A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. You may already know that you can use a computer to type documents, send email, play games, and browse the Web. You can also use it to edit or create spreadsheets, presentations, and even videos.
Watch the video below to learn about different types of computers.
Hardware vs. software
Before we talk about different types of computers, let's talk about two things all computers have in common: hardware and software.
- Hardware is any part of your computer that has a physical structure, such as the keyboard or mouse. It also includes all of the computer's internal parts.
- Software is any set of instructions that tells the hardware what to do and how to do it. Examples include web browsers, games, and word processors.
What are the different types of computers?
When most people hear the word computer, they think of a personal computer such as a desktop or laptop. However, computers come in many shapes and sizes.
Desktop computers
Designed to be placed on a desk, these are typically made up of a few different parts, including the computer case, monitor, keyboard, and mouse.
Laptop computers
Commonly called a laptop, these are battery-powered and more portable than desktops, allowing you to use them almost anywhere.
Tablet computers
Tablets are handheld computers that are even more portable than laptops. They use a touch-sensitive screen for typing and navigation instead of a physical keyboard.
Servers
A server is a computer that "serves up" information to other computers on a network. Whenever you use the Internet, the web pages you see are stored on a server.
Other types of computers
Many of today's electronics are basically specialized computers:
- Smartphones: Cell phones that can browse the Internet and play games.
- Wearables: Devices like fitness trackers and smartwatches designed to be worn all day.
- Game consoles: Specialized computers used for playing video games on your TV.
- TVs: Many TVs now include apps that let you stream online content directly.
PCs and Macs
Personal computers come in two main styles: PC and Mac. Both are fully functional, but they have a different look and feel.
PCs
This type typically includes the Microsoft Windows operating system. It began with the original IBM PC in 1981 and is currently the most common type of personal computer.
Macs
Introduced in 1984, the Macintosh was the first widely sold computer with a graphical user interface (GUI). All Macs are made by Apple and use the macOS operating system.
