How Laptop WiFi and Home Wireless Systems Work
Laptop WiFi vs Home Wireless SystemThe Laptop WiFi System
WiFi stands for wireless fidelity. Wi-Fi is a brand name developed by the Wi-Fi Alliance of Austin, Texas. It provides standards and a guarantee that there will be technological compatibility among products which use and communicate in a wireless format via the IEEE 802.11 specification. Can any laptop become a WiFi system? Yes, it can; but not so fast. There are some hardware issues that must be addressed first.
For your laptop to become a WiFi laptop, it must recognize the radio waves transmitted by the ,dell inspiron 9200 battery, router. The router sends out the signals that the laptop must pickup. The laptop must have a wireless network card to pick up the signal. This card is sometimes called a NIC card, or a PCMCIA card.
Installing the wireless card for your laptop is easy if you are using Windows. It will ask you to set up a unique id for the laptop. If you have multiple laptops or PCs on your network, each must have their own unique identifier. Every laptop will identify and recognize the other computers on the WiFi network. Then all of the normal operations that transpire on a network will be available to you. It is not very ,hp laptop batteries, difficult and when the configuration is complete you have a wireless Internet laptop.
One of the other ways that you can create the WiFi laptop is to use USB wireless cards. These are now available that will attach to the USB port. These are inexpensive and easy to use on the system.

The Home Wireless System
The Laptop WiFi system, created earlier with the PCMCIA card, can also be applied to PCs to create your Home Wireless Network. So for that step to take place, the next thing that you need is a ,hp pavilion dv7 battery, router that will create an access point. This will issue a wireless signal that has the frequencies for the wireless connection. This router has a hookup to a high speed Internet connection. The connection then goes back to the ISP, which delivers the Internet packets to the home. This is the cable or DSL connection provided by AT&T, or Comcast, or any number of Internet Providers.
In most instances, you can connect multiple PCs or laptops to your home wireless system. All will have access to the local network, i.e. your home network. The one feature that can be a problem is security.
In a home zxcsky555 wireless system, your connection can be open, and not secure. In this case, as you are sending items across the network to print, for example, your tax forms; these tax forms may be compromised by marauders that pick up the signal, and download your information. Then your personal information is in their hands.
To avoid this danger, wireless systems have some security features. One possibility is to encrypt the connection to the laptop or PC and the wireless system with a WEP key. This means that as you send information over the wire, you avoid sending it in clear text, which anyone can pick up and read. Encryption changes the ,hp pavilion dv2000 battery, appearance of the words before they go over the wire and are decrypted at the receiving end.
WEP stands for Wired Equivalent Privacy. A WEP key brings a security feature to WiFi networks. It is a code set, for example1A648C9FE2, that allow a group of PCs and or laptops on a local network to exchange encrypted messages with each other while hiding the contents of the messages from outsiders.
There are other security elements available such as WPA, TKIP, EAP, LEAP, and PEAP. They are variations of WEP, but usually they are more secure.
