Goal of the study The aim of this power point presentations Is to compare the wikipidia with Other information source.

Visualization of USB

USB definition and explanation USB stand for universal serial bus. The USB was designed to simplify the connection of peripheral devices such as a mouse or keyboard. By having a common connector, you don't need as many special connections on your computer.

USB stand for universal serial bus. The USB was designed to simplify the connection of periphial devices such as a mouse or keyboard. By having a common connector, you don't need as many special connections on your computer.

Universal Serial Bus (USB) is a specification to establish communication between devices and a host controller (usually personal computers), developed and invented by Ajay Bhatt while working for Intel. Ajay Bhatt USB is intended to replace many varieties of serial and parallel ports.serial parallel ports USB can connect computer peripherals such as mice, keyboards, digital cameras, printers, personal media players, flash drives, and external hard drives. For many of those devices, USB has become the standard connection method.computer peripheralsmice keyboardsdigital camerasprintersmedia playersflash drivesexternal hard drives USB was designed for personal computers, but it has become commonplace on other devices such as smartphones, PDAs and video game consoles, and as a power cord.personal computers smartphonesPDAsvideo game consoles power cord

Today just about every PC comes with Universal Serial Bus, or USB ports. In fact, many computers will even have additional USB ports located on the front of the tower, in additional to two standard USB ports at the back.USBports In the late 1990s, a few computer manufacturers started including USB support in their new systems, but today USB has become a standard connection port for many devices such as keyboards, mice, joysticks and digital cameras to name but a few USB-enabled devices. USB is able to support and is supported by a large range of products.

The universal serial bus is referred as USB. It is a high speed serial bus that transfers data at higher rate than that of a serial port (port that allows serial data transfers). USB allows interfacing several devices to a single port in a daisy chain for support in a wide range of peripheral such as keyboard, monitor, mouse, modem, speaker, microphone, telephones, scanner, printers, etc. USB provides power lines along with data line and contents four wires. Two out of four are used to supply electrical power to peripherals, eliminating bulky power, supply, and low power devices such as keyboard and mouse which need small amount of power get power from USB cable but the devices which requires larger amount of power eg. big loud speakers must have a local power supply. Out of four wires of USB two are used to send data and commands. USB assigns address to each devices and permits devices to communicate to one another, without involving the host. It can operate in two modes: Low speed modes that transfer data at the rate 1.5MBPS and medium speed mode that transfer data at the rate 12MBPS.

Conclusion The information that i gathered from other information source and wikipedia almost they talk the same thing, but wikipedia explian in more detail in addition to the definition.
