In order for a PC to run you will need the following:
Power Supply (most important as it supplies power to your PC)
Motherboard (think of it as the spinal cord of your PC)
CPU (the brains, will not run without it)
RAM (this is the memory in which your OS and applications are run from)
Hard Drive (this is where your Operating System is stored, as well as data)
These are the electronic components needed to run a PC.
However there are other items needed to run it effeciently and safely:
A PC tower (in which to store the electronic components)
PC Fans (in order to keep the system cool which drastically increases it's efficiency and life)
CPU cooler (another fan which keeps the CPU cool and running effectively)
Mouse (in order to navigate the PC)
Keyboard (in order to input information)
Monitor (in order to see the information)
There is a difference between running a PC, and operating a PC.

The case containing the Hardware components of a computer system is called a Desktop or Tower:
A Tower is much larger than a desktop computer, and heavier. it cannot be put on its side, unlike a desktop where it can fit on the desk either lying down or stood up.
A desktop computer is smaller than a tower and is lighter, it can fit on a desk stood up or lying down, depending on the size of the desk.
Many people would consider the central component of a computer to be the CPU, or Central Processing Unit.
The motherboard. It holds the CPU, RAM, ROM and media chips, as well as video and audio for the monitor.

The central processing unit (CPU) is the brain of your computer. CPU is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output operations specified by the instructions. Following are the prime components of CPU: - The arithmetic logic unit (ALU), which performs arithmetic and logical operations. - The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
The Major components of the typical desktop computer are the following: CPU (central processing unit) RAM (Random Access Memory) Hard Drive CD/DVD/BluRay/CD-ROM drive (optional) Video Card
The "primary circuit board" for a computer is called the "Motherboard". This is the board that contains the housing and sockets for all of the coprocessors, resistors, and circuit pathways that make your computer operate. This board also contains expansion slots, in which you insert expansion cards, extending the capabilities of the system.
The six hardware components of a computer system are the central processing unit (CPU), primary storage, secondary storage, input devices, output devices, and the communication devices. The central unit of a computer is the CPU.
