up with a solution he calls “data through illumination” –taking the fibber out of fiber optic by sending data through an LED light bulb that varies in intensity faster than the human eye can follow. It’s the same idea band behind infrared remote controls but far more powerful. Haas says his invention‚ which he calls DLIGHT‚ can produce data rates faster than 10 megabits per second‚ which is speedier than your average broadband connection. He envisions a future where data for laptops‚ smart phones‚

COMMUNICATION AND COMPUTER NETWORK 4.1 INTRODUCTION Today computer is available in many offices and homes and therefore there is a need to share data and programs among various computers with the advancement of data communication facilities. The communication between computers has increased and it thus it has extended the power of computer beyond the computer room. Now a user sitting at one place can communicate computers of any remote sites through communication channel. The aim of this chapter

have been used to maintain a wireless link between the two computers. The PC on the transmitter side first transmits the data serially to the microcontroller with the help of voltage converter (MAX232) at an adjusted baud rate. This data is then transmitted to the microcontroller on the receiver side with the help of the wireless link maintained by the RF module. This received data is then sent to the receiver PC serially. The RS-232 cable (DB-9 connector in this case) is used to coordinate the serial

Introduction to Big Data In 2012‚ the concept of ‘Big Data’ became widely debated issue as we now live in the information and Internet based era where everyday up to 2.5 Exabyte (=1 billion GB) of data were created‚ and the number is doubling every 40 months (Brynjolfsson & McAfee‚ 2012). According to a recent research from IBM (2012)‚ 90 percent of the data in the world has been

Smith Elimination of errors during transmission is controlled by hardware and software. There are two categories of network errors when it comes to data; Corrupt data‚ data that has been changed during the transmission and Lost data‚ data that does not reach its final destination. When you design a network it should be constructed to prevent‚ detect and correct both the corrupt as well as the lost data errors. Network errors are inherent part of data transmissions and can occur with varying frequencies
