Types of computer

In the past, it was much easier to identify the type of computer you were using. Today, there are desktops, laptops, netbooks, tablets, hybrid computers, and smartphones that are all considered a computer. Below is a visual example of the more common computers to give you a better comparison of the different types of computers.


Once you have identified the type of computer, it can make it easier to help identify the software and hardware running on the computer.

Model number and serial number

Model and serial number

Determining your computer model number and serial number can help you troubleshoot the computer and can also help you find the latest drivers and other updates for your computer. With desktop computer many OEM's list the information on the side of the computer, like the Hewlett Packard computer sticker shown to the right.

Laptop, netbook, and hybrid computers often have the model and serial number on the bottom of the computer. If you cannot find this information, manufacturers like Dell, HP, Lenovo, and Acer also have tools on the computer and websites to help identify your computer.

Operating system

The operating system is what allows your computer software to communicate with the computer hardware.

Windows start buttons

The most common operating system for these types of computers is Microsoft Windows, macOS, and Linux. You can quickly identify if the computer is running Windows if it has a Start button at the bottom-left corner of the screen. A macOS computer can be identified by the Apple menu at the top of the screen or the dock at the bottom of the screen.
