This document discusses the evolution of technology from analog to digital, wired to wireless networks, and the corresponding security challenges. It covers the transition from analog to digital television and modems, how wired and wireless networks connect communication points, and common wired and wireless communication media like twisted pair cable, coaxial cable, fiber optic cable, infrared, radio broadcasts, cellular networks, and satellites. The document concludes that while these avenues have improved connectivity, cyberthreats from hackers require ongoing safeguards as technology rapidly advances.

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.

9. 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.

10. 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

11. Cyberthreats, Hackers, &
Safeguards

12. 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.
