What happens when you short a usb port on the front of your computer?
My son stuck a paper clip into the USB port on my computer and it appears to have died. Why?
The port died or the computer died? Both are possible. Well, the USB port is always receiving current of at least 400mW so, metal + current = short. In a best case scenario it would only take the port with it. In a worst case scenario the charge goes back to the motherboard and causes damage there though I can't see it going beyond the USB host controller but if it did... we're talking about a mess. I know of other cases like this where the port went... or where the whole computer went or where all the USB ports broke. This is why you don't leave computers around children, children + computers = bad. And I'll really be in a situation if I ever have kids... I have nothing but computers, computer hardware and other sensitive components around me.
That's just a guess on my part. I've never stuck a paper clip in a USB port but it's not something I would want to try.
The existence of the USB Wireless card owes itself to an ever-growing focus on technology that is conveniently mobile. Phones are smaller, cameras are smaller, computers are smaller... and more and more, you can use them everywhere, with a greater number of features packed into them. People want to be able to do everything they used to do at home, only anywhere. And USB wireless devices enable that to an extent never before seen. USB devices were previously confined to simply being easy file storage devices, much like a portable hard drive. But they've grown sophisticated enough to be handle more complex behavior now, and that includes enabling internet access on the fly.
USB devices have always been very simple forms of technology. Plug them in and go, no matter what computer you're on. So long as the computer has a USB port, you're good to go, and modern computers come with multiple USB ports for just this reason. So, we have a basic form of technological storage that can fit into any computer whenever you like, and it can be carried around in your pocket more easily than even a wallet when not in use. Great. What's the next logical step? Instead of using it for mere file storage, use these USB devices to enable specific activities that a computer otherwise wouldn't have access to. Thus, we have internet on any computer that wouldn't be able to naturally connect to the internet in and of itself. Suddenly, instead of using a COMPUTER for the internet, you keep your internet in your pocket!
Instead of being tied to a particular computer for the internet, you can use the internet with any computer. Instead of needing to buy a permanent fixture for multiple computers, you just plug in the net when you're going to use it. This saves you money and allows you to get online only when it's necessary. When you're not plugged in, your computers aren't online either, which keeps them safe from hacking attempts and misuse of bandwidth. It's secure, it's cheap, but above all else it's something you take with you and use wherever and whenever you feel like using it.
USB devices enabling internet access work on a simple plug and play method of operation. All you have to do is plug them in. They automatically search for internet connections within range of your current location so you don't have to do any work beyond waiting a few seconds for it to find the right connections. They weigh so little and are so small that you're likely to forget you even have one on you in the first place. Truly, these modern miracles of internet technology are the epitome of the relentless and insatiable consumer desire to not be dependent on a physical location or bulky machine to get anything done. It's all about what you can take with you and use with no special preparation nowadays. So if you're a businessman on the move a lot, or even just someone who likes to travel and surf the web simultaneously, give these beauties a try.
