Our computer basic training for today will be focused on the different types of computers. In our last lesson, we talked about What Is Computer and the history of computers. Computers can be very large or very small. There are super-computers, very large computers with thousands of linked microprocessors that perform extremely complex calculations. Some computers are embedded in cars, TVs, stereo systems, calculators, and even household appliances.
Each computer design is built to perform specific tasks and functions. Desktop or personal computers are made to be used by one person at a time. In our computer basics lesson today, you will learn about different types of personal computers: desktops, laptops, handheld computers, and Tablet PCs.
Desktop computers:
Desktop computers (as the name suggests) are designed for use at a desk or table. They are generally larger and faster than other types of personal computers. Desktop computers are made up of separate components. The system unit is the major or main component in your computer system. Rectangular in shape it can sit on the desk or under. Other components also include the keyboard, mouse, speakers and monitor.
LAPTOP COMPUTERS:
Laptop computers are usually lightweight mobile PCs with an LCD display thin screen. Am sure you must have seen a lot of them, or even using one yourself for your computer basic training. They are sometimes called notebook computers because they can be used instead of a notebook with paper. Laptops can also operate on batteries, so you can take them anywhere you need to work. Unlike desktops, laptops are completely self-contained. The laptop folds and closes like a book. Hence making it easy for you to learn how to use computer faster any where you go.
HANDHELD COMPUTERS:
Handheld computers, also called personal digital assistants (PDAs), are battery-powered computers like Blackberry's. Handheld computers are not as fast as desktops or laptops, handhelds are handy for making appointments, keeping track of addresses and phone numbers, and playing games.
Some handhelds have more advanced features, like making telephone calls or getting on the Internet. Instead of a keyboard, handheld computers or PDA's have touch screens that you use with your finger or a stylus, which looks a lot like a pen without ink. So you now know the answer to your question "What Is Computer"? Let's continue with our computer basics training!
TABLET COMPUTERS
Do you know what tablet computers are? Tablet Personal Computers are mobile PCs that combine features of laptops and handhelds. Like laptop computers, Tablet computers are very powerful, fast and have a screen like a tablet. Like handhelds, Tablets can allow you to make notes or draw pictures directly on the screen, usually with a tablet pen instead of a stylus. Do you know that tablets can also transform your handwriting into typed text? Some Tablet PCs have a screen that swivels and unfolds to reveal a keyboard under the computer.
