4.1. Unit-1: Computer Systems and Organization (CSO)

 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

 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

4.2.Unit 2: HTML

 Introduction to web page designing using HTML: create and save an HTML document,
access a web page using a web browser.
 HTML tags: html, head, title, body, (attributes: text, background, bgcolor, link, vlink,
alink), br (break), hr(horizontal rule), inserting comments, h1..h6 (heading), p
(paragraph), b (bold), i (italics), u (underline), ul (unordered list), ol (ordered list), and li
(list item). Description lists: dl, dt and dd. Attributes of ol (start, type), ul (type).
 Font tags (attributes: face, size, color).
 Insert images: img (attributes: src, width, height, alt), sup (super script), sub (subscript).
 HTML Forms: Textbox, radio buttons, checkbox, password, list, combobox.
 Embed audio and video in a HTML page.
 Create a table using the tags: table, tr, th, td, rowspan, colspan
 Links: significance of linking, anchor element (attributes: href, mailto), targets.

4.3. Unit 3: Programming and Computational Thinking (PCT-1)

 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.

 Strings: compare, concat, substring; notion of states and transitions using state transition
diagrams

5.1. Unit-4: HTML Lab

 Create static web pages.
 Use style sheets to enforce a format in an HTML page (CSS).
 Embed pictures, audio and videos in an HTML page.
 Add tables and frames in an HTML page.
 Decorate web pages using graphical elements.
 Work with HTML forms: text box, radio buttons, checkbox, password, list, combo box.

5.2. Unit-5: Programming in Python

 At least the following Python concepts should be covered in the lab
 Sessions: expressions, conditionals, loops, list, dictionary, and strings. The following are
some representative lab assignments.
 Find the largest and smallest numbers in a list.
 Find the third largest number in a list.
 Test for primarily.
 Find whether a string is a palindrome or not.
 Given two integers x and n, compute xn.
 Compute the greatest common divisor and the least common multiple of two integers.
 Test if a number is equal to the sum of the cubes of its digits. Find the smallest and largest
such numb.
