The document defines and describes several types of computers: - Desktop computers are high-end PCs for technical use, connected to a network with multi-user operating systems. They have a horizontally oriented case with separate screens and keyboards. All-in-one PCs combine the monitor and case in a single unit. - Notebooks and mini notebooks are small, portable laptop computers for general computing and web access. Tablet PCs have touchscreens that allow input with a pen or finger instead of a keyboard/mouse. - Media centers combine the functions of a PC and digital video recorder, connecting to a TV for media playback, recording, and receiving TV signals. PDAs are handheld computers running Windows Mobile.

2.  a high-end personal computer designed for technical or
scientific applications. Intended primarily to be used by one
person at a time, they are commonly connected to a local area
network and run multi-user operating systems.

3.  'desktop' refers specifically to a horizontally-oriented case,
usually intended to have the display screen placed on top to save
space on the desk top. Most modern desktop computers have
separate screens and keyboards.

4.  also known as all-in-one PCs
is a subtype of desktop computers, which combine the monitor
and case of the computer within a single unit.

5. A subtype of desktops
 it was introduced by Intel in February 2008 to describe low-cost,
lean-function, desktop computers.

6.  also called a notebook computer or sometimes a notebook
is a small personal computer designed for portability.

7.  also called mini notebooks or subnotebooks
are a rapidly evolving category of small, light and inexpensive
laptop computers suited for general computing and accessing
web-based applications; they are often marketed as "companion
devices," that is, to augment a user's other computer access.

8. is a notebook or slate-shaped mobile computer
first introduced by Pen computing in the early 90s with their
Pen Go Tablet Computer and popularized by Microsoft. Its touch
screen or graphics tablet/screen hybrid technology allows the
user to operate the computer with a stylus or digital pen, or a
fingertip, instead of a keyboard or mouse.

9.  is a specification for a small form factor of tablet PCs. It was
developed as a joint development exercise by Microsoft, Intel,
and Samsung, among others

10.  is a convergence device that combines the functions of a personal
computer and a digital video recorder. It is connected to a television
or a television-sized computer display and is often used as a digital
photo, music, video player, TV receiver and digital video recorder.

11.  is a hardware specification for a handheld-sized computer
(personal digital assistant) that runs the Microsoft Windows
Mobile operating system. It may have the capability to run an
alternative operating system like Net BSD or Linux. It has many
of the capabilities of modern desktop PCs.
