That can either mean a dual-socket machine with dual-core CPUs (two CPUs with two cores each) or a quad-core CPU (one CPU with four cores).
Core 2 duo is dual core. And before that was core duo which was dual core too...
´Dual core' just means that there are 2 separate cores in the CPU. Intel has made dual core pentuim 4, core duo and core 2 duo CPUs. ´Core 2 Duo´ is just one type of dual core CPU that Intel has made.
A generic "dual core" processor is any processor which has two separate processors on a single chip. This should not be confused with the Pentium Dual-Core, which was a brand of dual core processors which used the Pentium architecture on each core. The Core 2 Duo is also a specific processor from Intel. The Core 2 is a brand of microprocessors based on the Core architecture. The Core 2 Duo specifically refers to a dual core version of the Core 2 brand.
quad core has 4 cores a dual core has 2 cores
There is no difference between dual core and core 2 duo. Intel just name its recent family of dual core processors as "core 2 duo". Both (core 2 duo and dual core) works in same fashion.
A "dual core" CPU is one that has 2 CPU cores (as opposed to 1 in older computers). "Core 2 Duo" is line of (dual core) CPUs produced by Intel.
Dual core. Since it is dual core, it can do 2 processes at once, making it similar to a 4GHz single core
Dual core is two cores on one chip. core 2 duo is two separate chips. Dual core is slower because they have to share the same input output stream.
Dual core 2 is the 2nd version of the dual core processor and quad core is obviously 4 cores in a processor.
core 2 duo will be better.
