One computer component is a motherboard. A motherboard is the spine of your PC, it is the link between all the different components inside your computer. It is important because without it, none of the computer pieces, such as the CPU, GPU, or hard drive, could interact. Total motherboard functionality is necessary for a computer to work well.
Another computer component is the CPU. A central processing unit (CPU) is an important part of every computer. The CPU sends signals to control the other parts of the computer, almost like how a brain controls a body. The CPU is an electronic machine that works on a list of computer things to do, called instructions. The CPU is important because on the motherboard, the CPU has the capability to interact with and control other pieces of hardware to bring the computer to life.
