Document Summary

General communication: synchronous communication requires both the sender and receiver are active at the same time. For example, telephone conversation: perform two parts, sending (talking, receiving (iistening, asynchronous communication the sending and receiving occur at different times. For example, sending an email and replying, postcard, text message: broadcast communications a single sender and many receivers. dealing number of receivers. For example, radio, tv: multicast when there are many receivers but the intended recipients are not the whole population. For example, magazine covering specialized topics: point-to-point communication opposite of broadcasting and multicast communication. For example telephone or text messages because there is one specific sender and one specific receiver: property of broadcast vs. point-to-point communications is separate from the property of synchronous vs. asynchronous communication. Internet is fast enough to mimic synchronous communications. (e. g, skype) Internet becomes more efficient with each additional computer added to it.
