A single Board Computer is a fully functional computer that is miniaturized to the size of a credit card, more or less. It’s a computer in a single boar.  Now clearly you might raise the question. Are there many Board systems as well? Well, as a matter of fact, yes. There is a difference between traditional c and single board computers. You have to be known that full-fledged systems like PCs and Mac have a motherboard. On the motherboard, you will really find a processor and other circuitry related to that. You will also locate slots for other peripherals like RAM, ROM, Hard Disk, LAN Card, CPU Fan, Heat Sink, LCD monitor, etc. These peripherals require to be attached to the motherboard alone in order to build the PC/Mac fully functional service.

Unlike PCs/Mac, single board systems consist of all on a single board itself. On the board, we have a processor and all other vital peripherals and circuitry as well. We have onboard RAM, ROM, flash storage space, AV ports, etc. This means that one board is enough to act as a full-fledged system. Yes, even they are able to boot into an operating system OS like Linux, Android, etc. also operate like any other system. Being lightweight and exact, they have established huge application in smartphones, tablets and other consumer products.

These single board systems are not as great as the present day PCs, laptops or Mac, and hence do not dispel a lot of heat. In adding to that, the processors are designed in order to make less heat and consume less power. That’s why you can run your Smartphone the whole day without charging the battery or cooling it down!

The entire electronic device that you see around smartphones, tablets, etc. has one such single board system. Nearly all of them will run Android and iOS an OS just like Windows, Linux, etc.
