What are the Application of tree and graph in data file structures?

Using binary tree, one can create expression trees. The leaves of the expression tree are operands such as constants, variable names and the other node contains the operator (binary operator). this particular tree seems to be binary because all the operators used are binary operators. it is also possible for a node to have one node also, in case when a unary minus operator is used.
we can evaluate an expression tree by applying the operator at the root to the values obtained by recursively evaluating the left and right sub trees.

∙ 14y agotrees and graphs are very important data structures. they are used in compilers and in data base. compiler uses tree structures do convert data types and do calculations on booleans and variables. even the modem on your computer uses a binary tree structure called huffman encoding for data compression.

How do you use Graph in data structure?
Em depends on the points your plotting on the graph. If they are evenly distributed then it's probably a linear graph.

What Name some services provided by the application layers in the internet model?
file, printer, applications, and data base service
Can an application or devce driver specify if it will use physical memory or the swap file for its data?
No, because the O/S call to allocate memory can allocate either physical memory OR swap file space. It's under O/S control, not the application.
Give an example of an application in which data in file should accessed in the following order 1 sequentally 2 Randomly?
Universal Product Codes
Do you need a data file to make a bar graph?
No but you do need a dataset or data range with which to to populate the graph.
What is Data remanence is?
File structures that remain after a file has been deleted
Is a data file needed to make a bar graph?
Yes.
Is a data file needed to make a bar graph Explain?
Yes because you need the data on the right and across the bottom to make the graph
What is a differences between application and file?
an application runs a series of commands. a file is data stored in some retrievable way.
What is meant by API?
An application programming interface (API) is a library of functions that a programming language provides for programmers for common tasks like file transfer, networking, and data structures.
What were the shortcomings of early file-oriented database structures?
data redundancy
What is file structures in C plus plus?
As far as C++ is concerned files do not have structures, they are simply raw data streams. It's entirely down to the programmer to determine what structures exist within the file and to interpret the data accordingly. C++ cannot do it for you.
What is the structures of the files and data bases?
I think file is a open structure. and the data base is closed structure.
How do you display data from existing SQLite file in Android application?
You don't.
How do you use Graph in data structure?
Em depends on the points your plotting on the graph. If they are evenly distributed then it's probably a linear graph.
