A computer system primarily comprises of a central processing unit, memory, input/output devices, and storage devices. All these components function together as a single unit to deliver the desired output. A computer is an electronic device that can be programmed to accept data (input), process it and generate result (output).
A number system is a method to represent (write) numbers. Every number system has a set of unique characters or literals. The count of these literals is called the radix or base of the number system. Decimal Number Systems, Binary Number Systems, Octal Number Systems, Hexadecimal Number Systems,

Introduction to Problem Solving Notes Topics: Introduction to problem solving: Steps for problem solving ( analysing the problem, developing an algorithm, coding, testing and debugging). Representation of algorithms using flow chart and pseudo code, Decomposition Introduction Computers is machine that not only use to develop the software. It is also used for solving various day-to-day
Getting Started with Python Programming Language Topics: Introduction Python is an open-source, object-oriented, high-level programming language developed by Guido Van Rossum in 1990, and released in 1991, at the National Research Institute for Mathematics, Netherlands. Presently owned by Python Software Foundation (PSF). Python is influenced by two programming languages: ABC language, a teaching language created to replace the programming

Data Handling in Python Topics are discussed: Operators: arithmetic operators, relational operators, logical operators, assignment operator, augmented assignment operators, identity operators (is, is not), membership operators (in, not in), precedence of operators Expressions, statement, type conversion: expression, evaluation of an expression, python statement, type conversion (explicit & implicit conversion) Debugging / Errors: syntax errors, logical
Flow of Control Topics: Introduction The order of execution of the statements in a program is known as flow of control. The flow of control can be implemented using control structures. Python supports two types of control structures—Selection and Repetition. Indentation Leading whitespace (spaces and tabs) at the beginning of a statement is called indentation.
