2.  Whatis Networking?
 A network is a set of technologies – includinghardware, software and
media – that can be used to connectcomputers together, enabling
them to communicate, exchange information andshare resources in
real time.
 The Internet is generallydefinedas a global network connecting
millions of computers. More than 190 countries are linked into
exchanges of data, news and opinions.
 Networks are used almost everywhere. Withoutthem we would not
have the internetor be able to log into the computers at school/work.
Many tasks that we use a computer for wouldbecome almost
impossible.
CommonTypesof Networks
 Local Area Networks ( LANs )
 Wide Area Networks ( WANs )
 Hybrid Networks
 Campus Area Networks ( CANs )
 Metropolitan Area Networks ( MANs )
 Home Area Networks ( HANs )

3. If we want to understandthe different types of networks and how
they operate, we need to know how networks are structured.
There have three important topics for knowingthe networking
system.
o ISP
o IP
o TCP
 IP
 InternetProtocol
 The method which information is sent between any two computers
on the Internet.
 IP addresses are the backbone of networking, There are many levels
and classes of IP addresses and also some are even reserved for
special use.
 The numbers in an IP Address go from 0-255.
 Example:
IP ADDRESS

 Local IP Address (Auburn Secure)
 10.30.18.21
 ISP
 InternetService Provider
 Refers to a company that provides Internet services, including
personal and business access to the Internet
 Examples:
 Windstream
 AT & T
 Time Warner
 Verizon
 TCP
 Transmission Control Protocol

5.  is a set of rules used along with the Internet Protocol to send data in
the form of message units between computers over the internet
 a protocol developedfor the internet to get data from one network
device to another;
 Whatis Internet?
 The Internet is the global system of interconnectedcomputer
networks that use the Internet protocol suite (TCP/IP) to link devices
worldwide.
 Not confiningitself to any particular definition, the Internet can be
defined as the wiredor wireless mode of communication through
which one can receive, transmit information that can be used for
single or multiple operations.
The Internet’sMajorServices
The internet acts as a carrier for several differentservices, each with its own
distinct features and purposes. The most commonly used Internet services
are
o The World Wide Web
o Electronic Mail

6. o News
o File Transfer Protocol
o Chat
o Online Services
o Peer-to-peer Services
o Instant Messaging
To use any of these services, we need a computer that is connected to
the Internet.
Importanceof Internetin ModernLife
Today, the internet is one of the most powerful tools throughout the world
everywhere you take. And in today’s society, the internet is a major part of
everyone’s life. Whether it is school, business, on entertainment, it has
influencedus immensely.
Some Important Parts:
 Shopping on mind? Just log on to the Internet
 Online study, training& education – A boon for Students
 Bankingat a click – Online-Banking
 Latest Softwares on the go
 News and Live Entertainmenton the web
 Research

7.  Online Booking
 Blogging
 Job-hunting
These all are the most important things that we need in our everyday life.
So, without internetwe can’t make a move in our modern life today.
WorldWideWeb(WWW)
The World Wide Web (WWW) is combination of all resources and users on
the Internet that are using the Hypertext Transfer Protocol (HTTP).
A broader definition comes from the WorldWide Web Consortium(W3C):
"The WorldWide Web is the universe of network-accessible information, an
embodiment of human knowledge."
Electronicmail(Email)
E-mail (electronic mail) is the exchange of computer-storedmessages by
telecommunication.
E-mail is one of the protocols includedwith the TransportControl
Protocol/InternetProtocol (TCP/IP) suite of protocols.

8.  Whatis Data Management?
Data managementrefers to an organization's managementof information
and data for secure and structured access and storage.
Data managementtasks include the creation of data governance policies,
analysis and architecture; database managementsystem (DMS) integration;
data security and data source identification, segregation and storage.
 DatabaseManagementSystem
A database management(DBMS) system is a software tool that enables
many users to add, view and work with the data in a database.
We should brush up on the concepts below to start our data management
journey.
 Data access refers to your ability to get to and retrieve information
wherever it is stored. Certain technologies can make this step as easy
and efficientas possible so you can spend more time using the data –
not just trying to find it.
 Data quality is the practice of making sure data is accurate and
usable for its intendedpurpose. This starts from the moment data is
accessedand continues through various integration points with other
data – and even includes the point before it is publishedor reported.

9.  Data integration defines the steps for combiningdifferent types of
data. Data integration tools help you design and automate the steps
that do this work.
 Data federationis a special kind of virtual data integration that
allows you to look at combineddata from multiple sources without
the need to move and store the combinedview in a new location.
 Data governance is an ongoing set of rules and decisions for
managingyour organization’s data to ensure that your data strategy
is alignedwith your business strategy.
 Master data management (MDM) defines, unifies and manages all
of the data that is common and essential to all areas of an
organization. This master data is typicallymanagedfrom a single
location or hub.
 Data streaming involves analyzingdata as it moves by applyinglogic
to the data, recognizingpatterns in the data and filteringit for
multiple uses as it flows into your organization.
To create a database, we must first set up its tables and
define the types of fields each table will contain.
