1.Given that there are 5 nodes in a LAN and a connection between each pair of nodes is $10. Based solely on the price of connections, how much would a full mesh topology cost?
2.Given that there are 5 nodes in a LAN and a connection between each pair of nodes is $10, how much would a ring topology cost?
3.If the 8-port 10BaseT hub is replaced by an 8-port 10BaseT switch, how many pairs of PCs, in the 6-PCs LAN, can be communicating with each other through that 8-port 10BaseT switch at a time, under the most ideal condition?
4.How many pairs of PCs, in the 6-PCs LAN, can be communicating with each other through that 8-port 10BaseT hub at any one time?
5.State a topology that would be cheaper than the ring topology. How much would this topology cost using the same $10 per connection for each pair of nodes, based on 5 nodes in the LAN?

A logical topology is a concept in networking that defines the architecture of the communication mechanism for all nodes in a network. Using network equipment such as routers and switches, the logical topology of a network can be dynamically maintained and reconfigured.
Switch learns network MAC addresses
And controls the network packets to reduce broadcast packet traffic on your network !

Hi,You are right mvincentc , for more IP related informations you can use this http://www.whoisxy.com/ site for best result.here only i got my exact address and other details,It is totally free site .visit here for more details.
1. Go to desktop of 1st computer 2. Right click on ‘My Computer’ icon. 3. Click on Properties 4. A new window is opened 5. Click on ‘Computer Name’ Tab
LAN Topology 6. Click on ‘Change…’ button. 7. A new window is opened. 8. Give the Computer Name e.g. Ahmad’s Computer. The computer name should be unique for each computer. 9. Now choose the ‘Workgroup:’ radio button and enter the name of your network e.g. Office Network. 10. Repeat the steps ‘b’ through ‘I’ for each computer. 11. Restart each computer and your network is ready to work.
This model has three ways of connecting:
- wireless lan (from a wireless router or Wi-fi)
- wired ethernet (connects to dsl or cable modem via network cable)
-wired 56K modem (connects from phone jack to wall jack-slowest)
Compliancy : Wi-Fi® <---------- Network Support : 802.11b/g integrated Wireless Technology : Wireless LAN
topology : Ethernet LAN <-------- speed : 10/100 Base-TX topology : international V.90 modem (V.92 ready) <------ speed : 56 Kbps data and V.92 data fax
Regardless of how you connect, you must first have a Internet Service Provider.
If you don't already have one, look in your LOCAL phone book under "internet", call a few and find out what they have to offer. If your just surfing the net, reading e-mails, etc. a 1.2m connection will suffice.
If your gaming, hosting a web site , or performing any other bandwidth consuming activity you might consider a faster connection.
The price per month is also a factor.
i usually take a few notes on price, availability in my area, speeds offered, features offered and wether they give me a free modem with thier service.
dont do 56K dial-up, you will beat yourself silly while you wait for the webpages to load.
