The devices is require to assemble a P.C

The basic parts in a computer are all dependant on each other to carry out their functions. For example, all the parts depend on the power supply for electrical current at the required voltage levels, and some parts, like the central processing unit and memory, are dependant on the motherboard (main circuit board) ot further refine that power for them. This makes it difficult to explain the funcitons of these parts without referring to others, os we will tackle them in an order that minimizes cunfusion.
All in all, there are somewhere between 10 and 15 distinct parts involved in a PC build, including the monitor, keyboard, and mouse. By distinct parts, we mean components you pick off a store shelf or order over the phone or internet. Assembling all these parts to creat a working PC will require you to make a bout 10 push-together connections and secrew in 20 or 30 screws, four here, six there, nothing complicated.
