What is an optical fibre - Study guides, Class notes & Summaries

EC2402-OPTICAL COMMUNICTION AND NETWORKING VII SEM. ECE EC2402- OPTICAL COMMUNICATION AND NETWORKING TWO MARKS QUESTIONS AND ANSWERS UNIT I - Introduction 1. What are the limitations of optical fiber communication systems?  Optical fiber is made up of glass. Because of the impurities present with the fiber It results in absorption, which leads to loss of light in the optical fiber.  It is costly.  Maximum limitation of the bandwidth of the signals can be carried by...

A1) Benefits of pentesting - Manage risk. Increase business continuity. Minimise client-side attacks. Protect clients, partners and third-parties. Comply with regulation. A1) Pentest structure - Reconnaissance (i.e. find live hosts, sweeping, find services, scanning, banner matching, find vulnerabilities). Target prioritisation (e.g. assess servers rather than printers). Testing of services and exploitation if applicable. Consult/Confirm with customer if ok to exploit. Inform customer of any ...

Describe how a non-competitive inhibitor can reduce the rate of an enzyme controlled reaction - ANSWERBinds away from active site Changes shape of active site So no longer complementary so less substrate can bind How to identify a competitive inhibitor - ANSWERWith the inhibitor, it increases substrate conc + doesent change rate of reaction No large lipid droplets are visible with the optical microscope in the samples from suspension A. Explain why - ANSWEREmulsification Cant be seen...
