USB is a "user-friendly" industry standard for transmitting data between a host device (such as a computer) and a peripheral device (for example, a mouse). The method simply facilitates the operation of numerous devices by attaching them via a USB connection for most computer users. Without USB, it would be difficult to connect many kinds of devices directly to a computer.
The basic concept of USB was created by Intel with their Universal Serial Bus project in 1996. Since then, it has become the de facto standard for connecting peripherals such as printers, scanners, memory keys, handheld PCs, and digital cameras to computers.
How does it work? When you plug a USB device into a computer, there's a good chance that it will show up on the desktop as a drive letter like "E:" or "F:". This is because when you insert a USB key or disk into the computer, it is actually seen as a hard drive by your operating system. The computer considers this new device to be an extension of its hard drive and makes a folder for it on the desktop.
Now when you want to use the device, you just need to click on the corresponding folder icon to access its contents from within your application software or file manager program. If there are any files on the device that you want to see, they will now be available for download into a normal directory on your hard drive.
USB, or complete universal serial bus, is a technology that connects computers to peripherals, often known as input/output devices. A USB connector allows computers to host HTML-based websites and transmit text messages as easy as... LOL. It is used for storing data on mobile phones and connecting them with a computer. USB is widely used for charging smartphones and other portable electronic devices.
The first generation of USB connectors was designed by IBM in the mid-1990s and became commercially available in 1997. Since then, almost every major computer manufacturer has shipped at least one model of computer equipped with a USB port.
The most common use for USB is to connect peripheral devices to your computer, such as printers, scanners, memory cards, and digital cameras. However, it can also be used to connect keyboards, mice, and joysticks to a computer that lacks a built-in device for these functions. Some laptops now come with only a USB port, which can be used to attach additional peripherals. These include wireless keyboard and mouse combos that allow users to move away from their desks.
Other than printers, most peripherals are connected using a standard-definition video camera. The USB port provides power to the camera's electrical components and transfers data between the camera and the computer.
USB is a mid-to-late 1990s standard that defines cables, connections, and communication protocols. This technology is intended to enable peripheral device and computer connection, communication, and power supply. It is the first generation of what is now called "Universal Serial Bus".
USB 3.0 is a recent development of this technology and is based on Light Peak technology from Apple. It promises higher speeds than its predecessors - up to 10 Gbit/s in some configurations.
Some applications of USB 3.0 are internal hard drives that are much faster than conventional hard drives - up to 5 GB per second read speed and 1.5 GB per second write speed. These devices use the new U3 technology protocol instead of the old U2 protocol that most external hard drives use today.
Other applications include digital cameras and other multimedia devices which can transfer data to computers faster than before. The older version of USB - USB 2.0 - supports up to 480 Mbit/s while the newer version supports up to 5 Gbit/s. There are still many consumer products available that use USB 2.0 only. They can connect your computer to other peripherals but they cannot be connected directly to a high speed hub or device - like a printer - because they do not support enough bandwidth.
