![]() ![]() There will be two main categories of Surface tablets - one for casual consumers and another for professionals who want a tablet for productivity applications. Whether or not they qualify as a full PC depends more upon your personal definition of what makes a personal computer. Does that mean all tablets are PCs? They're definitely all computer devices. The circuits identify the location of your finger and register it as a touch, mapping it to a command. Circuits at the edges of the screen detect the decrease in electrical charge across the screen. When you touch the screen, your finger interrupts a weak electric field. It uses a capacitive screen, meaning that the computer detects when there is a change in the electrical potential across the screen. The Surface's touch-screen interface sets it apart from an average computer. It's sort of like the nervous system for the device. It also creates the path for the graphics processor to send information to the display. This is what lets the CPU pull information from memory or hard drive space. It allows the various electronic components within the Surface to connect to each other through dedicated pathways. The motherboard is a special type of circuit board. This is where the Surface stores applications and files.Īnother similarity between the Surface and a PC is the motherboard. The Surface has solid state memory, which is like a PC's hard drive. This removes the need for the CPU to pull data from a hard drive, which can be a slower process. With more memory, the computer can hold more data in temporary storage. A computer's speed depends partly on the power of the processor and partly on how much memory the computer has at its disposal. Memory is where a computer stores data until it's needed for an operation.
