If all the parties to the communication are taking part in the exchange at the same time, the communication is synchronous. A telephone conference call is an example of synchronous communication. When the participants are not interacting at the same time, the communication is not synchronous, or asynchronous.
The following are examples of synchronous communications:
- Live meeting. Gathering of team members at the same location.
- Audio conference. A telephone call between two individuals or a conference call where several people participate.
- Computer-assisted conference. Audio conference with a connection between computers that can display a document or spreadsheet that can be edited by both parties.
- Video conference. Similar to an audio conference but with live images of the participants. Some laptop computers have built-in cameras to facilitate video conferencing, as shown in Figure 6.1.

- IM (instant messaging). Exchange of text or voice messages using pop-up windows on the participants’ computer screens, as shown in Figure 6.2.

- Texting. Exchange of text messages that are 160 characters or fewer between mobile phones, pagers, or personal digital assistants (PDAs)—devices that hold a calendar, a contact list, a task list, and other support programs. See Figure 6.3.
