What is the difference between digital terrain model and digital elevation model?
DTM = Digital Terrain Model is a digital representation of the sloped contour surface of the earth. Surface features, such as man-made objects and vegetation, are not included. DEM = Digital Elevation Model is a digital representation of the sloped contour surface of the earth. Elevation data is included, along with surface features such as man-made objects and vegetation.

How is the channel used in the digital communucation system?
The channel used in a digital communication system is used to convey an information signal. A channel has certain capacity for putting in information that is measured by bandwidth in Hz or data rate.

Which device is used to convert analog signals to digital signals?
In datacommunications this is a modulator/demodulator, commonly known as a modem. In electronics a digital to analog converter (DAC) chip is used to convert digital signals to analog and an analog to digital converter (ADC) chip to convert analog signals to digital. Some chips are available which include both ADC and DAC functionality. There are thousands of different types of DAC and ADC sytems and which one to use largely depends on how fast you want to do the conversion.

What CD is used for storing digital data stands for what?
clean data
What is the device used to convert data from digital to analog?
modulator
What are the data used in VHDL?
VHDL is a hardware description language which is used to describe digital circuits or systems. The data involved digital systems is logical data i. e. 0 or 1. Hence, VHDL uses logical data as input and provides the same type of data in output.
Is PCM is an example of analog to digital?
No, Pulse Code Modulation is a communication method used to carry digital data but is not part of any analog to digital conversion. PCM is often used to carry audio data as a digital stream and therefore is the encoding used as the signal is first converted to a digital format.
How do digital dashboard and data mining applications differ from transaction processing applications?
Digital dashboard and data mining applications do not generate new data, but instead are used to summarize existing data to provide information to management
What system used 1's and 0s to represent data?
Digital
What is a card reader used for?
A SDHC Card Reader is used to read secure digital cards. Secure digital cards are used for recording data on digital cameras, GPS devices, phones and tablets.
What is encoding technique?
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
Why must sound and video input to a PC be converted from analog to digital?
Because in order to preserve the original sound, a digital sampling rate must be twice the frequency of the analog signalAnalog data is smooth and continuous, where as digital data, such as the binary data used in computers, has distinct gradations. The process of producing digital data by measuring data at a series of representative points is called sampling.
What is the predominant technique used to send data on digital networks?
circuit switching.
What map would you use to find the elevation in a state?
To find the elevation in a state, you would use a topographic map. Topographic maps depict elevation through contour lines, which represent different elevation levels above sea level. By examining these lines, you can determine the elevation of specific areas, as well as identify features such as mountains, valleys, and plateaus. Additionally, digital elevation models (DEMs) can provide detailed elevation data in a more interactive format.
