Scenario You are always communicating with others. You talk to your friends at school. You call them on the telephone. You may show photographs of special events or people to them. You may send letters or e-mail, to those who have moved away. Or, you may have made new friends, many miles distant, by communicating through the Internet. No matter how you communicate, you require a code. Language and pictures are codes you learn from an early age. Talking may feel as natural to you as breathing. But many years ago you had to learn to translate your thoughts and feelings into a code that those close to you could understand. In order to communicate with others you are continually translating your thoughts from one code to another. Code and communication are forever linked.Challenge 1. You are a member of a team of engineers who is developing a communications system. The system must communicate from one room to the next. Since this system is a model for long-distance communication, assume that the other room is far away. Yelling and waving will not work. The requirement is that you are able to send and receive a message. You will have to divide your team into senders and receivers, with the receivers in the other room. You will have about five minutes to set up your system before you test it to meet the requirement. During the test, you must measure the speed of transmission of your system.In this test, the message you will communicate will be simple and brief and may include either text, picture, music, or a combination of these. |
