Unit I: Computer Systems and Organisation (10)

● 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)

Unit II: Computational Thinking and Programming – I (45)

● 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: 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 ’ 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().

Unit III: Society, Law and Ethics (15)

● 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.
