Come si fa a interpretare le informazioni stampate da il seguente comando in Linux
cat /proc/cpuinfo
Sul mio portatile, ho il seguente output:

Ora si dice che ci sono 4 processori presenti sul sistema. C’è anche un campo all’interno delle informazioni di ciascun campo del processore che dice che i core cou sono 2.
Significa che ci sono 4 CPU Intel i3 sul mio sistema? Cosa significa veramente il campo del processore qui?
