Cascading Style Sheet (C.S.S.) Cascading Style Sheet – the cascading style sheet is a language for a webpage to style the webpage. The World Wide Web Consortium (w3C) created CSS. CSS describes how Html elements are to be displayed on the screen, on paper, or in other media. CSS saves a lot of work. It controls the layout of multiple WebPages all at once. CSS solved a big problem Html was never intended to contain tags for formatting a web page Html was created to describe the content of a web page like <h1> this is a heading</h> <p>this is a paragraph</p> When tags like<font> and color attributes were added to the html3.2 specification, It started a nightmare for web developers. Development of large websites, where fonts and color information were added to every single page, became a long and expensive process to solve this problem, The World Wide Web Consortium (w3C) created CSS. The CSS removed the style format from the Html page. There are two types of...

  Python 3 vs Python 2 are getting used widely in an organization as per their requirements. Python 2. X is widely used as it is stable for a long time. Python 3. X is also getting into a notice of developers. Developers used to go with python 2 as from python 2 to python 3 transitioning is happening and some of the libraries are not available in Python 3 which is very helpful in python 2. There is the following difference between [ython 3 and python 2. 1.        Print function — In python 3, a print function has been used means arguments should be enclosed in parenthesis. for example print(“this is python3”) instead in python 2, a print is treated as a statement for example print” this is Python2”. 2.        programming language effectiveness— In python 3, syntax changes are done to make the programming language more effective and easy for the developers compared to Python 2. 3.      ...

Python language—Python is a popular programming language it is procedural, (it means it included the c language character c language is procedural oriented language) object-oriented (which means it also follows object-oriented concepts like as c++ language), and functional oriented (it means it is dependent on functions also) language. It is interpreted language (it means its program run on the interpreter.) as we know as before,( three types of language translators are interpreters, assemblers, and compilers ) and the interpreter translation process is done whenever we have to execute the source program) An interpreter checks the program line by line for any errors and then run so it is slower than another language like c++. It was developed by Guido van Rossum and released in 1991. It is used for server side (it means there are two types of web development client side and server side and it is a part of server-side web development) web development, software development, mathematics...

Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. An electrical network is an interconnection of electrical components e.g. batteries, resistors, inductors, capacitors, switches, transistors, etc. or a model of such an interconnection, consisting of electrical elements e.g. voltage sources, current sources Resistance, inductance, capacitance. An electrical circuit is a network consisting of a closed loop, giving a return path for the current. Linear electrical networks are a special type consisting only of sources (voltage or current) and have the property that signals are linearly superimposable (the ability for an object to be placed over another object; without visibility restriction). A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, divide voltages...

Introduction of c++                 C++ is a semi-object-oriented programming language. It was developed by Bjarne Stroustrup at AT & T Bell Laboratories in Murray Hill, New Jersey, USA, in early 1983. C++ is a superset of C. Most of what we already know about c applies to c++ also. Therefore, almost all C programs are also C++ programs. However, there are a few minor differences that will prevent a C program to run under a C++ compiler. The most important facilities that C++ adds to C are classes, inheritance, function overloading, and operator overloading. These features enable the creation of abstract data types, inherit properties from existing data types, and support Polymorphism, thereby making c++ a truly semi-object-oriented language.  The object-oriented features in C++ allow programmers to build large programs with clarity, extensibility, and ease of maintenance, incorporating the spirit and efficiency of C. the additio...
