In the CPU, the full spelling of CS is "Code Segment", which translates to "code segment register", which corresponds to the memory area where the code is stored in the memory, and is used to store the entry address (segment base address) of the memory code segment area.

When the CPU executes an instruction, the memory address of the next instruction to be executed is determined through the code segment register (CS, Code Segment) and instruction pointer register (IP, Instruction Pointer).
Similar registers in the CPU are:
DS: Acronym for Data Segment, translated as "Data Segment Register";
SS: is the abbreviation of Stack Segment, translated as "stack segment register";
ES: It is the abbreviation of Extra Segment, translated as "additional segment register".
