The Information Age is an era of technology innovation. Digital items such as computers and HDTVs are being improved right after an effective technology was created. Enter USBs. Universal Serial Bus or USB was developed in 1995 to standardize all computer peripherals; thereby replacing the old parallel and serial ports found in older PC models. It can act as an interface to connect almost anything. One is not required to shutdown his or her computer to connect or disconnect a USB-enabled device. Its goal is to allow shared access between low speed and high speed bus activity without compromising quality of the flow. USB shouldn’t be called a serial port since it can connect to a myriad of devices. A serial bus is a hub for all these connections; hence the term. Now nearly every PC has one or more USB ports.
We can now say that the USB is a small networking system. USB-enabled devices include audio systems, Internet connectors, Human Interface Devices, Printers, Mass storage units, etc. These are evidences that USBs will become the ultimate standard of PCs in the future. USBs are designed to be robust and can take in data without compromising quality. There have been many versions of USB in history. There’s USB 1.0 in 1996 running at 12 Mbit/sec, USB 2.0 in 2000 with 480 Mbit/sec and finally USB 3.0 with 5Gbit/sec in 2008. There is a high probability of USB 4.0 version coming out soon. But so far, no official reports have been given yet. It is expected that its connection speed will be much higher than its predecessors.
