Finite Element Method (FEM) is a numerical technique for solving partial differential equations by dividing the domain into smaller elements and solving for the behavior of each element. Finite Difference Method (FDM) approximates derivatives by discretizing the domain into grid points and computing the derivative at each grid point. FEM is more versatile in handling complex geometries, while FDM is simpler to implement for regular grids.

What is the relation between the path difference and phase difference?
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
What is the difference between 164 and 220?
The difference between 164 and 220 is 56.
Define the 'potential difference between the ends of a conductor'?
Potential difference between the ends of a conductor refers to the electrical energy difference per unit charge between two points in the conductor. It is commonly known as voltage and is measured in volts. A potential difference is necessary for the flow of electric current in a conductor.
How much is the potential difference between the terminals of a connection wire?
The potential difference between the terminals of a connection wire is determined by the voltage difference applied across the wire. This voltage difference creates an electric field within the wire that causes charge carriers to move and establish a potential difference between the terminals.
What is the difference between the lowest temperatures?
The difference between the lowest temperatures refers to the numerical value that represents the interval between the two lowest recorded temperatures. It is the result of subtracting the lower temperature from the other to determine their difference.
What is the difference between frequency division multiplexing and freq division multiple access?
The basic difference between fdm and fdma is that fdm is used in wired system where as fdma is used in wireless communication.
What is the difference between FDM and OFDMA?
* FDM - hava a guard band , if the band width for the data is x * OFDM - no guard band , x/2 band with
What are the differences between FDM and TDM?
FDM vs. TDMTDM (Time Division Multiplexing) and FDM (Frequency Division Multiplexing) are two methods of multiplexing multiple signals into a single carrier. Multiplexing is the process of combining multiple signals into one, in such a manner that each individual signal can be retrieved at the destination. Since multiple signals are occupying the channel, they need to share the resource in some manner. The primary difference between FDM and TDM is how they divide the channel. FDM divides the channel into two or more frequency ranges that do not overlap, while TDM divides and allocates certain time periods to each channel in an alternating manner. Due to this fact, we can say that for TDM, each signal uses all of the bandwidth some of the time, while for FDM, each signal uses a small portion of the bandwidth all of the time.TDM provides greater flexibility and efficiency, by dynamically allocating more time periods to the signals that need more of the bandwidth, while reducing the time periods to those signals that do not need it. FDM lacks this type of flexibility, as it cannot dynamically change the width of the allocated frequency.The advantage of FDM over TDM is in latency. Latency is the time it takes for the data to reach its destination. As TDM allocates time periods, only one channel can transmit at a given time, and some data would often be delayed, though it's often only in milliseconds. Since channels in FDM can transmit at any time, their latencies would be much lower compared to TDM. FDM is often used in applications where latency is of utmost priority, such as those that require real-time information.FDM and TDM are often used in tandem, to create even more channels in a given frequency range. The common practice is to divide the channel with FDM, so that you have a dedicated channel with a smaller frequency range. Each of the FDM channels is then occupied by multiple channels that are multiplexed using TDM. This is what telecoms do to allow a huge number of users to use a certain frequency band.Read more: Difference Between FDM and TDM | Difference Between | FDM vs TDM http://www.differencebetween.net/technology/difference-between-fdm-and-tdm/#ixzz1x12BskVn

How can you change the downloaded files in FDM?
To change the files in FDM just open the folder and use a converter to change the files.
What is the difference between a French stick and a baguette?
la baguette (fem.) is the usual French name for a 250-grams, stick-like loaf of bread. You would call it French stick.
What advantages does TDM have over FDM in a circuit switched network?
TDM and FDM are multiple access techniques used for multiplexing number of signals into a single single for bandwidth saving. FDM is older technique of multiplexing whereas TDM is relatively a newer technique of multiplexing. TDM advantage over FDM is that it offers bandwidth saving and there is low interference between the signals that are being multiplexed.
