Week 6- EOTO

The technology I chose to research is Bluetooth. Bluetooth is a type of technology that allows you to connect one device to another in order to share data. Bluetooth originated at the Swedish telecommunications company, Ericsson. Nils Rydbeck and Johan Ullman comissioned Jaap Haartson and Sven Mattisson to come up with short link radio technology. The goal was to not have as many cables between different technologies.

Bluetooth is not tied or linked to any product but instead managed by the Bluetooth Special Interest Group. They are a committee who revises standards and licenses technology and trademarks to manufacturers. Bluetooth is advanced enough that you can connect to multiple devices from one device. For example, my iPhone allows me to be able to Bluetooth my car, speaker, headphones, friend's car, my printer, and much more. However, once a device is conncted you cannot connect to another at the same time.

When people think of Bluetooth, they likely think of cars. New car models have Bluetooth so that drivers can make hands-free calls and listen to music without having to have their phone plugged into the AUX or charging cord. By using Bluetooth instead of holding the phone in their hand, drivers can be safer and keep both hands on the wheel. Most cars allow for you to change songs, pick up/hang up the phone, and change the volume with controls on the steering wheel. If a car is older and doesn't have Bluetooth, there are devices you can buy. An example of one is a FM transmitter. You can plug them into the charging port of your car and set the device to a radio station. You then change your FM station to the same radio station. The transmitter allows you to Bluetooth connect your phone, and then the music and calls will play over the stereo. I have one, and I find it very helpful. They are also inexpensive! Bluetooth can also be used to connect your phone to a speaker or wireless headphones. Unfortunately, Bluetooth does not have that large of a range and generally only works from about up to 30 feet. Bluetooth is also used in less noticable ways, like to link a printer, mouse, or keyboard to a PC. It can also be used to link smart watches to your phone or tablet.

Overall, Bluetooth is an underrated but extemely helpful technology you likely use in your day-to-day life, even if you don't realize it. As technology advances, I look forward to seeing how Bluetooth improves and grows to become even more helpful.

Week 12- Diffusion Theory

Social media is taking over more and more as society and technology advances. Looking at social media through the Diffusion Theory lens allows us to have a different perspective on WHY it caught on and how. Some people were early adopters and were open to joining social media sites when they began. Some people, however, were not on board and avoid social media and all it has to offer. There are many reasons why someone might enjoy and catch on to social media. If they like being able to communicate with others when they are not together, share ideas and likes, and see what other people are doing in their day-to-day life, someone would enjoy social media. The early adopters are ones who are morer well-versed in the 'do's' and 'dont's' of different socials. For example, an early adopter of Instagram would have a better understanding of the platform and what posts are most popular than someone who was a late adopter. It also is an easier option for those with soc...

Week 5- Antiwar Voices

When watching, listening, or reading the news it is not often that we hear about strong anti war agendas. This may be for a number of reasons, but I believe it is because most Americans think that war corresponds with strength, and everyone wants to belive they live in a strong country. Lots of companies also profit off of war, and want to promote wars so they continue to make profit. Another reason could be that American wants to tell its citizens that war is good and worth the money, resources, and lives. If the media was constantly promoting anti-war agendas, the morale of the general public would decrease and the government would have to deal with people arguing war and protesting it. I think that people have to seek out these obscure websites to read about this topic because the media and government do not want people hearing about it. In America, people who are antiwar are typically a minority, and their writings do not get as much traffic as they shoud. I think that everyone s...
