The maximum segment length of a 10Base5 Thicknet is 500 meters.
Maximum number of segments:5 Maximum segments with nodes: 3 Maximum
number of repeaters: 4 Maximum overall length with repeaters: 2.5 kilometers
Maximum AUI drop cable length: 50 meters
Thicknet uses 15 pin AUI connector.
22. 10BaseT Ethernet specifies UTP cabling. UTP cabling uses RJ-45
connectors to connect the cable to the NIC (Network Interface Card).
- 10BaseT is an example of STAR topology 2.
- 10Base2 is an example of BUS topology 3.
- FDDI is an example of fiber optic network based on ring topology.
10Base2 cable uses 50 Ohm, RG-58 cable also called Thinnet.
uses 50 Ohm, RG-8, or RG-11 cable also called Thicknet.
24. One of the disadvantages of 10Base2 Ethernet is that, any cable break
at any point on the network may cause breakdown of the entire network.
25. Some of the important TCP/IP related diagnostic commands that need to
be practiced for Network+ exam are: Command Description PING Used to ping
the remote system (or the local host) to see that the TCP/IP connection is
through. NBTSTAT This utility displays current NetBIOS over TCP/IP
connections, and display NetBIOS name cache. NETSTAT Displays protocol
statistics and current TCP/IP connections since the server was last booted.
TRACERT Used to determine which route a packet takes to reach its
destination from source. IPCONFIG Used to display Windows IP configuration
information. NSLOOKUP This utility enables users to interact with a DNS
server and display resource records. ROUTE Used to display and edit static
26. WAN (Wide Area Network) devices extend the reach of LAN (Local Area
Network) devices. WANT typically span over a wide area, such over multiple
cities / countries. WANS are connected over serial lines that operate at
lower speeds than LANs. Some of the WAN devices are: 1. Routers: Routers are
responsible for routing the packets in an internetwork. 2. Modems: Modems
connect to public telephone circuits through dial-up. 3. CSU/DSU: Stands for
Channel Service Unit / Data Service Unit. CSU/DSUs are used for connecting
to Central Office of a Telephone switching company and provides serial WAN
connections. 4.Communication Servers: These are used for dial in/out to
remote users. Provides RAS Remote Access Server) functionality. 5.
Multiplexers (mux): Multiplexers combine two or more signals before
transmitting on a single channel. Multiplexing can be done by sharing
"time" or "frequency".
27. Routing protocols job is to maintain routing tables and route packets
appropriately. Examples of routing protocols are RIP, IGRP,EIGRP,OSPF.
Routers can support multiple independent routing protocols and can update
and maintain routing tables for each protocol independently. Routed
protocols are used to transport user traffic from source node to destination
node. Examples of routed protocols are IP, IPX, AppleTalk.
28. Both PPP and SLIP can be used for dial up connections. However, SLIP
can't be used where the IP address need to be assigned dynamically. The
advantage of PPP is multi protocol support, that it can support TCP/IP, IPX,
AppleTalk etc. SLIP can support only TCP/IP and IP addresses need to be
29. Default subnet mask for Class A network: 255.0.0.0 Default subnet
mask for Class B network: 255.255.0.0 Default subnet mask for Class C
30. The transmission speed of a T1 circuit (Used mainly in North America)
is 1.544Mbps The transmission speed of an E1 circuit (Used mainly in Europe)
is 2.048Mbps. The transmission speed of a T3 circuit (Used mainly in North
America) is 44.736 mbps
