CONCEPT
OF INTERNET IN
INTRANET Internet - is a network of computers worldwide
in scope that encompasses thousands
of other smaller networks. It is
known to the "network of networks". With a huge variety d computers
connected allows daily, millions of users around the world
exchange information. There is a large group of entities (companies,
organizations, academic bodies, research and government) and users
(researchers, students, professionals, entrepreneurs, employees, etc.)
connected, allowing the exchange of information and experience in the
most diverse topics, integration of processes, provision and use of
applications, databases, etc.. HOME - When your creation, the Internet
was used only for the exchange of information academic and military
entities by the American. DEVELOPMENTS - Today, the Internet is a
powerful way of integrating society, extremely useful, cost, which
opens new horizons for business, research, and even for everyday tasks,
such as access to banks, shops, recreation scheduling, etc.. OPERATION
- On the Internet, each computer has an identification, a single
number. This number serves as a kind of "electronic CPF." When a
computer needs to send an information to another, he finds his destiny
through this number, called IP address. The IP address is very
important because without it the computers of the Internet unable to
communicate. However, users generally do not need to worry about the ip
address of your computer, which is set up automatically when he
connects to the network via an ISP. IN BRAZIL Internet access is now
comparable, qualitatively, in the majority of countries. The
infrastructure Brazilian telecommunications has improved significantly
in recent years, allowing an access increasingly fast and reliable, by
values quite accessible to the range of people who have personal
computers. WHAT ARE UTILITIES? The best words to describe the
usefulness of the Internet are "communication" and "exchange
information". Using e-mail communicating the world faster than by does
and spending less than by telephone, to the home-pages, whose themes
and possibilities are virtually innumerable. To find information, there
are sites dedicated specifically to this. They are known as "search
engines", with large databases running behind. The "search engines" are
the best known internationally of yahoo! (Www.yahoo.com.br) and Google
(http://www.google.com.br/). The banking system has found the tool of
your dreams on the Internet in a trend to eliminate the need for
agencies and reduce their operating costs by encouraging the customer
to solve everything at home, by phone and online services
(home-banking). Internet / INTRANET - The higher the structure of the
company, the more difficult it is to obtain greater agility and work of
disseminating information internally, with customers and suppliers. The
connection between
intranets for different companies allows the
information flow through the production chain (the value chain). To
connect two intranets need some kind of physical connection. You can
use a simple cable network, if they are sufficiently close, or through
the phone line, using the Internet itself. Besides the physical
connection, it is necessary to use routers (routers) to separate the
traffic of the networks. Every computer on a INTRANET has an IP address
and a mask network. Using the masks network, it can tell if the other
computer with whom they wish to communicate this to him not on the same
network. If the destination is on the same computer network, he "pick"
the information directly from the network. Otherwise, a router "pick"
the information and be in charge of the par-despachá the network
correctly. INTRANET - is the application of Internet technology in a
closed network, usually corporate. In other words, users of the network
are to have services similar to those found on the Internet. But they
efetivametne has access to the Internet? That is, they can exchange
information with Internet users, not on your network? The intranets may
or may not be connected to the Internet. That is, they can be isolated
and only use internet technology to benefit its users, or can be part
of the Internet, with the able exchange information with computers
around the world. The connection of an intranet network to the Internet
is, technically speaking, very simple. As the internal network of
computers already use TCP / IP to communicate, they can easily exchange
information with other computers on the Internet. To do this, simply
possessing valid IP addresses on the Internet, not only in their
private networks. WHY SE DECIDED BY A INTRANET? The intranets are
already reality in major companies in the world, from the basic finding
that nearly all infrastructure (hardware and operating system) and
applications can be adapted to the technology Web Meanwhile, the
deployment of an intranet is an investment in a technology and is
therefore associated with a review of "x cost benefit" to reach a
decision favorable or not.
