welcome to another video from explaining
computers comm this time I'm going to
talk about internet developments known
as web 2.0 defining exactly what is
meant by web 2 is about as difficult as
nailing a jelly to a wall that said most
people agree that work to involve making
new and improved forms of online
connection between two or more people
between two or more online services or
between individual users and software
applications identifying these three
types of connection also enables us to
isolate the three key aspects of web 2
as being interpersonal computing web
services and software as a service
[Music]
interpersonal computing is about using
online technology to connect people to
each other in social networks or
business teams the key interpersonal
computing aspects of web 2 are therefore
things like social networking sites
wiki's blogs an online video examples of
these include Facebook and MySpace for
social networking Wikipedia blog
Croatian sites like blogger and video
hosts including Kaltura and YouTube all
of these sites allow anybody to add as
well as to access content to leave
messages and comments and to exchange
digital media including photographs and
video
[Music]
web services are components of online
functionality that can be plugs together
like a kind of digital Lego in order to
create an integrated online offering or
mashup
for example many companies use the web
service of a payment service provider
such as WorldPay or PayPal in order to
allow them to easily take credit card
payments online
this results in customers interacting
with two organizations that are
automatically interlinked via the
Internet that's another common example
web services are also frequently matched
together to integrate a map and related
data from one website into another for
example the property website Rightmove
integrates local information from about
my place which in turn obtains its maps
from Microsoft virtual earth and as a
third simple illustration anybody can
cut and paste a YouTube video embed link
to create a web page which is drawing
content from two sources and with
YouTube here providing the web service
of video hosting
the final key aspect of web 2 is
software-as-a-service
or SaaS this involves application of
functionality being offered directly
over the Internet in turn user data and
applications can then be accessed from
any internet-enabled computing device
for some years human resources and
project management applications have
been successfully offered over the
internet by companies including
employees and Clarizen however online
replacements for personal desktop
applications and now also available for
example google docs is an online word
processing spreadsheet and presentation
package available for free over the web
as an alternative Zoho also offers a
Microsoft Office compatible set of
online applications together with tools
for project management and other
business functions as yet another
example juice has launched a free online
desktop that also enables people to
access their files from anywhere and to
share them with others
many people are still dismissing web 2
as the latest marketing hype however
this is probably only because they are
unaware of the online service and
application delivery aspects and are
hence mistaking the concept is being
about no more than teenaged social
networking however in terms of both
business and computing over the next few
years
web 2 is likely to change the ways in
which many companies will link together
as well as the means by which many of us
will access our data and software
applications not least the purchase and
installation of expensive standalone
software is likely to reduce
substantially and in turn this will
impact on existing key industry players
like Microsoft Google and other web to
pioneer have shown a new business model
is becoming possible this involves
providing basic applications and
services for free and then charging a
small minority of users for service
support customization or Association one
challenge ahead is to see how robust and
more broadly applicable this web 2
business model may be
as web 2 takes hold many companies will
need to alter their online strategy the
old web woman business model was based
around building a great website and just
hoping that people would pay a visit
however in the web to age it is known
when most people go when they first log
on and this is - web 2 sites such as
myspace Facebook or YouTube inhabiting
these magnet cyber locations while
customers are known to be rather than
just expecting people to pay a companies
own website a visit
therefore has to become a key online
strategy hopefully this video has given
you an improved understanding of web 2
and its implications for more
information please see the web 2 pages
of explaining computers comm so that's
it for another video and I hope to talk
to you again very soon
