A portable computer that is small enough to be held in one's hand. Although extremely convenient to carry, handheld computers have not replaced notebook computers because of their small keyoards and screens. The most popular hand-held computers are those that are specifically designed to provide PIM (personal information manager) functions, such as a calender and address book. The most popular are IPAQ and Palm.
|
Handheld Computer (Pocket PC)
|
|
|
The technique by which a computer system can recognize characters and other symbols written by hand. In theory, handwriting recognition should free us from our keyboards, allowing us to write and draw in a more natural way. It is considered one of the key technologies that will determine the ultimate success or failure of PDAs and other hand-held devices

|
Laptop Computer
|
|
|
A type of display used in many portable computers and flat screen monitors. LCD displays utilize two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light.

|
An extremely lightweight personal comoputer. Notebook computers typically weigh less than 6 pounds and are small enough to fit easily in a briefcase. Aside from size, the principal difference between a notebook computer and a personal computer is the display screen. Notebook computers use a variety of techniques, known as flat-panel technologies, to produce a lightweight and non-bulky display screen.

|
The field of computer science that deals with designing computer systems that can recognize spoken words. Note that voice recognition implies only that the computer can take dictation, not that it understands what is being said.
|
Speech Recognition
|
|
|
A type of notebook computer that has LCD screen on which the user can write using a special-purpose pen, or sylus. The handwriting is digitized and can be converted to standard text through handwriting recognition, or it can remain as handwrtten text. Tablet PCs also typically have a keyboard and/or a mouse for input
|
Tablet PC
|
|
|
An input device that enables the user to enter drawings and sketches into a computer. A digitizing tablet consists of an electronic tablet and a cursor or pen. A cursor (also called a puck) is similar to a mouse, except that it has a window with cross hairs for pinpoint placement, and it can have as many as 16 buttons. A pen (also called stylus) looks like a simple ballpoint pen but uses an electronic head instead of ink. The tablet contains electronics tha enable it to detect movement of the cursor or pen and translate the moements into digital signals that it sends to the computer.
