what is cloud computing in simple words

Hi readers,

Many people talk about cloud computing in detail like virtualization,storage, but very few are able to explain ‘term’ in basic simple words.

Reader of this blog will understand the basic but important concept of cloud computing.

 

What is Cloud Computing-

It is a type of computing groups of remote servers and

software networks that allow centralized data storage and

online access to computer services or resources.

Using cloud computing we can manipulate,configure and

access the applications online.

what is opensource and it’s Importance

Hi readers,

I can see currently there are many people are talking about opensource, opensource -projects,techniques, functionality, usability.

Only few have the perfect knowledge of the word/world of opensource.

The reader of this blog will have the good knowledge of opensource.

So go through this blog and earn great knowldge of opensource.

Open-source

Open source refers to a program or software in which the

source code (the form of the program when a programmer

writes a program in a particular programming language) is

available to the general public for use and/or modification from

its original design free of charge

Open source code is typically created as a collaborative effort

in which programmers improve upon the code and share the

changes within the community

Proprietary software is privately owned and controlled. In the

computer industry, proprietary is considered the opposite of

open. A proprietary design or technique is one that is owned

by a company. It also implies that the company has not

divulged specifications that would allow other companies to

duplicate the product

Why to choose open-source

Control

Training

Security

Stability

You can be famous

some basic but imp in python- dir(datatype/varible)

Hi readers,

I am writing this blog ┬ájust to convey you, how python is more efficient even you don’t want remember in built functions of the data structure/variable in python.

Lets say a=[1,2,3,4,5]

a is a dictionary.You want to perform some operation using inbuilt function on this list, but you dont know all the in built function related to list.

So, what the reader of this blog do-

he/she should do dir(a)

and he/she will find the list of all the inbuilt functions.

example-

>>> a=[1,2,3,4,5]
>>> a
[1, 2, 3, 4, 5]
>>> dir(a)
