers and strings. (Original: JavaScript doesn ' t have a byte type-it just has numbers-or structured types, or http://skylitecellars.com/even by Te Arrays:

By convention, I will first introduce what is BSon. BSon is short for BinaryJSON and is a binary storage format of a type of Json. Currently, Bson is mainly used by MongoDB (an open-source database with a popular non-Relational Data Model) to store data and exchange network data. Next we will go to the topic to introdu

Binary data may be images, sounds, or any other data. If we can express these binary values as constants, we can directly use the transcat-SQL statement to insert and update the data in the da
