The Internet:
A Nursing Resource
Nursing Informatics
What is Internet?

Network of computer networks

It is filled with over-growing number of sources of
healthcare information.

It changed the way on how they interact with their
patients. Not just assessing health status and teaching
but are correcting misinformation, reassuring patients
who have misinterpreted what they have found, and
answering questions about new trends and treatments.

It is a constant source of up-to-date professional
information.

Use by nurses to network to all colleagues, sharing their
knowledge and learning from each other.
History of the Internet

ARPA(Advanced Research Project
Agency)
 Pres.
Eisonhower
 Work with RAND Corp. think how to solve the
problem of how U.S. authorities could
communicate after the nuclear war
 Packet switching invented by Paul Barran
Who controls the Internet?
The Internet itself has no owners, censors,
bosses, board of directors or stockholders.
 In principle, any computer or networks that
obeys the protocols, which are technical,
not social or political, can be an equal
player.

ISOC

Is the overall organizing force, an international, nonprofit,
professional membership organization with no
governmental allegiances.

It comprised over 150 organizations and 16000
individual members that represent over 180 nations.

The society works to maintain standards, develop public
policy, provide education and increase membership.
The Technology Behind the
Internet

Protocol – just an agreed on format for doing something.

On the Internet, protocols determine how data will be transmitted
between two devices, the type of error checking that will be
performed, how data compression is accomplished, how sending
computer will signal that it has finished sending a message, and
how receiving computer will signal that it has received message.

As user, your concern should be that the software and hardware
you are using supports the protocols of the computer or device
with which you wish to have computer communicate.
Protocols

TCP and IP are the main protocols on which the
functioning of the Internet is dependent.

TCP allows computers to connect to a network and
exchange data. This protocol carries out the task of
breaking messages into small packets.
IP is a lower level protocol, which is responsible for
making decisions about these packets and routing them.
HTTP – protocols that support WWW.
FTP – which permits users to send all types of electronic
files over the Internet
Telnet – allows users to access a distant computer as
though they were sitting in front of it.



DNS
Pioneer in the protocols that allow DNS to
work was Paul Mockapetris
 It permits us to give globally unique names
to networks and computers.
 Benefits :

 Name
is easier to remember
 Name allows to change physical location that
is transparent to the user.
DNS
A series of characters makes up each
domain name.
 These strings, called “labels” are
separated by dots.
 The right-most label in a domain name is
referred to as its “top-level domain” (TLD)

Use of the Internet-Then and
Now

FTP
 The
method used by early Internauts to upload files to
and download files from distant computers
 Used the Internet’s TCP/IP protocols for the transfer
of data


Uploading
Downloading
Use of the Internet-Then and
Now

Telnet
A
terminal emulation program that is part of the
TCP/IP protocols
 Allows a connecting computer to behave like a
terminal for a distant computer regardless of the type
of computer
 A log in and password are required to begin a Telnet
session
 Often used to control Web servers remotely
Use of the Internet-Then and
Now

Usenet News and Online Forums
 Discussion


groups on the Internet
Online forums are often set up by organizations
to allow members, or anyone, depending on how
the forum is organized, to share ideas.
Forums were originally accessed by Telnet but
today they are usually accessed through a web
site.
