Eabdus

2 Dec, 2021

USB (Universal Serial Bus) is a liaison media between computers and other devices such as Mouse Wireless, Keyboards, Printers, Scanners, Flash Drive, Smartphones, Modems, and others.

USB connection technology developed in the 1990s has become a tool for almost all computers and smartphones and other equipment.

Types of USB (Universal Serial Bus)

USB 2.0 was created by some of the biggest companies namely (Compaq, DEC, IBM, Intel, Microsoft, NEC, and Nortel). USB 2.0 was invented in 1996 January.

And USB 3.0 is new technology was created by the USB 3.0 promoter group (Hewlett-Packard, Intel, Microsoft, NEC, ST-Ericsson, and Texas Instruments). USB 3.0 was invented in 2010 November.

Data Rate

In terms of speed is also very different. Because they use different technology. USB 2.0 has a maximum transfer speed of up to 480Mbps, while USB 3.0 has a maximum transfer speed of up to 4.8Gbps.

The number of cables on USB 3.0 is 9, while USB 2.0 only has 4 cables.

Transfer Method

USB 2.0 uses method half-duplex (communication that occurs in data transfer can only be done in on direction).

USB 3.0 uses a method full-duplex (communications that occur data transfer can be done in both directions). So users can send and receive.
