Synchronous communication refers to interaction happening in real-time – a meeting or phone conference, for example.  Asynchronous communication happens anytime and doesn’t rely on being together at the same time – in person or electronically.  E-mail is a good example of asynchronous communication.  Unlike e-mail, asynchronous message boards allow an online discussion to be well-organized into threads.  It is a common technique used in online learning.

Asynchronous refers to fulfilling course objectives through activities that do not need to take place at the same time for all students. An example of an asynchronous activity is the discussion board or threaded discussion, where students post to the board when it is convenient to them as long as the activity is completed by a pre-determined date. This contrasts to synchronous, which means that the activity takes place at the same time for all students.

Asynchronous communication is at the core of Helix Client/Server interaction. Although you may typically think of Helix Client/Server as being driven by the Client, there are a great many things that are initiated by the Server as well. Remember that the Helix Client/Server architecture features live updating of information on the Client's screen. To do this, the Server must be able to initiate contact with a Client when the data they have accessed is changed.

Real-time activities are "live" and immediate. In the context of an online course, a real-time session is one in which all participants are logged on at the same time and interacting at more or less the same pace as one would in a face-to-face setting. A familiar example of real-time communication on the Internet is live chat. Asynchronous activities, on the other hand, are those in which participation is not concurrent or live.

Asynchronous or store and forward consultation involves the exchange of clinical information and static images collected and stored in the telecommunication equipment. The dental practitioner collects all the required clinical information and digital intraoral and extraoral images and radiographs (or scanned, originally nondigital images) and forwards them for consultation and treatment planning via established networks and/or the Internet. E-mail is an example of asynchronous communication.

Asynchronous in the online course means "different times, different places." Entering your course Web site at your convenience and from your location, you access course content and participate in discussions that reinforce your mastery of course concepts.

Well apparently it has to do with something called gene expression, which refers to the pattern in which genes are switched on and off. And gene expression has a major effect on your body's biological processes. Each cell in your body contains a 'power-factory' that produces energy, called the mitochondria.

DCE-RPC is synchronous. The way to make an asynchronous call is to create a thread for each RPC call. You should be able to have dozens, if not hundreds, of threads with no problem. Q 2r-07: How can a server keep track of multiple clients? For example, to know what information has already been provided to a client, and thus vary subsequent responses. The DCE RPC mechanism includes a "context handle" which can be created by a server and returned to a client.

Asynchronous means not at the same time or not in real time. In an asynchronous DE class, the students and instructor "interact" at their own convenience by reading and responding to each other's messages in a computer conference. The computer keeps track, or threads the messages into an on-going discussion. You can see what this looks like by visiting WebTycho and signing in to the TOUR 101 tutorial course.

Isotonic solutions cause no swelling or contraction of the tissues with which they come in contact, and produce no discomfort when instilled in the eye, nasal tract, or other body tissues.

The tonicity of the solution is less than that of the cells. When this occurs, water enters into the blood cells causing them to swell and finally burst, with the liberation of hemoglobin, or water invasion of the body’s cells. If this invasion is beyond the body’s cells, then water intoxication results, with convulsions and edema.

The tonicity of the solution is greater than that of the cells, which can cause a variety of complications, such as, hyperglycemia, intracellular dehydration, loss of water and electrolytes, dehydration and coma.

Here a "hack" is a clever shortcut or a lesser-known, faster way to get something done. A hacker believes that information-sharing is a powerful positive good, and that it is a hacker's duty to share her expertise—so we will.
