These days there are many options available for people who want accessories for their personal computer. Everything from webcams to external storage devices can be found for sale on internet websites. Most of these devices connect to the computer through a USB serial cable. This allows them to communicate with the computer, as well as receive power for certain applications.
Probably the most useful USB device is the USB thumb drive. This is a device about the size of a lighter, which can be used to store small amounts of data. This can be helpful for transferring files between computers, or for temporarily backing up information. USB thumb drives come in many shapes and sizes, some of which are designed to add a touch of personality. Another device which is commonly used is the webcam. By plugging these cameras into the computer, it is possible to record video. To connect multiple devices to a computer, a docking station can be used. Docking stations allow multiple USB devices to connect through one port. External hard drives are another device designed to connect through USB. There are even devices which power other items, such as small desk lamps and heating pads for coffee.
One of the newer innovations is an updated version of the USB standard. This new standard allows for faster data transmission. This is a boon for 2.0 video USB devices, which rely on having fast data transfer to stream video. There are many types of devices available, many of which are available online. The easiest way to get a good idea of what options are available is an internet search. With so many USB devices out there, you may just find one that suits your needs.
