Comparison between Li-Fi and Wi-Fi This section is mainly dedicated for comparing Li-Fi and Wi-Fi considering various aspects. LI-FI is a visible light technology to achieve high speed wireless communication by using visible light to transfer data. It acquired this name due to its similarity to WI-FI which utilizes radio waves for transfer of data. WI-FI is great for extensive wireless coverage in buildings but has severe limitations for high density wireless information coverage in limited…

For instance I took computer fundamental classes in operating systems, programming, and database to advance in web systems development and data communications and networking. To be successful in web systems development I needed some understanding and become familiar in programming. Programming is basically learning a computer language it will allow you to tell the computer what design you want or command the computer. The prerequisites for data communications and networking would be operating…

Networking is a Broad Term, and it 's quite often related to Computers. In phrases of careers, networking is more often than not relating to community admins or computer analysts. I have dreamed of doing the latter considering the beginning of high university, and that I in the end have the resources and method to make that dream come true. Pc analysts don’t make the exceptional cash on the planet, have some difficult college lessons, and can even require more school than other laptop careers;…

developing speed of the applications and meet the requirement of their work, software engineers should love tinkering around systems and apps, and have a wide range of knowledge to figure out what makes them digitally tick. Moreover, many areas in the computer science become more and more popular, such as machine learning and cloud computing. It is obviously important for a software engineer to keep up to date with trends in digital convergence, data security, and apps. Second, software…

The internet is widely used by bilions of people everyday for various purposes including checking email, reading buletins, downloading music, social communication networking, online shopping and learning or simply accessing information about anything. Its use in educational system has seen exponential growth for the past decades (Virginia et al., 2013). “The internet has opened many possibilities for the classroom instruction but it can also be a barrier to teaching as well” (Bugeja, 2007). A…

Define/Describe of Microcomputers: Microcomputer is a complete computer designed for the individual (PC). The motherboard contains a microprocessor (CPU), Read-Only Memory and Random Access Memory, I/O ports and a bus (transmission path). Microcomputers are smaller in size than mainframes and minicomputers. (BusinessDictionary, n.d.) Types & Description Models Functions Support Multiprocessing? Environment to Used Personal computer Affordable small devices designed to be use by one person at…

everything from applications to data centres over the internet on a pay-for-use basis. Cloud computing is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. The salient characteristics of cloud computing based on the definitions provided by the National Institute of Standards and Terminology (NIST) are outlined below. 3.2 Characteristic of Cloud Computing (Peter Mell, Timothy Grance,…

into IT equipment located in public places (shoulder surfing) Stealing personal information from computers using malware, particularly Trojan horse keystroke logging programs or other forms of spyware Hacking computer networks, systems and databases to obtain personal data, often in large quantities Exploiting breaches that result in the publication or more limited disclosure of personal information such…

The two source nodes, 1 and 2, have messages A and B that need to be transmitted to the two destination/sink nodes, 5 and 6, which need both A and B to be delivered. Each edge in this network can only carry a single value. If nodes could only route/retransmit, then the central link would only be able to carry message A or message B, but not both of them at the same time. Assuming we sent message A through the center, then node 5 would receive message A twice and would never receive message B.…

CHAPTER 1 1. INTRODUCTION 1.1 WIRELESS SENSOR NETWORK (WSN): Wi-Fi sensor networks (WSN), once in a while called wireless tool and actuator networks (WSAN), are spatially disbursed autonomous sensors to monitor bodily or environmental situations, which include temperature, sound, pressure, and so forth. and to cooperatively pass their expertise through the network to a major location. The extra brand new networks are bi-directional, additionally sanctioning control of device activity. The…
