Widgets

widgets

widgets are virtual tools, programmed to share
dynamic information with users. Widgets can be web
based or desktop based. Various third-party sites
offer both types of widgets. When you create a web
widget, the widget provider generates an HTML code
which can be added to your web page code to display
the widget on your website. Desktop widgets are
applications which appear on your desktop and relay
dynamic information. Common desktop widgets
include clocks, calendars, current weather, scorecards etc.
In order to download and install desktop widgets, you would
require a widget engine. A widget engine is an
application with which one can execute and display widgets

Tablet PC

TABLET PC

Tablet PCs are mobile computers that
appear like a notebook or a slate.
Tablet PCs are meant to be mobile
and compact. They come equipped
with additional features like touchscreens
and related technologies
which enables the user to operate the
system with a stylus, a digital pen or
by mere touch instead of peripherals
like mice and keyboards.
Thus, Tablet PC is a general term
used for the pen computing technology.
The term "Tablet PC" was originally
coined by Bill Gates of Microsoft at the
2001 Comdex Conference.

SMART CARD


Smart Cards are pocket-sized cards made of plastic
which contain an embedded chip which contains encoded
data. They are also known as chip cards or integrated
circuit cards (ICC). The data is fed into the chip which
can be used either as an input (for authentication) or
output (like a punch card) with the help of specifically
designed applications. Some smart cards also have an
embedded hologram or other such mechanisms to circumvent
counterfeiting. The usage of smart cards has
risen considerably since it is a form of strong security authentication for
large companies and organizations
dealing with confidential matters.

Spyware

SPYWARE

Spyware is an application that
gathers information from a
person's computer without
their knowledge or consent. It
is also known as a spybot or
tracking software. Spyware
applications are usually used
to send spam to unsuspecting
users. The easiest way to install
a spyware on a users system is
through pop-up windows,
freeware applications or
screensaver packages.
Applications that install themselves
through advertisements
are called adware.
But since marketing companies
raised objections to
the term adware, the
Internet security companies
also refer to such
applications as "potentially
unwanted programs" or
PUP in short.

RESTORE POINT IN Windows Xp

Restore points are saved "snapshots" of the system data at a
given point of time created using the System Restore facility of
Windows. The System Restore feature can be used with Windows
ME, XP and Vista operating systems. The Windows Server family does
not support this feature. When youcreate a restore point,
your computer creates a backup
copy of all data, including the registry files and most drivers
at that particular time. It is wise to create a Restore Point
before you make any major change to your system to save
it from any potential system crashes. But remember that if
you restore your system to an earlier date and then decide to
roll back your system restore, any applications installed
between these two dates will be uninstalled automatically, but
the reqistery entries are not completely removed.
