  Linux -based distributions are built-in many type of tools and security testing software. These operating systems are primarily designed to test security flaws, so hackers or those who think about, or work with, the security of the cyber world are generally more comfortable using these operating systems.And among these, Kali Linux and Parrot GNU / Linux are a little more popular, because their community system is relatively strong and they always keep the tools updated within few times And good programmers usually use GNU / Linux based distributions, not special distributions, but if someone is interested in hacking and programming, they might use these special security distributions..The reason for using GNU / Linux based distribution for programming is that its source code is open, programmers have the opportunity to read and modify the source code of the software here, even modify the programs if they want, and distribute. These are the main principles of the GNU project. Free...

The number of online based companies and companies providing services through websites is currently innumerable. Big companies like Google, Facebook, Twitter have arranged for their services to be displayed on third party sites to keep them at bay.If you have visited many websites, you must notice that the articles are on that site but there are direct Facebook comments added, that is, Facebook comments can be made on the articles of the website and the comments are also published on Facebook. Again, you can see the latest posts on Twitter from the website, all of which are made possible by the API.   You can see in Twitter that you can login using Facebook or Google account, how does it work? Kora is directly connected to Facebook, Google's user database, when a user logs in through Facebook, Facebook provides Kora with the details of that user and logs in to Kora. In this, all the work is done with one account of yours. The main purpose of API is to improve the quality of service...

 Have you ever wondered how computers, various software, and the websites you visit communicate with each other? Why websites need to be connected to each other; Suppose you want to book an airline ticket from a website, then you have to go to the website of that airline and book a ticket.But there are many websites that are connected to the websites of many more airlines and you can book all the airlines tickets from one website. Again, those who shop online surely know that there are many websites where you can compare and check the product prices of all e-commerce sites from one website, so how do these sites stay connected to more than one site at a time. To fully understand this you need to know about API!  It is the simply explanation of definition like what does api means . Now we are talk about with  "what is api and how does api work ". The full form of API is the Application Programming Interface. As a normal user it is never possible to understand its function ...

There are some .dll files in Windows that are used by different applications for the same purpose. Now if you update or install an application so that the corresponding .dll file can be modified, it may be difficult for other applications that are using the same .dll file to work. Because the .dll file has been updated, but the applications do not know it, so they are working on calculating the old .dll file.For this reason, the system is rebooted, all applications are closed and the system is restarted, so that everyone can use the new .dll file after the restart.   Linux-based operating systems deal with this very well. Library files that use multiple applications together have both old and new versions side by side after the library is updated. Applications that were using older versions while the update was running remained the same.If those applications are shut down and started after the update (note - I'm just talking about restarting the application, not the whole system), ...

Firstly we talk about some misconceptions taken on Li-Fi technology - - Many people think that Li-Fi is 100 times faster than WiFi. In fact, I myself have seen this in many places. But in fact it is a misconception. Because, the current technology of WiFi is IEEE 802.11ad which is capable of providing speeds up to 600 Gbps. Which was never found in the Li-Fi  test. So if you think that this technology is 100 times faster than WiFi, then it is a misconception. Another misconception is that if you download a movie using Li-Fi  , it will be downloaded in 1 second or 2 seconds. You see, that's not the point at all. In fact, the speed of the Internet depends on your Internet service provider or ISP and the server from which you download the movie. I don't think there is a server today that is capable of 100 Gbps speeds. However, you can transfer files locally at a speed of 100 Gbps.  Now lastly we talk about the future of Li-Fi technology -- Life is a completely new technology...

 1. When it comes to the benefits of this technology, the first thing to say is its speed. Using this technology you can get speeds up to 100 Gbps. And it has been thoroughly tested. Moreover, the frequency of WiFi is 10,000 times higher than that of WiFi. 2. Since LiFi has a much higher frequency than WiFi, it has the ability to control many users at once. This means that even if the number of users increases, there will be no connection error between them. If we talk about WiFi, you will see that if one user uses more bandwidth, the other user's connection will be slower. But this technology will not be so. 3. WiFi or wireless signals can penetrate your walls. As a result, your neighbors get the signal when you use WiFi. And since LifeFi runs on light technology, the signal is unlikely to go anywhere through the walls of your room. Because we know that light cannot penetrate dense objects. So you will use the internet with this technology at home and no one's father will have...

 Li-Fi full name is Light-Fidelity.  This technology was first discovered by Professor Harald Haas . In 2011, he first published the Li-Fi in front of the people. And he showed how you can communicate with the help of lights. Anyway then he continued to do more detailed research on this technology and he tested this technology about 6 months ago. And test results showed that  Li-Fi was faster than Wi-Fi In fact, this technology is VLC or Visible Light Communication works on ideas. Now what is this VLC, see if you give constant input power to an LED bulb, you will also see its output constant. If you change some of the input power, you will also see a change in the output. The faster you change the input, the faster you see the output change. And with this idea you can create a kind of communication system. You still do not fully understand the matter? Well let me give you more examples. Think of the TV remote this time. In fact, there is an infrared bulb in front of ...

 In order to be proficient in any subject, you need a planned and well-thought-out direction, which by following properly you can build yourself proficient in that subject. Similarly, if you want to establish yourself as a wise data scientist, you also have to move forward in a planned way. And the following steps can be part of this plan. By mastering these you can become one of the best data scientists in the world I hopefully.  Skills development in statistics, machine learning and mathematics : A skilled data scientist is one who has better skills in statistics than software engineers and is more proficient in software engineering than statisticians. That means you have to have a balanced knowledge of both. You don't need to be an expert in either one, but you will get an idea of ​​the basics in both. Machine learning is a little more complex and important in data science. It basically deals with data modeling i.e. data formatting, data type discovery and calculation using...

Simply put, those who work with data theirs are called  Data scientists . The funny thing is that it doesn't take anyone's certificate to be a data scientist. If you have most of the following skills, you too can claim to be a data scientist. However, the demand is not enough, the work must be marked.   1. The most popular property of data  scientists such as :  2. Being able to write SQL queries 3. Messi can clean the data (this Messi is not that Messi) 4. Then be able to prepare that data suitable for running statistical models 5. Scrape data from web pages, PDF files or non-standard places like this 6. Being able to visualize data through graphs 7. Being able to fit machine learning models 8. Being able to do design of experiment and analysis of variance 9. Have a basic and somewhat advanced idea of ​​statistics 10. Being proficient in programming or being able to catch up quickly

  The most famous example is Google. If you search for "cricket" while logging in to Google's service, you will find that if you search for the same keyword without logging in to Google, you will see that the results will be a little different. Have you ever wondered why this happens? The reason is that Google knows a lot about your likes and dislikes. And accordingly he creates a personalized search result for you and presents it to you. Google does this through artificial intelligence which can be said to be a part of data science.Much of what you do, where you go, where you eat, what you shop at, what kind of shopping you do, can now be tracked and is being done. Let's talk about location. The smart phone in your hand is recording everything you do. You may not know or may be aware that Google is collecting this information from you with some additional benefits. Of course, Google has a business purpose and it is also making a lot easier for you.Googl...

 Data science is a field that is new and rapidly gaining popularity. Many people are becoming interested in data science lately. But many of them do not know clearly what is meant by data science. Data science is loosely defined. In other words, data science can mean a lot and a lot is being meant. Depending on which discipline people are using the term, what do they mean by data science. This is because those who work with data can claim to be data scientists. Simply put, data science is a branch where people from different disciplines work together to make data meaningful and usable from which decisions can be made. In other words, the science of using the data in the same way that the data that an organization has will be useful to the organization.  

The keys from F1 to F12 on the top left of the key board are called function keys. The reason they are called functions is because they allow certain tasks (or functions) to be performed. For example - these keys are used to help a program or to run a program. These keys have some special functions in operating system and software. Below is a light thin idea. Keep in mind - the same key may have different functions in software.   F1   For most software, this function acts as a key help menu. If you need help working on a program, you can open the help menu by pressing F1. F2   It can be used to rename (rename) any file and folder. Select any folder and press F2 to rename that folder.   While booting the computer, you can enter the BIOS setup of some motherboards by pressing F2 key.     Moreover, ALT + F2 is very useful for quick command on Ubuntu console.  F3     Press F3 to find any information while working on the computer.  ...

Core I3 processor needs 4gb Ram and Core I5 ​​processor needs 8gb Ram. Because Core I3 to Core I5 ​​processors can perform many tasks simultaneously. So we have to see if it supports 8GB Ram. Again, if the RAM is 8GB and the processor is Core I3, but if it is the pumpkin. Nothing will work. That is, 4gb Ram should be taken in Core I3 processor. And there is no use with more than 4 GB. Because the processor will not support RAM. If the processor does not do the processing, then there is no use with RAM 4 GB, 8 GB or 100 GB. Better to have DDR4 RAM. DDR4 RAM uses very good technology. DDR4 read/write speed is higher.. And this is the most updated version of RAM.

No matter which laptop or desktop you go to buy, you will see that the model number of the processor is given on the monitor. If you see the first letter of the four digits of the model, you can understand which processor it is. About two and a half lakh ICs are used in a processor and there are about two and a half lakh End, Or, Not, Nand gates. 3.3GHZ processor means it makes three crore 30 cell circles per second.

Many processors have U.T.K written on the back. Especially the processor that is written on the back is Ultra Power Saving Processor. These processors are in mobiles. Again you will find HK written on the back of macny processors. Writing this HK means that this processor is a quad core processor and high graphics proessor. They are mainly used in mobiles. The processors you will find written K behind are Unlock Processors. You can increase the speed of Unlock Processors at any time. However, how much you can increase the speed of this K processor depends on your computer's motherboard. The processors that are overclocked processors, i.e. those whose clock speed can be increased, have to use extra cooling system. For overclocking processors, a water cooling system or a large heatsink is required.

If you press ctrl + shift + esc from the keyboard on the Core I3 Dual core processor and go to the device manager, you will see that it is shown as a quad core processor. Due to the presence of hyper threading technology, there are quad cores showing. Hyper-threading technology is a hardware innovation that allows multiple threads to run on each core. Intel Company processors can increase performance and speed by 30% by hyper-threading your cores. Turbo Posting Technology is a frequency boosting technology. If your computer processor is 3.4 GHZ and if this processor has turbo posting technology, it can improve itself to 5.4 GHZ or 4.5 GHZ depending on the work load. It has 2-3 MB cache memory. Intel core I5 ​​processor does not have hyper threading technology but has Turbo Posting Technology. Thanks to which the processor can automatically increase its speed during work. Why is hyper threading technology used in processors? Hyperthreading basically runs multiple threads for each core. ...

The things that we all should keep an eye on are the processor or not; 1. Clock speed 2. Number of course 3. cache memory 4. FBS 1. Clock Speed: It is also called GH2. All processors are written on. Clock speed means how fast your computer can work. That's what this signal means. The speed of the processor is known through this clock speed, how fast the calculation can be done. 2. Number of Cores: The more cores the processor has, the faster the processor can work. If I give an example to explain the matter, I hope you can understand it very easily. Suppose if a person had many hands, then he could do many things at the same time. That is, if we go to the market and buy a smartphone, then we will see what the configurations of the phone are. If we look closely at the configuration of the smartphone, we will see that Dual Core Processor, Quad Core Processor, Octa core processor, Hexa core processor, Deca core processor. This means that the dual core processor has two arms or cores, ...

A device that processes input or output is called a processor. All over the world processor designing companies are: ARM and processor manufacturing companies are: Intel, AMD. Core I3, Core I5, Core I7, Core I9 are all Intel processors, which are very good quality processors in the current market. Processor is one of the most important hardware of the computer without which the computer cannot function. Basically it is called CPU or Central Processing Unit. Actually the microprocessor is a self-contained programmable connecting engine. Which controls and executes all the operations of the computer through the interaction. That is, when we give various commands while running the computer, the processor processes them and gives us output. The devices that we use constantly such as; Laptops, desktops, notebooks, pads, smartphones all have processors. The most popular and reliable processor manufacturing companies are Intel and AMD (Advanced Micro Device).  In our country Intel process...

In today's world I can't think or imagine a moment without technology. We are moving very fast through technology. Since we live in the world of technology and without technology we find it very difficult to get our work done so there should be knowledge about technology in that place and we need to know the details of our technology just as we cannot imagine a single moment without technology. We can easily feel the different directions of our technology Today we are going to get acquainted with some of the technologies that we don't usually know or even if we know that we don't know in full, we only know the short form so we gone to know them through this tutorial today.   IC= Integrated circuit CPU= Central processing unit ALU=Arithmetic Logic Unit  Dos=Disk operating system  IBM=International Business machine  NIC=Network interface card  LSI=Large scale Integration  VLSI=Very Large scale integration  SLSI=Super very large scale integratio...

 Well, think of a day without internet. Well, if you don't have internet one day, then what will you do on that day. What will you do with your wasted time in virtual life? Or will you spend it chatting with friends unnecessarily? Or will you waste time without learning anything alone. It's just me or your story. What would happen to the lives of billions of people in the virtual world besides us if one day the world were without internet? What will happen to millions of Facebook pages? What will happen to millions of Facebook groups? Where will YouTube Silver, Golden Button dream of victory be lost? Where will millions of millions of YouTube + millions of subscriber channels be lost - what will be the importance of those pages, groups, channels today? What would anyone want to do or even if they want to do, what else can they do on that day without internet? If one day there is no internet then thousands of dollars আমেড়ী share market will be threatened.  The New York Stock Ex...

Computers can only understand inferior or machine language. When a program is written in another language, the computer translates it into machine language with the help of a suitable translator (assembler, compiler, interpreter) before executing it. Computer programming language development time is divided into five parts. And this time is called the generation of programming language.In other words, the evolutionary period of a programming language can be divided into five parts depending on the characteristics of the programming language. These parts are called a generation. For example , all the languages ​​discovered from 1945 to 1949 have not been given one. Again, all the languages ​​that were discovered between 1970 and 1979 have been identified by another name.  __________________________________________ At a glance, the computer generations are 6 respectively First Generation --- (1945-1949)  The languages ​​discovered in this generation are:  Machine Language ...

Computers can only understand machine language. When a program is written in another language, the computer translates it into machine language with the help of a suitable translator (assembler, compiler, interpreter) before executing it.   Programming languages ​​are further subdivided into different levels based on program design features: 1. Low Level Language  For example-Machine Language, Assembly  Language. The language of the computer machine is called machine language or mechanical language or inferior language. The basic language of computer is this inferior language or mechanical language (or you can assume first level language: relaxed :). 2. Mid Level Language For example-C, Forth, Dbase, WordStar 3. High Level Language For intance-Fortran, Basic, Pascal, Cobol, C, C ++, Visual Basic, Java, Oracle, Python 4. Very High Level Language- 4GL Like as-SQL, Oracle 5. Natural Language For example-Human language .The language that is closest to the human language (Engl...

It is not very difficult but not impossible for anyone to acquire the same skills as Computer Science and Engineering without studying in Computer Science and Engineering. Let's find out what kind of obstacles you will face. 1. CSE engineering courses are not only taught in CSE. Many ancillary things are taught even outside of CSE. English, Chemistry, Physics, Triple, Accounting, Discrete Mathematics, Other Math Related Subjects, Economics, BBA. In a word, many more are taught than just programming. If you are not a CSE student, you may not be able to master these things. You may not read these related things in the subject you are going to study. 2. In the case of CSE Engineering, new languages ​​will be taught every semester. Experienced teachers never teach a new language A to Z. They teach the basics and highlight the main topics in each language. If you are out of CSE, you will not get the guidelines of these experienced sirs. 3. The biggest advantage of CSE engineers is compe...

   1. The purpose of using a VPN is to allow you to securely exchange your information. 2. No one will be able to track your location using VPN. 3. You can hide the IP address (Internet Protocol address). That is, hackers are less likely to get caught. 4. Get full speed net from your internet service provider IPS. 5. With VPN you can visit blocked sites in ISP / IIG / Country. For example, if Facebook is blocked in our country, you can still access Facebook using a VPN. 6. VPN can also be used for many official purposes. Doing a lot of important work with VPN can protect against hacker attacks. For example, if you are working on a banking server at home, it is very important to use a VPN, otherwise hackers can take information from your server.

   Currently there is no shortage of free VPN software and to get most of the VPN services you have to open an account on those VPN websites. After that you have to download and install the registered software. Again some VPNs like Microsoft There is no need to open an account in Touch VPN in the web store. All you have to do is install and connect the app from the App Store.   However, this free VPN software does not have servers in all countries. Also some VPNs may force you to use paid services after using a certain amount of bandwidth. The advantage of premium VPNs is that their connection process is more secure and in this case paid VPNs are able to give you maximum amount of internet security. In addition, paid VPNs can connect to servers in almost all countries and premium VPNs are less likely to lose data.

   We are all somewhat familiar with the term VPN. However, we all know this name, but very few of us know about it. Today we will briefly discuss what VPN is, what it does and why VPN is needed. What is a VPN? The full form of VPN is Virtual Private Network. Simply put, a VPN is a fictitious ‘tunnel / channel’ through which information can be exchanged securely / secretly. This ‘tunnel / channel’ or tunnel does not exist in reality, it basically means a fictional / virtual private network through which information can be exchanged securely on the internet.   The Internet is a place of open information exchange. Suppose you are playing football in an open field, where many others like you are playing, your ball may go in the middle of their game and their ball may come in the middle of your game, so that anyone can kick that ball. Again, those who play with the entire field, no one else can get in the middle of the game. In the same way, since the Internet is a p...

  When a computer, laptop or mobile is connected to a VPN, the device connects to the VPN server and creates a virtual network that is only for your device. This is why it is called a virtual private network. All your internet traffic such as browsing, downloading, server connection will all become the server connected to the VPN.   In this case, VPN is able to do such a thing that you will feel the Internet from USA, you are in the country of VPN connected server. In this way, by going to the public WiFi zone, you can keep your browsing safe, and you can use services like Hulu, Spotify sitting in the country. Because when you are VPN connected, your computer will go through any website with encrypted VPN connection. In this case VPN acts as a secure connection between your computer and the website you will connect with. So with hidden VPN easy to use blocked website and service by hiding Global Positioning System location.

   The full e; regi of AM is Ante meridiem. AM means before or before and meridiem means noon or longitude. In this case Ante meridiem means any of the middle subjects. That is, Ante meridiem means time from 12 noon to midnight or from 12 noon. PM's full e; regi is post meridiem. PM means after and post meridiem means noon or longitude. In this case meridiem means any of the middle subjects. That is, post meridiem refers to the time from 12 noon to midnight or 12 noon. What is the secret of AM and PM?     Time is a name very familiar to us. At the present time we see AM and PM by time in wrist watches, mobiles, wall clocks and computer time displays. What do these two mean to us? What is the secret of AM and PM? The term PM is used after the time to mean 12 noon. And AM is used after 12 o'clock at night. In other words, AM has to be said from 12 noon to 11:59 am the next day. And from 12 noon to 11:59 pm that day.   The English word for AM is Ante me...
