Principal’s Message: Education plays a significant role in breakingthe shackles of ignorance. It offers knowledge, knowledge thatis not merely bookish or tutored, but the knowledge thatenables us to achieve original understanding. Educating students is part of the college’sfundamental mission. While working with them, I discover inmany cases their education, stretch beyond the classroom andprepares them for careers and professional life. While ourcollege’s programmes are rigorous, additional professional andpersonal growth results from experiences outside theclassroom- in plant trainings, clubs and competitions. Updating new skills have become the order ofthe day. Only a person willing to learn new things can see theproblems and challenges in their right perspective and offerlasting, sustainable and comprehensive solutions. A rare combination of youth and technology isdriving a wave of change in the developing nations. Ourcountry is heavily dependent on youth power. With this inmind, we encourage each member of our educational systemto work together to provide the highest quality educationalprogram possible. I am proud to state, \"Kamaraj College ofEngineering & Technology is a positive place where everyonelearns and succeeds. We believe in the philosophy \"Teamworkmakes the dream work.\" Dr.Anant Achary

LI-FI: LIGHT FIDELITYLiFi is a wireless optical networking technology that useslight-emitting diodes (LEDs) for data transmission. LiFi isdesigned to use LED light bulbs similar to those currently inuse in many energy-conscious homes and offices. However, LiFibulbs are outfitted with a chip that modulates the lightimperceptibly for optical data transmission.Capable of 10gigabits-per-second (Gbps),which is fasterthan 802.11ad.The increasing demand for higher How Li-Fi Worksbandwidths, faster and more securedata transmission as well as The only difference is thatenvironmental and undoubtedly the former has the abilityhuman friendly technology heralds to transmit data almostthe start of a major shift in wireless ten thousand times fastertechnology, a shift from RF to optical than the latter .technologies. An LED light bulb anyone at all, can be flicked on and off in order to be able to generate signals.

Benefits of Li-Fi: Higher speeds than Wi-Fi 10000 times the frequency spectrum of radio More secure because data cannot be intercepted without a clear line of sight Prevents piggybacking Does not create interference in sensitive electronics, making it better for use in environments like hospitals and aircraft By using Li-Fi in all the lights in and around a building, the technology could enable greater area of coverage than a single Wi-Fi router Technology uses Visible light spectrum that has still not been greatly utilized Since light cannot penetrate walls, it provides privacy and security that Wi-Fi cannot Li-Fi has low implementation and maintenance costs It is safe for humans since light, unlike radio frequencies, cannot penetrate human bodyDisadvantages of Li-Fi Technology Communications only Presence of Light is essential There should be line of sight These signals cannot penetrate walls. So if you want to movefrom one room to another, you will need to have a wired bulb present in that room as well Only works if there is direct line of sight (LOS) between thetransmitter and receiver - Ms.V.

Cloud computing Cloud computing is a type of computing that relies onsharing computing resources rather than having local servers orpersonal devices to handle applications.A cloud can be private orpublic. A public cloud sellsservices to anyone on theInternet.(Currently,Amazon web service)When a service provideruses public cloudresources to create theirprivate cloud, the resultis called a virtual privatecloud.Categories of Cloud Computing: There are mainly four models of cloud computing: 1. Infrastructure as a Service (IaaS) 2.Platform as a Service (PaaS) 3. Software as a Service (SaaS) 4. Network as a Service (Naas)

Advantages of Cloud Computing: • Cost Efficiency • Convenience and continuous availability • Backup and Recovery • Cloud is environmentally friendly • Resiliency and Redundancy • Scalability and Performance • Quick deployment and ease of integration • Increased Storage Capacity Disadvantages of Cloud Computing: • Security and privacy in the Cloud • Dependency and vendor lock-in • Technical Difficulties and Downtime • Limited control and flexibility • Increased Vulnerability Conclusion Despite its disadvantages and the fact that it is still in an infant age, cloud computing remains strong and has great potential for the future. - Mr. T.K.V. Vikram SecondYear FACT The first practical microchip was developed in the late1950s, and once computers could do more complexcalculations, people started developing programs for businessapplications.

YOUNGEST CEOs:• Shravan (10) and Sanjay Kumaran (12), two brothers from Chennai have created mobile phone applications that have witnessed over 10,000 downloads across the world already are India’s youngest entrepreneurs• Shravan, is the president and Sanjay, is the CEO of Go Dimensions, an app development unit that they founded two years ago from their bedroom in their home in Chennai• In the past two years the two have developed eleven apps that are available on the Apple App Store and Google's Android Play Store• The apps have received over 35,000 downloads. Their first app -- Catch me Cop on the Apple App Store -- was released last year and was a hit• Abdul Kalam (former president of India) once came to our school and he loved playing Catch me Cop,\" recalled Sanjay Since the two are less than 18 years, Go Dimensions cannot be registered in their names as per Indian law. So the registration is in the names of seven of their family members who are above 18• Today, a spare room in their Chennai home is a digital lounge filled with Apple Macs, iPads and Samsung Galaxy Notes. The ''after homework hours'' are spent on coding and debugging test apps, while nibbling on cheese fritters and lasagna• Recently, they launched an action game called Extreme Impossible 5 or EI5

• They learnt to code on Java by reading books and information available on the internet. Programming on Apple's iOS required a bit of handholding from their dad According to their web site GoDimensions.com, they create applications 'primarily in the area of education, games, lifestyle and convenience’• Some of their popular applications include Alphabets Board, Colour Pallatte and Catch Me Cop among others• The brothers are currently working on another application with an Olympics torch which will be surely appreciated by the people world-wide - Ms. T.Porkalai Devi ThirdYear Sudoku Here's a 'classical' Sudoku puzzle. The grid is further divided by the darker lines into nine 3 X 3 square 'boxes'. Some of the squares already have numbers in them. Rules: Each row, column and box must end up containing all of the numbers from 1 to 9. Each number can only appear once in a row, column or box.

Solid State drive• Solid State drive (Is also known as electronic disc) is a nonvolatile storage device that stores persistent data on solid state flash memory• SSD has an array of semiconductor memory organized as a disk drive, using integrated circuits (ICs) rather than magnetic of optical storage media• SSDs are lighter, faster, and use less power than hard drives because they have no moving parts• It has write speed up to 2800 Mb/s and read speed up to 2000 Mb/s• Unlike hard drives, SSDs use flash memory chips to store trillions of bits of information• Most SSDs use NAND-based flash memory, which retains data without power• I/O interfaceslike SATA Express arecreated to keepup with speedadvancements inSSD technology• Intel S3700 Series 800 GB SSD costs Rs 1,25,500 in flipkart - Mr. A. Santhosh Kumar SecondYear CSE FACT The paths in these circuits are five thousand times narrow than the human hair

TeSt YoUr BrAiNProblems on trains:Moving train Rule 1 : When two trains are moving in opposite directions,then relative speed will be the addition of their individual speeds. Rule 2 : When two trains are moving in same direction, thenrelative speed will be the subtraction of their individual speeds. Rule 3 : On passing a platform by a certain train the netdistance traveled is the sum of length of train and the length ofplatform both. Rule 4 : When a train passes through a pole or personstanding, net distance traveled to pass is the length of the train.Questions: 1. A train 120 m long is running at the speed of 54 km /hr.Find the time taken it to pass a man standing near the railwaytrack. 2. A train is moving at a speed of 54 km / hr. If the length ofthe train is 100 meters, how long will it take to cross a railwayplatform 110 meters long? 3. Two trains 125 m and 100 m in length respectively arerunning in opposite directions, one at the rate of 50 km / hr andthe other at the rate of 40 km /hr. At what time they will cleareach other from the moment they meet ? 4. Two trains 110 m and 100 m in length respectively arerunning in same directions, one at the rate of 100 km / hr and theother at the rate of 64 km / hr. At what time faster train will clearother train from the moment they meet?

Solutions: 1) speed of train = [54 * ( 5 / 18 ) ] = 15 m / sec length of train = 120 m , So required time : Time Taken: (120/15) = 8 sec 2) speed of train = [54 * ( 5 / 18 ) ] = 15 m / sec Distance covered in passing the platform = 100 + 110 = 210 m Time Taken = (210/15) = 14 sec 3) Relative speed of trains = (50 + 40) km / hr = [90 * ( 5 / 18 )] = 25 m / sec Total length to be travelled = 125 + 100 = 225 m Time Taken = (225/25) = 9 sec. 4) Since trains are running in same direction, so relative speed = 100-64 = 36 km / hr = [ 36 * ( 5 / 18 )] = 10 m / sec Total length to be traveled = 110 + 100 = 210 m Time Taken = (210/10) = 21.
