  What is Wget?                     Wget is a simple Linux/Unix command-line utility for downloading the contents, and files from the web. Wget will download the resource from the URL which is specified in the command. With the help of wget, we can download files using HTTP, and HTTPS. We can also download multiple files, resume downloads, recursive downloads, downloads in the background, and different options in the wget command. In this article, let’s see how to install and, use this command with examples. Installing Wget The wget is pre-installed on most of the Linux distros. To verify whether the package is installed, open your terminal type wget  and press enter. You will get a result of   wget: missing URL . If the wget package is not installed it will print wget command not found. Installation on Ubuntu and Debian                sudo apt install ...

SMART HOME - Making Living Easier A smart home is a house with internet-connected gadgets. Home automation additionally referred to as domotics is the automation of a home, typically referred to as a sensible home or smart house. Lighting, climate, recreation systems, and appliances can all be monitored and controlled by a home automation system. Home security systems, like access management and alarm systems, might in addition be enclosed. Home gadgets are a vital part of the web of Things (IoT) after they are connected to the web. Typically, a home automation system links controlled devices to a central good home hub (also referred to as a gateway). Wall-mounted terminals, pill or desktop computers, a mobile application, or an internet interface that may be accessed off-site over the net are all choices for dominant the system. While there are varied competitive suppliers, ASCII text file solutions are becoming additional well-liked. However, there are drawbacks to home automatio...

What is an IP Address? A typical IPv4 address might look like this: 192.168.1.1   You all might be wondering what are the numbers here and why these numbers are separated or divided into four chunks with 3 digits each. Okay simply put, we students get identified with a unique set of sequence of numbers called RRN. Similarly, IP Address is like a unique set of numbers that is assigned to each and every computer so that they can be identified easily. IP Address stands for "Internet Protocol Address". It helps you to develop a virtual connection between a destination and a source. What are the types of IP addresses? There are mainly four types of IP addresses, Public Private Static Dynamic Public IP Address It is a common general IP address given by the "Internet Service Provider" (ISP) to the router. It is a primary address associated with the whole network. Here every device connected to the network has the same IP. Private IP Address It is also similar to public IP ...

Surface plasmon resonance (SPR) - related science and technology have recently spawned a brand new branch of research referred to as "Plasmonics" Plasmonics, also known as nanoplasmonics, is the creation, detection, and manipulation of signals at optical frequencies at nanoscale scale metal-dielectric interactions. Following the trend of miniaturizing optical devices, plasmonics finds applications in sensing, imaging, optical communications, and bio-photonics. Surface Plasmon Resonance in Bioanalysis For almost a decade, plasmonic imaging has been used to analyze single-cell activity. Although this approach is still in its early stages, its label-free and real-time benefits have piqued curiosity, and it has already been applied to extracellular and intracellular activities. However, as a freshly developed approach, plasmonic imaging has significant flaws that must be addressed before it can be widely used. First, plasmonic imaging’s imaging capacity needs to be improved. The ...

I recently started learning Linux operating system. I have a windows machine. I searched for what are the possible ways available to work with Linux. I ended up with more ways to install Linux and work with it. WSL is one of the simplest ways to get started with Linux on windows. So, I'll be sharing my learnings about WSL. It's obvious that to learn Linux one should have a Linux-based machine to work with and execute commands. There are four possible ways to get started with Linux. Possible ways to work with Linux Building a Linux-based computer which is quite expensive. I myself don't prefer to build a machine when I am a Student. Installing and using Linux in dual boot mode with your existing Windows using a virtual box. This is one of my preferred ways but it consumes more storage. So, this too fails. And the next way is to create instances in cloud platforms like AWS, GCP, and Azure and using remotely. Also, there is no cost associated with it. Because major cloud platf...
