In a quad-core processor there are four logical processors on the chip that can do processing at the same time. On an dual core processor there are two logical cores. This is sometimes enhanced through "Hyper Threading". This is where each core can handle two processes at the same time. So a dual core processor with Hyper Threading can perform as if it were a quad-core processor. This takes up less space and generates less heat within the processor for the same workload.
Sorry, there was a problem. Please try again later.It is the number of cores your computer's processor has. It increases the processing speed of your computer, because, any job you ask the computer to do, the operating system tries to split the job across all the cores(and executes them in parallel), and returns the result to you faster. So dual is 2 core processor and quad is 4 core processor. To take advantage of the cores, you need not do anything specific to make your computer faster. The programs that you run usually try to figure it out by themselves. In general, the rule of thumb is, the more the cores, the faster the computer can perform.
