There are mostly two kind of interface we discuss, when it comes to Operating systems. Initially, when computer were came in the market, there was only one, it was Application Programming Interface which is also referred as API. This definition I got on Google  :-            "API, an abbreviation of application program interface, is a set of routines, protocols, and tools for building software applications. The API specifies how software components should interact and APIs are used when programming graphical user interface (GUI) components."    IF you have used old model windows or unix then you would probably know how frustrating it was to use non-graphical applications. While we use API this help us creating a Graphical interaction with users. So people would know that this a media file and this is a text file. This made computer very easy to use without even knowing how to program a computer or how to give commands. We actually design a layer of upper thing, obvio

When we use operating system, we operate it with two kind of memory, or in technical way you can say that Operating system operate its application in two ways. One via physically and other opposite virtually. Physical memory used for storing the information. It works as a task. But the process to execute this task has been done by virtual memory. Our operating system creates a virtual operating system while we use any application, it access the data we provide it,  and if we allow it , then it save it on physical memory. Using this techniqe secures our Hard disk from getting corrupt. Difference Between Task and process is that process is a dynamic entity. When we execute any work it start processing and when it finish the work and convert it into a product or value then we can say task has been complete. Task is a container of processes. So in our real life I have seen so many things like that, like if I talk about our future, then go back 100 years ago. In the beginning of 20th

Guys ,       I was studying a book named accidental billioners and found how Zuckerberg sir had hacked university sites and found the whole data. But the problem he found that it was very large data how he will be able to find all the images at one place. Then he thought of an python script. He wrote and execute it then he found all the JPEG, PNG or other image files at one place. I dont know in details how he did that. But I have a python script that shows you all your files in particular directory and with particular extension. here it is.   import glob, oss for root, dirs, files in os.walk("E:\\"):     for file in files:         if file.endswith(".txt"):              print(os.path.join(root, file)) Save this file on notepad by putting dot ".py"extension. For testing-  1- Obviously you will need python which you can download from-  Python org 2- You need to store path variable if you are using windows.  3- Then You'll need to st

Finally our dream came to an end, when plane landed on the airport. We went outside and found a man who was expecting us. We shook handed, we gave him our Intro, and Finally he took us in his car. America really is an amazing place to see, when I was watching it from the sky, it seemed like we are in some different world. A world that is filled of dreams and opportunities. A world which has everything that we need to be happy, or we need to achieve. Swatantra and Prince were also astonished by the vision. We didn't talk much during our journey, we were quite from outside, and cheering loudly from inside. This was the place, time , opportunity or whatever people call dream, we were waiting for.               We reached to a hotel named ,'Best California suite'. I don't exactly remember the name. But the hotel was amazing. And we get into room. The employee left us there and leaved. I started searching for google places. I found the headquarter of google is in Californi

I am a beginner in learning about operating system or how it works. So in a book I found a definition of it, and it was very different, it was- An Operating System provides the basic functionality, look, and feel, for a computer. The primary purpose is to create a workable Operating Environment for the user. Yeah right not so different, but look and feel seem human applications. I wanted to understand operating system perfectly. I didn’t yet though but still I compared it to our brain system. And I found some identical application that our brain and OS both do. May be I am overexcited or overtired of reading an OS book. More than nine hundred pages, you can’t read all of them without adding some fun in it. I like science because it’s all about generalizing things, so I compared two of the science streams to get some knowledge or fun you can say that. Anyway, let’s start with your brain. Application of Human Brain-  An operating system also has a min

Our inspiration and motivation are the tools which we use against darkness of despair. It works like a torch and shows us appropriate path to walk. Every human being or living creature I should say, they know how to find the torch in darkness. This darkness reminds me of my Nani’s room. She lives in village, and often when electricity comes it becomes news. And a day when electricity gone, I found that it was hard to see anything in that darkness. But my Nani who supposed to wait for someone to fetch torch for her, she couldn’t even see properly in daylight, she got up and found the torch for us. I noticed it first time, and then I asked Nani how did she do that? She replied, “It becomes easy when you become used to of your problems.” And now I can infer you that life is all about getting used to of your problems. Bill gates has said, “Life is always unfair, get used to.” And by getting used to, you began to find your own solutions. Our Inspiration and motivation are also part of our

India is a democratic country. Everyone has right to criticize anyone. Everyone has right to be cynical, so that they can blame anybody for anything. I am not saying that being democratic is wrong. But being a cynical democratic is something that prevent us from utilize our skills and development. My main gesture is towards our government. Our government ran by us more than the government people. They treat us as we want to be treated. For instance, we people criticize our government on many issues. That’s good; it shapes our government in right way but sometimes some politician or a politician party takes it for granted, especially those who are not in center. They want us to be cynical for the ruling party. Sometimes it helps and fetches some nice results, but most of times it just brings chaos. Our government becomes more focus on defending themselves instead of acting on the problem. I would also say that it good to criticize them on certain issues. But that issue should not lea
