Unit 1: Computer Systems and Organisation

• Basic  computer organisation:  description  of  a computer system and mobile system, CPU,  memory, hard disk, I/O, battery.

• Types of software: application, System, utility.

• Memory Units: bit, byte, MB, GB, TB, and PB.

• Boolean logic: OR, AND, NAND, NOR, XOR, NOT, truth tables, De Morgan’s laws

• Information representation: numbers in base 2, 8, 16, binary addition

• Strings: ASCII, UTF8, UTF32,  ISCII (Indian script code), Unicode

• Basic concepts of Flowchart

• Concept of Compiler & Interpreter

• Running a program: Notion of an operating system, how  an operating system runs a program, idea of loading, operating system as a resource manager.

• Concept  of  cloud  computing,  cloud  (public/private),  introduction  to  parallel computing.

CBSE Class 11 Syllabus 2019-20: All Subjects

Unit 2: Computational Thinking and Programming

Basics of Computational Thinking: Decomposition, Pattern Recognition/ Data representation, Generalization/ Data Abstraction and algorithm.

Familiarization  with  the  basics  of  Python  programming: a simple “hello world" program, process ofwriting a program (Interactive & Script mode), running it, and print statements; simple data-types: integer, float, string

• Features of  Python, Python Character Set, Token & Identifiers, Keywords, Literals, Delimiters, operators.

• Comments: (Single line & Multiline/Continuation statements), Clarit & Simplification of expression.

• Introduce the notion of a variable, and methods to manipulate it (concept of L- value and R-value evenif not taught explicitly).

• Knowledge  of  data types and operators: accepting  input  from  the console, assignment statement,expressions, operators and their precedence.

• Operators & types: Binary  operators-Arithmetic,  Relational  operators, Logical

Operators, Augmented Assignment operators.

• Conditional  statements: if, if-else,  if-elif-else;  simple  programs: e.g.: absolute value, sort 3 numbers,and divisibility.

• Notion   of  iterative   computation   and  control   flow:   for(range(),len()),   while, flowcharts, suggested programs: interest calculation and factorials, etc.

• Idea of debugging: errors and exceptions; debugging: pdb,  break points.

• Lists,  tuples  and  dictionary:  finding  the  maximum,  minimum,  mean;  linear search on list/tuple ofnumbers, and counting the frequency of elements in a list using a dictionary. Introduce the notion ofaccessing elements in a collection using numbers and names.

• Sorting  algorithm:  bubble  and insertion  sort;count the number of  operations while sorting.

• Strings: Traversing, compare, concat, substring.

• Introduction to Python modules: Importing math (sqrt, cell, floor, pow, fabs, sin, cos,  tan,  random  (random, randint,  randrange),  statistics  (mean,  median, mode) modules.

Unit 3: Data Management

• Relational databases: Concept of a database, relations,  attributes  and tuples, keys- candidate key, primary key, alternate key, foreign key;Degree and cardinality of a table.

• Use  SQL   –  DDL/  DML  commands  to   CREATE   TABLE,  INSERT   INTO, UPDATE  TABLE , DELETE  FROM,  ALTER TABLE,MODIFY TABLE, DROP TABLE, keys, and foreign keys; to view content of a table: SELECT-FROM- WHERE-ORDER BY alongwith BETWEEN,  IN, LIKE, (Queries only on  single table)

• Aggregate functions – MIN, MAX, AVG, COUNT, SUM

• Basics of NoSQL databases.

Unit 4: Society, Law and Ethics - Cyber safety

• Cyber safety:  safely   browsing   the  web,  identity   protection,   confidentiality, social networks, cyber trollsand bullying

• Appropriate usage of social networks: spread of rumours, and common social networking sites (Twitter, LinkedIn, and Facebook) and specific usage rules.

• Safely accessing web sites: adware, malware, viruses, Trojans

• Safely communicating data: secure connections, eavesdropping, phishing and identity verification.

• Find the largest and smallest numbers in a list.

• Find the third largest number in a list.

• Test for primarily.

• Find whether a string is a palindrome or not.

• Given two integers xand n, compute xn.

• Compute the greatest common divisor and the least common multiple of two integers.

• Test if a number is equal to the sum of the cubes of its digits. Find the smallest and largest such numbers.

2. Data Management: SQL Commands At least the following SQL commands should be covered during the labs: create, insert, delete, select, and join. The following are some representative assignments.

• Create a student table with the student id, name, and marks as attributes where the student idis the primary key.

• Insert the details of a new student in the above table.

• Delete the details of a particular student in the above table.

• Use the select command to get the details of the students with marks more than 80.
