INTERNET AND COMMUNICATION Part 1

THE HISTORY OF INTERNET AND COMMUNICATION

The history of the Internet began with the ARPANET and connected mainframe computers on dedicated connections. The second stage involved adding desktop PCs which connected through telephone wires. The third stage was adding wireless connections to laptop computers. And currently the Internet is evolving to allow mobile phone Internet connectivity ubiquitously using cellular networks.

The history of communication dates back to the earliest signs of life. Communication can range from very subtle processes of exchange, to full conversations and mass communication. Human communication was revolutionized with speech about 200,000 years ago. Symbols were developed about 30,000 years ago, and writing about 7,000. On a much shorter scale, there have been major developments in the field of telecommunication in the past few centuries.

Communication

Communication is the most popular use of the Internet, with email topping the list of all the technologies used. Some of the types of communication technologies used also include email discussion groups, Usenet news, chat groups, and IRC. These are unique to networked computer environments and have come into wide popularity because of the Internet. Other technologies, including video and audio conferencing and Internet telephony, are also available on the Internet. They require more multimedia capabilities of computer systems and are more taxing of network resources than the others. They also are adaptations of other technologies to the Internet.

When you’re communicating on the Internet take special care not to give out personal information to strangers and to treat others with respect. Be aware of the risks involved in communicating with people you cannot see and may never meet in person. Take time to consider what you write to others, and be careful to avoid humor and sarcasm except with the best of friends. You can’t assume that your messages are private, so be careful about what you write.

Several issues related to ethical and legal considerations arise from using the Internet for communication. The manner in which communication is implemented on the Internet makes it susceptible to monitoring. You can’t assume that communications are private. Some believe that sending email is like sending a message on a postcard. Some laws have been enacted to help protect privacy during electronic communications. These, however, have been difficult to enforce and are rarely applied. One way to protect privacy is to encrypt or code a message. A common way of encrypting messages is through the use of public and private keys. Although software for encryption is readily available, current policies and laws prohibit its export.

Another area of concern is dealing with abusive or offensive communications. Laws that apply to libel, harassment, and abuse have been applied to cases where the offending behavior has occurred on the Internet. Unsolicited email or other forms of communication is called spam. It definitely is an annoyance, but also quite costly to the people who receive the junk email or other communications. It’s relatively inexpensive to produce, because most of the cost of transporting the email is shifted to the receiver and all people that use the networks supporting the Internet.
