What hardware is required to build a wireless network?
Wireless network adapters (also known as wireless NICs or wireless network cards) are required for each device on a wireless network. Some newer laptop computers incorporate wireless adapters as a built-in feature of the system. Separate add-on adapters must be purchased for most computers, however. Popular wireless network adapters for PCs exist in the form of a PCMCIA "credit card." Macintosh computers use the distinctive AirPort card. USB wireless adapters that do not resemble cards also exist. Strictly speaking, no wireless hardware other than adapters is required to build a small wireless LAN (WLAN). However, to increase the performance of a WLAN, accommodate more computers, and increase the network's range, wireless access points and/or wireless routers can be deployed. Wireless routers function comparably to traditional routers for wired networks. One generally deploys wireless routers when building an all-wireless network from the ground up. An alternative to routers, access points allow wireless networks to join an existing wired network. One typically deploys access points when growing a network that already has a wired switch or router installed. In home networking, a single access point (or router) possesses sufficient range to span most homes. Businesses in office buildings often must deploy multiple access points and/or routers. Access points and routers often utilize a wireless antenna that significantly increase the communication range of the wireless radio signal. These antennas are optional and removable on most equipment. It's also possible to mount antennas on wireless clients to increase the range of wireless adapters. This is common practice for wardrivers, but add-on antennas are generally not required in typical home or business networks.
What advantages exist in having a wireless network in your home instead of a wired network?
Mostly it's about not having to have wires to connect everything. This allows you to place pieces of the network anywhere you want. You also don't have to drill holes in the wall and run wires.
Why 802.11use acknowledgements but not in wired Ethernet?
Two scenarios exist where a wireless network might not know if a frame was successfully delivered, that do not exist in a wired network. First, a weak wireless signal could mean that the sender may not be capable of transmitting and listening at the same time, and this makes collision detection impossible. Second, fading or the hidden-terminal problem could mean that interference occurred during the transmission without the sender knowing.
Where can you check if the wireless adapter is enabled?
1) if your wireless adapter is enable. It would be appear on side of right bottom corner. 2) you can see your adapter position(enable disable).open My network place. Here would be all adapter position which are exist in your system
Do wireless GameCube controllers exist?
no they do not make them in america!
Is ipv6 compatible with ipv4?
IPv4 and IPv6 are two different protocols . The two protocols are not compatible with each other. But they can exist in a same network together.No, those are two different protocols. However, they can co-exist in the same network (this is known as "dual stack").No, those are two different protocols.

What is difference between wireless and wired LAN?
The wire, and the security which comes with the wire, or the security requirements that come from the absence of a wire: A wired network is considered a private network, in the sense that the network owner can generally grant or deny physical access to this network. For example, the wired network inside my house is only accessible to those people inside my house. However, a wireless network not only has no wire, it also implements a public or shared media. Subject to the reach of the access points and routers, my wireless LAN may be accessible from outside my house, and the owner of a wireless network has no immediate means to grant or deny controlled access to this network. To solve this problem, wireless networks use sophisticated authentication and encryption methods to ensure that only authorized users can access a given network, and that nobody else can decipher messages sent on that network. An early form of this security protocol is WEP, short for wire-equivalent privacy (although it was later discovered that WEP wasn't very sophisticated to begin with, and is now superseded by more powerful alternatives). The overhead for authentication and encryption does not exist on a wired network, and impairments that impact the operation on a public media (such as radio-frequency interference. While a wired network might come at the cost of wire installation, it is in principal more secure and faster than a wireless network.

What are differences between WAN and VPN?
Wan- is wide area network , vpn - is a virtual private network, vpns exist within lans, lan exist within wans.
What are the benefits and downfalls of wireless networking?
Wireless networking has a few ups and downs. The most notable is that cable does not need to be run in order for the network to exist. Computers are able to connect to the internet and communicate amongst each other without the need of CAT5e or CAT6 (Gigabit) being run to a Router, Network Switch, or Hub. This allows the network to serve a decent area and makes setting up a home network easy. Prior to wireless networking one would have to run cable to the computers in each room to a "gateway". Another positive is that WiFi networking (now-a-days) is quite easy to setup. Any home user is capable of setting up a multiple computer network via WiFi. Now with connection wizards and the such, one is able to configure a wireless network in under 30 minutes. Now for the downfalls to wireless networking. One of the biggest ones is connection security. Broadcasting information wirelessly results in the ability for the information to be intercepted and captured. This is where wireless security steps in. There are numerous types but as a general rule of thumb, No important information such as Social Security numbers, Bank Account or Credit Card information should be transferred over a wireless connection. Even if you use WPA2-AES (one of the strongest forms) confidential, classified, or sensitive information should not be transferred via a wireless connection. A skilled hacker can also hack your wireless network, and use it for their possible misdeeds including downloading pornography, using it to attack another network and even steal your information. Another caveat to the use of wireless networking is range. Most wireless networks have limited range without the use of numerous AP's (access points) or antennas. (this also affects security) The amount of walls and their contents can affect signal reception as well.
