Hardware

Computer hardware is the collection of physical parts of a computer system. This includes the computer case, monitor, keyboard, and mouse. It also includes all the parts inside the computer case, such as the hard disk drive, motherboard, video card, and many others. Computer hardware is what you can physically touch.

"A computer system isn't complete unless there's also software, which is different than hardware. Software is data that's stored electronically, like an operating system or a video editing tool, which runs on the hardware."

List of Computer Hardware

Here are some common individual computer hardware components that you'll often find inside a modern computer. 

  • Motherboard
  • Central Processing Unit (CPU)
  • Random Access Memory (RAM)
  • Power Supply
  • Video Card
  • Hard Drive (HDD)
  • Solid-State Drive (SSD)
  • Optical Drive (e.g. BD/DVD/CD drive)
  • Card Reader (SD/SDHC, CF, etc.)
This is the metal enclosure that contains many of the other hardware components. It comes in various shapes and sizes, but a typical tower model is between 15-25 inches high. Want to know what's inside? Okay, go get a screwdriver and let's open it up. Seriously, if you are really into computers, the best way to learn is to actually get hands-on. To save us some time, however, have a look at this desktop computer case. A computer enthusiast replaced the metal side panel with a transparent one, so we can have a look inside.
 
Although that photo looks pretty cool, it is a bit hard to recognize the individual components, especially with all the connecting wires running through it. This figure shows a more schematic version of a desktop computer, which makes it easier to point out the essential hardware components.
