Technology is creating a significant impact on our lives. It is opening up opportunities for finding solutions for some of the world’s biggest challenges. Be it the new artificial intelligence technologies, immune engineering which can save the lives of cancer patients, gene editing creating sustainable methods in plants that can tolerate drought and grow resistance to disease, smart- phone applications which aid in navigation, the Tesla Autopilot, or a simple medical app which can store, analyze information and support in real-time, these emerging technologies and facilities such as WiFi are making the world more pervasive with computers and sensors.

An HD Ready TV consist of a TV that can display 720p images (1280 x 720 pixels). On the other hand, FullHD TVs are those capable of displaying 1080p (1920x1080 pixels) videos and you enjoy all lines of each frame of your video drawn on the screen. HD TV is enough if you are going to use it for the purpose of only watching HD cable TV; however, if you are a movie buff and love to enjoy movies in Blu-ray print or a gamer whose world revolves around PS3 and Xbox 360, then FulllHD TV should adorn your home.Why ...

An Event is basically defined as an action or occurrence of an action that is recognized by the software. An Event can be triggered by any of the following: a user, a system, or a remote callback. Some of the popular events include pressing a button, hovering, clicking on hyperlinks, etc.In this article, we will be exploring some commonly used JavaScript events and learning how to handle these events and execute the required tasks. To handle events in HTML, we would need to add the function in the HTML tag that will be required to be executed in JavaScript when ... Read More
In this article, we are going to explore property descriptors and how we can fetch these values from an object. The Object.getOwnPropertyDescriptor method returns an object that describes the specific property from the given object. A JavaScript object can be created in multiple ways that can be called by using the property descriptors from the object.SyntaxObject.getOwnPropertyDescriptor(obj, propThe property descriptor takes two parameters as inputs that are described below −obj − The object refers to the object name whose properties need to be described.prop − It defines the specific property from the object whose value needs to be returned.This method returns ...

Space is an empty void. It is not totally vacant, but rather comprises of a vacuum containing a very low thickness of particles, overwhelmingly a plasma of hydrogen and helium. It also consists of neutrinos, cosmic and electromagnetic rays. One hydrogen per cubic meter is the density of space.There is nothing in between galaxies and the temperature literally reaches 2.7 K, which is −270.45 °C. In the galaxies, 90% of the mass is in an unknown form, called dark matter. It interacts with other matter through the gravitational but not electromagnetic force.Manned spaceflight is limited to the lower Earth orbit ... Read More
Not all South Africans are called Proteas; it's just their national cricket team which is called by that alternate name. Protea is the name of a flower that has pink and yellow petals and it is the national flower of South Africa. It's a tradition in certain cricket playing countries to be called by names of some of their national symbols.Take the case of the South African rugby team - they are called Springboks after the spectacular antelope from the wilderness of this country, which is among the fastest land animals on earth and is known to leap up to ...

In this article, we will explore how to find the minimum and maximum values from an array without using the Math functions. Math functions including Math.min() and Math.max() returns the minimum and maximum values out of all the numbers passed in the array.ApproachWe are going to use the same functionality of the Math functions that can be implemented using a loop.This will iterate over the array elements using the for loop and will update the minimum and maximum element in a variable after comparing it with each element from the array.On finding the value greater than the max value we ...

Most of us tend to forget new information as soon as we hear it. There are times when we write down stuff and still fail to recall it within 24 hours of first reading or hearing it. Now if we consider the part of taking notes in the correct way then maybe we can retain and retrieve every bit of information we receive.Taking effective notes is a very crucial skill. This skill can become your ladder of success. It is a very effective way of learning, absorbing and recalling concepts and ideas in meetings, involving in quiz and most importantly ... Read More
Encoding and decoding the URI and the URI components is required by the URL of any website to reach or redirect the user. It is a usual task in web development, and this is generally done while making a GET request to the API with the query params. The query params must also be encoded in the URL string, where the server will decode this. Many browsers automatically encode and decode the URL and the response string.E.g., A space " " is encoded as a + or %20.Encoding a URLThe conversion of the special characters can be done by using ...

Low earth orbit (LEO) satellites systems orbit below 2000 km from the earth’s surface, i.e. below the lower Van Allen belt. They move at very high speeds and may not have any fixed space with respect to the earth.The following diagram depicts LEO satellites in their orbits.Features of LEO SatellitesA network of LEO satellites are needed for global coverage as their orbits are not geostationary.These satellites are not as powerful as the MEO and GEO satellites.Due to their high speeds, satellites move in and out of the earth station’s range from time to time. So, data is handed off from ... Read More
