Universal Serial Bus (USB) Seminar Report

Introduction to Universal Serial Bus :

It is an interface unit for transmission of data in between the devices and host computer. We can connect to low power consumption devices without the use of external power supply. USB can connect to certain devices without the use of specific preinstalled drives .it allows may peripherals connect to a standardize interface socket which improves the plug and play capabilities.

Architecture and structure:

The design of USB consists of hub, host and a device, by which the transfer of data is possible.

HUB:

The electrical interface between the host and USB is provided by HUB. It monitors the aspects like, continuity, power management, connect and disconnect direction and bus fault detection. It supports speed, which include high speed and low-speed data transmission the host HUB communication is maintained by HUB controller.

HOST:

It consists and super speed host and non-super speed host which provide the backboards capability. The super speed supports transfer of data is duplex mode. It maintains flow of control in between host and USB. It acts as a power provides to the USB device.

DEVICE:

The  device acts as source for information unchanged. These acts as pipes  through the host communicate. It allows certain functional topologies for which single function and multiple function peripheral devices can be performed. The architectural view of USB and has eight primary conducts and there twisted single pair. The different data pair cables are employed by which the transmission error can be reduced.
