Computer Science — Class 11

CBSE (Indian Curriculum) · Ages 16-17

CBSE Class 11 Computer Science (Code 083) teaches programming in Python from first principles and establishes the computational thinking assessed in Class 12.

Content covers computer systems and organisation, Python fundamentals including data types, operators, control flow, strings, lists, tuples and dictionaries, functions, and an introduction to problem solving and algorithm design. It also covers society, law and ethics in computing.

The practical component carries real weight, and Class 12 assumes complete fluency with lists and dictionaries — so this is a year where consistent coding practice matters far more than memorising syntax.

Key topics covered

• Computer Systems — Hardware, software, memory, number systems and data representation.
• Python Fundamentals — Data types, operators, expressions, input and output, and control flow.
• Strings, Lists & Tuples — Indexing, slicing, built-in methods and traversal.
• Dictionaries — Key-value pairs, methods and using dictionaries to solve problems.
• Functions — Defining functions, parameters, return values and scope.
• Problem Solving — Algorithm design, flowcharts, decomposition and debugging.
• Society, Law & Ethics — Digital footprint, cyber crime, IP rights and safe practice.
