Computer Hardware: What Is It?

Computer Hardware

Today’s generation is fond of using computers for school or office works, but are you aware that the computer is comprised of hardware and software? You can read here that these two parts make up what we know as computers.

What is Hardware?

Hardware is a collection or a collective term describing the parts which can be physically touched.

These are physical components that are tangible when using the computer.

Computer hardware has two components: the internal and external components. Listed below are some examples of computer hardware that you might have encountered before:

  • Internal Components – These are devices that are built-in to the motherboard of the computer.
  • Central Processing Unit (CPU) – It’s most commonly known as the processor and is a machine that executes computer programs.
  • Motherboard – The mainframe of the computer.
  • Hard Disk Drive (HDD) – This is a permanent computer data storage or memory hardware that stores your OS, files, and applications.
  • Random Access Memory (RAM) – This is a temporary computer data storage that stores temporary data requests.
  • Optical Drive – A drive that allows DVDs, CDs, and Blu-ray optical drives to be connected to your computer, allowing you to peek into its contents.
  • SSD – An SSD is also a type of nonvolatile storage device that stores data on flash memory.
  • Graphics Processing Unit (GPU) – This performs complex geometric and mathematical calculations which are then used for graphics rendering.
  • Heat Sink
  • Power Supply
  • Transistors
  • Chips
  • Universal Serial Bus Ports (USB) – This is a standard cable connection interface which can also be found on your computer and is most commonly used for short-distance digital communications.
  • Network Interface Card (NIC) – A circuit board found in your computer which allows you to connect with a network. Also known as LAN or network adapter, it allows both wired and wireless communications.
  • External Components – Most commonly known as peripheral, they refer to components that are added to the computer system either by plugging them or connecting them.
  • Input Components – These are devices that are used to give data and instructions to your computer. They send information to your computer which is then used for processing.
  • Mouse
  • Microphone
  • Keyboard
  • Touchpad
  • Camera
  • Scanner
  • Stylus or Joystick
  • USB Flash Drive or Memory Card
  • Output Components – These are devices that are used to display information or results on the computer. They reproduce and only receive the data from another device.
  • Monitors
  • Printers
  • Speakers
  • Headphones, earphones, or earbuds


Laptops that were designed for a more portable use also has its own set of hardware components. They mainly have the keyboard, display, and processor all in one case. Tablets are almost the same in that they also have hardware components despite their small structure.

You might have posted pictures of these on Instagram for aesthetic purposes, but hardware devices are more than just decoration for your feeds. These devices are the backbone of the computer you use for schools and works.

It will be best if you manage them with care as they are the first parts to break or receive damage.
