Question: what is the difference between dual core and multicore processors?
Answer: Multi just means "more than one". Dual means "two". So a dual-core CPU has 2 CPU cores, no more, no less. A multi-core CPU has 2+, you can buy CPU's with 2/3/4/6/8 cores these days I believe so it really depends specifically on which multi-core CPU your comparing to which dual-core CPU.
