Cover: Both the front and back covers of the first printing have the phrase "Hundreds of practice questions" near the Practice Exam Software graphic. The practice software contains 120 questions; the video demo contains an extra 42 questions.
p. 6. Current (04-01-02) pricing for for the Net+ test is $199 for non-CompTIA members.
p. 21, question 2. Answer A should be mouse.
p. 22, change the explanation for question 2 to the following:
A. A mouse is not a resource that would be typically shared on a network.
p. 34, second to the last paragraph should read "...it puts the receiving and sending systems' MAC addresses on the frame..."
p. 38, third full paragraph, DHCP stands for Dynamic Host Configuration Protocol, not Control.
p. 58, second to the last sentence of the first paragraph under Layer 4, should read as follows (change in bold):
The protocols that typically handle this job include NetBEUI, SPX, and, of course, TCP.
p. 63, answer for question number 3 should read as follows:
A. All versions of Windows 9x can use the WINIPCFG command to find the MAC address. The last 9x versions (SE and ME) could also use IPCONFIG.
p. 72, third sentence. "...the only difference is that instead of a logical bus, it uses a logical star" should read "...the only difference is that instead of a logical bus, it uses a logical ring."
p. 76, first section should be RG-62 rather than RG-6. The paragraph below should read as follows:
RG-62 cable (rated at 75 Ohms) is virtually never installed in networks these days, but you should know about it nonetheless. It was used in ARCnet networks, likewise virtually extinct.
p. 76, second section, third sentence, should read as follows:
At first glance, RG-58 looks like RG-6 (used for cable television – see Figure 4-11) or RG-59 (also for cable television), but it's 50-Ohm rating makes it very different on the inside (see Figure 4-12).
p. 85, explanation for question 7 should read as follows: "RJ-45 is a type of connector for unshielded twisted pair cabling.”
p. 119, second sentence of the first full paragraph has a reference to Figure 5-43. It should say Figure 5-41. Also, Figure 5-41 has a typo. The computers in Collision Domain 2 should be labeled E, F, G, and H, rather than A-D. Click the thumbnail below for a generic rendering of the picture.
p. 138, fourth item in bulleted list under 10BaseT should read "No more than 1024 nodes per collision domain" rather than per hub.
p. 140, 10BaseFL summary. The distance between a hub and node is 2000 meters, not 100 meters.
p. 146. The first complete sentence, which begins, "100BaseFX is an improvement..." should read as follows:
100BaseFX supports a maximum cable length of 400 meters.
p. 162, Figure 7-5. Computer D should be 4 Mbps rather than 4/16 Mbps to demonstrate that one slow node slows the entire Token Ring network down.
p. 176, question and answer 10. 802.11b should read 802.11.
p. 195, third to the last line should read as follows: "...the female DB-15 connector used on 10Base5 Ethernet networks...
p. 196, third to the last line should refer to 10Base5 rather than 10Base2.
p. 200, the caption for Figure 8-27 should read "ST (l.) and SC (r.) connectors."
p. 203, question 6. Add this sentence to the end of the proposed solution:
Replace all existing hubs with 100BaseTX hubs.
p. 204, Question 10 should read as follows:
Which of the following is not a connector used for networking?
A. Centronics
B. RJ-45
C. BNC
D. DB-15
p. 204, Answer 3 should read as follows:
Driver Update Utilities are not commonly found on the floppy disks that come with NICs.
p. 205, Answer 10 should read as follows:
A. You'll find Centronics connectors on older printers and some SCSI devices. They were not commonly used in networking.
p. 211, fourth line from the bottom should read "... 10Base5 NIC to convert the 15-pin DIX (AUI) connector..."
p. 238. Replace the explanation for question 3 with:
CAT levels do not define the number of pairs, only the speed that the cables can handle.
p. 250, first sentence of the second paragraph. NEC stands for the National Electrical Code, specifications for electrical wiring and such put out by the National Fire Protection Association in the USA.
p. 286, last sentence. SAP stands for Service Advertising Protocol.
p. 287, Figure 11-18. The Transport layer in the figure should refer to SPX, not IPX.
p. 290, second paragraph. SAP stands for Service Advertising Protocol.
p. 293, last sentence of the "Dealing with Protocols" section. Change "thorough" to "through."
p. 302, first binary listing should read like this (changed digit in bold):
11000101101010010101111001010010
p. 323, figure 12-21. Class B hosts per Network should read 65534, not 65546.
p. 324, Figure 12-22 lost something in the translation. Here's what it should be:
p. 325, Figure 12-23. The numbers you can't use are the first (129.30.0.0) and last (129.30.240.0), rather than second to the last. Also, the larger network ID and subnet mask at the top of the figure should have the vertical bar moved to the right by one zero, to reflect moving four places.
p. 326, the three bullet points at the bottom should read like this:
• 10.0.0.0 through 10.255.255.255 (One class A license)
• 172.16.0.0 through 172.31.255.255 (16 class B licenses)
• 192.168.0.0 through 192.168.255.255 (256 class C licenses)
p. 340, table 12-2. The caption should read "IPv6 addresses and their function"
p. 340, table 12-2. The Unicast address for IPv6 in the first column should be as follows:
1080:0:0:0:8:800:200C:417A
p. 368, last sentence of second full paragraph should read as follows (changes in bold):
Windows 2000 installs only TCP/IP by default, although through extra configuration it can support NetBEUI, IPX/SPX, and AppleTalk.
p. 378, first line, change "alternte-clicks" to "alternate-clicks."
p. 378, Question 9, last line should read as follows (change in bold):
Which of these protocols does Windows 2000 install by default?
p. 380, Answer 9, should read as follows:
C. Windows 2000 installs TCP/IP by default. NetBEUI and IPX/SPX come with Windows 2000, but you must install them manually.
p. 422, question #6 should drop the word "client" as follows:
Which of the following systems can act as a printer server on a Novell NetWare network? (Choose all that apply)
p. 430, figure 15-3. The root should display a dot between the quotation marks, like this: "."
p. 436, Figure 15-9. The top-most server should be called the root DNS server, rather than Client's DNS server.
p. 437, first sentence. Change DNA resolver cache to DNS resolver cache.
p. 449, second sentence of second paragraph. Change "...and corresponding TCP/IP names of the host systems..." to "...and corresponding IP addresses of the host systems..."

p. 553, Answer 10. 2TP should read L2TP.
p. 558, first full paragraph. Both mentions of LocalTalk should be AppleTalk. AppleTalk is the protocol used by older Macintosh computers. LocalTalk was Apple's early networking technology, not a protocol.
p. 607, second paragraph. Delete the last sentence, "In this case, a file called SHELL32.DLL..." It refers to an earlier version of figure 20-26.
p. 615, about mid-way through the second full paragraph, change in bold:
"At that point, you might check his TCP/IP configuration by using the IPCONFIG utility."
p. 635, fifth sentence in the second paragraph under the section "Using the Four-Layer Model." The sentence should read as follows, with change in bold:
"I then fired up IPCONFIG and released and renewed the IP address..."
p. 636, first full paragraph, third sentence. Change "WINIPCFG" to "IPCONFIG."
p. 643, the first entry in the Glossary is the 5-4-3 Rule. The second sentence should read (changes in bold);
"In a collision domain, no two nodes may be separated by more than 5 segments, 4 repeaters, and 3 populated segments."

p. 703. SAP stands for Service Advertising Protocol.
