A computer is a complicated machine. It takes practice to be good at building one. A computer is assembled from many pieces. There are few that are vital for the computer to work properly, a motherboard, a processor, a graphic card and a power supply . The motherboard is probably the most important of them all, it works as a brain connecting all of the other elements. It contains the usb ports, hdmi and vga ports and space which is dedicated for the RAM memory. The processor is like a maths teacher. It makes all of the calculations essential for the pc to respond to the users needs. The graphic card is a very important device. It takes calculations made by the processor and turns them into images that are easy to understand by a human being. A fast graphic card is vital for people who enjoy good looking games. There is one last device that is critical for the computer to work, a power supply. The power supply works as a connector between the computer and the power outlet. It powers the computer with electricity which is absolutely fundamental for a PC to work. There are few others parts that come into play, like cables, a fan and a case, but they aren't as important as the ones I described.
