  Concepts of  Virus & Worms ( Ethical Hacking )              👷  Posted By  Souvik Kumar Parui Introduction to Virus : Computer viruses have the potential to wreak havoc on both business and personal computer. Worldwide , most businesses have been infected at some point . A virus is a self replicating program that produces its own code by attaching copies of it into other executable codes. This virus operate without the knowledge of desire of the user .Like a real virus, a computer virus is contagious and can contaminate other files.  However virus can infect outside masons only with the assistance of computer users .Some virus affect computers as soon as their code is executed ; other viruses life dormant until a pre-determined logical circumstances it met . There are three categories of malicious programs ::        >    Trojans and rootkits        >    virus        >     Worms Worms is a malicious program that can infect both local and remote machines .

 Basic Concepts of Reversible Circuits ( Quantum Computing )                           - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -                        👷 Posted By Souvik Kumar Parui              Introduction : In recent years, the research community has shown considerable intentness towards the reversible logic due to its potential to minimize the power dissipation in the VLSI circuits to design a power efficient circuit. The reversible logic holds the key feature of designing the information lossless circuits and it may lead to zero-energy dissipation in the ideal case.     Reversible Logic :                      A function is called reversible if it has equal numbers of inputs and outputs and there exists a bijective mapping between them.  Reversible functions are used to implement the reversible circuits.      Example  :  Let us consider a function (x1, y1) → (x1, x1 ⊕ y1) is said to be a reversible function as the function has two

1. HTML Image Tag:    HTML <img /> tag is insert image into a web document.  HTML image path define/declare inside <img /> tag.  The <img /> tag is empty tag, that mean's no closing tag.  <img /> tag have some attributes are use for display image on web page.  The src attribute, src stands for "source", that is path of image URL  Alt Attribute used to define an "alternate text" for an image. This specifies text to be identified in the image name.  Width and Height specifies the size of image to display on webpage. Example : Image alignment (Right side) : <html> <head>  </head> <body>   <img src="images\img_nat.png" width="120" height="80" alt="Natural" align="right"/>   <p>Natural resources (economically referred to as land or raw materials) </p> </body>  </html> Image alignment (Wrap around):  <html

Building Your First Web Page : ##lesson1

Image
Lesson 1 Building Your First Web Page If you can, imagine a time before the invention of the Internet. Websites didn’t exist, and books, printed on paper and tightly bound, were your primary source of information. It took a considerable amount of effort—and reading—to track down the exact piece of information you were after. Today you can open a web browser, jump over to your search engine of choice, and search away. Any bit of imaginable information rests at your fingertips. And chances are someone somewhere has built a website with your exact search in mind. Within this book I’m going to show you how to build your own websites using the two most dominant computer languages—HTML and CSS. Before we begin our journey to learn how to build websites with HTML and CSS, it is important to understand the differences between the two languages, the syntax of each language, and some common terminology.  What Are HTML & CSS? HTML , HyperText Markup Langua
