5.1 Introduction One of the original laptops was the GRiD Compass 1101. It was used by astronauts on space missions in the early 1980s. It weighed (5 kg) and cost US $8,000 - $10,000! Laptops today often weigh less than one-half the weight and cost less than one-third the price of the GRiD. The compact design, convenience, and evolving technology of laptops have made them as popular as desktops. Laptops, Personal Digital Assistants (PDAs), and smartphones are becoming more popular as their prices decrease and technology continues to progress. 5.2 Describe laptops and other portable devices Laptops Early laptops were heavy and expensive. Today, laptops are very popular because advances in technology have resulted in laptops that cost less, weigh less, and have improved capabilities. Many laptops can be configured with an additional video port, a FireWire port, an infrared port, or an integrated camera.
PDAs and Smartphones PDAs and smartphones are examples of portable, handheld devices that are becoming more popular. PDAs offer features such as games, web surfing, e-mail, instant messaging, and many other features offered by PCs. Smartphones are cell phones with many built-in PDA capabilities. PDAs and smartphones can run some of the same software as laptops. 5.2.1 Identify some common uses of laptops The most significant feature of a laptop is its compact size. The design of the laptop places the keyboard, screen, and internal components into a small, portable case. Another popular feature of the laptop is its portability. A rechargeable battery allows the laptop to function when it is disconnected from an AC power source.
