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

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

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.
