Universal Serial Bus

The universal serial bus is an adapter, flash drive, and a data storage device. It got first usage in 1996 but did not get widespread usage until introduction of the iMac in 1998. The most recent version of the USB is 3.0 that has a higher data transfer rate and is backward compatible to previous USB versions. The adapter allows for plugging into electronic devices with a USB port thereby providing additional capability and connectivity. The USB flash drive provides additional storage and memory

It has increased support commercially and privately since 1996. It is complex with closely all new PC’s, it is rapidly replacing PC serial ports, and it’s focused by some of the largest manufacturers in the electronics industry

CHAPTER 1 INTRODUCTION 1.1. INTRODUCTION Portability and mobility of storage devices like flash drives and USB devices are becoming so popular to carry and transport data on the go. Unlike CD/DVD, hard drive, floppy disk or tape drive, a flash memory has no moving parts, so it guarantees fast read/write speeds and more durable compared to other forms of storage media. Using a flash drive/memory card to transfer a file typically uses a computer (e.g. laptop, pc, netbook or tablet) to initialize

PCI stands for (Peripheral Component Interconnect). It is referred as a computer bus and mainly comes in 32bit or 64bit variant. This is used by the computer to connect PCI video card, network cards, sound cards, tv tuners and etc. PCI-E Slots PCI Express stands for (Peripheral Component Interconnect Express).It are mainly used over the old PCI Slots as its very high speed serial computer expansion bus. They come in different sizes: • PCI Express x1: 18 pins (25 mm) • PCI Express x4: 32

What is a USB Flash Drive? The term USB stands for Universal Serial Bus and is used to define a special kind of connection between a computer and other electronic devices. The connections can serve different purposes ranging from power supply to communication. A USB flash drive is a storage device that acts as a portable hard drive, but generally has a much more limited capability in comparison. As mentioned, their purpose is to store digital information and to transfer information between systems

companies including Intel, Compaq, Microsoft, Sony, DEC, IBM, and Northern Telecom. They want to make a special basic device connection protocol to standardize the PC connectors; this will facilitate data transfer and connection between devices. Universal Serial Bus or better known as USB was first introduced in late 1995 and released in January 1996. Now USB flash drive has a standard set by the International Electro-technical Commission or IEC, which has

HUMAN INTERFACE MULTI-POINTING WIRELESS DEVICE Author: Dr. Sri Sai Srikanth (A.P.) SRM University, Ghaziabad g2mp16@gmail.com Abstract: This paper describes a wireless mouse that can be controlled by a user’s arm movement alone .The main purpose of this mouse is to control various computer systems by a single user.
