Unit I: 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, 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()

• Completion of the Mid-Term Syllabus by 15th September 2023
• MID TERM EXAM
● 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()).

Unit III: Society, Law and Ethics

● 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
