I have a new laptop, I know you can use a wireless card for internet connection, what is USB plug?

Question

I have used the wireless bridge supplied by motels when traveling, I know about the wireless card from wireless carriers, but what that USB plug thing I see people using? They just insert it on the side of the laptop and have internet connection. Can some computer genius explain ?

Answer 1

USB stands for Universal Serial Bus. A USB port is used for many different things. Probably what you'd see people using them for most often these days are jump drives. They're little keychain flash memory drives which you can save your stuff on and transfer it to other computers. It's like a miniature hard drive with no moving parts. It's a very handy device! There are also Wireless Internet cards that work on USB, Bluetooth, Wireless Mice which are popular with laptops, even a light that plugs into your USB and lights up your keyboard so you can type at night! Most printers these days use a USB connection as well. I'm sure you'll find plenty of uses for it.

Answer 2

The device your probably talking about is Bluetooth, although there are other devices that do the same thing. This allows you to use your cell phone as the computers MoDem(although at some slower speeds). The Universal Serial Bus allows a standard connection method for installing a device to your computer and allowing it function as if it was integrated into the PC. It is a configuration created to be Standard and Uniform on all PC's thereby providing a vehicle which allows many different hardware manufacturer to create devices which will work on any PC or laptop.you can buy enclosures which allow you to create additional hardrives and use them on your PC for back up, additional storage capacity etc. Devices which are USB cover the entire range of products sold for the computer everything from memory (jump drive) to devices which convert USB into another method of connectivity. In the past you had connection points which were designed for one type of device like PS connectors, USB allows that same access point to be used for many devices. The Bus is similar to a bus you would find in an electrical breaker box, each breaker controlling one device but obtaining electrical power from a common copper conductor. USB is one the better configuration changes that PC manufacturers have devised recently, another is the Type II and express PC slots for laptops. Uniformity drives innovation, allowing PC's to do more and manufacturers a vehicle to overcome proprietary configurations. Remember Beta vs. VHS in recorders, Beta went the way of the dinosaur not because VHS was better, but because VHS manufacturers sold more units thereby creating a standard. USB prevents that sort of darwinian selection process in peripheral design and allows the better technology to rise to the top overcoming other factors such as marketing strategy.

Answer 3

I've never had any problems with the USB wireless connection on my PC (Belkin) Though, I have to agree that the PCMCIA card would be tidier

Answer 4

The plug is used when people want to use internet at public places. The connects to a laptop and to the place's outlet. This way, you share the internet connection. Some areas charge you money for every minute, and they proved a code for you to input that will allow you to use their internet connection.

Answer 5

Answer 6

your wireless care is fine, as for the sub connection that's for the use of a printer, or a cell phone, they use the modem from the cell phone in order to brows the web, if you are at the motel they will have an access code for you to use their Internet connection while you stay.
