In this lesson, we examine fundamentals of electronic communication and explore how computer communication differs from human communication.
After this lesson, you will be able to
Understand how a computer transmits and receives information
Explain the principles of computer language
Estimated lesson time; 20 minutes
Humans communicate primarily through words, both spoken and written. From ancient times until about 150 years ago, messages were either verbal or written in form. Getting a messenger] got lost in the process.
As time and technology progressed, people developed devices to help them communicate faster over greater distances. Items such as lanterns, mirrors, and flags were used to send messages quickly over an extended visual range. All out earshot communications have one thing in common; they require some type of code to convert human language to a form of information that can be packaged and sent to the remote location. It might be a set of letters in an alphabet, a series of analog pulses over a telephone line, or a sequence of binary numbers in a computer. On the receiving end, this code needs to be converted back to language that people can understand.
Obstacles to effective communications include differences in languages and in how the speaker and listener give meaning to words. Language between people is made up of more than words. Gestures, emphasis, body language, and social concepts have an impact on how we interpret interpersonal communicate
