ok, so im planning getting a new laptop. has t4400 dual core 2.2, a buddy of mine told me that software doesnt recognize2nd core. please explain difference between dualand duo? is he correct what is the difference here?
Dual Core is a processor with two cores, Intels branding for this is called Core2Duo.
Some programs are only able to use one core, however these are becoming rarer, all operating systems support two cores, so they can spread the load across the two cores. If you for example have 2 programs open then they can both run at full speed.
Having a dual core system will make things feel much faster than single core.
