Transcript Presentation to End Users on Internet Use

The SAIC
Operation 54 Network
and the Internet
Overview
• The purpose of this brown bag training session is
to provide you with an introduction to the Internet
and to solicit interest into use of the Internet as a
research tool for Operation 54 network users.
• This brown bag will not train you to utilize the
Internet software.
• Further brown bag sessions will be held on the
software applications utilized for Internet searches.
• The next step after attending this brown bag would
be to get setup to access the Internet. Put your
name on the sign-up sheet.
Internet History
(extremely short)
• The Internet is a loose collection of millions of
computers at thousands of sites around the world
whose users can pass along information and share
files no matter which of those computers they're
using.
• What is now the Internet began as an experiment
in the late 1960s to test the possibility of creating a
disaster-proof nationwide computer system where
scientists and military personnel could share
messages and data no matter where they were.
Introduction
• There are four information source destinations
available to you on the Internet through the
Operation54 network:
–
–
–
–
FTP servers
Gopher servers
WWW servers, and
telnet servers.
• These information sources are accessed through
the Operation standard Internet software suite.
The Operation 54
Internet Software
• Once you are setup with the Operation54 Internet
software suite, you can utilize the icons and
resulting applications in the 'Internet' group in your
Program Manager main window.
The Operation 54
Internet Software
• The software packages include:
Mosaic
Gopher
FTP
telnet
Trumpet (tcp/ip)
• You won’t actually run the Trumpet software, it is
automatically loaded by the other applications to
allow Internet communications.
How you are
connected
• Your access to the Internet is provided as a result
of having access to the Operation54 network.
OP54
CerfNet
Internet
• The Operation54 network is connected via a
'bridge' to the SAICnet which in turn is connected
to CerfNet and then the Internet.
the TCP/IP
network protocol
• Your computer must be setup to run the TCP/IP
network protocol software which provides
communication capability onto the Internet.
• You cannot setup yourself for access to the
Internet, it must be done by a network
representative.
• The TCP/IP protocol allows you
to communicate on the Internet
and the software package that we
utilize for this purpose is called Trumpet.
telnet sites
• A terminal emulation protocol and program that
allows users to login to a computer on the Internet.
• Users usually login as 'anonymous'.
• The finance department within the Operation
‘telnets’ to the SAIC McLean VAX for their day-today operations.
• This is the simplest and least robust of the Internet
search tools available.
telnet
software & examples
• Our network client (software package)
used to access information on
telnet sites is called telnet.
• Examples of telnet sites:
– fedworld.gov
– lehign.edu
FEDWORLD
Lehigh University
FTP sites
• FTP servers on the Internet store a variety of files
and allow users to download them using a program
of the same name.
• You will usually need to know the exact location of
a file on an FTP server in order to download the
file.
• For example, the files required to run the FTP
software were downloaded from the 'ftp.usma.edu'
server in the '/pub/msdos/winwock.files' directory.
FTP
software & examples
• Our network client (software package)
used to access information on
FTP sites is called FTP.
• FTP is a protocol that describes file transfer
between a host and a remote computer and also
refers to programs based on this protocol.
• Examples of FTP sites:
– ftp.ncts.navy.mil
– ftp.microsoft.com
United States Navy
Microsoft
Gopher sites
• Server sites used as the destination for Internet
searches.
• A software tool for conducting text searches on the
Internet.
• A search tool that presents information in a
hierarchical menu system somewhat like a table of
contents.
• Gopher searches are mostly limited to text.
• Users can 'jump' from one Gopher server to
another while online.
Gopher
software & examples
• Our network client (software package)
used to access information on
Gopher sites is called Gopher.
• The Mosaic program can also be used
to conduct Gopher searches.
• Examples of Gopher sites:
– stc.nato.int
– marvel.loc.gov
– gopher.senate.gov
NATO
The Library of Congress
US Senate
the World Wide
Web (WWW)
• A network of servers that uses hypertext links to
find and access files.
• Graphics can also be included in the documents.
• WWW servers are accessed through their "home
pages" that are basically function as the door into a
web site.
• Users can 'jump' from one web site to another
while online.
WWW
software & examples
• Our network client (software package)
used to access information on the
WWW is called Mosaic.
• Examples of Web sites:
–
–
–
–
–
www.ic.gov
www.btg.com
www.whitehouse.gov
www.fedworld.gov
www.saic.com
the CIA
Jane’s Defense

Conclusion &
Questions
• By now you should be convinced that the Internet
and the related software applications for access
are tools that you can utilize in your everyday work.
• To restate, this was an overview of the Internet and
the access provided by the Operation network.
• The next brown bag training session will be on the
use of the Gopher software.
• There will also be a brown bag on Internet email.
