● 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, NOT, 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)

● 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()

● Lists: introduction, indexing, list operations (concatenation, repetition, membership and

slicing), traversing a list using loops, built-in functions/methods–len(), list(), append(),

extend(), insert(), count(), index(), remove(), pop(), reverse(), sort(), sorted(), min(), max(),

sum(); nested lists, suggested programs: finding the maximum, minimum, mean of numeric

values stored in a list; linear search on list of numbers and counting the frequency of

elements in a list.

● Tuples: introduction, indexing, tuple operations (concatenation, repetition, membership

and slicing); built-in functions/methods – len(), tuple(), count(), index(), sorted(), min(),

max(), sum(); tuple assignment, nested tuple; suggested programs: finding the minimum,

maximum, mean of values stored in a tuple; linear search on a tuple of numbers, counting

the frequency of elements in a tuple.

● Dictionary: introduction, accessing items in a dictionary using keys, mutability of a

dictionary (adding a new term, modifying an existing item), traversing a dictionary, built-in

functions/methods – len(), dict(), keys(), values(), items(), get(), update(), del(), del, clear(),

fromkeys(), copy(), pop(), popitem(), setdefault(), max(), min(), sorted(); Suggested

programs: count the number of times a character appears in a given string using a

dictionary, create a dictionary with names of employees, their salary and access them.

● Introduction to Python modules: Importing module using ‘import <module>’ and using from

statement, importing math module (pi, e, sqrt(), ceil(), floor(), pow(), fabs(), sin(), cos(),

tan()); random module (random(), randint(), randrange()), statistics module (mean(),

median(), mode()).

● Digital Footprints

● Digital Society and Netizen: net etiquettes, communication etiquettes, social media

étiquettes

● Data Protection: Intellectual property rights (copyright, patent , trademark), violation of

IPR(plagiarism, copyright infringement, trademark infringement), open source software and

licensing (Creative Commons, GPL and Apache)

● Cyber Crime: definition, hacking, eavesdropping, phishing and fraud emails, ransomware,

cyber trolls, cyber bullying

● Cyber safety: safely browsing the web, identity protection, confidentiality

● Malware: viruses, trojans, adware

● E-waste management: proper disposal of used electronic gadgets.

● Information Technology Act (IT Act)

● Technology and society: Gender and disability issues while teaching and using computers
