D
DC Jack:
Allows you to connect to external power with the supplied
AC adapter.
Device Driver:
A software routine that links a peripheral device to
the operating system. It acts like a translator between
a device and the applications that use it. Each device
has its own set of specialized commands known only to
its driver. In contrast, most applications access devices
by using high-level, generic commands. The driver accepts
these generic and translates them into the low-level
specialized commands required by the device.

PIM (Personal Information
Manager): a type of software application
- a given on PDA devices and many mobile phones - that
allows you to enter text for any purpose and retrieve
it based on any of the words you typed in. PIMs vary
widely, but all of them attempt to provide methods for
managing information the way you use it on a daily basis.
Typical features include a telephone list, calendar,
scheduler, reminder and calculation functions.
Pocket Word, Pocket
Excel, Pocket Explorer, Pocket Outlook: You
will notice a lot of Windows CE applications with the
"pocket" designation. In general, this means that the
application is a slimmed-down version of the desktop
application you generally use. For example, Pocket Word
has a similar look and feel to Microsoft Word; however,
Pocket Word has fewer features to let it run in the
smaller space provided by the Windows CE operating system.
Port: A
Port is part of the PC that is used for passing data
in and out of a computing device. This is normally located
on the back of the PC. The port can be a Serial Port
- data is sent/received one bit at a time through a
cable containing a single wire, or a Parallel port where
the data is sent/received through a cable containing
several pieces of wire so that more than one bit at
a time can be processed. Also referred to as the I/O
Port.

Memory): the PC's primary storage area, used
to write, store and retrieve information and program
instructions which are then passed to the CPU for processing.
The type of RAM used affects performance as the information
stored here has to be refreshed many times per second
by the processor. Manufacturers are continually coming
up with new designs to provide the fastest possible
access times at the lowest possible cost.
ROM (Read Only Memory):
an integrated circuit chip containing programs and data
that can be accessed and read but cannot be modified.
Top
S
SDRAM (Synchronous
DRAM): a type of DRAM designed to deliver
bursts of data at very high speeds using automatic addressing,

and Advanced RISC Machines (ARM). In 1997, Intel acquired
Digital's chip manufacturing facilities and continues
to make the Alpha and StrongARM chips.
Stylus:
A stylus is a pointing object that you use to navigate
on the screen. It works similarly to a mouse or trackball.
Synchronous:
Refers to events that are synchronized, or co-ordinated,
in time. Communication within a computer is usually
synchronous and is governed by the microprocessor clock.
Signals along the bus, for example, can occur only at
specific points in the clock cycle.
Top
T
TCP/IP (Transmission
Control Protocol/Internet Protocol): the
communications protocol used by UNIX systems and the
Internet. TCP checks for lost packets, puts the data
from multiple packets into the correct order and requests
that missing or damaged packets be resent.
Top
U
USB (Universal Serial
Bus): Intel's new standard for attaching
peripherals to PCs. Designed for low to medium data
throughput, it should remove the need to install many
devices internally once it gains widespread acceptance.

WAN (Wide Area Network):
a geographically dispersed network formed by linking
several computers or local area networks (LANs) together
over long distances, usually using leased long-distance
lines. WANs can connect systems across town, in different
cities, or in different regions of the world.
Windows CE:
Windows CE is based on the Microsoft Windows
operating system but is designed for including or embedding
in mobile and other space-constrained devices. Although
Microsoft does not explain the "CE," it is reported
to have originally stood for "Consumer Electronics."
Windows CE is a 32-bit multitasking, multithreaded operating
system. Microsoft emphasizes that the system was "built
from scratch" while taking advantage of Windows architectural
concepts and interfaces. Microsoft argues that Windows
desktop system users will find that products with Windows
CE provide a familiar user interface.
