What is spectrum or frequency? This is easy to understand Although the term spectrum sounds unfamiliar to many and is very technical, most people are exposed to it every day. It has become a very important part of our daily lives. Of course, the question arises, what is the frequency? And how does it affect the lives of ordinary people? Frequency is something that cannot be seen with the naked eye. It is also called an electro magnetizing field. Whether it is remote, micro web, mobile, or radio, we are coming in contact with it every day through some means. Frequency or spectrum is the amount of radiation energy that surrounds the earth. The sun is the main source of electromagnetic radiation. It also receives energy from stars and galaxies. Apart from this, such energy is also generated from the radioactive elements that are buried under the ground. Some of the frequencies we call spectrum or radiation are very useful. Which does us no harm. Through which we can listen to the radio. W

India creating its own map as an alternative to Google Maps

India creating its own map as an alternative to Google Maps India is planning to create a separate map as an alternative to Google Maps. For that, India's space agency has collaborated with 'Mapmai India'. The map may India is a tech company working on digital map data of India. India has launched another app as an alternative to Twitter and WhatsApp and is also preparing to build an alternative to Google Maps. India Space Researcher and Mapmai India informed about this project on Friday. He did not say when the service would be made public. However, the collaboration of the India Space Research Organization and Mapmai India on the project will make a significant contribution to India's mapping system. It is said to be much better and more informative than the currently available map. "It will always protect user privacy and provide the country's own mapping solution," said Rohan Burma, CEO of India Space Research Institute.

'Supply Chain Attack' on 35 Big Companies including Microsoft, Apple, PayPal An ethical hacker (researcher) has recently demonstrated a novel supply chain attack. Accordingly, the systems of more than 35 big technology companies like Microsoft, Apple, PayPal, Sophie, Netflix, Tesla, Uber have been breached. Novell Supply Chain Attack exploits public and open-source developer tools. The system, developed by ethical hacker and cybersecurity researcher Alex Birsan, injects malicious code into an open-source developer tool to exploit the dependencies of those organizations' internal applications. It could target developers' projects using public depositories such as GitHub. According to Birsan, the success rate of such attacks is high after the companies have been targeted. The vulnerabilities he has exploited so far, which he calls 'Dependency Confusion', have been found in more than 35 organizations. These were in Python, Ruby, and Java programming languages.

Here's how to put one together for use with a quantum computer Many of you may have heard of supercomputers. But have you ever heard of a quantum computer? If some have heard this word somewhere then you are lucky. Because you have the good fortune to listen to the modern technology of the modern age. Today we will tell you what a quantum computer is and how it works. To understand a quantum computer, first remove all the elements inside the computer such as a keyboard, mouse, motherboard, hard drive, RAM, graphics card. And look at the things that have helped make your computer a computer. Whether it's a computer or a mobile phone, the processor is what makes your device so smart today. The smallest element in that processor is the transistor, whose particles combine to form a single processor. The transistor acts as a switch to turn the current on and off. There are billions upon billions of such switches inside a computer. Once you get all those switches, you can perform all

What is quantum internet and how is data transferred from it?

What is quantum internet and how is data transferred from it? Quantum Internet begins where the capacity of our normal computer or Internet is limited. For example, today's computers have a processor based on seven-nanometer lithography. After a while, it decreases to five, three to two. Then it is difficult to reduce the size. Because the size of the transistor inside the processor is about the size of an atom. Then our internet is transferred to the quantum world. Where our normal physics don't work. Quantum computers are born to meet the limitations of ordinary computers. It has high cybersecurity. Because it is transferred to the superposition. With the advent of a quantum internet, you don't have to use encryption like you do now. The speed of quantum internet is much faster than the normal internet we use. According to scientists, its data transfer rate is one GB per second. Quantum Internet was discovered by Chinese scientists. When two places with a distance of 40 k
