1. Instructor & Todd Lammle Sybex CCNA 640-802 Chapter 1: Internetworking

3. Internetworking Basics How would you say the PC named Bob communicates with the PC named Sally?

4. Internetworking Basics Switches can replace the hub, breaking up collision domains. Keep in mind that the hub used in the figure just extended the one collision domain from the switch port.

6. Internetworking Basics Routers create an internetwork.

8. Internetworking Basics Internetworking devices

9. Internetworking Basics Switched networks creating an internetwork

12. The OSI Model The upper layers

24. Ethernet Collision Detection CSMA/CD

26. Ethernet Addressing The MAC, or hardware, address is a 48-bit (6-byte) address written in a hexadecimal format.

27. Ethernet at the Physical Layer The IEEE 802.3 and original Ethernet Physical layer specifications.

31. Rolled Cable Although rolled cable isn’t used to connect any Ethernet connections together, you can use a rolled Ethernet cable to connect a host to a router console serial communication (com) port.

32. Using Hyper Terminal Notice the settings for Hyper Terminal

33. What type of cable is used?

34. What type of cable is used for each connection?

36. PDU

37. Port Numbers The Transport layer uses port numbers to define both the virtual circuit and the upper-layer process.

39. Review Question How many broadcast domains are shown? Hub Hub

40. Review Question Hub Hub Hub Hub Hub Hub Switch Switch How many collision domains are shown?

41. Which of the hosts can transmit simultaneously without causing collisions? Hub Switch How many collision and broadcast domains are show? A F E D B C
