***1 An Introduction to Tablet Computer Ladies and gentlemen, good evening!Today, I’d like to give you a brief introduction of tablet computer.As we all know that tablet computer is becoming more and more popular, especially among young people.So what is tablet computer?

A tablet computer, or simply tablet, is a complete mobile computer, larger than a mobile phone or personal digital aistant, integrated into a flat touch screen and primarily operated by touching the screen.It often uses an onscreen virtual keyboard or a digital pen rather than a physical keyboard.A significant trait to define whether a tablet computer can be regarded as a personal computer is the ability for the final user to install arbitrary or self-developed software.Now we have got a general idea about tablet computer, but what are the main features of a tablet computer? There are three main characteristics of a tablet computer.The first one is powerful.Tablet computer can run almost all PC applications compatibly with Windows XP, plus the applications which specifically target tablet computer.On connectivity side, besides the built-in wirele support, Tablet computers can also be placed into a docking station at a desk to support a large monitor, network connection, keyboard, mouse, and other peripherals.The second one is mobility.The tablet computer comes in two basic forms, the “convertible” with an integrated keyboard, and the ultra-mobile “pure tablet”.All tablet computers will be very light — ranging from 2 to 3 pounds.Combined with wirele network support, tablet computer gives you greater mobility and immediate acce to the full power of your PC.The third one is natural interaction with computer.This means using a digital pen and the input panel utility, you can write directly on the screen and save your notes in your own handwriting or convert them to typed text for input into other applications.Speech recognition is an integral component of every tablet computer, allowing 0804班
