Guess the zodiac sign

1. Content

Binary encoding is the fundamental principle of digital circuits and computer technology. The four images in this exhibition are arranged in binary encoding according to the twelve zodiac signs. Binary numbers can only be represented by 0 or 1, and the four binary values can represent 16 numbers. It is entirely possible to use a symbol composed of 0 and 1 to represent a zodiac sign, and its judgment function is achieved through a switch circuit. When you select according to the chart, it performs a certain conversion in binary encoding to 'guess' your zodiac sign.

When participating, press the reset button to restore the system to its initial state. Observe and determine if there is a zodiac sign of your own in the four images. If the first image has your own zodiac sign, press the button on the first image. If not, do not press the button, and so on. Press the other three buttons. After all the judgments are completed, press the confirm button. When the indicator light is on, it will automatically display your zodiac sign.

2. Principle

Binary is a widely used numerical system in computing technology. Binary data is a number represented by two digits, 0 and 1. Its cardinality is 2, the carry rule is "every two to one", and the borrow rule is "borrow one as two".

Binary numbers are a binary system where every 2 is carried, and 0 and 1 are basic operators; The foundation of computer operations adopts binary. The foundation of a computer is binary. The commonly used base system in early design was decimal (because we have ten fingers, decimal is a reasonable choice, and fingers can represent ten numbers. The concept of 0 did not appear until a long time later, so it is 1-10 instead of 0-9). After the emergence of electronic computers, using electronic tubes to represent ten states became too complex, so all electronic computers only have two basic states, on and off. That is to say, the two states of the electron tube determine that electronic computers based on the electron tube use binary to represent numbers and data. The commonly used base systems are also octal and hexadecimal. In computer science, hexadecimal is often used, while decimal is rarely used. This is because hexadecimal and binary have a natural connection: 4 binary bits can represent numbers from 0 to 15, which is exactly the data that 1 hexadecimal bit can represent. That is to say, converting binary to hexadecimal only requires converting every 4 bits.

Binary '00101000' can be directly converted to hexadecimal '28'. Byte is the basic storage unit in computers. Depending on the word length of the computer, words have different numbers of bits. The word length of modern computers is generally 32 bits, which means that the number of bits for a word is 32. Byte is an 8-bit data unit, and one byte can represent decimal data from 0 to 255. For modern computers with a 32-bit word length, one word is equal to 4 bytes, while for early 16 bit computers, one word was equal to 2 bytes.

3. Purpose

Exhibition items allow viewers to learn about binary knowledge through interactive games, while also learning about binary applications in real-life situations.
