How was the telephone used?

The first telephone was made with the knowledge that sound gave off waves due to vibrations, like the ripples in water. These sound waves were copied over onto carbon grains, which an electric current traveled through to make the grains vibrate. However, the different patterns of the grains altered the resistance of the grains against the electric flow. In this way the sound made more or less current flow in the circuit. These currents were in proportion to the sound waves that first entered. At the other end was a coil of wire within a magnet attached to a diaphragm. The variations in current caused the wire to move in the magnetic field. These vibrations move air, and that reproduced the sound at the other end!

Answer

What is the difference between twisted pair and coax?

Twisted pair wires have twists that are a certain number of twists per foot depending on twisted bundle size. The purpose of the twists is so the magnetic field that rises and collapses around each wire within the twisted pair cancel each other out since they are of opposite polarity.

The coaxial cable is just a single conductor within a grounded braid or foil jacket to help prevent unwanted magnetic fields (signals) from entering the actual signal wire that is in the center.

What is bad things about technology?

Developing technology is a skillful art. It takes time, persistence, and a new skill set of knowledge that not many educational facilities are teaching properly. Many times, I want to simply pull my hair out when technology and software goes offline and has bugs in it. The cons of technology are:

Although our productivity has seemingly dramatically increased, we have become reliant on on technology to accomplish certain tasks. Do you remember your friend's phone numbers anymore? The fact the about 22% of our time spend online is on social media sites - is also cause for alarm. Not to mention the hundreds of time-sucking technology games that is available for free all over the web.

Many times jobs that previously required actual living humans to run can now be automated by the use of technology, further reducing jobs and causing an increase in layoffs.

At times, I don't want to have instant access to my email. At times, you may not want your employer to be able to get in touch with you. You may not want your GPS to always know where you are. I have met multiple people who have had their relationships ruined by Facebook. People posting pictures of things they were not supposed to be doing can get you in to trouble. Employers check Facebook profiles, view pictures, and have the ability to discover all sorts of secrets about your personal life.

With the ubiquitous availability of the Internet, we're now taking on the role of gathering and assessing this information ourselves, often before we visit or return to our doctors.
