REVIEWING THE BASICS

1)Name three types of Ethernet. What transmission speed does each support?

2. What is the maximum length of a cable on a 100BaseT network?

3. What does the 100 in the name 100BaseT indicate?

4. What is broadcasting? Name a network connection device that uses it and one that does not.
5. What IEEE standards describe Ethernet? What IEEE standards describe wireless LAN?

6. What are three ways a wireless network can be secured?

7. What connecting device do you use for a small LAN? Two or more connected networks?

8. Describe the structure of an IP address. How is it different from a MAC address?

9. How many potential IP addresses are there?

10. How many networks and addresses are available for Class A IP addresses? Class B?

Class C?

11. Why are Class D and E addresses not available to individuals and companies?

12. Which octets are used for the network address and for host addresses in Class A? Class B? Class C?
13. In what class is the IP address 185.75.255.10?

14. In what class is the IP address 193.200.30.5?

15. Describe the difference between public and private IP addresses. If a network is using private IP addresses, how can the computers on that network access the Internet?
16. Why is it unlikely that you will find the IP address 192.168.250.10 on the Internet?

17. Which Windows operating system does not automatically include the NetBEUI protocol?

18. What are the two ways an IP address can be assigned to a PC? What is one advantage of each?
19. For what are the Ping, Ipconfig, and Winipcfg utilities used?

20. Of IPX/SPX, TCP/IP, and NetBEUI, which is routable and which is not?

21. Place the following bandwidth technologies in the order of their highest speed, from slowest to fastest: SDSL, ISDN, regular telephone lines, cable modem, Gigabit Ethernet, ATM.

22. When using DSL to connect to the Internet, the data transmission shares the cabling with what other technology?

23. Give two examples of broadband technology.

24. Which is more expensive, UTP CAT5e cabling or STP CAT5e cabling?

25. What is the most common type connector used with coaxial cable on a ThinNet Ethernet network?

26. If you wanted to upgrade your 100BaseT Ethernet network so that it will run about 10 times the current speed, what technology would you use?

27. A network uses a subnet mask of 255.255.255.0 and has a computer on the network with the IP address of 120.12.12.3. Will the IP address 120.12.10.3 be on the network? Explain your answer.

28. What networking protocol was first used by Novell NetWare and is not supported on the Internet?

29. If you were going to connect two PCs together in a simple network using the network ports on each PC, what type cable would you use?

30. When using a cable modem to connect to the Internet, the data transmission shares the cabling with what other technology?

THINKING CRITICALLY

1. 1. You have just installed a network adapter and have booted up the system, installing the drivers. You open My Network Places on a remote computer and don’t see the computer on which you just installed the NIC. What is the first thing you check?
      1. Is File and Printer Sharing installed?

1. 1. 2. Is the NetBEUI protocol installed?

1. 1. 3. Are the lights on the adapter functioning correctly?

1. 1. 4. Has the computer been assigned a computer name?

1. 2. You work in the Accounting Department and have been using a network drive to post Excel spreadsheets to your workgroup as you complete them. When you attempt to save a spreadsheet to the drive, you see the error message, “You do not have access to the folder ‘J:\’. See your administrator for access to this folder.” What should you do first? Second?
      1. Ask your network administrator to give you permission to access the folder.

1. 1. 2. Check My Network Places to verify that you can connect to the network.

1. 1. 3. Save the spreadsheet to your hard drive.

1. 1. 4. Using Windows Explorer, remap the network drive.

1. 1. 5. Reboot your PC.

1. 3. Your job is to support the desktop computers in a small company of 32 employees. A consulting firm is setting up a private Web server to be used internally by company employees. The static IP address of the server is 192.168.45.200. Employees will open their Web browser and enter personnel.mycompany.com in the URL address box to browse this Web site. What steps do you take so that each computer in the company can browse the site using this URL?

1. 4. Linda has been assigned the job of connecting five computers to a network. The room holding the five computers has three network ports that connect to a switch in an electrical closet down the hallway. Linda decides to install a second switch in the room. The new switch has four network ports. She uses a crossover cable to connect one of the four ports on the switch to a wall jack. Now she has five ports available (two wall jacks and three switch ports). While installing and configuring the NICs in the five computers, she discovers that the PCs connected to the two wall jacks work fine, but the three connected to the switch refuse to communicate with the network. What could be wrong and what should she try next?
