We human being have a crave for information psychologically so we use the internet to gain knowledge.
The Internet allows greater flexibility in working hours and location,
especially with the spread of unmetered high-speed connections. The
Internet can be accessed almost anywhere by numerous means, including
through mobile Internet devices. Mobile phones, datacards, handheld game consoles and cellular routers allow users to connect to the Internet wirelessly.
Within the limitations imposed by small screens and other limited
facilities of such pocket-sized devices, the services of the Internet,
including email and the web, may be available. Service providers may
restrict the services offered and mobile data charges may be
significantly higher than other access methods.
Educational material at all levels from pre-school to post-doctoral is
available from websites. Examples range from CBeebies, through school
and high-school revision guides, virtual universities, to access to
top-end scholarly literature through the likes of Google Scholar. For
distance education, help with homework and other assignments,
self-guided learning, whiling away spare time, or just looking up more
detail on an interesting fact, it has never been easier for people to
access educational information at any level from anywhere. The Internet
in general and the World Wide Web in particular are important enablers
of both formal and informal education.
The low cost and nearly instantaneous sharing of ideas, knowledge, and
skills has made collaborative work dramatically easier, with the help of
collaborative software. Not only can a group cheaply communicate and
share ideas but the wide reach of the Internet allows such groups more
easily to form. An example of this is the free software movement, which
has produced, among other things, Linux, Mozilla Firefox, and
OpenOffice.org. Internet chat, whether in the form of an IRC chat room
or channel, via an instant messaging system, or a social networking
website, allows colleagues to stay in touch in a very convenient way
when working at their computers during the day. Messages can be
exchanged even more quickly and conveniently than via email. These
systems may allow files to be exchanged, drawings and images to be
shared, or voice and video contact between team members.
Content management systems allow collaborating teams to work on shared
sets of documents simultaneously without accidentally destroying each
other's work. Business and project teams can share calendars as well as
documents and other information. Such collaboration occurs in a wide
variety of areas including scientific research, software development,
conference planning, political activism and creative writing. Social and
political collaboration is also becoming more widespread as both
Internet access and computer literacy spread.
The Internet allows computer users to remotely access other computers
and information stores easily, wherever they may be. They may do this
with or without computer security, i.e. authentication and encryption
technologies, depending on the requirements. This is encouraging new
ways of working from home, collaboration and information sharing in many
industries. An accountant sitting at home can audit the books of a
company based in another country, on a server situated in a third
country that is remotely maintained by IT specialists in a fourth. These
accounts could have been created by home-working bookkeepers, in other
remote locations, based on information emailed to them from offices all
over the world. Some of these things were possible before the widespread
use of the Internet, but the cost of private leased lines would have
made many of them infeasible in practice. An office worker away from
their desk, perhaps on the other side of the world on a business trip or
a holiday, can access their emails, access their data using cloud
computing, or open a remote desktop session into their office PC using a
secure Virtual Private Network (VPN) connection on the Internet. This
can give the worker complete access to all of their normal files and
data, including email and other applications, while away from the
office. This concept has been referred to among system administrators as
the Virtual Private Nightmare,[36] because it extends the secure
perimeter of a corporate network into remote locations and its
employees' homes.
