2. Home Networks What is a home network What good is having one - neat things you can do with one General network info How to set one up Q & A

3. What is a home network?

4. According to Wikipedia: a network is “a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information”.

5. What is a home network? According to Wikipedia: a network is “a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information”. Plain English: computers, etc. connected together so you can share stuff between them

6. What is a home network? According to Wikipedia: a network is “a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information”. Plain English: computers, etc. connected together so you can share stuff between them If you use the internet, you use a network

7. What good is a home network?

8. All your computers can share: A high speed internet connection

9. What good is a home network? All your computers can share: A high speed internet connection One (or more) printers

10. What good is a home network? All your computers can share: A high speed internet connection One (or more) printers External disk drive(s) for backup

11. What good is a home network? All your computers can share: A high speed internet connection One (or more) printers External disk drive(s) for backup Scanner(s)

12. What good is a home network? All your computers can share: A high speed internet connection One (or more) printers External disk drive(s) for backup Scanner(s) Files and folders on each computer

13. What good is a home network? All your computers can share: A high speed internet connection One (or more) printers External disk drive(s) for backup Scanner(s) Files and folders on each computer Other network devices (cameras, etc)

14. General network info

15. Each device on a network needs a unique address (IP address)

16. Like houses on a street: State, Town/City, Street name, Individual house numbers

17. Each device on a network needs a unique address (IP address) Like houses on a street: State, Town/City, Street name, Individual house numbers Network addresses are 4 numbers separated by periods.

18. Each device on a network needs a unique address (IP address) Like houses on a street: State, Town/City, Street name, Individual house numbers Network addresses are 4 numbers separated by periods. All devices on your network must have the first 3 numbers the same, and the last number different

19. Each device on a network needs a unique address (IP address) Like houses on a street: State, Town/City, Street name, Individual house numbers Network addresses are 4 numbers separated by periods. All devices on your network must have the first 3 numbers the same, and the last number different Most home networks are 192.168.1.x or 192.168.0.x

20. Types of network addresses

21. 2 types – dynamic and static

22. Types of network addresses 2 types – dynamic and static Static: Address stays the same - may need this for some devices (printers, etc)

23. Types of network addresses 2 types – dynamic and static Static: Address stays the same - may need this for some devices (printers, etc) A little harder to set up

24. Types of network addresses 2 types – dynamic and static Static: Address stays the same - may need this for some devices (printers, etc) A little harder to set up Think of it like a house

25. Types of network addresses 2 types – dynamic and static Static: Address stays the same - may need this for some devices (printers, etc) A little harder to set up Think of it like a house Dynamic: Easiest to set up - a piece of equipment called a “router” takes care of addresses (this is called DHCP).

26. Types of network addresses 2 types – dynamic and static Static: Address stays the same - may need this for some devices (printers, etc) A little harder to set up Think of it like a house Dynamic: Easiest to set up - a piece of equipment called a “router” takes care of addresses (this is called DHCP). Address could change

27. Types of network addresses 2 types – dynamic and static Static: Address stays the same - may need this for some devices (printers, etc) A little harder to set up Think of it like a house Dynamic: Easiest to set up - a piece of equipment called a “router” takes care of addresses (this is called DHCP). Address could change Like renting a space at a campground for a camper

28. Equipment you need

29. Router This handles the addressing, etc.

30. Equipment you need Router This handles the addressing, etc. Network connection for your computer (wired or wireless – more info later)

31. Equipment you need Router This handles the addressing, etc. Network connection for your computer (wired or wireless – more info later) Network connection for anything else (printer, scanner, etc.)

32. Equipment you need Router This handles the addressing, etc. Network connection for your computer (wired or wireless – more info later) Network connection for anything else (printer, scanner, etc.) For internet: modem and high speed service. Router may be part of modem.

33. Block diagram of a network Modem (for internet) Router Computer PrinterOther stuff This can be a wired or wireless connection All data connections are bi-directional (data goes both ways)

34. Wired connection

35. Most secure

36. Wired connection Most secure Fairly easy – just run a network cable to each device

37. Wired connection Most secure Fairly easy – just run a network cable to each device Generally faster than wireless (100 Mb/S)

38. Wired connection Most secure Fairly easy – just run a network cable to each device Generally faster than wireless (100 Mb/S) Difficult to have devices in different rooms (must run network cable through walls, etc)

39. Wireless connection (WiFi)

40. No wires needed – can use it in different rooms

41. Wireless connection (WiFi) No wires needed – can use it in different rooms More difficult to set up – highly recommended to use some type of password protection (more on this later)

42. Wireless connection (WiFi) No wires needed – can use it in different rooms More difficult to set up – highly recommended to use some type of password protection (more on this later) Generally slower than wired

43. Wireless connection (WiFi) No wires needed – can use it in different rooms More difficult to set up – highly recommended to use some type of password protection (more on this later) Generally slower than wired Can have interference problems

44. Wireless connection types/speeds 3 different commonly used types/speeds: B, G, N

45. Wireless connection types/speeds 3 different commonly used types/speeds: B, G, N B – earliest, slowest (11 MB/s) G – newer, faster (54 Mb/S max, mid 20s typical), reasonably priced N – newest, fastest (150 max), most expensive

46. Wireless connection types/speeds 3 different commonly used types/speeds: B, G, N B – earliest, slowest (11 MB/s) G – newer, faster (54 Mb/S max, mid 20s typical), reasonably priced N – newest, fastest (150 max), most expensive Later versions of routers are compatible with earlier devices, later versions of devices may not be compatible with earlier routers.

47. Wireless connection password protection 3 different types WEP – not very secure WPA1 – more secure WPA2 – most secure – use this

48. Sharing a printer

49. Use a device called a “print server”

50. Sharing a printer Use a device called a “print server” Use manufacturer’s instructions and/or installation disk

51. Sharing a printer Use a device called a “print server” Use manufacturer’s instructions and/or installation disk Use a static IP address

52. Sharing a printer Use a device called a “print server” Use manufacturer’s instructions and/or installation disk Use a static IP address Set up each computer to use the printer

53. Set up a network Q & A
