I am reading some Operating Systems materials. I read this phrase that confused me a little: "Multicore refers to a computer or processor that has more than one logical CPU core, and that can execute multiple instructions at the same time."
What is a "logical CPU core", is it a processor? Does it correspond to something physical, or is it the OS which sees logical CPU cores but in reality there is less physical processors than logical CPU cores?
I guess it referes to ALU (Arithmetic Logical Unit) of CPU.
The ALU unit of any proccessor is the part pf the CPU reasponsible for performing all the arithmetic and logical operations.
