This book, Informatics Practices with Python for Class XI (065), has been prepared in accordance with the latest syllabus. The book focuses on teaching Python language to help students learn programming concepts and develop problem-solving skills and RDBMS operations. With easy-to-understand examples, self-explanatory diagrams and other such tools, The student learns to design the logic for a program and then implement that program using Python. In addition, the book contains ample concise and practical example programs along with diagrams and instances from real-life situations. Each br>Chapter consists of tested, debugged and error-free codes with screenshots. Ctm (commit to memory), learning tips and points to Remember for easy recall of important terms and concepts are other notable features of the book. Strictly adhering to the CBSE curriculum and guidelines, The book has been divided into five units: br>Unit I: introduction to Computer system (br>Chapter 1) Introduction to Computer and computing: evolution of computing devices; components of a computer system and their interconnections; input/output devices; concept of computer memory, units of memory, types of memory-primary and secondary; data deletion, its recovery and related security concerns; software: purpose and types-system and application software, generic and specific-purpose software.
