types of computers.

Desktop computers

Many people use desktop computers at work, home, school, or the library. They can be small, medium, or large in style, and they usually sit on a desk. Once you add a monitor, mouse, and keyboard, you have what is typically known as a desktop computer.

Most desktop computers are easy to upgrade and expand or add new parts. Another benefit of desktop computers is the cost. If you compare a desktop and a laptop with the same features, you will most likely find that the desktop computer is priced lower.  

    

Laptop computers

The second type of computer you may be familiar with is a laptop computer, or a laptop. Laptops are battery- or AC-powered personal computers that are more portable than desktop computers, allowing you to use them almost anywhere.

Because a laptop is smaller than a desktop, it's more difficult to access its internal components. This means you may not be able to upgrade them as easily as a desktop. However, it's usually possible to add more RAM or a larger hard drive.

Other types of computers

Today, there are many everyday devices that are basically specialized computers, even though we don't always think of them as computers. Here are a few common examples:

• Tablet computers: These use a touch-sensitive screen for typing and navigation. Because they don't require a keyboard or mouse, tablet computers are even more portable than laptops. The iPad is an example of a tablet computer.
• Mobile phones: Many mobile phones can do a lot of things computers can do, such as browsing the Internet and playing games. These phones are often called smartphones.
• Game consoles: A game console is a specialized kind of computer that is used for playing video games. Although they are not as fully featured as desktop computers, many newer consoles, such as the Nintendo Wii, allow you to perform non gaming tasks like browsing the Web.
• TVs: Many TVs now include applications (or apps) that let you access various types of online content. For example, you can view your Facebook news feed or watch streaming movies on Netflix.

PCs and Macs

Personal computers come in two main styles: PC and Mac. Both styles are fully functional, but they do have a different look and feel, and many people prefer one or the other.

 

• PC: This type of computer began with the original IBM PC that was introduced in 1981. Other companies began to create similar computers, which were called IBM PC Compatible (often shortened to PC). Today, this is the most common type of personal computer, and it typically includes the Microsoft Windows operating system.
• Mac: The Macintosh computer was introduced in 1984, and it was the first widely sold personal computer with a Graphical User Interface, or GUI (pronounced gooey). All Macs are made by one company, Apple Inc., and they almost always use the Mac OS X operating system..
