    The past few weeks in my life have really had an impact on me. In such a short period of time, I have become more aware of the different cultures that exist around the world today. We tend to think that our way of life is the only way there is, or at least the only right way. It is very ignorant to think that everyone believes and behaves the same way. People should stop being so self-centered and take notice and interest in cultural diversity. There are numerous different cultures in our country alone.One in particular is the Amish culture, which I would like to familiarize you with. The Amish culture consists of many unique beliefs that makes their ways unlike that of any other culture. They lead a life of simplicity and yet have very harsh ways of doing things. The Amish is perhaps the most diverse culture in the entire United States.…

    Computer Hardware

    Computer Hardware came about when machines needed separate manual actions to be able to perform specific mathematical functions. Luckily in 1941, a man by the name of Konrad Zuse invented what was considered the first working, fully operable computer. Prior to this, most of the calculations were done manually to calculate by people with adding machines. Today these adding machines are better known as calculators. Back then, all you had to do is push buttons, but in today’s modern software technology it has been made easier to utilize all of a computers functions and as well as been simplified thanks to computer hardware and all of its wonderful components.…

Computer hardware refers to the physical parts or components of a computer such as monitor, keyboard, hard drive disk, mouse, printers, graphic cards, sound cards, memory, motherboard and chips, etc. all of which are physical objects that you can actually touch. In contrast, software is untouchable. Software exists as ideas, application, concepts, and symbols, but it has no substance. A combination of hardware and software forms a usable computing system.…

    Answer: Computers have become an indispensable tool in the handling of money and finances. Computerized ATM machines and credit card machines are now familiar throughout the United States and in many other countries in the world. Although they have only been in existence for a short while, many of us now take them for granted and expect our bank to provide these computerized services whenever and wherever we need them. Many do not realize that these machines are part of the huge electronic network that has been put in place in the banking and financial services industries. The ATM machines and the credit card machines provide our interface with the bank's computers.…

    Use of Computer

    It seems that more and more often computers and related equipment are being involved in the educational process nowadays. This tendency of wiring schools, exercising long distance learning, and depending on the internet for information is apparently being actively promoted. Lately, politicians and some educators have begun praising computers as the new technological universal remedy, “the one that will turn classrooms into cybernetic gardens for growing young minds” (EMC Paradigm Publishing). The utilization of computers in education has speedily altered the way that people learn in a short period of time. However, there is a topical question of whether this change is for good, whether it have actually repressed or improved learning process? Considering the experience of recent years, when such things as educational television and the language lab failed to truly become a successful educational technology, many individuals nowadays feel skeptical over the noises about computer’s potential to modernize both teaching and learning processes. I believe this skepticism to be vain. In my opinion, the difference this time is that the technologists may be right. I believe that if being applied properly, education through computers can bring numerous significant benefits to both students and teachers.…
