Internet and World Wide Web:

    A global network of linked computers and computer networks is known as the Internet. The use of the Internet Protocol (IP), a defined communication protocol, it enables the sharing of resources and information globally. The Internet was first conceptualized in the 1960s, and many people had a hand in its creation. created by the Department of Defense in the United States. The packet-switching technique, which allowed data to be divided into packets and sent independently over the network, was initially used by the ARPANET.

    With the creation of TCP/IP (Transmission Control Protocol/Internet Protocol), a set of protocols that enabled various networks to communicate with one another, the Internet as we know it today began to take shape. TCP/IP is frequently credited to Bob Kahn and Vinton Cerf for its invention in the 1970s. The Internet changed with time, and its use increased. With the advent of the World Wide Web (WWW) in the 1990s, individuals could now more easily access and exchange information using web browsers. The widespread use of the Internet for private, business, and recreational purposes started with this.  

    Nowadays, the Internet is essential to many facets of daily life. It is utilized for messaging apps, social media, and email communication. It acts as a huge information warehouse that facilitates news access, education, and research. People can now shop online thanks to the growth of e-commerce on the Internet. Entertainment is offered by streaming services, and data may be stored and accessed remotely thanks to cloud computing. The Internet now plays a crucial role in how individuals connect, communicate, and get information in today's world.

Web browsers are used to view a network of interconnected hypertext texts and multimedia material known as the World Wide Web (WWW or Web). It was developed to give users a simple way to share and access information on the Internet. Sir Tim Berners-Lee is credited with creating the World Wide Web. The World Wide Web was conceptualized in 1989 by British computer scientist Tim Berners-Lee when he was employed at the European Organization for Nuclear Research, or CERN, in Switzerland. His objective was to develop a system that would make it simple for researchers to exchange and access data between various machines.

When the World Wide Web first came into existence, its main uses were in academia and research, where it let scientists and researchers share knowledge. Nonetheless, the Web swiftly became widely used as web browsers improved in usability and accessibility, and technology became more widely available. The World Wide Web has completely changed how individuals interact with one another, obtain and exchange information, and carry out a variety of tasks in their personal and professional lives.

Though they are not the same, the Internet and the World Wide Web (WWW) are related ideas. A system of interconnected hypertext texts and multimedia information accessible through the Internet is known as the World Wide Web, although the Internet itself is a massive worldwide network of interconnected computers and networks. The World Wide Web is essentially a service or application that runs across the Internet.

Tim Berners-Lee developed the first website, which launched on August 6, 1991. The website was housed on the first server for the World Wide Web, located in Switzerland at CERN, the European Organization for Nuclear Research. In addition to explaining how to make web pages, the initial website offered information about the World Wide Web initiative. Regretfully, the original website no longer exists in its original configuration. To maintain its historical relevance, CERN has restored the original website. By visiting the following URL, you can see the initial website's recreation:

Wi-Fi and Bluetooth and Lamarr:

Actress and inventor Hedy Lamarr, who was born in Austria, made a substantial impact on the advancement of technology that served as the basis for contemporary wireless communication technologies like WiFi and Bluetooth. Hollywood actress Hedy Lamarr, born Hedwig Eva Maria Kiesler in 1914, gained notoriety for her performances in movies from the 1930s and 1940s. Lamarr had a great acting career in addition to a strong interest in science and technology.During World War II, Lamarr, along with composer George Antheil, developed a frequency-hopping spread spectrum communication system. The invention aimed to secure radio communication and prevent enemies from jamming signals. Their invention, patented in 1942, laid the groundwork for technologies like WiFi and Bluetooth.

Frequency-hopping spread spectrum technology transmits radio signals by quickly switching frequencies, increasing its resistance to jamming and interference. The communication protocols utilized in contemporary wireless technologies, such as WiFi and Bluetooth, are based on this idea. Hedy Lamarr is now recognized as a pioneer in the field of wireless communication, although her contributions to technology were not widely appreciated during her lifetime.  

As for a song about Hedy Lamarr, there is a song titled "Hedwig's Lament" in the Broadway musical and later film adaptation "Hedwig and the Angry Inch." However, this song is not specifically about Hedy Lamarr, the actress and inventor, but rather a character named Hedwig in the context of the musical.

The Swedish telecoms corporation Ericsson created Bluetooth technology in the 1990s. Jaap Haartsen and Sven Mattisson, two engineers, were instrumental in the invention of Bluetooth. When they began developing the technique, they were employed by Ericsson's Mobile Communications business. The first version of the Bluetooth specification, known as Bluetooth 1.0, was published in 1999. Bluetooth development started in 1994.  

The term "Bluetooth" comes from both humorous and historical sources. It has the name of Harald "Bluetooth" Gormsson, a Danish monarch who unified Denmark and a portion of Norway in the tenth century. The metaphorical connection to the technology stems from the fact that Bluetooth was developed with the intention of bringing various communication devices, such phones and laptops, together. The initials "H" and "B" in the Nordic runes that were employed in King Harald Bluetooth's old script make up the Bluetooth logo. The initials "H" and "B" in the logo merge to make a bind rune, a character made by fusing two or more runes. The emblem's style honors King Harald Bluetooth's illustrious past.

The name and emblem of Bluetooth are a tribute to the technology's aspiration of facilitating smooth communication and connection between various devices, much like King Harald's successes in bringing many regions together. Engineers at NCR Corporation led by Australian-born engineer and inventor Dr. John O'Sullivan invented WiFi, short for Wireless Fidelity. The creation of WiFi technology was a component of a larger initiative to figure out how to use 2.4 GHz unlicensed radio spectrum for wireless communication.

The initial name wasn't "WiFi" as such. Originally, it was called "IEEE 802.11b Direct Sequence." But to make the term more palatable and marketable, "WiFi" was eventually coined. Interbrand, a marketing firm, created the branding. The name was intended to communicate wireless connectivity in a way that was more user-friendly and approachable. With the rise in popularity of WiFi technology in the late 1990s and early 2000s, it has become an integral and pervasive aspect of contemporary communication, enabling devices to connect wirelessly to local networks and the internet without the use of physical cords.

  Original image- The Bachelor Image before editing Final image Artist Statement- For this project, I decided to put myself into the reality TV show I watch every Monday with my roommates called The Bachelor. This is one of my favorite shows and I used a picture of me dressed up because all of the girls are as well. The scene I picked is during the rose ceremony where Joey decides if he wants the girls to stay or go home.

This is a short video that introduces frame-by-frame animation basics in Photoshop. This tutorial is a short and simple way to learn how to use the paintbrush, layers, frames, and groups to create a character walk through the changing of imagery in Photoshop. It also will learn the different stages that occur in a character walk animation. This quick tip Photoshop Tutorial demonstrates the very basic process of creating traditional frame-by-frame animation within Photoshop. The tools look pretty interesting to use and I am excited to see how I will work with them. They look pretty self-explanatory from this video. This video shows that black-and-white line-art short animations are more popular than ever. I thought the video did a good job explaining how to use the tools we need. It shows how you can get started making your own animations, and the core concepts you need to understand to progress fast.

I decided to do a camera because I love taking pictures and I feel like it is a big part of my life, as will be in 20 years. I used the pen tool to trace the shape of the camera and then the text tool to copy my letter into the camera. I put the text behind the shape and used envelope distortion to make the top object.  Dear Future Self, I hope you are well, surrounded by love, and leading a happy, fulfilling life as I write this letter. I'm amazed at how much time has passed as I sit down to write to you. Two decades have gone by since I wrote these words when I was a 20-year-old girl with big goals and hopes. It seems unreal. Above everything, I sincerely hope you have taken the time to enjoy the ride. Life is precious. Accept the lessons that every moment has to teach you since they help to shape who you become. I hope you haven't lost your sense of awe. I'm interested about where you've gone in life, the experiences you've had, and the people who have grown to b...
