| Answer» <p>b) The history of the Internet begins with the development of electronic computers in the 1950s. </p><p>Initial concepts of wide area networking originated in several computer science laboratories in the United States, United Kingdom, and France.</p><p>The US Department of Defense awarded contracts as early as the 1960s, including for the development of the ARPANET project, directed by Robert Taylor and managed by Lawrence Roberts. </p><p>The first message was sent over the ARPANET in 1969 from computer science Professor Leonard Kleinrock's laboratory at University of California, Los Angeles (UCLA) to the second network node at Stanford Research Institute (SRI).</p> <p>a) Advantages:1) Electronic Communications:Before the Internet came into existence, to communicate with someone who isn’t in the same room as you, you would have to call them on a phone. Or if you wanted to send them a note you had to send a letter through snail mail. With the introduction of the Internet, we now have the ability to send and receive messages through electronic mail- virtually instantaneously and without the need of a postage stamp.</p><p>2)Online Shopping:With the Internet came the convenience of online shopping. Rather than having to drive to a mall and wait in long lines to make a purchase, you can now do all of your shopping with a few clicks of the mouse. In addition, the Internet made it easier for individuals to price compare between different online retailers to see which one offers the best selections and prices.</p><p>3) Online Banking:Nowadays, online banking is practically the norm. You log into your online accounts to pay bills, transfer funds, or just to check your balance. Prior to online banking, you would have to drive to your local bank and wait in line for the next teller to have your transactions completed. With the Internet, you can avoid the line all together simply by remotely logging into your account on your computer and completing your transaction from there any time of day or night.</p><p>4)The Internet of Things (IoT)The main advantage of the Internet is its ability to connect billions of computers and devices to each other. Not only does the Internet create convenience in sharing and receiving information between users, but another advantage of the modern Internet is also its ability for automation. Enter “The Internet of Things”, where devices and sensors communicate with each other to automatically perform a designated task or function. For example, a smart thermostat could reduce your energy cost by automatically adjusting the temperature when it senses you have left the house. Additionally, it “learns” your heating and cooling preferences and adjusts them to your liking.</p> <p>d) HyperText Information System.Cross-Platform.Distributed.
