Detailed NCERT Class 11 Computer Science Syllabus 2025-26

The full CBSE Class 11 Computer Science Syllabus 2025-26 comprises both theoretical and practical courses designed to provide students with hands-on experience with programming languages such as Python, fundamental computer hardware knowledge, and an understanding of ethical technology use. Each unit of the syllabus is clearly duscussed in the table below.

Unit-wise Syllabus of Computer Science Class 11 2026

Unit 1: Computer Systems and Organisation
Basic computer organisation: Introduction to Computer System, hardware, software, input device, output device, CPU, memory (primary, cache and secondary), units of memory (bit, byte, KB, MB, GB, TB, PB)
Types of software: System software (Operating systems, system utilities, device drivers), programming tools and language translators (assembler, compiler, and interpreter), application software
Operating System(OS): functions of the operating system, OS user interface
Boolean logic: NOT, AND, OR, NAND, NOR, XOR, truth tables and De Morgan’s laws, Logic circuits
Number System: Binary, Octal, Decimal and Hexadecimal number system; conversion between number systems
Encoding Schemes: ASCII, ISCII, and Unicode (UTF8, UTF32)Unit 2: Computational Thinking and Programming – I
Introduction to Problem-solving: Steps for Problem-solving (Analyzing the problem, developing an algorithm, coding, testing, and debugging), representation of algorithms using flowchart and pseudocode, decomposition
Familiarization with the basics of Python programming: Introduction to Python, Features of Python, executing a simple “hello world” program, execution modes: interactive mode and script mode, Python character set, Python tokens( keyword, identifier, literal, operator, punctuator), variables, concept of l-value and r-value, use of comments
Knowledge of data types: Number(integer, floating point,complex), boolean, sequence(string, list, tuple), None, Mapping(dictionary), mutable and immutable data types.
Operators: arithmetic operators, relational operators, logical operators, assignment operators, augmented assignment operators, identity operators (is, is not), membership operators (in not in)
Expressions, statement, type conversion, and input/output: precedence of operators, expression, evaluation of an expression, type-conversion (explicit and implicit conversion), accepting data as input from the console and displaying output.
Errors- syntax errors, logical errors, and run-time errors
Flow of Control: introduction, use of indentation, sequential flow, conditional and iterative flow
Conditional statements: if, if-else, if-elif-else, flowcharts, simple programs: e.g.: absolute value, sort 3 numbers and divisibility of a number.
Iterative Statement: for loop, range(), while loop, flowcharts, break and continue statements, nested loops, suggested programs: generating pattern, summation of series, finding the factorial of a positive number, etc.
Strings: introduction, string operations (concatenation, repetition, membership and slicing), traversing a string using loops, built-in functions/methods–len(), capitalize(), title(), lower(), upper(), count(), find(), index(), endswith(), startswith(), isalnum(), isalpha(), isdigit(), islower(), isupper(), isspace(),lstrip(), rstrip(), strip(), replace(), join(), partition(), split()
