21st Century Information Technology

21st Century Information Technology Considering that I’m in the middle of preparing a presentation for another class on the topic of virtual reality (VR), I find it appropriate to begin this current project with Bolter’s and Grusin’s discussion about virtual reality. They posit that “virtual reality is immersive, which means that it is a medium whose purpose is to disappear” (p. 24). They argue that the disappearing act is near impossible because of all the apparatus that the user is required to wear. They further argue that “in order to create a sense of presence, virtual reality should come as close as possible to our daily visual experience.” Its graphic environment should be continuous and full of objects and should fill the user's field of vision without rupture. By rupture, they mean anything that disrupts or betrays the reality that one is attempting to create. The creators of VR systems would ideally like it to be a perfect example of immediacy. It is closer to bein...

Computing

Computing Introduction Computers can be classified into five generations and these are based on when major technological advances in computers occurred. For example, the use of vacuum tubes, transistors, and the microprocessor all signaled major developments and improvements in computer technology. Due to the sustained development and improvement of the computer, it is easy to fathom how they have become intertwined with our lives. As a result of the various improvements to the development of the computer we have seen the computer being used in all areas of life. It is a very useful tool that will continue to experience new development as time passes. First Generation (1940-1956) The first generation of computers used  vacuum tubes  as a major piece of technology. Vacuum tubes were widely used in computers from 1940  through 1956 . Vacuum tubes were larger components and resulted in first generation computers being quite large, taking up a lot of space in a...

Electronics: The War of the Worlds Broadcast and Communications Theory

Image
The War of the Worlds Broadcast and Communications Theory The invention of the telegraph showed society what was possible with communications technology. It also meant that we would want to test these possibilities and keep reaching for more. Guglielmo Marconi is generally credited as the inventor of radio. Marconi worked on converting radio waves  from the telegraph to communication, by building the first radiotelegraphy system. On 27 July 1896, in the UK, Marconi successfully demonstrated his wireless telegraphy system by sending a signal between two Post Office buildings. Before radios received widespread popularity, they were primarily used by the military to exchange messages with the armed forces in real time, without the need for physical messengers. After World War I, small stations began operating using technologies that had developed during the war. Many of these stations developed regular programming that included religious sermons, sports, and news. C ivi...
