Detailed syllabus of Computer Science

Unit 1: Programming and Computational Thinking

  • Familiarization with the basics of Python programming: a simple “hello world" program, process of writing a program, running it, and print statements; simple data-types: integer, float, string
  • Introduce the notion of a variable, and methods to manipulate it (concept of L-value and R-value even if not taught explicitly)
  • Knowledge of data types and operators: accepting input from the console, assignment statement, expressions, operators and their precedence.
  • 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, while, flowcharts, decision trees and pseudo code; write a lot of programs: interest calculation, primarily testing, and factorials.
  • Idea of debugging: errors and exceptions; debugging: pdb, break points.
  • Lists, tuples and dictionary: finding the maximum, minimum, mean; linear search on list/tuple of numbers, and counting the frequency of elements in a list using a dictionary. Introduce the notion of accessing elements in a collection using numbers and names.
  • Sorting algorithm: bubble and insertion sort; count the number of operations while sorting.
  • Strings: compare, concat, substring; notion of states and transitions using state transition diagrams.


Unit 2: Computer Systems and Organisation (CSO)

  • Basic computer Organisation: description of a computer system and mobile system, CPU memory, hard disk, I/O, battery, power.
  • Types of software: application, OS, utility, libraries.
  • Language of Bits: 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, unsigned integers, binary addition
  • Strings: ASCII, UTF8, UTF32, ISCII (Indian script code)
  • Execution of a program: basic flow of compilation program  binary  execution
  • Interpreters (process one line at a time), difference between a compiler and an 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 computers, cloud storage (public/private), and brief introduction to parallel computing.


Unit 3: Data Management (DM-1)

  • Relational databases: idea of a database and the need for it, relations, keys, primary key,foreign key; use SQL commands to create a table, keys, foreign keys; insert/delete an entry,delete a table.
  • SQL commands: select, project, and join; indexes, and a lot of in-class practice.
  • Basics of NoSQL databases - Mongo DB.


Unit 4: Society, Law and Ethics (SLE-1) - Cyber safety

  • Cyber safety: safely browsing the web, identity protection, confidentiality, social networks, cyber trolls and bullying
  • Appropriate usage of social networks: spread of rumors, 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.
