Communication Systems and Information Technology
Communication theory deals primarily with systems for transmitting information from one point to another. The source output represents a voice waveform, a sequence of binary digits from a magnetic tape, or target in a radar system. The channel may represent a telephone line, a high frequency radio link, a space communication link, or a storage medium.
As it is known, in the early 1940’s a mathematical theory for dealing with more fundamental aspects of communication systems was developed. The distinguishing characteristics of this theory are, first, a great emphasis on probability theory, and second, a primary concern with the encoder and decoder. This concerns their functional roles and their achieving a given level of performance. Later information theory was extended and applied in practical communication system.
Information technology is the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware. Information technology deals mainly with the use of electronic computers and computer software to convert, store, protect, transmit as well as securely retrieve information.
Today the term information technology includes many aspects of computing and technology and covers many fields. Information technology professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. The duties of IT specialists may involve data management, networking, engineering computer hardware, database and software design, as well as the management and administration of the whole system. When computer and communication technologies are combined, the result is information technology, or “infotech”. Information technology describes any technology that helps to produce, manipulate, store, communicate and or disseminate information.
I am completely keen on reading. I try to read every day at least a few pages. I like fantasy stories and some adventurous stories. And there is a story of that kind I am eager to read over and over again. Its name is “Harry Potter.” The story was written by a popular British writer J. K. Rowling. And it tells us about a little boy Harry who lives in a family of his aunt. One day he finds out that he is a wizard and should go to study to a school of magic — Hogwarts. And that’s where the story begins. In the following 7 parts we get to know what a great wizard Harry is. He meets new friends, studies, does sport and conquer the most evil magician in the world. These books teach how to be friendly, loyal and strong. They show us how to face difficulties and how important a family and friends are. I love this book for all of this. I have already read it a few times. And I know that I will definitely read it once again.
As far as I remember myself, I had a particular interest to advertising. I`d even like to enter the advertising department of our local university. For sure, I`ve already basically decided what I want to do when I grow up. I`d really like a job where I can apply my creative skills. Consequently, I`d like to have a job of a creative director in an advertising agency.
Frankly, I`m keen on this idea since I watched a wonderful film `99 francs` based on the novel of Frederic Begbeder. It`s a really outstanding film about advertising industry.
As I have already said, the work of art director requires creativity. I`m mad about arts, more than that, I really enjoy watching adverts on TV. The way the ad motivates the person to do something seems really fascinating. I also strongly believe that the work of creative director can be compared with the work of artist; to put it in another way, a good advertisement is really an art object.
All in all, I strongly believe that if I will be persevering and purposeful, all is possible. However, I`m absolutely convinced that without good grades at school the success in your future career is out of the question.
