2. Which of the following is an example of the hardware component of an information system?

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

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.

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

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

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:

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

The channel which switches the multiple requirements and multiplexes the data transmissions from these devices a byte at a time is recognized as.....

The first concept covered is the transactional nature of communications. Transactional nature of communications essentially

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

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.

Holt and, 1920. 21-25. Print.)

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.

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