Python was invented by Guido van Russel during his vacations as a new project to create an interpreter . The syntex and procedure he used while creating this interpreter is called python later . Python 3 is the suitable version to all . We all just need to download and install the python package to execute the python scripts on computer .
Python is platform independent can be run on all operating systems , just need to install python package .
Python has an interpreter to execute the scripts and command line for the user interface but command line only executes on command at a time and not a entire script .we can install other IDE like Jupyter to execute the entire python script .
Python syntax is very easy and short because of huse library support that makes it most popular .
Pyhon scripts have the .py extention while saving .

What is Data Structure and Types of data structure

Data Structure is an organized way to store the data through various Linear and Non-Linear ways . Data structures Algorithms are the initial stage to start for programmers of any kind like desktop softwares , mobile applications or web applications . Data Structures contains various algorithms to complete different kind tasks in the programming practicals .


Some of the very popular and useful concepts for the structuring of data in the programmes are –
1.Arrays – Arrays are the collection of the same type of data types . If an element stored in array is Integer type , definitely all other of Integer Data types . All the elements stored in an array are numbered from index 0 to n-1 . This array block covers a block in the memory keeping together its elements at one place . It is a Linear data type structure .
2.Linked Lists – Linked Lists store the data elements in the same way as an array does but linked list can store the elements at different-different positions in the memory and , l…

What is Waterfall Model in Software Development Life Cycle

Now a days Waterfall Model is outdated but it is the oldest model for defining the software development life cycle . Waterfall model shows the various steps of software development process . 
Waterfall model dominated several number of years to the software development life cycle . Software passes through many of the development process and waterfall model shows those steps in very easy linear consecutive steps of development process . 
Waterfall model only starts, when the developers get the complete requirements of the software on which they are working .
Waterfall model is the oldest , classic model and the base of other modern models that are working even today in the software industry .
As we know , software development is not only a process of only coding the softwares , developers cross the various steps like knowing the requirements , makink specifications , designing , coding etc . 
So let we give here a look the various linear consecutive steps of Waterfall Model -

Funda Of Satellites Working and Uses

We use Televisions , Internet , Radio Services , FM but It is knowledgeable that all these can not work without satellites . Satellites make possible any communication or signals transferring from one place to another wirelessely .

What is a Satellite - 
All the objects in the space situated in an orbit moving around one another are satellites but we can categorize satellites in two major categories -

1. Natural Satellite - 
We say Moon is a natural satellite that is moving continously around the earth and many other natural satellites available in the space orbits .

2. Artificial Satellites -
These satellites are human made . There are many big organizations like NASA , ISRO that work to create space satellites to complete particular tasks . NASA , ISRO have launched many of the space satellites that are working to make communicaton easier among countries , states and countries .



Artificial Satellites recieve signals from the one place of earth and transmits to the other place in the f…

What about 3D Printng , Working and Uses

We see 2D printers many times that prints anything we want , on a A4 size paper basically . We all have used 2D printings but it is amazing to thing , we can also print 3D models these days .



If we want to copy a material of 2 meter length and 3 meter width , It is possible and we just need a computer design of that model and a 3D printer .

How 3D Printing works -

To make a copy of anything , any design , we need to create a 3D design using the computer softwares . Many of the new softwares are available in the industry but we can also go with the well known softwares for CAD designs ( Computer Aided Designs ) .

Now we need a 3D printer . When we feed up the computer designs to the 3D printer , It slices that 3d design into thousands of thin layers and starts printing that design layer be layer to convert that 3d design into reality .

Uses of 3D printers -

We can not bound the possibilities of 3d printing uses but 3d printing playing vital role in the major industries and many of the n…
