Palmtop and handheld computers - Программирование

A palmtop, or handheld, computer isn’t really as much a computer as it is a data-gathering device. Basically, the system is about the size of a pad of paper, with a large screen and a few handy buttons, as shown in Figure 3-7. A stylus is used to write directly on the screen, which serves as both the display and the input device.

The palmtop computer is more ideally a replacement for the old organizer.

It’s good for taking notes, scheduling, doodling, and playing games, plus some versions can play music or even take digital pictures. But, overall, this type of computer works best as an on-the-go extension of a desktop computer system.

- The most popular palmtop device is the Palm handheld computer. This fact leads some folks to refer to this category as “Palm” computers, although many other handheld computer brands, makes, and models are available.

- Unlike other, earlier small computers, the modern handheld system is revolutionary because it doesn’t pretend to be a smaller version of a fullon computer. It serves as a notepad, address book, and scheduler, and it has lots of unique software. The handheld system does specialized tasks and does them well.

- Handheld computers can work with both Macintosh and PC computers, making them an ideal supplement to a desktop system.

Summing- Up

a) Read the extract from Dan Gooking’s book ‘Buying a Computer for Dummies’. Give a good translation of the extract, try to keep to the style of the author:

“Just Tell Me Which Type of Computer I Need!”

Sorry — can’t do that. Everyone is different, so everyone needs something a little different in their computers. Although it’s true that you could get by with just about any computer, why settle for something less than what you need? This book shows you how to find a computer especially for you.

Think of it like a car. You may say “I want a new car.” Which type of car? A sedan? A truck? How big of an engine do you want? What about good gas mileage? Do you want to pay extra for power seats or heated outside mirrors? And — most important — what color do you want? Computers are more complex than cars, so you have even more personal decisions to make.
