4.1 Unit 1: Programming and Computational Thinking
(PCT-2) (80 Theory + 70 Practical)

Revision of the basics of Python

Functions: scope, parameter passing, mutable/immutable
properties of data objects, pass arrays to functions, return
values, functions using libraries: mathematical, and string
functions.

File handling: open and close a file, read, write, and append to
a file, standard input, output, and error streams, relative and
absolute paths.

Using Python libraries: create and import Python libraries
Recursion: simple algorithms with recursion: factorial, Fibonacci
numbers; recursion on arrays: binary search

Idea of efficiency: performance defined as inversely
proportional to the wall clock time, count the number of
operations a piece of code is performing, and measure the time
taken by a program. Example: take two different programs for
the same problem, and understand how the efficient one takes
less time.

Data visualization using Pyplot: line chart, pie chart, and bar
chart.

Data-structures: lists, stacks, queue.

4.2 Unit 2: Computer Networks (CN) (30 Theory + 10
Practical)

Structure of a network: Types of networks: local area and wide
area (web and internet), new technologies such
as cloud and IoT, public vs. private cloud, wired and wireless

networks; concept of a client and server.
Network devices such as a NIC, switch, hub, router, and access
point.

Network stack: amplitude and frequency modulation, collision in
wireless networks, error checking, and the notion of a MAC
address, main idea of routing. IP addresses: (v4 and v6), DNS,
and web URLs, TCP: basic idea of retransmission, and rate
modulation when there is congestion (analogy to a road
network), Protocols: 2G, 3G, 4G, WiFi What makes a protocol
have a higher bandwidth?

Basic network tools: traceroute, ping, ipconfig, nslookup,
whois, speed-test.

Application layer: HTTP (basic idea), working of email, secure
communication: encryption and certificates (HTTPS), network
applications: remote desktop, remote login, FTP, SCP, SSH,
POP/IMAP, SMTP, VoIP, NFC.

4.3 Unit 3: Data Management (DM-2) (20 Theory + 20
Practical)

Write a minimal Django based web application that parses a GET
and POST request, and writes the fields to a file – flat file and
CSV file.

Interface Python with an SQL database

SQL commands: aggregation functions – group by,
having, , order by.

4.4. Unit 4: Society, Law and Ethics (SLE-2) (10 Theory)

Intellectual property rights, plagiarism, digital rights
management, and licensing (Creative Commons, GPL and
Apache), open source, open data, privacy.
Privacy laws, fraud; cyber-crime- phishing, illegal downloads,
child pornography, scams; cyber forensics, IT Act, 2000.

Technology and society: understanding of societal issues and
cultural changes induced by technology.

E-waste management: proper disposal of used electronic gadgets.
Identity theft, unique ids, and biometrics.

Gender and disability issues while teaching and using computers.
