d) The information is acquired on the data bus and send it to TDO. (Alghafli, Jones, and Martin. 2012).

a. You input information perhaps via a keyboard or mouse to the computer and you receive output via a monitor or printer or some such device

Information is composed into a unit (called an edge) and sent over a system to a destination that confirms its effective entry likewise deals with the stream or pacing at which information is sent.

If a device does not know how to get to a destination, it sends data to this device.

• “Data Link -Whenever two or more nodes share the same physical medium (for example, several computers plugged

But per the question, we need to use (2 x 10^8 m/s) for the propagation delay.

2. (5 points) How long does light take to travel to the Earth from the moon?

Data communication is the exchange of data between a sender and a receiver of the information. The components data communication has to have, to be a data communication are:

A signal can lose energy due to the resistance of the medium. This is called _______.

Transmission Path Level: This extends between network elements that assemble and disassemble the payload of a transmission system. For end-to-end communication, the payload is end-user information. For user-to-network communication, the payload may be call-control signaling information (call setup and call termination). Cell delineation and header error-control functions are required at the end points of each transmission path.

The speed of light in a vacuum is 299,792,458 meters per second. The first discussion about the speed of light was by Aristotle, where he quoted another scientist saying that the light from the sun must take some time to reach the earth, but he himself actually disagrees, and even Descartes thought that light traveled instantaneously. The most supported “theorem” about light was

Finally, the application layer of System B passes the information to the recipient application program to complete the communication process.

2. Information Exchange (Clear, understandable speech, initiates communication for task, seeks facts, expression of feeling toward activity, displays emotion related to task, shares information with others, communicates for appropriate length of time)

With the two channels of communication, there is also certain directions information is passed. Upward, downward,

However this is not the same for the beam of light fired from the laser pointer. This is because light is an electromagnetic wave that is independent of the motion of its starting point. It will always travel at 299,792,458 m/s because light’s speed only depends on the medium through which it travels and the motion of the object it is created from is completely irrelevant.
