1. Module 4: Fundamentals of Communication Technologies

2. Network Content Types Packet Delivery Methods

3. Lesson 1: Network Content Types What Is Static Content? What Is Dynamic Content? What Is Streaming Content? Demonstration: Viewing Network Content Types

4. What Is Static Content? Examples of static content are: Basic HTML Web pages Word documents PowerPoint slides Static content is the same for all users that view it

5. What Is Dynamic Content? Dynamic content is Generated by the server at the time it is accessed Can vary for each user ASP and ASP.NET Examples: A Web page that that includes a users name in the upper right corner when logged on A Web page that displays the IP address of a user accessing content A Web page that changes content to match the demographics of a user

6. What Is Streaming Content? Streaming content is Delivered at the speed required for playback Provided by Windows Media Services Examples: Online radio station Viewing online videos

7. Demonstration: Viewing Network Content Types In this demonstration, you will see static and dynamic content

8. Lesson 2: Packet Delivery Methods What Is Unicast Packet Delivery? What Is Broadcast Packet Delivery? Scenarios for Broadcast Packet Delivery What Is Multicast Packet Delivery? Scenarios for Multicast Packet delivery Demonstration: Viewing Packet Delivery Methods

9. What Is Unicast Packet Delivery? Unicast packet delivery is used for: DNS lookups Accessing Web sites File transfers Logons Unicast packet delivery is performed directly between two hosts

10. What Is Broadcast Packet Delivery? The last IPv4 address on a network is the broadcast address Broadcasts are not forwarded by routers In special cases, a broadcast can be sent to a remote network Examples: 255.255.255.255 – broadcast on local network 192.168.1.255 – broadcast on 192.168.1.0 network Broadcast packet delivery is from one host to all hosts on a network

11. Scenarios for Broadcast Packet Delivery Some common scenarios for broadcast packet delivery are: DHCP NetBIOS name resolution ARP

12. What Is Multicast Packet Delivery? All computers in a multicast group use the same multicast IPv4 address IPv4 address range: 224.0.0.0- 239.255.255.255 Hosts can have multiple multicast addresses Multicast addresses are selected by the applications using the address Routers can be configured to route multicast packets Multicast packet delivery is from one host to a group of hosts

13. Scenarios for Multicast Packet delivery Common scenarios for multicast packet delivery are: Windows Deployment Services Windows Media Services

14. Demonstration: Viewing Packet Delivery Methods In this demonstration, you will see how packet delivery methods vary when viewed by using Network Monitor
