  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        >    vi...

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 e...

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...
