  3. Computer Networks • Computers need to communicate with each other • 2 or more connected devices • Share files & resources • Standards allowed them to “speak the same language”

  4. Network Benefits • Central Storage of files • Share files, resources, printers • Maintain network centrally • Secure • Backup

  5. Network Disadvantages • Unauthorized shared data • Network failure • Easy to spread malicious programs & viruses • Loss of privacy

  6. Networking Components • NIC • Ethernet Cable • Wireless NIC • Router • Cable/DSL/FiOS Modem

  7. Used in business/schools Computers & devices connect to a server Client-Server Network

  8. Peer to Peer Network • Used at home (NO SERVER) • Router allows devices to connect to each other • Also allows shared Internet connection

  9. Sharing Internet at Home • Comcast Cable Modem • Through cable TV wire • High Speed Broadband • Verizon DSL • Over phone line • High Speed Broadband • Limited distance • Verizon FiOS • Over fiber cable line • High Speed Broadband • Limited areas

  10. Identify what you have? • Look at Modem’s WAN or INTERNET port • Comcast • Coax Cable Wire • Verizon DSL • DSL Modem connects to Phone Jack • Filters on phones • Verizon FiOS • Cable Wire • Dial-Up • Computer modem to phone jack

  11. Assignment • What Do You Have at Home? • Identify your Internet connection • Add a diagram to your “My Computer” PPT • Use pictures of your devices • Show wired & wireless connections • Show modems/routers and how they connect • Don’t forget cell phones, TV’s, video games, tablets, thermostats, etc.

  12. Network Categorized- LAN • LAN • Local Area Network • Devices connected in small area • This classroom, this school, your house

  13. Network categoriezed- WAN • WAN • Wide Area Network • Connects LANs • Over a large geographic area

  14. Internet • Originally for government • Largest network • What’s the most commonly used feature on the Internet? • Email • Email is stored on a server • NOT ON PC

  15. Review • What device allows the sharing of Internet access? • Router • What is the purpose of a network? • Sharing files & resources • How many wires are in an Ethernet cable? • 8 • What does LAN stand for? • Local Area Network

  16. Intranet • Looks like Internet • Private • Only works w/in company network • Great security • Handbooks, forms, news, policies

  17. Intranet Screenshot

  18. Extranet • Private • Allows outside organization to access internal info • Extension of intranet • Outside suppliers • Employees • Strict security • Username & password

  19. Extranet Screenshots

  20. Review • A room of 5 connected computers describes a… • LAN • To connect to a network, your PC must have a… • NIC • This type of “Internet” is for internal use only within a business. • Intranet End of Day Two
