USB PortsDefinition
USB stands for universal serial port and a USB port allows electronic devices to be connected via cables to a computer. Function A USB port "allows data to be transferred between devices" (http://compnetworking.about.com/od/usbnetworking/p/usb-port.htm) as well as can be a power supply to devices that do not have their own power supply. Devices that can be plugged into a USB port and used with a computer are a keyboard, mouse, or memory stick. Description and concrete example of how it affects the end user A USB is needed in order to connect accessories to your computer, such as a mouse or printer. If your computer does not have USB ports you will not be able to connect other devices to your computer. Recommendations I would recommend getting a computer with two or more USB ports so that you will have enough ports to plug in accessories you will need to use with your computer. |
