Virus - Since when

Image
Since when are viruses being spread through the internet? The first major attack was in 1999 when American, David L Smith, designed the Melissa virus (named after exotic dancer) that could spread through email. It required a host to run proper, which in this case word document attached to an email. . Once opened, the virus replicated and sent itself to 50 people in the email address book. the increased email traffic because of thousands of infected computers forced some companies to shut down email.

Viruses - Malevolent for everyone

What is a computer virus?In 1949, when computing was just about a decade old, Hungarian-American scientist John von Nuemann theorised the possiblity of writing a self-replicating program, which later came to be known as a computer virus. These programmes,  which need a host to function, are designed to make unauthorised and undesirable modifications in infected computers. Initially, viruses were designed and tested in university computer labs. The first virus that went 'inthe wild' - outside the lab/computer in which it was designed - was Elk Cloner which was written by Richard Skernta, a school student in the US.Viruses written during the period were spread through floppy disks and hence caused a major security threats.

Social Media

Social Media - a welfare for people
Our Prime Minister, Mr Narendra Modi, urged bureaucrats to use social media for the welfare of the people. Social Media sites are very helpful when they are used for spreading information about the good work being done in a locality. Take the case of vaccination programmes. It gets a boost   via sites like Facebook, Instagram, Twitter and others.
So think beyond 'Selfies!', 'Share and Inform' your virtual world circle about relevant events taking place around you - it could be a cleanliness drive in a city. Talking about spreading information, social media can be used as a platform for building public opinion for various social issues.
