Only 2 commands are needed to access the Wi-Fi password from a PC connected to the Wi-Fi already. (actually 1)
Change the color of the fonts with: color 0a
The ultimate command: netsh wlan show profiles "Wi-Fi name" key=clear

IaaS, SaaS or PaaS?

Noor E Jannat Nafia — Sun, 30 Jul 2023 21:06:19 +0000

The basic key points of the 3 Cloud Computing services include:

IaaS(Infrastructure as a service): The cloud provider is responsible for maintaining the infrastructure (hardware, network connectivity (to the internet), and physical security). You’re responsible for maintaining the platform (operating systems, middleware, development tools) and software (data and apps).

PaaS(Platform as a service): The cloud provider is responsible for maintaining the infrastructure (hardware, network connectivity (to the internet), and physical security) and platform (operating systems, middleware, development tools). You’re responsible for maintaining the software (data and apps).

SaaS(Software as a service): The cloud provider is responsible for maintaining the infrastructure (hardware, network connectivity (to the internet), and physical security), platform (operating systems, middleware, development tools) and software (data and apps). You’re responsible for maintaining nothing.

Iteration or Recursion?

One of the most common misconception or jeopardy arises when encountering Data Structure & Algorithms.

Iteration:
Iteration is the repetition of a process.

Recursion:
Recursion is the process of calling a certain function by itself.

The definitions might make them appear similar. However, there are several differences among them to differentiate them properly.

Iteration	Recursion
Set of instructions is repeated.	The function calls itself.
Iteration consists of initialization and conditions.	Recursion consists of base case (termination condition) only.
Infinite iteration can occur when the condition never becomes false.	Infinite recursion can occur when the base case(s) can never be reached.
Iteration uses a data structure called stack.	Recursion does use stack.
Fast in execution.	Slow in execution.
The codes of iteration are usually longer.	The codes of recursion are usually shorter.

Using Current Date & Time in Python

Noor E Jannat Nafia — Thu, 16 Feb 2023 16:45:06 +0000

If we want to use present date, we need to use python library.

At first, we need to need to import the required library.

Then, save the date in a variable and print it, or use it as per need.

Arithmetic Operations - Python - Part 1

Noor E Jannat Nafia — Tue, 10 Jan 2023 06:17:54 +0000

Several data types:

number: integer, float, complex
string
print statement
list
dictionary
boolean
tuple
set

NUMBER:

A number can be either an integer or a float.
An integer is a whole number.
Integer - 3, 6, 8, 445, 34567, 65434
A float is a decimal number.
Float - 1.0, 0.5, 2.33, 765.67, 1.33

Arithmetic operations can be executed on numbers, such as:

Addition: Sum of 2 numbers
Subtraction: Difference between 2 numbers
Multiplication: Product of 2 numbers
Division: Quotient of 2 numbers
Floor Division: Quotient of 2 numbers, except the fractional part
Exponentiation: A number raised to the power of another number Which is the same as:
Modulus: Reminder after division division of 2 numbers

Python follows BODMAS rule.
B-Bracket
O-Of
D-Division
M-Multiplication
A-Addition
S-Subtraction
