The universal serial bus is an adapter, flash drive, and a data storage device. It got first usage in 1996 but did not get widespread usage until introduction of the iMac in 1998. The most recent version of the USB is 3.0 that has a higher data transfer rate and is backward compatible to previous USB versions. The adapter allows for plugging into electronic devices with a USB port thereby providing additional capability and connectivity. The USB flash drive provides additional storage and memory capability for a computer. Two most useful factors of the USB is the smaller size (about 1.1 oz) and ability to plug right into a technology device (mobile computers). Almost all computers and mobile devices today comes with at least one USB port and they are very simple connection points. Also USB ports can be found in …show more content…

It is a communication method for bits traveling to the design location between input, memory, processors, and output devices. The bit also represents the physical lines over which the data is sent. The bus helps to reduce the amount of "lanes" required for communication between the components mentioned above. The bus does this by sending all communications over a single data channel. The speed at which the bus transmits data is measured by frequency (hertz) in cycles based upon transmit and receive time per second. The bus is simply a local highway. Data and address are two types of buses. The address bus provides a specific physical address and carries memory addresses needed for the processor to access in order to read or write data. The data bus pass on the required data coming and going to the processor. There is also a control bus that carries orders and synchronize signals from the control unit in route to the other hardware components. In other words, the control does the directing for information flow and identifies in what way data routing should occur through the
