Answer 1

INTERNET

The Internet is the worldwide, publicly accessible network of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked Web pages and other documents of the World Wide Web.

INTRANET

An intranet is a private computer network that uses Internet protocols, network connectivity, and possibly the public telecommunication system to securely share part of an organization's information or operations with its employees. Sometimes the term refers only to the most visible service, the internal website. The same concepts and technologies of the Internet such as clients and servers running on the Internet protocol suite are used to build an intranet. HTTP and other Internet protocols are commonly used as well, especially FTP and e-mail. There is often an attempt to use Internet technologies to provide new interfaces with corporate 'legacy' data and information systems.

Briefly, an intranet can be understood as "a private version of the Internet", or as a version of the internet confined to an organization.

EXTRANET

An extranet is a private network that uses Internet protocols, network connectivity, and possibly the public telecommunication system to securely share part of an organization's information or operations with suppliers, vendors, partners, customers or other businesses. An extranet can be viewed as part of a company's Intranet that is extended to users outside the company (eg: normally over the Internet). It has also been described as a "state of mind" in which the Internet is perceived as a way to do business with other companies as well as to sell products to customers.

Briefly, an extranet can be understood as "a private internet over the Internet".

An argument has been made that "extranet" is just a buzzword for describing what institutions have been doing for decades, that is, interconnecting to each other to create private networks for sharing information. Although, even if this argument is valid, the term "extranet" is still applies and can be used in order to elimate the use of the above description.

Another very common use of the term "extranet" is to designate the "private part" of a website, where "registered users" can navigate, enabled by authentication mechanisms on a "login page".

Hope this solves your question.

Answer 2

Internet: The world-wide network of computers through which we're all sharing information. Example: Yahoo! Answers is an internet website.

Intranet: An organization's internal network, commonly using many of the same services as the internet such as web and email. The difference is it is only available when connected to that organization's network. Example: A networked system for placing sales orders at a retail store, which can only be accessed from computers inside the store.

Extranet: The bridge between the above two -- features provided by the organization's intranet which are also available on the internet, usually via an encrypted connection for security. Example: Warehouses which have their inventory systems linked so they can all check each others' current inventory. Only those warehouses have access to the system.

Hope this has helped clarify.

Both are usually appeals for things you ask for selfishly or ought to take care of yourself. The Lottery costs you a around 70 cents for each dollar of return on the long term, and it has only materialistic benefits. Prayer doesn t cost you anything, the results are based on the request s agreement with the perfect divine plan, and it can have eternal benefits. The Lottery will break your bank account, but investing in prayer builds your heavenly account -- if you have accepted the deposit that s waiting to take you out of the red.
