Introduction to Files and Folders When we go to school, we usually take a tiffin box with us. The tiffin box contains our food.

A tiffin box can contain a variety of foods. Similarly, if we want to keep some information on the computer, files help us store it.

A file is a collection of information.

It is stored on a computer. Files can hold text, pictures, songs, videos, and much more.

Now, we know that files store information. Let us take the example of the tiffin box. We keep our tiffin box in our school bag. In the same way, we can keep our files on our computer in folders.

A folder is a container that can store files.

Folders can be used to organise files and make them easier to find. They act as holders where you can group similar files together.

MS Paint There are many beautiful things around us. You might like watching flowers, Sun, mountains, and many more things that surround you. The fun part is that you can draw all these on paper or a chart with the help of a pencil, crayons, etc.

We can also make all these beautiful things on a computer without using paper, colour, or pencil.

For this, you can use a program called MS Paint or simply Paint.

MS Paint, a short form for Microsoft Paint, is like a colouring book on the computer, where you can draw and colour pictures using different tools and colours.

It allows users to create and edit simple drawings, digital art, and images using various tools like brushes, shapes, and colour palettes.

How would you do this in Paint?

In Paint, there is a Select tool that helps you select a particular part of your drawing to make changes.

There are two main types of selection options in Paint: 1. Rectangular selection 2. Free-form selection

Introduction to Text Editing In the previous chapter, you created a document on Waste Management. You also learnt how to create, save, search, open, and share a document. In this chapter, you will learn how to edit the text in documents.

Text editing in Google Docs is the process of making changes to the text to improve its clarity and accuracy. It can also include copying, deleting, and moving the text.

Editing Text Once you type the text in any document, you may want to make some changes to that text. For example, if you want to add some text about the different types of waste in the Waste Management document, we can do it by following the steps given below: 1. Place your cursor where you want to add the text. Press the Enter key.

Selecting Text After typing the text, you can perform many operations on it, like deleting the text, duplicating the text, etc. For this, you need to first select the text. You can select a letter, a word, a block of text, a paragraph, or the complete document.

Selecting text using a mouse: 1. A word: Double-click the word.

2. A paragraph: Triple-click anywhere on the paragraph.

3. A block of text: Click on the beginning of the first letter of the text, drag over the text, and then release the mouse button.

Copying and Pasting the Text If you have a word that you want to use many times in your document, then instead of typing it again and again, you can just copy and paste it wherever you need it.

In this way, you save time and do not have to keep typing the same word over and over.

Copying text means duplicating the selected text and making it available for another location.

Imagine you want to write the full form of “3 Rs” in the last line. Instead of typing it again, you can just copy it from the top part of the document and paste it at the end.

Pasting means putting something you copied from one place into another place in the document.

Steps to Copy the Text You can copy the text with a keyboard or a mouse. Using the keyboard, press the ‘Ctrl’ and ‘C’ keys together. Steps to copy the text using a mouse are given below: 1 1. Select the text that you want to copy.

Moving Text While editing text, you might realise that some text is in the wrong place and needs to be moved elsewhere.

Moving text means removing it from its original position and placing it at some other position in the document.

We can move text using the Cut and Paste commands. The Cut command removes the text from its original position.

Let us see how we can move the text.

In the above document, for example, you want to change the position of the ‘Hospital wastes’ section from its original position and place it after ‘Dry and recyclable wastes’.

Steps to move the text are given below: 1. Triple-click on the ‘Hospital wastes’ line to select the paragraph.

The Delete key is used to erase a word, line, or paragraph that you want to remove from your document.

For example, in our document, we want to delete “it’s” and replace it with “it is”. To do that, we will follow the steps below: 1. Select the text.

In this chapter, we will get on with the exciting adventures with AI (Artificial Intelligence) friends. AI is like having a friend who can help you with various tasks and even play games with you. Let’s start by understanding what AI is and exploring the adventures associated with it.

What is AI? AI stands for Artificial Intelligence, which means the machines that can think and learn like humans.

“Artificial Intelligence is like having a smart friend in the form of a computer or a robot. It is a special kind of computer program that can think and learn to do different tasks, just like you learn new things in school.”

For example, voice assistants like Siri and Alexa can answer your questions, play music, and help with tasks.

AI in Daily Life AI is used in many ways to help people in their daily lives. Some of the ways we use AI include: 1. Answering Questions: AI can be like a smart robot that can answer questions when we talk to it, like asking about the weather or telling us a joke.

2. Playing Games: AI can be our playmate in video games and board games, making games more fun and challenging.

3. Self-Driving Cars: Some cars make use of AI to automate driving and make decisions to keep us safe on the road.

4. Suggesting Movies and Music: AI can recommend movies or music based on what we have enjoyed before.

5. Learning and Drawing: AI can learn how to draw pictures or even help us learn new things.

AI Gadgets AI appliances are like smart helpers in our homes. They are special machines that can think and make our lives easier.

AI in Appliances 1. Smart Refrigerator: This magical refrigerator can keep track of the food inside and tell you when you are running out of your favourite snacks. It can even suggest yummy recipes to cook your favourite dishes.

2. Robot Vacuum: Robotic vacuums help you clean; they can zoom around your home all by themselves. You can even give it a name.

3. Voice Assistant: You can talk to a friendly AI on your tablet or smart speaker. It can answer questions, play your favourite songs, and tell you jokes.
