ASSIGNMENT 4 WEEK 1 - STORAGE DEVICES Describe the main working features of ONE of the following storage devices. Hard disk drive Optical storage Flash memory Include any relevant diagrams that help explain your answer. Optical Storage The optical storage device that most of us are familiar with is the compact disc (CD). A CD can store huge amounts of digital information (783 MB) on a very small surface that is incredibly inexpensive to manufacture. The design that makes this possible is

OCCUPATIONAL LENSES What is an Occupational Lens? An Occupational Lens (or Enhanced Reader) is a reading lens that has a Degression zone to incorporate the Intermediate prescription (and sometimes‚ depending on prescription‚ a good DV portion) Why dispense an Occupational Lens‚ instead of a Reading pair of glasses? With more and more people using Computers‚ Laptops and Smartphones‚ we demand more from the Intermediate zone than ever before. So by dispensing a pair of Reading glasses to a

INTRODUCTION Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to transmit data for telecommunications orcomputer networking. "Free space" means air‚ outer space‚ vacuum‚ or something similar. This contrasts with using solids such as optical fiber cable or an optical transmission line. The technology is useful where the physical connections are impractical due to high costs or other considerations. Free-space optical communication (FSO)

nahas | 4/29/2011 | | Free space optical communication is the most growing communication because it is easy to install and has a high speed because the signal is transmitted in the air. So that will introduce the atmospheric affect in the optical wave propagation. Atmospheric turbulence causes fluctuations in both the intensity and the phase of the received signal. So we need to study the effect and the limitation if we introduce a free space optical communication system with dual wavelength

DESCRIPTION OPTICAL MICROSCOPE Introduction The optical microscope has been a standard tool in life science as well as material science for more than one and a half centuries now. The optical microscope widely use in the field of cell biology‚ microbiology‚ biotechnology‚ pharmacology‚ forensic and medical diagnosis especially when dealing with tissue fragments. It is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. In other words‚ Optical microscope

The Optical Time Domain Reflectometer (OTDR) Introduction In fiber optic networks‚ OTDR (Optical Time Domain Reflectometer) is an opto-electronic instrument used to characterize an optical fiber. Unlike power meters OTDR does not measure loss‚ but instead implies it by looking at the backscatter signature of the fiber. Generally‚ OTDR are used to determine the loss of any part of a system‚ the length of the fiber and the distance between any points of interest. Most of the light which is

It uses C programming and the serial ports of the PCs. The ports are programmed in C. We use MAX 232 to convert RS 232 logic to TTL logic and then an optical transmitter circuit to transmit data via fiber optic cable. The optical transmitter circuit has a LED which is matched as far the cable and MAX 232 is concerned. At the receiver we have an optical receiver circuit which receives data using a photo transistor and a MAX 232 again to convert TTL logic to RS 232 for the serial port at the receiving
