How people use them, what kind of information we give away, what companies will do with this. Information sharing and data protection has become very popular theme in the recent few years.

When wrongly access this kind of data, a lot damage could be done by criminals. Users privacy settings should be reviewd and fixed when needed. Social media Humans hav
How does virtual communication influence our behaviour and relationships? Virtual world is growing closer to ours every day. It has its pros, as well as cons and the industry involved in it has grown most rapidly in the last 15 year. Therefore, does virtual communication influence us positively or negatively? Becoming virtual in the means of communication has changed our lives forever. Recent studies tell that about 75% of the people in North-America use the internet and from that 95% use email and other virtual communication software. This percentage has grown over 130% from the year 2000. I bring my examples on North-America because there is the highest percentage of Internet users in population. Talking of it, what is internet? Statistics say that it is porn, but I believe that people mostly use it for communication. But can it be bad?

OSI Model Internet packets, or Internet datagrams An Internet protocol packet, or datagram, is a morcel of information that is sent out on the net. For example if you send an email to someone, then your computer will break that email message down into small peices and "encapsulate" them into packets with some destination address. This encapsulation means that your message, or more likely a small part of your message, will be put inside of an Internet packet. IPV4 datagram Governance The Internet is a globally distributed network comprising many voluntarily interconnected autonomous networks. It operates without a central governing body. However, to maintain interoperability, all technical and policy aspects of the underlying core infrastructure and the principal
Mass Media What is Mass Media? Statistics show that there are few things which impact the human mind more than mass media. The advice of teachers, parents and relatives may fall on deaf ears, but the mass media influence holds us all spellbound! At this point, it becomes necessary to define mass media. Mass media may be defined as any form of communication which is meted out to the people at large, through the various forms of communication. What modes of communication are we talking about? Well there can be no static definition for the channels of mass communication as they are increasing all the time.

Mass media holds a kind of mystique in the minds of the people. It is because the communication is designed in such a way
