I am going to write a review for my new iMac and I don't understand how quad core and threads are used in applications. Can someone give me a laymans description on how programs use this technology? Is it like dual cpu's or .....
thx.

It counts for the amount of processes at any given time. Quad Core means you have 4 "Cores" inside of your processor that can work individually or all together. Threads are actions taken by the computer in the very basic of terms. A task or a job.

Think of a CPU as a toll booth, and cores as lanes passing through.
More cores should allow for more traffic throughput.

And how about threads? i7 has 4 cores and 8 threads, while i5 only 4 cores, what's the best analogy for it?

Can I say i7 is like toll gate with 4 booths and each booth contain 2 officers, makes total 8 officers can serve 8 vehicles at a time?

And i5 is like 4 toll booths with 1 officer / booth?
