The Internet and Bluetooth

     The internet is a global system of computer networks that allow data sharing and communication within people. The internet was founded by many people in the 1950's and 60's. Tim Berners-Lee is known as the creator of the world wide web. Marc Andreessen is the creator of the first widely used browser in the world called mosaic. The internet was created for scientists to share data securely and for the Cold War security. At first, the internet was only used for military, academic, and government researchers, no one else in the world got to use it. Today, it is used for universal communication, online banking, shopping, news articles, and much more. 

    The creator of the world-wide web is Tim Berners-Lee. He created it for in 1989 to help scientists communicate with each other and share ideas. The world-wide web was originally used to navigate information using hyperlinks. It is now used for social media like instagram, twitter, snapchat and facebook. Another use for it is streaming and e-commerce. 

    The internet and the world wide web are not the same thing. The internet links your computer to many computers around the world creating a communication between people. The internet is mostly used for emails and transporting files. The web is the pages you see while you are on your computer. For example, like watching streaming services.      

    The first website created was by Tim Berners-Lee. It was posted on April 6, 1991. The purpose of it was to explain how to use the world-wide web in general. Specifically, how to hyperlink and how to create web pages. Yes, the website is still up. The url is: http://info.cern.ch/hypertext/WWW/TheProject.html. 

     A URL is the address that is typed into the browser to retrieve a website on your web page. HTTPS is a secure and encrypted page used to transfer data from the website page to your browser. The URL tells the browser where to go and the HTTPS tell the browser how to go there and how to retrieve the data. 

    Hedy Lamarr co-developed the frequency-hopping spread spectrum technology that is needed to create wifi, GPS and bluetooth. She started her life as an actress and then co-developed the most important system for wifi. She developed this system in 1942 and is now known as "the mother of Wi-Fi". 

    Bluetooth was developed in the mid 1990's by engineers at Intel, Ericsson, and Nokia. Jim Kardach named bluetooth its name. It was intended to be a temporary name, but then became the final choice. The logo is two runic letters from the vikings alphabet combined. The letters represent the latin letters "H" and :"B". 

    Wifi was developed in the late 1990's. Vic Hayes was the chairman that created the standard and he was called "the father of WIFI". The original name of Wifi was IEEE 802. 11b standard. It was renamed in 2002 to have a more user friendly and marketable name. Wifi was suggested to be the name as a short and catchy logo. 

    Marian Croak is the engineer who invented voice over protocol which changed the way the world communicates. Her work paved the way for zoom, skype, and many phone calls. VoIP converts voice into data packets to allow phone calls. None of the other calling services would be available for use without VoIP.

Introduction

      Hi, my name is Sophia Brown. I grew up in Lynnfield, Massachusetts, which is 20 minutes north of Boston. The college I go to is the University of Tampa with an accounting major and a law, justice, and advocacy minor. I am planning to work in the tax accounting field or become a tax attorney. I love to hang out with friends, workout, go to the beach, and go shopping during my free time. I also love reading, watching movies, and learning new things. I used to play softball and do cheerleading. I still try to stay very active now after stopping playing sports.      The main thing I am hoping to gain from taking digital media is more computer skills than I have currently. I am not very good with using certain softwares on the computer, which I think is a very good skill to have when getting a job. Another skill I hope to gain is becoming more creative. I have a very analytical mind currently, which is important, but having a creative side is also signific...

TagBrush

  I process behind my art piece is to use different tools in photoshop to get the hang of the different material we will be doing. For example, using the brush tool was the main tool I used to create this art piece. Also, using the brackets helped practice making the brush bigger and smaller. Lastly, using layers and the masking tool to create the scratches and shading on around the logo to create a "spray paint" effect. Overall, this piece is meant to be colorful, lively, and practice working on the tools that will be used throughout the course.

Photoshop

 https://youtu.be/IZACwQzj7TQ?si=78f_SPPyyKmPlvJK     This video taught me many important tools about photoshop. For example, using the laso tool is something I think will be used very often to erase things from a picture. The patch tool also seems like something that would be important to use which does a similar thing as the laso tool. Lastly, using layer mask will be important to combine pictures together into one. I think this will be used very often.  https://youtu.be/y_Nqb32auxs?si=knkso-erpFgHd3m7     This video did not have specific words, but showed visuals of how to use certain tools. For example, making copies of layers and then merging them together is a good tool to use incase you need to go back to another layer. This also allows for any mistakes made to the second layer to be able to start over. Learning how to wrap the layer also could be important depending on what projects could be coming during this portion of the course.
