Drivers

For some peripheral devices, you may need to load drivers before connecting the device for the first time. Drivers contain software instructions that the computer needs in order to communicate with the device. For many devices, the necessary drivers are included with the operating system. Other devices may require you to manually install the drivers on the system prior to the first connection. Device drivers may also need to be updated when manufacturers fix bugs and vulnerabilities.

Explain what each USB connector is designed for

The most commonly used type of connector is the Universal Serial Bus, or USB connector. USB allows you to connect a variety of external devices, including printers, digital cameras, external hard drives, and smart phones. Type A USBThey are designed for connections that may be plugged and unplugged frequently. Type B USB They are designed to be used for connections that are left plugged in for long periods of time. Mini USB connectors are a smaller type of USB connector. They are commonly used for devices such as digital cameras. Micro USB connectors are even smaller still. They are commonly used for connections to mobile devices, such as tablets and phones.

Self Powered USB Devices

USB ports can provide power over the connection. USB devices can receive up to 500 milliamps of power from a USB 2.0 port and up to 900 milliamps of power from a USB 3.0 port. If a device can operate on this much power, it's considered a bus-powered device, which means the USB port provides 100 percent of its power. If a device needs more power than this, it's considered a self-powered device and will typically have an external power adapter that plugs into a wall outlet.

USB

USB devices are hot-swappable. This means you can plug and unplug USB peripherals while the system is running. The system will automatically detect the addition or removal of a device and make the necessary configuration changes. Before disconnecting external storage devices, you need to 'stop' them properly in the operating system before removing them to prevent data corruption. USB devices can be plugged in directly to a USB port on the computer or to an external USB hub that's connected to the computer.
