I am new in this forum and also in electronic. Last Friday my teacher ask me to write an assignment about " Difference between Internet and Intranet from the network engineering points of view". I don't know what to do. Pls give me some suggestion.
Sorry for my English, I am poor in this.

Looking forward to get some idea

internet is the global network, and intranet is a private network not connected to the internet. its sort of a private little network, but usually with a server and everything to make it look like a little version of the internet

intranet
An intranet is a local area network (LAN) used internally in an organisation to facilitate communication and access to information that is sometimes access-restricted. Sometimes the term refers only to the most visible service, the internal web site. 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 email. There is often an attempt to use internet technologies to provide new interfaces with corporate 'legacy' data and information systems.

There does not necessarily have to be any access from the organisations's internal network to the internet itself. Where there is, there will be a firewall with a gateway through which all access takes place. Traffic going through the gateway can be monitored by the organisation's security department. This means that organisations that allow their staff internet access can normally determine which internet web sites are being viewed, block access to specific sites they don't want them to see (such as pornographic sex sites), and even trace offenders who persistently attempt to view them. They can also block certain types of web content (such as objects) which they consider a particular security risk.

Where external email access is provided, known sources of spam and specific types of email attachment can be blocked by the organisation. It should also be noted that emails sent and received this way can be required to be produced by the organisation in the event of legal action against it by a third party.

Internet computers use the TCP/IP communications protocol. There are more than 100 million hosts on the Internet, a host being a mainframe or medium to high-end server that is always online via TCP/IP. The Internet is also connected to non-TCP/IP networks worldwide through gateways that convert TCP/IP into other protocols.


Life Before the Web

Before the Web and the graphics-based Web browser, the Internet was accessed from Unix terminals by academicians and scientists using command-driven Unix utilities. These utilities are still used; however, today, they reside in Windows, Mac and Linux machines as well. For example, an FTP program allows files to be uploaded and downloaded, and the Archie utility provides listings of these files. Telnet is a terminal emulation program that lets you log onto a computer on the Internet and run a program. Gopher provides hierarchical menus describing Internet files (not just file names), and Veronica lets you search Gopher sites. See FTP, Archie, Telnet, Gopher and Veronica.


The Next Internet

Ironically, some of the original academic and scientific users of the Internet have developed their own Internet once again. Internet2 is a high-speed academic research network that was started in much the same fashion as the original Internet (see Internet2). See Web vs. Internet, World Wide Web, how to search the Web, intranet, NAP, hot topics and trends, IAB, information superhighway and online services.



Modest Beginnings
These four nodes were drawn in 1969 showing the University of California at Berkeley and Los Angeles, SRI International and the University of Utah. This modest network diagram was the beginning of the ARPAnet and eventually the Internet. (Image courtesy of The Computer Museum History Center, www.historycenter.org)



How the Internet Is Connected
Small Internet service providers (ISPs) hook into regional ISPs, which link into major backbones that traverse the U.S. This diagram is conceptual because ISPs often span county and state lines.
