1. NETWORKS, & SAFEGUARDS THE WIRED & WIRELESS WORLD Douglas C. Pippen American Military University 2. Introduction Growth is suppose to happen over time and gradually, but for technology the last few years it has taken off. Going from Analog to digital, and going from wired to wireless. Also the security has evolved, but so has the threats. With so many changes and so fast one must remain current on all technology updates and threats. 3. Analog to Digital When thinking about Analog to Digital, all you have to do is look at your TV set. 4. This tech jump has been more notable because everyone has a TV. 5. Modem I see a modem as a bridge that connects to highways, but you have to pay the toll to use it. 6. A modem is a combined device for modulation and demodulation, for example, between the digital data of a computer and the analog signal of a telephone line. 7. Networks A series of points interconnected by communication paths. 8. Wired Communication There are 3 types of wired communication media. Twisted, Coaxial, and Fiber-optic cable. Even though these wires are different and do different things. They play an integrate role in networking and bringing communication together. I have version fios and I have all 3 wires in use right now. 9. Wireless Communication Media Wireless communication is thought of as cell phones and laptops, but wireless communication is known as: Infrared transmission Broadcast Radio Cellular Radio Microwave Radio Communications Satellites 10. Cyberthreats, Hackers, & Safeguards 11. Conclusion Here we have covered Analog to Digital, how networks work, wired communication media, wireless communications media, and cyberthreats, hackers, and safeguards. All of these things have one thing in common. They are all communication avenues that we use everyday. Rather it be business or personal. 12.
