DATA STRUCTURES AND ALGORITHMS
Hello everyone,
My name is Shivangi Pandey,i prepared some notes related to DATA STRUCTURES AND ALGORITHMS ,which is most important for getting placements .So,lets start:)
So, first know what data structures is:-Data structures are the arrrangement of data in such a way so, that they can used efficiently in main memory i.e RAM(Random access memory),all the data are first load in RAM and other processing starts.
Ex: array, linked list, queue, stack etc
Now, what is algorithms?
In very simple words, algorithms are the sequence of steps on data to solve the given problem by using efficient data structures.For understanding, lets say
For ex: Sorting of an array ,Input given :- 1 7 9 2 ,Problem :- Sorting the elements in ascending order and Output will be: 1 2 7 9 ,so in this we have a problem statement given to sort the elements and we have to use some sequence of steps to solve that by using efficient data structures.This is called Algorithms.
There are some other terminology which are important:-
- DATABASE
Database is a collection of information in permanent storage i.e hard disk ,hard drive for faster retrieval and updation.Ex: MySQL, Microsoft Access,MangoDB etc.
2. DATA WAREHOUSING
Data warehousing is the management of huge amount of data i.e legacy data for better analysis.Now ,question arises that what is legacy data? legacy data are essential information that is stored in an old format or computer system which makes it difficult to access and process.so, these data are stored in new database .
3.BIG DATA
It is the analysis of too large and complex data which cannot be dealt with traditional data processing application.Ex: social media sites, search engines,stock exchanges etc.
So, these are some terminologies which are important terms for placements.We have to be aware of all these terms .DATA STRUCTURES AND ALGORITHMS are nothing new .If you have done programming in any language like C , C++ ,you must know what is array, data structures , how to solve problem by using algorithm.
I cover all the topics related to that ,keep in tough with me guys .
STAY FIT STAY SAFE
THANK YOU
