100.00 Object Oriented Programming with Python

Concept of Object Oriented Programming:- Data Hiding, Data Encapsulation, Class and Object, Polymorphism, inheritance, advantages of Object Oriented Programming over earlier programming methodologies,

Classes:- Defining classes (attributes, methods), creating instance objects, accessing attributes and methods, using built in class attributes (dict, doc, name, module, bases), Constructor( _ _init()_ _, _ _del()_ _ and _ _ str()_ _) methods in a class, private attributes (limited support), importance of “self” (acts as a pointer to current calling object) operator overloading with methods.

Concept of base class and derived class:- Single, multilevel and multiple inheritance- Overriding methods, using super( ) in derived class to invoke _ _init()_ _ or overridden methods of parent class.

200.00 Advance Programming with Python

Linear List Manipulation:- Sequential allocation, traversal,insertion of an element in a sorted list, deletion of an element from the list, searching (linear, binary), sorting (insertion, selection, bubble).

Stacks (List Implementation):- Introduction to stack (LIFO Operations ), operations on stack (PUSH and POP) and its implementation in python.

Converting expression from infix to postfix notation and evaluation of postfix expression.

Queues (List implementation) - Introduction to Queue(FIFO) , Operations on Queue (INSERT and DELETE) and its implementation in Python.

Data File

Need for data file, types of data file–text and binary,opening and closing files-open( ), close( ), access modes (output, input, default), file object, access_modes, reading and writing a file read(), readline(), readlines(), write(), writelines file positions (seek(), tell()), renaming and deleting a file.,flush();

Implementation of basic file operations on text and binary file in Python:- Creating/writing data into file, reading and displaying data from file, searching for particular data from a file, insertion and deletion of data from an already existing file, modification of data in file.

Error and Exceptions - NameError, IndexError, TypeError, IO Error, ImportError, ValueError, EOFError.

Generator function using Yield.

300.00 Python - Databases and SQL

Data base Concepts:- Introduction to data base concepts and its need.

Relational data model:- Concept of domain, tuple, relation, key, primary key, alternate key, candidate key;

Relational algebra:- Selection, Projection, Union and Cartesian product;

Structured Query Language:-

General Concepts:- Advantages of using SQL, Data Definition Language and Data Manipulation Language;



SQL functions:- SUM ( ), AVG ( ), COUNT ( ), MAX ( ) AND MIN ( ); Obtaining results (SELECT query) from 2 tables using equi-join, Cartesian product and Union

Note:- Implementation of the above mentioned commands could be done on any SQL supported software on one or two tables.

400.00 Python - Boolean Algebra

Role of Logical Operations in Computing.

Binary-valued Quantities, Boolean Variable, Boolean Constant and Boolean Operators: AND, OR, NOT; Truth Tables; Closure Property, Commutative Law, Associative Law, Identity law, Inverse Law, Principle of Duality, Idempotent Law, Distributive Law, Absorption Law, Involution Law, DeMorgan’s Law and their applications;

Obtaining Sum of Product (SOP) and Product of Sum (POS) form the Truth Table, Reducing Boolean Expression (SOP and POS) to its minimal form, Use of Karnaugh Map for minimization of Boolean expressions (up to 4 variables);

Application of Boolean Logic: Digital electronic circuit design using basic Logic Gates (NOT, AND, OR, NAND, NOR)

Use of Boolean operators (NOT, AND, OR) in SQL SELECT statements

Use of Boolean operators (AND, OR) in search engine queries.

500.00 Python - Communication Technologies

Evolution of Networking:- ARPANET, Internet, Interspace Different ways of sending data across the network with reference to switching techniques (Circuit and Packet switching).

Data Communication terminologies:- Concept of Channel, Bandwidth (Hz, KHz, MHz) and Data transfer rate (bps, Kbps, Mbps, Gbps, Tbps).

Transmission media:- Twisted pair cable, coaxial cable, optical fiber, infrared, radio link, microwave link and satellite link.

Network devices:- Modem, RJ45 connector, Ethernet Card, Router, Switch, Gateway, wifi card.

Network Topologies and types:- Bus, Star, Tree, PAN, LAN, WAN, MAN.

Network Protocol:- TCP/IP, File Transfer Protocol (FTP), PPP, SMTP, POP3 Remote Login (Talent), and Internet Wireless/Mobile Communication protocol such as GSM, CDMA, GPRS, and WLL.

Mobile Telecommunication Technologies:- 1G, 2G, 3G and 4G; Mobile processors;

Electronic mail protocols such as SMTP, POP3

Protocols for Chat and Video Conferencing VOIP

Wireless technologies such as Wi-Fi and WiMax

Network Security Concepts:-

Threats and prevention from Viruses, Worms, Trojan horse, Spams
