Green Computing Green computing is the environmentally responsible and eco-friendly use of computers and their resources. In broader terms, it is also defined as the study of designing, manufacturing/engineering, using and disposing of computing devices in a way that reduces their environmental impact. Green computing, Green ICT as per IFG International Federation of Green ICT and IFG Standard, green IT, or ICT sustainability, is the study and practice of environmentally sustainable computing or IT. Green IT is the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystemssuch as monitors, printers, storage devices, and networking and communications systems efficiently and effectively with minimal or no impact on the environment. History The term “ Green Computing" was probably coined shortly after the ‘ Energy Star’ program began way back in 1992. One of the first results of green computing was the “ Sleep mode” f

Robot Master: Robot Master is a name used to refer to human-like boss robots from the original Mega Man series that possess a very advanced level of artificial intelligence. Most, if not all, Robot Masters possess a Special Weapon. These powers can be gained mainly by Mega Man, Proto Man, or Bass after the robot is defeated. Each Robot Master has a "consciousness", although the level of every "cognitive circuit" embedded inside each one of them varies, producing as many different "personality" types as found in people. Like humans, they can speak, and have emotional responses like shyness or anger. When Mega Man fights against a Robot Master, he takes great care to not damage their integrated circuit chip's "cognitive circuit". As long as the cognitive circuit isn't completely destroyed, they can be rebuilt any number of times. Robot Master is a special kind of robot or android that possesses a very advanced level

Computer virus:  A computer virus, much like a flu virus, is designed to spread from host to host and has the ability to replicate itself. Similarly, in the same way that viruses cannot reproduce without a host cell, computer viruses cannot reproduce and spread without programming such as a file or document. A computer virus is a program or piece of code designed to damage your computer by corrupting system files, wasting resources, destroying data or otherwise being a nuisance. Viruses are unique from other forms of malware in that they are self-replicating capable of copying themselves across files or other computers without a user's consent. History of computer viruses: The first computer virus to be discovered in the wild was "Elk Cloner," which infected Apple II operating systems through floppy disks and displayed a humorous message on infected computers. Elk Cloner, which was developed by 15-year-old Richard Skrenta in 1982, was designed as a prank

Backup:  An additional copy of data or information stored on secondary storage media is called the back up data.  In information technology, a backup, or the process of backing up, refers to the copying and archiving of computer data so it may be used to restore the original after a data loss event. The verb form is to back up in two words, whereas the noun is backup  The common media for backup are zip disks, magnetic tape, floppy disk, CD-ROM and hard disk etc. Types of backup: Full backup: Back up all data on the hard disk is called complete backup or full backup. The advantage of this back up is that the entire hard disk is backed up. The data can be restored from this backup case of a problem in system. Incremental backups:   Incremental backup create a copy of only the data that is newly create or modified since the last backup. This process is preformat automatically in some software. In this type of backup the entire disk is not copy. It takes less time and space then

Freelancing: A freelancer or freelance worker is a term commonly used for a person who is self-employed and is not necessarily committed to a particular employer long-term .  Freelance workers are sometimes represented by a company or a temporary agency that resells freelance labor to clients; others work independently or use professional associations or websites to get work. While the term "contractor" would be used in a higher register of English to designate the tax and employment classes of this type of worker, the term freelancing is most common in culture and creative industries and this term sindependent pecifically motions to participation therein. Etymology: Although it is commonly attributed to Sir Walter Scott (1771–1832) in Ivanhoe (1820) to describe a "medieval mercenary warrior" or "free-lance" (indicating that the lance is not sworn to any lord's services, not that the lance is available free of charge), a previous appearanc

Application software: Application software is a program or group of programs designed for end users. These programs are divided into two classes: system software and application software. While system software consists of low-level programs that interact with computers at a basic level, application software resides above system software and includes applications such as database priograms, word processors and spreadsheets. Application software may be grouped along system software or published alone. Examples: word processor, a spreadsheet, an accounting application, a web browser, a media player, an aeronautical flight simulator, a console game or a photo editor etc. Design:                                                                                 Types  Application Suite: Has multiple applications bundled together. Related functions, features and user interfaces interact with each other. e.g. Microsoft Office, LibreOffice and iWork, which bundle together a wo

Holography: Holography is the science and practice of making holograms. Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics. The hologram itself is not an image and it is usually unintelligible when viewed under diffuse ambient light. It is an encoding of the light field as an interference pattern of seemingly random variations in the opacity, density, or surface profile of the photographic medium. When suitably lit, the interference pattern diffracts the light into a reproduction of the original light field and the objects that were in it appear to still be there, exhibiting visual depth cues such as parallax and perspective that change realistically with any change in the relative position of the observer . History: Holography dates from 1947, when Briti

Samsung S9 | S9+: The Samsung Galaxy S9 and S9+ is a great phone, but one that hasn't really kicked on from the Galaxy S8, bringing a very similar design and screen to 2017's version. The improved biometrics were sorely needed, and the camera is a leap forward, but the amazing low light capabilities have resulted in sacrifices elsewhere. A top, top phone, but the S9 Plus outshines it. The Samsung Galaxy S9 and Samsung Galaxy S9+  are Android smartphones produced by Samsung Electronics as part of the Samsung Galaxy S series. The devices were revealed at the Mobile World Congress in Barcelona on 25 February 2018. The Samsung Galaxy S9 is the phone that's supposed to lead the charge where the Galaxy S8 , one of the best phones we've ever tested, left off - but it's not as much of an upgrade. Improved biometrics: The speed of the Intelligent Snan feature is so much better than last year... where the iris scanner and facial recognition on the S8 wer

DelFly:           The DelFly is a fully controllable camera-equipped flapping wing Micro Air Vehicle or Ornithopter developed at the Micro Air Vehicle Lab of the Delft University of Technology in collaboration with Wageningen University.    In 2005 a group of 11 students completed their Bachelor studies by making a first design for the DelFly. It was designed to take part in an international MAV competition in Germany. With their design they won the Symposium for Bachelor thesis projects of the faculty of Aerospace Engineering . The team of students and their supervisors built the first DelFly I with a wing span of 50 cm and a weight of 21 grams and joined the competition in Germany. The jury was very impressed by the unique design of the MAV, that was able to fly both fast and slow. while also carrying a camera onboard. A follow up design was made in 2007, resulting in DelFly II, with 28 cm wing span and a weight of 16 grams. This design thereby not only smaller and lighter, bu

SPEED Airwolf 3D AXIOM models operate at printing speeds of up to 250 millimetres per second, and travel speeds as high as 400 millimeters per second. At Airwolf 3D we understand that time is critical, and this is why we have developed one of the fastest desktop 3D printers on the market. SIZE Size limitation is currently a major drawback with most 3D printers on the market. Not at Airwolf 3D. With a huge build platform, the AXIOM series can print large models without having to print in multiple pieces. ACCURACY With a 40 micron minimum layer height, and an X, Y resolution of 20 microns, the AXIOM series printers are extremely accurate. Airwolf 3D has worked hard on balancing resolution and speed, and has come up with a system that provides the best of both worlds. DURABILITY At Airwolf 3D, we don’t only make and sell 3D printers, but we also use them as a tool on a daily basis for our own production line. This requires a durable machine that requires little maintenance. We hold th

                Robotic Fish:         SoFi is a fairly small robot, about a foot and a half long and weighing in at just 3.5 pounds. A hydraulic pump moves water in its soft rubber tail from side to side, allowing it to swim in a fish-like motion. Electronics including a Linux PC, along with a fisheye lens, are stored in the robot's head. It runs off a small battery similar to what you would find in your smartphone, and in its current iteration it can swim for about 40 minutes at a time. A robot fish is a type of bionic robot, which has the shape and locomotion of a living fish.MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have built a fish robot that can swim in the open water alongside the very animals it is researching. Robotic fish have become increasingly sophisticated in recent years. They are now "secret agents" that can infiltrate schools of fish in controlled scenarios. The new CSAIL robofish called SoFi appear

Innovation:                    A new idea, device or method. However, innovation is often also viewed as the application of better solutions that meet new requirements, unarticulated needs, or existing market needs. This is accomplished through more-effective products, processes, services, technologies, or business models that are readily available to markets, governments and society. The term "innovation" can be defined as something original and more effective and, as a consequence, new, that "breaks into" the market or society. It is related to, but not the same as, invention, as innovation is more apt to involve the practical implementation of an invention (i.e. new/improved ability) to make a meaningful impact in the market or society, and not all innovations require an invention. Innovation is often manifested via the engineering process, when the problem being solved is of a technical or scientific nature. 10 Ways You Can Innovate at Work Every Sing
