What are the number systems in Computer? Number systems  are the technique to represent numbers in the computer system architecture, every value that you are saving or getting into/from computer memory has a defined number system. Computer architecture supports following number systems. Binary number system Octal number system Decimal number system Hexadecimal (hex) number system 1) Binary Number System A Binary number system has only two digits that are  0 and 1 . Every number (value) represents with 0 and 1 in this number system. The base of binary number system is 2, because it has only two digits. 2) Octal number system Octal number system has only eight (8) digits from  0 to 7 . Every number (value) represents with 0,1,2,3,4,5,6 and 7 in this number system. The base of octal number system is 8, because it has only 8 digits. 3) Decimal number system Decimal number system has only ten (10) digits from  0 to 9 . Every number (value) represents with 0,1,2,3,4,5,6, 7,8 and 9 in this nu

What is an operating system? An  operating system  is the  most important software  that runs on a computer. It manages the computer's  memory  and  processes , as well as all of its  software  and  hardware . It also allows you to  communicate  with the computer without knowing how to speak the computer's language.  Without an operating system, a computer is useless . The operating system's job Your computer's  operating system  ( OS ) manages all of the  software  and  hardware  on the computer. Most of the time, there are several different computer programs running at the same time, and they all need to access your computer's  central processing unit (CPU) ,  memory , and  storage . The operating system coordinates all of this to make sure each program gets what it needs. Types of operating systems Operating systems usually come  pre-loaded  on any computer you buy. Most people use the operating system that comes with their computer, but it's possib

Bridge to Terabithia centers around fifth grader Jesse (Jess) Aarons, an artistic but poor boy living on this family’s farm with his parents and four sisters. The book opens with Jess training to become his classroom’s fastest runner. However,  Leslie Burke , a new girl who earns the approval of teachers, ends up winning the race. Jess’s initial dislike of Leslie for this reason soon disappears, though, as Leslie’s intelligence and individuality bring out his fondness for her, and the two become fast friends. Jess and Leslie swing over a creek on a rope and decide to call the land beyond Terabithia. The two of them become Terabithia’s king and queen, build themselves a castle, and use their new land as a refuge from life at school. Leslie, more well read than Jess, teaches him the appropriate words and behaviors of a king, and lends him a set of C.S. Lewis’s Narnia books to read. When Jess brings Leslie a puppy for Christmas, the two name him Prince Terrien and make him guardian of Te

CAREER IN  CODING  Most people, who want to start coding, don’t know how and where to start. Most of the time they even don’t know, which programming language to learn first. Right now I have experiences in HTML, CSS, PHP, JAVA, C++, Python and R. In this story I will tell you how I started. How it begun Nearly two years ago one of my teachers asked me to join the schools homepage-team. The purpose of the team was to administrate (and also develop) the  schools homepage . At this time there was only one programmer, who really code something. The others added articles to our homepage, so they didn’t need any programming skills. At this point I have to admit that I had no programming skills as well. Because our ‘senior’ programmer hadn’t really time, I had to learn everything from scratch on my own — quite hard and the same situation many readers of this story might be in as well. Web Development I was so excited and so started a research in the web on ‘how to learn web development’. I k

          हम अगर यह सोचें कि हमारे किसी काम में रुकावट न आए, तो ऐसा नहीं हो सकता है। दुनिया में ऐसा कोई नहीं है, जिसके किसी काम में कभी बाधा नहीं आई हो। इसलिए बाधाओं से डरकर अगर किसी काम को अधूरा छोड़ दिया तो फिर आप जीवन में कभी सफल नहीं हो पाओगे। कभी अगर जीवन में सफल हो भी गए, तो लंबे समय तक उस सफलता को बरकरार नहीं कर पाओगे। यही बात हमारी आज की इस कहानी में भी बताई गई है।             अमावस्या का दिन था। एक व्यक्ति उसी दिन समुद्र-स्नान करने के लिए गया। मगर वह समुद्र में नहाने के स्थान पर किनारे बैठा रहा। उसे इस तरह बैठा हुआ देखकर किसी ने उससे पूछा, स्नान करने आए हो तो किनारे पर ही क्यों बैठे हो? स्नान कब करोगे?           उस व्यक्ति ने कहा, इसी समय समुद्र अशान्त है। उसमें ऊंची-ऊंची लहरे उठ रही हैं, जब लहरें बंद होगी और जब उपयुक्त समय आएगा तब मैं स्नान कर लूंगा। पूछने वाले को हंसी आ गई। वह बोला, भले आदमी! समुद्र की लहरे क्या कभी किसी के लिए रुकती हैं? ये तो आती-जाती रहती हैं। समुद्र में स्नान तो लहरों के थपेड़े सहकर ही करना पड़ता है। नहीं तो स्नान कभी नहीं हो सकता।           यह हम सभी की ब

Web Applications (Basics) Introduction A Web application refers to an application, which can be accessed through a Web browser, such as Internet Explorer or Mozilla Firefox. Web applications are those applications that are only accessible using Internet. Web applications came into existence to overcome the shortcomings of desktop applications which can be hosted on all the computers but not on the network or Internet. Web applications are generally hosted in client-server networking environment. The Web applications also help the companies in reaching out to prospective clients and conducting businesses online. Networking Fundamentals The term ‘networking’ represents the processes involved in developing, designing, implementing, managing and upgrading network technologies. A network generally consists of two or more computers which are interconnected either logically or physically using special software and hardware. Networked computers exchange information and share
