12 STD || PYTHON CLASSES AND OBJECTS || PART-3
Introduction
Python is an Object Oriented Programming language. Classes and Objects are the key features of Object Oriented Programming. Th eoretical concepts of classes and objects are very similar to that of C++. But, creation and implementation of classes and objects is very simple in Python compared to C++.
Class is the main building block in Python. Object is a collection of data and function that act on those data. Class is a template for the object. According to the concept of Object Oriented Programming, objects are also called as instances of a class or class variable. In Python, everything is an object. For example, all integer variables that we use in our program is an object of class int. Similarly all string variables are also object of class string.

11 STD || CHP: 3 || Computer Organization || Part-3 ||PORT AND INTERFACE
The Motherboard of a computer has many I/O sockets that are connected to the ports and interfaces found on the rear side of a computer . The external devices can be connected to the ports and interfaces. The various types of ports are given below
Serial Port: To connect the external devices, found in old computers.
Parallel Port: To connect the printers, found in old computers.
USB Ports: To connect external devices like cameras, scanners, mobile phones, external hard disks and printers to the computer.
USB 3.0 is the third major version of the Universal Serial Bus (USB) standard to connect computers with other electronic gadgets
. USB 3.0 can transfer data up to 5 Giga byte/second.
USB3.1 and USB 3.2 are also released.

A bus is a collection of wires used for communication between the internal components of a computer.
The word in the RAM has the same size (no. of bits) as the Memory Data Register (MDR). If the processor is an 8-bit processor like Intel 8085, its MDR and the word in the RAM both have 8 bits.
The read operation transfers the data(bits) from word to Memory Data Register. The write operation transfers the data(bits) from Memory Data Register to word.

Basics of Microprocessors
The CPU is the major component of a computer, which performs all tasks. This is realized by the microprocessor which is an Integrated Circuit. Microprocessors were first introduced in early 1970s. The first general purpose microprocessor, 4004 was developed by Intel Inc. The microprocessor is a programmable multipurpose silicon chip. It is driven by clock pulses. It accepts input as a binary data and after processing, it provides the output data as per the instructions stored in the memory. A block diagram of a microprocessor based system

Connecting PHP and MySQL
Data is important in computer and Internet related applications. Numerous growths of data need a secure and convenient environment to store and manipulate autonomously. All these features are available in Relational Database Management System (RDMS) such as MySQL, Oracle, IBM DB2, and Microsoft SQLSERVER etc. These databases are connected with Programing language and perform major operations like INSERT, SELECT, UPDATE and DELETE using Structured query language (SQL). The combination of PHP and MySQL has become very popular server side web scripting language in Internet.

11 STD || BOOTING & TYPES OF BOOTING || CHAP : 1 || COMPUTER
Booting of computer
An Operating system (OS) is a basic software that makes the computer to work. When a computer is switched on, there is no information in its RAM.At the same time, in ROM, the pre-written program called POST (Power on Self Test) will be executed first. This program checks if the devices like RAM, keyboard, etc., are connected properly and ready to operate. If these devices are ready, then the BIOS (Basic Input Output System) gets executed. This process is called Booting. Thereafter, a program called “Bootstrap Loader” transfers OS from hard disk into main memory. Now the OS gets loaded (Windows/Linux, etc.,) and will get executed. Booting process is of two types.
1) Cold Booting
2) Warm Booting

HTML Forms
Main objective of PHP and HTML form controls are to collect data from users. In the web development, user access website or web pages from remote client machine and feed the data to server. These data are collected via HTML form controls like textbox,
dropdown box and radio button etc., and sent to server using server side
programming like PHP.

Introduction
In python, a dictionary is a mixed collection of elements. Unlike other collection data types such as a list or tuple, the dictionary type stores a key along with its element. The keys in a Python dictionary is separated by a colon ( : ) while the commas work as a separator for the elements. The key value pairs are enclosed with curly braces { }.

Introduction
In python, a set is another type of collection data type. A Set is a mutable and an unordered collection of elements without duplicates. That means the elements within a set cannot be repeated. This feature used to include membership testing and eliminating duplicate elements .

Input Devices:
(1) Keyboard: Keyboard (wired / wireless, virtual) is the most common input device used today. The individual keys for letters, numbers and special characters are collectively known as character keys. This keyboard layout is derived from the keyboard of original typewriter. The data and instructions are given as input to the computer by typing on the keyboard. Apart from alphabet and numeric keys, it also has Function keys for performing different functions. There are different set of keys available in the keyboard such as character keys, modifier keys, system and GUI keys, enter and editing keys, function keys, navigation keys, numeric keypad and lock keys.

11 STD || PART-2 || Chp: 1 || Basic Components of Computer || Computer
Components of a Computer
The computer is the combination of hardware and
software. Hardware is the physical component of a computer like motherboard, memory devices, monitor, keyboard etc., while software is the set of programs or instructions. Both hardware and software together make the computer system to function Let us first have a look at the functional components of a computer. Every task given to a computer follows an Input- Process- Output Cycle (IPO cycle). It needs certain input, processes that input and produces the desired output. The input unit takes the input, the central processing unit does the processing of data and the output unit produces the output. The memory unit holds the data and instructions during the processing.

Introduction to Computers:
Computers are seen everywhere around us, in all spheres of life, in the field of education, research, travel and tourism, weather forecasting, social networking, e-commerce etc. Computers have now become an indispensable part of our lives. Computers have revolutionised our lives with their accuracy and speed of performing a job, it is truly remarkable. Today, no organisation can function without a computer. In fact, various organisations have become paperless. Computers have evolved over the years from a simple calculating device to high speed portable computers

Looping Structure:
Looping Structures are useful for writing iteration logics. It is the most important feature of many programming languages, including PHP. They are implemented using the following categories. for Loop structure and flow chart
●● for Loop
●● foreach Loop
●● While Loop
●● Do While Loop

12 STD || PART - 3 || CH-9 - Lists, Tuples, Sets and Dictionary || TUPLES ||
Advantages of Tuples over list
1. The elements of a list are changeable (mutable) whereas the elements of a tuple are unchangeable (immutable), this is the key difference between tuples and list.
2. The elements of a list are enclosed within square brackets. But, the elements of a tuple are enclosed by paranthesis.
3. Iterating tuples is faster than list.
