The storage form of multimedia information in computers is "binary digital information". Computers can only recognize 0 and 1, so all information is stored in the machine in the form of 0 and 1 (i.e. binary); numerical values are expressed in binary form, and for non-numeric information (characters, graphics, sounds, etc.) ) is processed by binary encoding it.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The storage form of multimedia information in the computer is "binary digital information".
Binary is a number system widely used in computing technology. Binary data is a number represented by two digits, 0 and 1. Its base is 2, the carry rule is "when two are entered, one is added", and the borrowing rule is "borrow one to be equal to two".
The basis of computer operations is binary. Computers can only recognize 0 and 1, so all information is stored in the machine in the form of 0 and 1 (ie binary), and the storage unit used is bytes.
In electronic computers, numbers are represented in binary form. Non-numeric information (characters, graphics, sounds, etc.) is processed by binary encoding.
The main reasons for using binary within computers are:
1. Simple technical implementation: computers are composed of logic circuits, and logic circuits usually only have two states. , the on and off of the switch, these two states can be represented by "1" and "0".
2. Strong anti-interference ability and high reliability: only two numbers 0 and 1 are used in binary, which is not prone to errors during transmission and processing, thus ensuring high reliability of the computer.
3. Simple operation rules: Compared with decimal numbers, the operation rules of binary numbers are much simpler, which not only simplifies the structure of the arithmetic unit, but also helps improve the operation speed.
4. Suitable for logical operations: Logical algebra is the theoretical basis for logical operations. Binary has only two digits, which coincides with "true" and "false" in logical algebra.
5. Easy to convert: Conversion between binary numbers and decimal numbers is quite easy. When people use computers, they can still use the decimal numbers they are accustomed to, and the computer automatically converts them into binary numbers for storage and processing. When outputting the processing results, it automatically converts the binary numbers into decimal numbers, which brings great convenience to work. .
Binary is a number system widely used in computing technology. Binary data is a number represented by two digits, 0 and 1. Its base is 2, the carry rule is "every two is forwarded to one", and the borrowing rule is "borrow one to be equal to two", which was discovered by Leibniz, the German master of mathematical philosophy in the 18th century. The current computer system basically uses a binary system, and data is mainly stored in computers in the form of two's complement codes. The binary system in the computer is a very tiny switch, with "on" representing 1 and "off" representing 0.
