The brain-computer interface

The brain-computer interface, through which the brain will now directly control the electronic device


It may seem strange to you that in the future you will be able to control any device including mobile, computer, laptop directly from your mind without touching it. Of course, you may have seen Dr. Octopus in the movie. In the film, there are many hands of Dr. Octos's machine.




Dr. Octopus controls the hands of these machines with his brain. You may not believe that all this is possible even in real life.



But it is really possible. Brain-computer interface technology now makes it possible to control electronic devices.



After all, what is this brain-computer interface?

Today we are going to tell you what is this brain-computer interface and how it works. You will also find information on its usefulness.


The brain-computer interface is easy to understand if it is a kind of machine or a kind of system. Which connects our brain to the computer and sends the brain's instructions to the computer.



We can even recognize it by another name NCI. Whose full name is Neural Control Interface? To make it easier to understand, such a machine or system, through which the information of our brain can be displayed on the screen of a computer or electronic device. In fact, the system allows you to communicate or give instructions directly to the commuter.


Knowing this, you must have found it interesting and unique. Now let's talk about how it works. To understand the brain interface commuter interface, let's take an example from real life.


Most people know how our brains work. If you know that, you can easily understand this brain-computer. In particular, our brain uses electric pulses to exchange information and instructions with different parts of the body.


This is what we can think with the help of electric pulse and signal. Can work We can dream In this way our brain can do different kinds of things.


Similarly, if you have a general knowledge of computers, the computer also works on the basis of electric signals. From which the computer works based on the instructions we give you.


The electrical signals that work on a computer are zero and one digit in binary form. Now the thing to understand here is that the commuter also works from the electric signal and the brain also uses a kind of electric signal.


Now, in this case, we can make a connection between the two. This means that if we can transmit the kind of electrical signal emanating from our brain to a computer through a system or machine, then the computer can understand the language of our brain.


How much fun would it be to have this very interesting topic in real life? Scientists have completed various tests. The first test was performed on a monkey.



In which some pins were attached to the monkey's head and it was connected with a wire. In this test, the monkey was found to be able to control the robotic arm.


This is exactly what you are looking for in a Doctor Octopus movie. He can move the hands as he pleases without speaking the hands of the machine attached to it.



Now the brain-computer interface technology has become not just a fictional story of the film, but a real-life experiment. In the days to come, this technology will definitely be developed to a more advanced level.

What to do when water enters the mobile?

What to do when water enters the mobile? You know, it's awkward


The rainy season is now underway. It is raining continuously in different parts of the country. But even during the rainy season, people have to go out of the house. In this way, some of us get soaked with water.



At the same time, the smartphone we have with us also gets wet. Sometimes our phone falls into the water by a small mistake. So today we are giving you some tips on what to do and what not to do if your smartphone gets wet in the rainy season.




The first thing you do when your phone is wet or in the water is to turn it off if your smartphone is on. Do not try to press or turn on any button after closing. Doing so will reduce the risk of short circuit in the phone.



If you have an old phone and it has the facility to remove the battery, easily remove the battery, memory card and SIM card. If the phone has a non-removable battery, there is a risk of a shirt. Now dry the phone under a fan or through a hair dryer (blower). Wipe the water on the phone with a cloth or paper napkin.


If you do not have a hair dryer, place the phone in the middle of dry rice. But keep in mind that rice nuts can go in through the headphone jack. Leave the phone to dry for at least 24 hours. This is the most useful and easy way to dry a wet phone.



Now take the phone out of the rice and turn it on. If the phone is not turned on, charge it. If the phone still does not open, go to the nearest mobile phone manufacturing center or related service center.

Have you filled out an online form? If you are insecure, Chrome will now issue a warning

Have you filled out an online form? If you are insecure, Chrome will now issue a warning


We often fill out a variety of forms on online platforms. Some of them are necessary and some are filled due to temptation. Hackers may be collecting personal information through the form we fill out.



We have never been aware of such a thing. Now Google Chrome is warning users to fill out the form.



If you're filling out a form and submitting it online, Chrome will let users know how secure such forms are.



If the form to be filled out is unsafe, you are warned that this platform is unsafe, do not submit the form.


Google says its purpose is to prevent users from sharing important information arbitrarily. It is mentioned that this feature will be available to the users through Chrome M86 version.

The 25-year journey of Internet Explorer is coming to an end

 The 25-year journey of Internet Explorer is coming to an end


We should all be using Internet Explorer, a product of Microsoft. The 25-year journey of Internet Explorer, the most used search browser in the early stages of the Internet, is now coming to a complete halt.


Everyone has their own experience in using it. However, the company has made an unpleasant decision to shut it down due to the recent loss of users due to the popularity of other browsers.



Microsoft will stop supporting it from August 17, 2021. According to Microsoft, Microsoft 365 App & Services will no longer provide services to Internet Explorer from next year.



As an alternative, the company has been promoting Microsoft Edge for the past few years. Which is now established as the world's second-largest web browser.


In 2015, the company created Microsoft Edge through the open-source Chromium for Google Chrome. Which has many features compared to Internet Explorer. It is also user friendly.


Google prepares for 6 GHz WiFi test


Google has asked the US government for permission to test the GHz spectrum for high-speed Wi-Fi. The company has sought permission from various state governments to test the technology, which is seen as a new generation of WiFi technology.



Google is preparing to test it in major US cities in the first phase. The company has also sought permission from the government to test the six GHz WiFi, which is expected to affect other WiFi signals.



This technology will run at twice the speed of WiFi currently available. Similarly, the coverage area of ​​WiFi will also be more.



Currently, 2.4 GHz and 5 GHz band WiFi is in vogue in the global environment. Five GHz WiFi has just come into use in Nepal. After some time, a big change is appearing in WiFi.


With two decades of major upgrades to WiFi, this will change


After some time, a big change is appearing in WiFi. The US Federal Communications Commission has announced that it will open a plot of 6 GHz spectrum for use without a license.



Such a change would allow the user to broadcast the router above the 2.4 GHz and 5 GHz bands. So your router will have more open-air routes to broadcast WiFi signals.



Next year when this new spectrum will be officially opened for business, users' devices will run faster, connections will be more reliable than the previous generation.



Since the Federal Communications Commission made provision for Wi-Fi in 1989, the decision will add a wide spectrum. This new spectrum has further increased the amount of space available for routers and other devices. As a result, any device will have more bandwidth and less interferer.


"This is the biggest decision in the history of WiFi spectrum in twenty years," said Kevin Robinson, marketing leader of the WiFi Alliance, an industry group that oversees the implementation of WiFi.



By the end of 2020, the devices are expected to support 6 GHz WiFi. Therefore, its implementation is not far away. When it arrives, it will be branded as WiFi Six E.


How can this help our weak WiFi?

If your device has trouble connecting to the WiFi network, it may be due to spectrum congestion. When you connect multiple devices with the same band frequency, the network drops on some devices.


If you see many WiFi networks in your area, now consider for yourself why your connection is slowing down. The reason is simple, your computer is competing with many signals.


6 GHz can solve this problem for you. This allows your router to accommodate so many new airwaves that the signals of the WiFi channels never overlap like they do now.


This new spectrum has enough rooms for a maximum of seven WiFi streams. All streams can be broadcast at GHz without interruption without using the previous spectrum.


FCC is opening a 1200 MHz spectrum in the 6 GHz band. For the past two decades, WiFi has been operating in 400 spectra. Within that limited space, all available channels were being split.


Within the 6 GHz band, each channel is expected to be 160 MHz in size. But currently available space can only accommodate two channels of this size.


6 GHz WiFi

Not everyone knows how WiFi works. WiFi works by transmitting airwaves. The airwaves are open to everyone's use.


Today, it operates in two bands, 2.4 GHz and 5 GHz. Now the third band 6 GHz has been added.


Depending on the band's number, their features also vary. 2.4 GHz flows very fast and 6 GHz provides fast data.


It does not matter what specific frequency is used. The important thing is the space of the available airwave.


It has a lot of 6 GHz space. The space of the new band is more than the overall WiFi space available before.
