What Does the CPU Do?Īs we said earlier, the CPU is the brain of your computer. For a full explanation of Moore’s Law, click here. It is not a law of physics or a law of natural science-it is due to the projected growth rate of the number of components per integrated circuit. It is Moore’s idea that the number of transistors in an integrated circuit doubles every two years. Moore’s Law takes its name from Intel co-founder Gordon Moore. You’ll understand this faster performance if you know a thing or two about Moore’s Law. And they are performing faster than ever before. The graphics card’s only function is to take the data and transform it into the images you see on your monitor.Īs technology advances from year to year, we see CPUs getting smaller and smaller. The memory component and the CPU are separate from your graphics card. It acts upon the memory component, which stores all the data and information on your system. It sits upon the motherboard (also called the main circuit board) and is a separate component from the memory component. The CPU is sometimes called the brain of the computer. It is the core of your computer, and your computer cannot function without it. By diverting complicated tasks to the chips best equipped to handle them, it allows your computer to run at its peak level. The CPU takes the basic instructions you command on your computer and allocates those jobs to other chips in your system. It is a critical component that dictates the way your computer will perform and determines how well it can do the job. The CPU (central processing unit) is the core of every smartphone, tablet, and computer. You cannot understand the function of one without understanding the capabilities of the other. What Are Central Processing Units?īefore you can understand threads, you’ll need to have a basic understanding of what a CPU is. We’re diving into further detail on exactly what threads are, why you need to understand what they do, and why they’re so important. Threads are important to the function of your computer because they determine how many tasks your computer can perform at any given time. A processor with eight cores will have 16 threads.Ī processor with 24 cores (yes, those exist), will have 48 threads. So a processor with two cores will have four threads. The number of threads you have depends on the number of cores in your CPU.
All CPUs have active threads, and every process performed on your computer has at least a single thread. Threads refer to the highest level of code executed by a processor, so with many threads, your CPU can handle several tasks at the same time.
