I need help from all the experts, I am a beginner, I am looking at assembly language and I am stumped at the beginning.

What is the relationship between binary numbers and decimal and hexadecimal numbers in machine language? How to convert? What are the advantages of hexadecimal? Why are they all represented in hexadecimal? Aren't data transmission and storage all binary numbers?

What is the relationship between binary numbers in machine language and decimal and hexadecimal?

The same number can be expressed in decimal, binary, or hexadecimal. Binary 0101 and decimal 05 represent the same number.

[What are the advantages of hexadecimal? Why are they all represented in hexadecimal?]

Nowadays, eight binary bits are used as one byte (early computers used six or seven bits). Two hexadecimal characters can represent one byte, which is more convenient.

Beginner compilation! ?

Why give yourself such a difficult start?

College students should start learning MCU in assembly language, at least we learned assembly language at that time.

This depends on what stage you are in. College students should still follow the pace of the school, but you can get a relatively complete study material such as Zhengdian Atom.

If you use binary system to calculate, you will be exhausted. So you should use hexadecimal system to deal with people.

For example, 32-bit binary and hexadecimal

11111111 11111111 11111111 11111111

0xffffffff

Which one do you prefer? Machines recognize the ones above, but humans prefer the ones below, right?

There are decimal, signed numbers, floating point, double precision, all of which are for people. People who do mathematics like to do these.

The CPU, memory, etc. are all binary internally, but it is inconvenient to use binary when programming. Generally, hexadecimal or decimal is used, and the compiler or assembler will automatically convert it into binary.

Different formats, but still the same thing

There are a lot of garbled characters in the post, and I don’t know what to say…

If you want to get timely and effective help, first describe the problem correctly and completely.

Machines only recognize binary information. Humans use decimal numbers. Octal and hexadecimal numbers are very convenient to convert into binary, and they require fewer bits than binary, making them easier to write. However, they must ultimately be converted into machine language through an assembler for use by machines.
