How does one interpret the information printed out by the following command in Linux

cat /proc/cpuinfo

On my laptop, I get the following output.

Now it says that there are 4 processors on the system. There is also a field inside the information of each processor field which says cou cores are 2.

Does that mean there are 4 Intel i3's CPU's on my system? What does the processor field really mean here?

This question came from our site for professional and enthusiast programmers.

How is this a programing related question? Voting to migrate to superuser. – talonmies Feb 9 '12 at 20:43
@talonmies: Well, I'd expect more less average programmer to be able to understand/figure out what CPU machine is using, how much memory it has etc, you know. Though this question is more suitable for superuser anyway. – user49531 Feb 9 '12 at 20:53

Unfortunately for you, no :) You have only one i3 CPU with two cores and enabled hyper-threading. For a detailed information on how to read cpuinfo, see
