USB History - From the Seven Companies Who Developed USB
The exciting history of usb began in 1994 when the seven giant companies agreed to develop the usb technology. The seven big companies are: Inter, NEC, Nortel, Compaq, DEC, IBM and of course, the Microsoft. This group of seven successful companies did not regret. USB technology today is very popular and in demand.
What is the purpose of the invention of USB technology?
Invention is for the comfort of mankind. USB is for external devices so the main purpose of this invented usb is basically to have easier and more reliable connection between your personal computer/PC and your electronic devices (external devices, gadgets. etc.).
This is a good replacement from the multitude of various connectors on your personal computer ports at the back. Usability issues are also considered by simply configuring almost all external devices to communicate with your personal computer.
Data rates are also enhances in different versions of usb which means the latest the version of the usb, the faster it would transmit data.
Ajay Bhatt was mentioned in the invention of usb. He worked in the Intel Company. This usb by the Intel was the first usb with IC or integrated circuits to support the device. This was produced in 1995.
What was the original usb?
The first usb version is the USB 1.0 and this was released in January of 1996.
What is the transfer rate of the first usb?
USB 1.0 is the first usb with only data transfer rates of about 1.5 Mbit/s (megabits per second). 1.5 Mbit/s is for Low speed usb and for full speed usb the maximum is 12 Mbit/s.
What was the first and the most widely used usb version?
After the first usb with the version of USB 1.0, another usb made which is the USB 1.1 and is known to be the most widely used usb in the year 1998. This was released in September of the same year.
Disk drives are high-speed devices so 12 Mbit/s data rate is intended usb version for this while joysticks and lower data transfer rates used 1.5 Mbit/s rate.
The photo below is an example the most common usb plug. This is the type A plug, the usb standard.
What are the next generations of usb technology after USB 1.0 and USB 1.1?
It was April 2000 when USB 2.0 was introduced. Lucent Technologies which is now the Alcatel-Lucent, Philips, NEC, Intel and Hewlett-Packard agreed to create higher bit rates and for that they made 480 Mbit/s which is very fast of about forty times faster than the last version USB 1.1 specification.
Technology evolves so fast. After usb 2.0, USB 3.0 arrives in November 12, 2008 with a faster speed of data transfer rate of up to 5 Gbit/s and lower consumption of power but higher power output. The USB 3.0 is also compatible with USB 2.0 respectively.
SuperSpeed is a higher speed bus in USB 3.0 as parallel to USB 2.0 bus. In January 2010, new electronic devices are compatible with usb 3.0 version.
