Synchronous & Asynchronous Communication
Using internet, we as user can interacting via 2 ways. The 1st way is by Synchronous and the 2nd way is via Asynchronous. What is both bombastic words means? Here I have elaborate details in words & table to make a better understanding from the reader views.
Synchronous tools enable real-time communication and collaboration in a "same time-different place" mode. These tools allow people to connect at a single point in time, at the same time. Synchronous tools possess the advantage of being able to engage people instantly and at the same point in time. The primary drawback of synchronous tools is that, by definition, they require same-time participation -different time zones and conflicting schedules can create communication challenges. In addition, they tend to be costly and may require significant bandwidth to be efficient.
|Audio conferencing||Discussions and dialogue||Cost, especially when international participation is involved|
|Web conferencing||Sharing presentations and information||Cost, bandwidth; may also require audio conferencing to be useful|
|Video conferencing||In-depth discussions with higher-touch interactions||Cost, limited availability of video conferencing systems|
|Chat||Information sharing of low-complexity issues||Usually requires typing, "lower touch" experience|
|Instant messaging||Ad hoc quick communications||All users must use compatible system, usually best for 1:1 interactions|
|White boarding||Co-development of ideas||Cost, bandwidth; may also require audio conferencing to be useful|
|Application sharing||Co-development of documents||Cost, bandwidth; may also require audio conferencing to be useful|
Asynchronous tools enable communication and collaboration over a period of time through a "different time-different place" mode. These tools allow people to connect together at each person's own convenience and own schedule. Asynchronous tools are useful for sustaining dialogue and collaboration over a period of time and providing people with resources and information that are instantly accessible, day or night. Asynchronous tools possess the advantage of being able to involve people from multiple time zones. In addition, asynchronous tools are helpful in capturing the history of the interactions of a group, allowing for collective knowledge to be more easily shared and distributed. The primary drawback of asynchronous technologies is that they require some discipline to use when used for ongoing communities of practice (e.g., people typically must take the initiative to "login" to participate) and they may feel "impersonal" to those who prefer higher-touch synchronous technologies.
|Discussion boards||Dialogue that takes place over a period of time||May take longer to arrive at decisions or conclusions|
|Web logs (Blogs)||Sharing ideas and comments||May take longer to arrive at decisions or conclusions|
|Messaging (e-mail)||One-to-one or one-to-many communications||May be misused as a "collaboration tool" and become overwhelming|
|Streaming audio||Communicating or teaching||Static and typically does not provide option to answer questions or expand on ideas|
|Streaming video||Communicating or teaching||Static and typically does not provide option to answer questions or expand on ideas|
|Narrated slideshows||Communicating or teaching||Static and typically does not provide option to answer questions or expand on ideas|
|Teaching and training||Typically does not provide option to answer questions or expand on ideas in detail|
|Document libraries||Managing resources||Version control can be an issue unless check-in / check-out functionality is enabled|
|Databases||Managing information and knowledge||Requires clear definition and skillful administration|
|Web books||Teaching and training||Not dynamic and may lose interest of users|
|Surveys and polls||Capturing information and trends||Requires clear definition and ongoing coordination|
|Shared Calendars||Coordinating activities||System compatibility|
|Web site links||Providing resources and references||May become outdated and "broken"|
