Universal Serial Bus(USB)

The Universal Serial Bus or USB as we better know it is an industry standard that effectively standardized the connection of computer peripherals such as keyboards, cameras, adapters and charges to personal computers to communicate, transfer data and supply electric power. Over 6 billion USB 2.0 ports have been sold till date a 3.0 super speed versions has now become the industry norm to support transfer of data from high-end media devices that require faster transfer speeds.


Its sister, the USB flash drive has also experienced similar popularity. Introduced as a durable and faster alternative to floppy disks has completely replaced the aging floppy disk market. Furthermore, gone are the days also when USBs used to cost a month’s allowance and were only available in boring black. These days they come in every conceivable shape size and color for a fraction of the cost.


Interestinglythough, despite having the word ‘Drive’ in its name, a USB drive actually has no moving parts- it’s only because it uses the same system commands to read and write data as a traditional mechanical disc drive that this name was given to the humble USB. While the way the USB works continues to be a mystery for many, what makes it a great invention is its durability. The average USB drive can survive falls, pressures and temperatures that other devices can survive would fail under. For example, highly robust flash drives can survive being run over by 10 tons of pressure and survive temperatures of -122 degrees Celsius –mind you, don’t try that with the $10 one you bought at the thrift store.
