  11. 11. Hope you drank your coffee.... Time for Networking 101
  12. 12. Networking 101 <ul><li>What is a network? </li></ul><ul><ul><li>A network is a group of interconnected computers. </li></ul></ul><ul><li>How are they connected? </li></ul><ul><ul><li>Wired </li></ul></ul><ul><ul><li>Wireless </li></ul></ul><ul><li>Wired Network </li></ul><ul><ul><li>Each computer has an Ethernet port </li></ul></ul><ul><ul><li>Each computer is then connected via an Ethernet cable plugged into the Ethernet port to a central point called a switch. </li></ul></ul><ul><ul><li>The switch takes Ethernet inputs from multiple computers and “switches” data between the different computers. </li></ul></ul>
  13. 13. Networking 101 <ul><li>Think of a computer network in terms of the US Postal Service. </li></ul><ul><ul><li>You are the computer. </li></ul></ul><ul><ul><li>Your mailbox is your computer's Ethernet port. </li></ul></ul><ul><ul><li>The mailman is the network cable. </li></ul></ul><ul><ul><li>The Post Office is the network switch. </li></ul></ul>

  16. 16. Networking 101 <ul><li>Question: </li></ul><ul><ul><li>What information would I need to know in order to send a file (letter) from Computer A to Computer B? </li></ul></ul>Computer A Computer B Switch File File You would need to know Computer B's address!
  17. 17. Networking 101 <ul><li>Ok, how does a computer get an address? </li></ul><ul><ul><li>User assigned – Static </li></ul></ul><ul><ul><li>Server assigned – Dynamic </li></ul></ul><ul><li>What's the difference? </li></ul><ul><ul><li>Static addresses are assigned during the installation by an administrator, and usually don't change. </li></ul></ul><ul><ul><ul><li>If the address needs to change, it must be changed manually </li></ul></ul></ul><ul><ul><li>Dynamic addresses are assigned to a computer when it boots up. The address may or may not be different each time the computer is restarted. The computer will contact a DHCP server and ask for an address. </li></ul></ul><ul><li>Is one address assignment better than another? </li></ul><ul><ul><li>From an administration standpoint, dynamic addressing is easier to manage. </li></ul></ul>
  18. 18. Networking 101 <ul><li>So, my computer has an address now, what does it look like? </li></ul><ul><ul><li>The computer's address is called its IP address. </li></ul></ul><ul><ul><ul><li>IP stands for Internet Protocol </li></ul></ul></ul><ul><ul><li>It is composed of 4 sections of numbers separated by a period. </li></ul></ul><ul><ul><ul><li>A.B.C.D </li></ul></ul></ul><ul><ul><ul><li>For example: </li></ul></ul></ul><ul><ul><li>Generally speaking, for basic installations, the first 3 sections of the IP address (A.B.C.) are never going to change per computer. </li></ul></ul><ul><ul><ul><li>This is referred to at the network portion of the address. You can equate this to be the City, State, Zip portion of the letter. </li></ul></ul></ul><ul><ul><li>The last section of the address (D) is going to be different for every computer on the network. </li></ul></ul><ul><ul><ul><li>This is referred to as the host portion of the address. You can equate this to be the Street portion of the letter. </li></ul></ul></ul>
  19. 19. Networking 101 <ul><li>So, are there any limits to what numbers I can plug in? </li></ul><ul><ul><li>Yes – the only valid values are from 0-223 for the first grouping (A). The second, third and Fourth groupings (B.C.D) have valid values between 0-254. </li></ul></ul><ul><ul><li>IP addresses fall into one of two categories, public and private. </li></ul></ul><ul><ul><li>Public addresses are routable over the Internet. </li></ul></ul><ul><ul><ul><li>The IP address assigned to your cable modem from your ISP is a routable public IP address. </li></ul></ul></ul><ul><ul><li>Private addresses are not routable over the Internet and are used inside a business. </li></ul></ul><ul><ul><ul><li>The IP address your cable modem assigns your computer is a private address. </li></ul></ul></ul>A.B.C.D
  20. 20. Networking 101 <ul><li>Private IP addresses </li></ul><ul><ul><li>While you can use any IP address range for addressing your private network, there are three IP address ranges reserved specifically for private networks: </li></ul></ul><ul><ul><ul><li> - </li></ul></ul></ul><ul><ul><ul><li> - </li></ul></ul></ul><ul><ul><ul><li> – </li></ul></ul></ul><ul><ul><li>It is recommended you stick to the 192.168.X.X address space. </li></ul></ul><ul><ul><ul><li>There are a possible 254 different IP addresses you can use in this space. </li></ul></ul></ul>
  21. 21. Networking 101 Computer A Computer B Switch Our small network, with addresses : File File What do I need to know in order to get the file from Computer A to Computer B? Computer B's IP address! Which is...
  22. 22. Networking 101 <ul><li>When entering in address information into a computer, you will need one more piece of information for a simple network install. </li></ul><ul><ul><li>The Subnet Mask </li></ul></ul><ul><ul><ul><li>The subnet mask tells the computer what portion of the IP address contains the network portion of the address. </li></ul></ul></ul><ul><ul><ul><li>For our example and for most of your installations, it will be the first three sections of the IP address. (A.B.C.)‏ </li></ul></ul></ul><ul><ul><ul><li>The subnet mask is broken out into 4 sections, just like the IP address. </li></ul></ul></ul><ul><ul><ul><li>For our example, our subnet mask uses two values 0 and 255. </li></ul></ul></ul><ul><ul><ul><li>The network portions of the address would have values of 255. </li></ul></ul></ul><ul><ul><ul><li>The host portions would have a value of 0 </li></ul></ul></ul>

  24. 24. Networking 101 <ul><li>Now that we've covered the basics of networking a small office, what about connecting it to that Internet thingy? </li></ul><ul><ul><li>Need to introduce a router into the mix </li></ul></ul><ul><ul><li>For security purposes, a firewall is recommended as well </li></ul></ul><ul><li>The router handles sending data outside the local network, say sending an email to your Aunt Edna in California. Also called the default gateway. </li></ul><ul><li>A firewall inspects data coming into your network and blocks malicious attacks and hackers. The firewall can also be a router. </li></ul>

  26. 26. Networking 101 <ul><li>What does this have to do with IP Surveillance? </li></ul><ul><ul><li>Remember, IP stands for Internet Protocol, the same protocol used by your computers to communicate. </li></ul></ul><ul><ul><li>Which means....We will have to assign an IP address to every camera we want to put on the network. </li></ul></ul><ul><ul><li>The management software uses the IP address in the camera to control the camera. </li></ul></ul><ul><ul><li>The cameras use IP addresses to find the management software and the storage device. </li></ul></ul>
