Answer 1

Hello
There are two popular Wirless N/W used now a days
1.Blue tooth wireless n/w (PAN) used as personal area network
2.Wi-Fi used as lan (Local area n/w)

Blue tooth n/w is used to connect two pcs or a pc with a bluetooth enabled devices like cell phones and headsets etc.
The range of this is from 10m - 100m and speed is 1Mbps
Cost of a blue tooth dongle is nearly Rs 250/- to 1500/- depends on the manufacture

Wi-Fi is used to get internet access at hotspots ( http://en.wikipedia.org/wiki/Hotspot_(Wi-Fi) ) for example a college will take a internet connection from a ISP and share it through out the college students through wireless routers then the college is a wi-fi hotspot.

For connecting a computer using wireless n/w see this tutorial from Microsoft Website

its nothing but a network without wires to used for connecting between computers or servers...

Wireless networks have significantly impacted the world as far back as World War II. With the use of wireless networks, information could be sent overseas or behind enemy lines easily and quickly and was more reliable. Since then wireless networks have continued to develop and its uses have significantly grown. Cellular phones are part of huge wireless network systems. People use these phones daily to communicate with one another. Sending information over seas is only possible through wireless network systems using satellites and other signals to communicate across the world otherwise getting information Emergency services such as the police department utilize wireless networks to communicate important information quickly. People and businesses use wireless networks to send and share data quickly whether it be in a small office building or across the world. An other important use for wireless networks is as an unexpensive and rapid way to be connected to the Internet in countries and regions where the telecom infrastructure is poor or there is a lack of resources, like most Developing Countries.

Wireless networks allow you to eliminate messy cables. Wireless connections offer more mobility, the downside is there can sometimes be interference that might block the radio signals from passing through. One way to avoid this is by putting the source of your wireless connection in a place that the signal will have as little interference as possible. Sometimes nearby networks are using the same frequencies, this can also cause interference within the network and can reduce its performance.

Compatibility issues also arise when dealing with wireless networks. Different components not made by the same company may not work together, or might require extra work to fix compatibility issues. To avoid this, purchase products made by the same company so that there are fewer compatibility issues.

Wireless networks, in terms of internet connections, are typically slower than those that are directly connected through an Ethernet cable. Though the speed is slower, most things will still move at the same speed except for things like video downloads. Though wireless technology continues to develop, it is now easier to get networks up and running cheaper and faster than ever before.

A wireless network is more vulnerable because anyone can try to break into a network broadcasting a signal. Many networks offer WEP - Wired Equivalent Privacy - security systems which have been found to be vulnerable to intrusion. Though WEP does block some intruders, the security problems have caused some businesses to stick with wired networks until security can be improved. Another type of security for wireless networks is WPA - Wi-Fi Protected Access. WPA provides more security to wireless networks than a WEP security set up. The use of firewalls will help with security breaches which can help to fix security problems in some wireless networks that are more vulnerable.

Wireless Network or WLAN, is a technology were instead of cable you use radio frequency to transmit information.
You need wireless network cards, if distance is long you need wireless access points or bosters to make the signals strong.
The advantage is that, there are less cables and also that now a days laptops/notbooks have built in WLAN so you do not have to connect and disconnect cable form them.
the same way u connect any network just assign TCP/IP address and there is a software provide with it to be configured with a Ip address also.
Once u tried it u will feel comfrotable it is not that difficult

Answer 4

A wireless network is great for laptops, so you can use your laptop anywhere in your home and connect to the internet through a broadband router. advantage (no cables) hope this helps.

Answer 5

nicely, you fairly could have a on the spot community without broadband connection. this would enable all computers linked to the on the spot community to communicate with one yet another, yet there will be no internet connectivity to share. many times in spite of the undeniable fact that, a on the spot connection is used on the side of a broadband connection. (of path, you have a style of machines with a dial-up connection, yet do no longer attempt sharing that!)

Answer 6

It is like a cordless phone in your home. You don't have to stick to one point. You just need to buy a wireless router and an adapter for computers you now have.

Answer 7

network without wires
