Abstract
Wireless sensor networks are a budding technology with the potential to change the way that we live. This report explains the workings of each network as a system of tiny computers called motes and the parts of the network. Furthermore, this report goes on to explain the parts of each mote, including a portion on MEMS technology to show the development of motes.

    In 1969, the first message, “login”, was sent over ARPANET, the predecessor of today’s internet (Kleinrock, 2008). ARPANET was designed as a communication system that would allow researchers to access information from other researcher’s computers around the country, therefore allowing information to flow more freely (Kleinrock, 2008). Computers and the internet have become intertwined into our daily lives.…

Because the video were discussing clearly, systematically, and easily the cycle of information we are working within a computer network. The characters involved on that movie are the data circulating inside a network which are the TCP packet, ICMP ping packet, UDP packet, router, ping of death, router switch, network routes , firewall and of course the net and they are being animated so that the video clip turns the whole discussion more visible to me.…

    Over the past forty years computer networks have dramatically changed the way that we work, play, and communicate. In more ways than ever thought possible, we now have information and personal communication literally at our fingertips. The technology has become so evolved and integrated into every area of our lives that most people are not even aware of their lifestyle's significant reliance on computer networks. Television, cellular and landline phones, the Internet, our national military forces, and even the electricity received through the walls of homes would all fail if computer network technology was to vanish from the earth. This document will cover the history, workings, and modern day implementations of computer networks and the most common data communication protocols they utilize.…
