Chapter 2 Introduction to Networking Exercise 2.1.1 The 5 foundations of networking are necessary for allowing one device to communicate with another‚ because without any one of those five pieces of foundation‚ the communication wouldn’t work. Without the media‚ you wouldn’t be able to connect to anything‚ since media is your signal. Without an interface you wouldn’t be able to access any information on your computer. If you didn’t have a signal‚ you wouldn’t be able to transmit any information

“old-school” watches (Moran & Vallejo‚ 2013). Amongst the main products is the Samsung Galaxy Gear‚ which allows integration of the wearable watch with a number of devices extending the traditional power of a watch into a control center. With the advent of newer technology on such frequent basis‚ we tend to forego the social impact that these devices have on its users. The question of ethics will be brought up‚ how far engineers are willing to go into this technology‚ will they stop with integration with

Computers have become such indispensable devices in the modern era that we cannot imagine life without computers. However‚ there have been different ideas on the benefits of computers. In my opinion‚ computers do more good than harm because they can make life easier and also can help our work become more systematically and productively. Firstly‚ computers give many advantages as they can make life easier. As a student‚ many works must be done by using computer such as assignment and presentation
