the data link layer
A frame is the data unit for the data link layer, whereas a packet is the transmission unit of the network layer.
Why do we use DataFrames?
Data frames are useful ways to store data in a tabular fashion that retains the 1-dimensional shape of features while also creating a multi-dimensional matrix. Regardless as to whether one uses Pandas, DataFrames.
What are data frames used for?
A data frame is used for storing data tables. It is a list of vectors of equal length. For example, the following variable df is a data frame containing three vectors n, s, b.

Steps
- Create a two-dimensional, size-mutable, potentially heterogeneous tabular data, df1.
- Print the input DataFrame, df1.
- Create another DataFrame, df2, with the same column names and print it.
- Use the append method, df1.
- Print the resultatnt DataFrame.

What’s the difference between a packet and a frame?
The main difference between a packet and a frame is the association with the OSI layers. While a packet is the unit of data used in the network layer, a frame is the unit of data used in the OSI model’s data link layer. A frame contains more information about the transmitted message than a packet.
What is difference between Dataset and DataFrame?
DataFrames are a SparkSQL data abstraction and are similar to relational database tables or Python Pandas DataFrames. A Dataset is also a SparkSQL structure and represents an extension of the DataFrame API. The Dataset API combines the performance optimization of DataFrames and the convenience of RDDs.

Pandas’ merge and concat can be used to combine subsets of a DataFrame, or even data from different files. join function combines DataFrames based on index or column. Joining two DataFrames can be done in multiple ways (left, right, and inner) depending on what data must be in the final DataFrame.
What is the difference between a map and map frame?
It is called Map by default. The layers are the individual map types (e.g. Contours, Post, Base) used to display your data and the graticules used to convey geographic location. A map frame includes the axes and all the layers. You can see the map components in the Contents window.
