The RJ45 connector is a standardized physical interface for connecting ethernet cables, with color specifications for wiring.
RJ45 connectors have 8 pins and are commonly used for Ethernet connections
The color specifications for wiring in an RJ45 connector are typically T568A or T568B standards
T568A wiring uses green and orange pairs, while T568B uses orange and green pairs
For example, in T568B standard, pin 1 is w...
List is mutable while tuple is immutable.
List can be modified while tuple cannot be modified.
List is defined using square brackets [] while tuple is defined using parentheses ().
List is used for homogenous data while tuple is used for heterogenous data.
List is slower than tuple in terms of performance.
Example of list: [1, 2, 3] and example of tuple: (1, 'hello', 3.14)
A .pyc file is a compiled Python file that contains bytecode.
It is created by the Python interpreter when a .py file is imported or run.
It is platform-independent and can be executed on any system with the same version of Python.
It speeds up the execution of Python code as the interpreter does not have to compile the code every time it is run.
It can be deleted without affecting the original .py file, as the interp...
A decorator is a design pattern in object-oriented programming that allows behavior to be added to an individual object, dynamically.
Decorators are used to modify the behavior of a function or class without changing its source code.
They are implemented using the @ symbol in Python.
Decorators can be used for logging, timing, caching, and more.
An example of a decorator is the @staticmethod decorator in Python, which...
A generator is a device that converts mechanical energy into electrical energy.
Generators are commonly used in power plants to produce electricity.
They work on the principle of electromagnetic induction.
The mechanical energy can be provided by various sources such as steam turbines, gas turbines, wind turbines, etc.
Generators can be classified into AC generators and DC generators.
AC generators are used in most pow...
