Answer: Electronic media can only be seen by the use of electronics(computers, laptops, iPads, iPhones, Kindles, video games,television, etc.). Print media is words and images printed on paper(newspapers, magazines, books, etc.).
Answer: Many ways to do this. One way (the way i am doing it) is connecting a WDTV Live to my TV. WDTV Live can connect to my network harddisk (or a simple USB, external harddrive) where i have stored all my moviefiles, music and pictures. Chances are you already have an external harddrive of some sort. So i think WDTV/WDTV Live is a cheap option.
Answer: I think that web media is slowly replacing print media. I say that as a print media hold-out. While newspaper is certainly on the way out, I was still skeptical about the prospect that books and magazines would be replaced. Now with the advent of reasonable working ebook readers like the Kindle and Nook, books and magazines are going to see their print versions take a hit. So the answer to your question is: Yes - print will eventually be replaced by web and digital media.
Answer: Controlled-based media access control is based upon having a system in place for allowing one host to transmit at a time. It is also known as deterministic method since there is a process to determine which host transmits at a certain time. No collisions exist with this type of media access control. An example would be token ring where a token is passed from host to host and when it has the token it can transmit and others do not transmit at that time. Contention-based media access control is known as non-deterministic because hosts can transmit whenever they want. CSMA/CD is an example of this. Collisions do exist.
Answer: No one. As long as there are people and guns, there will be gun violence. Always. All that can be done is that action can be taken to mitigate the effects of people having guns. There are ideas around (that have been around a looooong time) that include restrictions on gun ownership, harsh penalties for possession, even more harsh for possession during a crime (enhancements), and a swift and sure execution for those who commit murder with a gun. Nothing new here.
Answer: Niche media is known as narrowcasting and it is information aimed at a narrow audience such as an ad addressed towards teens and children. Mass media is information addressed to a large number of people in a short period of time. Addressable media is information delivered to people of a certain address location.
Answer: First off, get some music relating to the topic. For example, if one was doing a PowerPoint on say, Papua New Guinea, then one would use music that sounds like a tribal drum beat. one could also use video to help the audiencesee the point of your presentation. That and a guest speaker will get the audience ready to learn.
