Is your PC safe from unexpected power surges?


Suppose you are working on a large document on the desktop in your office. Next door, your co-worker is doing something similar on his laptop. Meanwhile, suddenly something went wrong in the power supply of the office building and the power supply was cut!

At the same time, your desktop screen will become a black spot. If the program you are working in does not have an auto save facility, you will lose all work since the last time the document was saved. A sudden shutdown of the power supply has the potential to damage not only the data but also the programs and hardware of the desktop.

On the other hand, your colleague working on a laptop will be relaxed. Even if their laptop is plugged into power, they will not be affected by a power supply cut. He will be able to carry on his work with ease. Even if the laptop battery is low, they will have enough time to save their work and shut down the laptop properly!

You must know the reason for this difference between laptop and desktop – laptops are battery powered. So if the battery is low and we keep it with power supply on, the battery keeps charging and the laptop runs on the power supply. If the power is cut off suddenly, the laptop system automatically shifts to battery and our work is not affected.

The good thing is that if we want, we can avail such convenience in desktop as well. The condition of power supply in Gujarat is relatively good and in a city like Ahmedabad, there is very little fluctuation or sudden supply loss in power supply, so if we do not provide additional facilities like laptop battery for desktop, but in other places, it is better to install a device called UPS for desktop .

In most offices , hospitals etc where there is a large setup of computers, Uninterrupted Power Supply (UPS) is arranged to provide uninterrupted power supply to all the computers without any interruption. UPS come in different capacities. Now many people have started installing UPS in their homes and small offices even if they have only one desktop.

This UPS works exactly like a laptop battery. When we install the UPS, let's input the power to it. The computer is plugged into a UPS instead of a direct power plug. A UPS has a battery. Which keeps charging continuously. In case of unexpected power supply failure, the UPS battery automatically activates like a laptop battery and the power supply to our desktop continues uninterrupted.

Once the power supply is restored, the desktop starts running on battery power again. If we bought a relatively cheap UPS then the desktop cannot run on battery for long. But we get enough time to properly shutdown the desktop by saving our work files.

If your town or village has problems with power supply surges or supply cuts, consider investing in a UPS to protect both data and desktops. Different capacities and types of UPS are available in the market. According to the budget , if you buy a relatively low capacity , cheap UPS, its battery may not last long. So you may have to buy a new UPS again in a year or two.

Five decades after man's arrival, 'moon trip' difficult, 60 out of 146 missions fail

Image
India tried to land on the moon in 2019 which failed. In 2023, India's space agency ISRO successfully landed on the moon. India is the first country to successfully land on the South Pole of the Moon unscathed. This success of India is also big because so far a total of 146 lunar missions have been launched out of which 60 have failed. Only four countries made a soft landing on the lunar surface According to Dr. Gail Isles of RMIT University, Australia, the Moon is the only celestial body other than Earth where humans have set foot. It also makes sense to go there first as it is our closest object at about four kilometers away. Interestingly, only four countries have made a soft landing on the surface of the moon so far. On the other hand, its South Pole is still mysterious, where only India has been able to reach. So many countries have failed Even Russia, the first country to make a soft landing on the moon 60 years ago, recently failed to land Luna-25 on the moon's sout...

A cosmological app in the palm of your hand! An exciting event took place in space yesterday - a circular solar eclipse or say 'Ring of Fire' solar eclipses! The spread of the corona virus has disrupted daily life on Earth, but everything in space is moving at a steady pace! Yesterday's solar eclipse was the result of such a fixed, fixed, annual cycle of events! We all know that the various planets in our universe revolve around the immovable sun, these planets have their own satellites. The earth itself rotates on its axis, tilted slightly, and at the same time revolves around the sun. If we talk only about the earth, due to the orbit of the earth around the sun, the motion of the earth on its own axis and the orbit of the moon around the earth, various exciting astronomical events are created. One of them is this kind of annual annular solar eclipse. Such a solar eclipse occurs when the Sun, Moon and Earth are in a straight line, all three on almost the same surfac...

The transmission power of Corona virus sticking to the surface decreases after 5 days - research

Image
London, 10, June, 2020, Wednesday It is common knowledge that the corona virus is spread from person to person through sneezing and nasal and oral droplets, as well as if the corona virus is spread on a plastic metal or other surface. There has been a lot of research on how long the corona virus survives on which surface, but the research done by the University College London in Britain is shocking. According to research published in the Journal of Hospital Infections, corona viruses can live on any surface for up to five days at most. It can spread to a large area within the first 10 hours when the transmissible power of the corona virus, which landed on the surface on the fifth day, was reduced. Observed after 10 hours, it spread to every corner of the ward. During the experiment Corona used a virus to infect artificial plants with a virus for a patient's breath that could not infect a man. Both viruses were then found in a drop of water and left on the bed railing. The viru...

Did dinosaurs that could fly in the sky live on earth?

Image
Washington, October 31, Saturday The research of Dr. yanasora research goes beyond the nitanavi information. The dinosaurs of the species called pterosaurs were the first creatures to know the art of flying in the sky. The age called Triassic lasted from 23 to 190 million years ago. Many gigantic animals existed at that time. Fossil scientists are still gathering information about reptiles that can fly in pairs. These dinosaurs preceded the T-Rex, Triceratops and Cretaceous-era dinosaurs. However, according to numerical methods, biophysical models and fossil records, terosaurs could fly superbly 150 million years ago. In the report, Joanna Baker, a professor at the University of Reading, says the pterosaur was indeed a unique creature. Gradually his flying ability was constantly increasing and improving. Scientists have discovered dozens of fossils of pterosaurs that were scattered all over the earth. The fossils of this creature range from sparrows to giraffes. The spread of its ...

IIT researchers develop real-time underwater marine robot, eases deep-sea surveillance

Image
image : Envato and Twitter Real-time underwater marine robot: Indian Institute of Technology (IIT) Mandi and Palakkad have achieved a tremendous achievement in developing real-time underwater marine robot for underwater surveillance. The function of this robot will be close underwater monitoring and verification. Its level of efficacy would be very high, risk would be extremely low and it would likely be cost-effective, the researchers said. Jagdish Kadian, assistant professor at the Center for Artificial Intelligence and Robotics at IIT Mandi, said that learning about the ocean's internal currents from history led to the conclusion that only by placing instruments on research ships deep can one gain more insight into the ocean. Kadian, a co-author of the study, said that a typical cruise ship stays on the surface for a month or two, limiting the possibility of producing a comprehensive report on the sea. So it has often been said that changes in the sea do not wait for a ship ...
