Everything You Need to Know About Computer Hardware

Computer hardware refers to the physical components that make up a computer system.

There are many different kinds of hardware that can be installed inside, and connected to the outside, of a computer.
Computer hardware may sometimes be seen abbreviated as computer hw.

List of Computer Hardware
Here are some common individual computer hardware components that you'll often find inside a modern computer. These parts are almost always found inside the computer's housing:

• 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.)

Here is some common hardware that you might find connected to the outside of a computer, although many tablets, laptops, and netbooks integrate some of these items into their housings:

• Monitor
• Keyboard
• Mouse
• Battery Backup (UPS)
• Flash Drive
• Printer
• Speakers
• External Hard Drive
• Pen Tablet

Here are some less common individual computer hardware devices, either because these pieces are now usually integrated into other devices or because they've been replaced with newer technology:

• Sound Card
• Network Interface Card (NIC)
• Expansion Card (Firewire, USB, etc.)
• Hard Drive Controller Card
• Analog Modem

Some of the devices listed above are called peripheral devices. A peripheral device is a piece of hardware (whether internal or external) that isn't actually involved in the computer's main function. Examples include a monitor, video card, disc drive, and mouse.

Troubleshooting Faulty Computer Hardware

Computer hardware components individually heat up and cool down as they're used and then not used, meaning that eventually, every single one will fail.
