Note that the Graded Discussion Board (GDB) of CS610 computer networks will remain open for two days from 12:00 AM July 4, 2012 to July 5, 2012 till 11:59 PM according to Pakistan Standard Time.
The topic of Graded Discussion Board:
"Do you think wireless networks will totally replace the wired or fixed networks in coming future? Prove validity of your opinion."
A concise, coherent and to the point comment is preferred over lengthy comment having irrelevant details. Your comment must not be more than 5-7 lines. Comments, posted on regular Lesson's MDB or sent through email will not be considered in any case. Any request about such an acceptance will not be catered.
Best of Luck
[b]Solution:-
i don't think that wireless network will replace the wired or fixed networks in coming future.
i would agree to the statement to some extend, but not truly. wireless technology is booming everywhere and everything is flooded with wireless technology.
There are two ways to connect a computer to a network: wired or wireless. Sometimes this will determine the kind of router you purchase, but fortunately today most offer both options.
A wired connection requires an Ethernet cable be run between the router and your computer. In a wireless connection, you use hardware in your computer to communicate with the router without that cable.
Both have advantages and disadvantages so to help you pick the right one for you, here are 5 things to consider when deciding on a network connection.
1. Ease of Set-Up
Wired connections are easier to set up. With most modern computers you can simply plug in the cable and get on the Net. Wireless requires configuring the router and at least one extra step on the computer's side: searching for the correct network to connect to. If you live in an apartment building in the city and go to connect to your network, you'll probably see a dozen or more different possibilities.
2. Reliability and Speed
Everybody who has used both wired and cordless home telephones knows how much more likely the cordless varieties are to pick up interference and experience problems of quality. The same can be true for wireless Internet. While hardware has improved over the years, other electrical devices can still potentially interfere with your Internet, in some cases causing disconnections and delays. And like cordless phones, problems increase as you get farther away from the router. There are devices to fix such problems, but they can be costly and may require some trial and error.
3. Speed
Wired is almost always faster than wireless, and never slower. This is due to the reliability issues mentioned above and to the technology itself, which simply hasn't caught up to Ethernet-level quality.
4. Convenience
Clearly wireless is more convenient on a day-to-day basis. Once it's been set up, you can access the Internet from any computer in the vicinity of the router. If you can run Ethernet cables throughout your house you can achieve a similar level of convenience while keeping the reliability and speed, but it's a huge undertaking and may not even be possible if, for example, you rent an apartment.
5. Security
This is arguably the most important of these points and the one too few give much thought.
A wired network is fully contained. In order to connect to it, you must have physical access to the router. On the other hand, a wireless network is not contained. Your neighbors, people on the street, or those in the restaurant next door can all potentially find your network on their computers. There are two reasons this should concern you.
First, you don't want people you don't know using your Internet connection. It'll be slower to you and any questionable actions they take online will be traced back to you, not to them.
Second, it's not difficult for a hacker to intercept data sent through an unsecured network. All of the banking, purchasing, and communication you do online could potentially be maliciously saved to a computer. You can imagine the possibilities for identity theft, credit card fraud, and so on.

Wireless
• Wireless networks operate radio waves and/or microwaves to sustain interaction channels linking computers. Wireless networking is a additional recent substitute to wired networking that relies on copper and/or fiber optic cabling.
• Wireless networking is promptly acquiring popularity for home networking. Wireless technology continues to advance, the price of wireless commodities continues to fall.
• A wireless network offers advantages and disadvantages compared to a wired network.
Advantages:
• Neat and clean, no untidy cables
• Flexibility around the home, can connect to the network around the house within a limited range.
• Setup - Those without a great deal of networking experience can set up a wireless network.
Disadvantages:
• The potential for radio interference due to weather, other wireless devices, or obstructions like walls.
• Cost - The biggest drawback of setting up a wireless home network. It is still fairly expensive to go wireless but costs have been gradually decreasing as new technologies are on the rise.
• Reliability - If one major section breaks down, for example the Router, the whole network will be affected.
Wired
• Wired Local Area Networks make use of Ethernet cables and network adapters. Numerous computers can be wired to one another by using an Ethernet crossover cable. Wired LANs also need vital devices like hubs, switches, or routers to aid further computers.
• For dial-up connections to the Internet, the computer hosting the modem should administer Internet Connection Sharing or similar software to share the connection with every other computers on the network.
• Broadband routers permit easier sharing of cable modem or DSL Internet connections, furthermore they often include built-in firewall.
• Ethernet cables should proceed from each computer to a different computer or to the central device.
• The accurate cabling configuration for a wired LAN differs depending on the merge of devices, the form of Internet connection.
• Following hardware installation, the lasting steps in configuring either wired or wireless LANs do not contrast a great deal. Equally rely on standard Internet Protocol and network operating system configuration options.
Advantages and Disadvantages of Wired Networking
advantages:
• The equipment is inexpensive.
• Many computers have a wired network adapter.
• Wired networks transfer information more swiftly
• Wired networks are generally more secure than wireless networks
disadvantages:
• Running the wires from each room within the home can be a difficult task.
• Network cables can look disorganized.
• Network cables can disconnect or become faulty consequently causing the connection to fail.
• Adding more computers to a wired network may result in unexpected expense if you run out of connections on your network and could slow down the network.
All wired networks differ from each other. The most familiar type of wired network is an Ethernet network.
