1. Computer vision is the ability of computers to interpret and understand visual information from the world around us. Two applications of computer vision are: Self-driving cars, and Google Lens.
2. Computer vision generally works in three basic steps:
Acquiring the image/video from a camera
Processing the image
Understanding the image
3. AI plays a crucial role in computer vision by enabling computers to see and analyse the visual data. AI algorithms provide the computational power needed to analyse large amount of image and video data and extract meaningful information from it.
4. The cameras installed in self-driving cars capture videos from different angles around the car. These videos are fed into computer vision software, which then processes them in real-time, which detects road conditions, like roadblocks, road constructions, speed breaker, etc., reads traffic signs, and detects other cars and objects like pedestrians. The car then moves based on the information generated by the computer vision algorithm, which will avoid hitting obstacles and safely drive passengers to their destination.
5. Two applications of Google Lens are:
Translation: Google Lens is used to translate text to the language of your choice in real-time.
Search your Surroundings: Google Lens is used to recognise the objects in your environment.

Kritika should use ‘\t’ escape sequence as a separator with the print() function.
E. Answer the following questions.
1. Three features of Python language are:
It is an easy to learn general-purpose high-level programming language.
It is a platform independent programming language, which means it can be used on any machine and operating system.
Python needs to use only a few lines of code to perform complex tasks.
2. Named storage locations in the computer memory, which are used to store data, are called variables. A variable can store only one data value at a time.
3. Integer contains positive or negative whole numbers (without fraction or decimal). For example, 15, –7, 314, etc. On the other hand, float is a real number with floating point representation. It is specified by a decimal point. For example, 3.14, –48.6, 18.0, etc.
4. The input () function is used to accept the value for a variable from the user. It takes only the string argument.

E. Answer the following questions.
1. Two features of Excel are:
It allows us to perform powerful calculation using built-in functions.
It allows us to enhance the appearance of data in a worksheet by applying various formatting features.
2. A workbook is the entire file, containing multiple worksheets. A worksheet is a single sheet within the workbook, where data is entered and manipulated.
3. A cell is the basic unit of a worksheet in Excel. It is the intersection of a row and a column and can contain data such as text, numbers, or formulas.
4. Types of data that can be entered in a cell include text, numbers, dates, and formulas. 5. A formula is an expression that performs calculations on values in a worksheet. It begins
with an equal (=) sign and can include mathematical operations, functions, and cell references.

Type the new content directly in the cell to replace.
Double-click on the cell containing the data, make the necessary changes, and press Enter.
2. To select a range of non-adjacent columns, hold down the Ctrl key and click on the column headers of the desired columns.
3. Auto Fill is the easiest method to fill the consecutive data items automatically in the cells of a worksheet.
4. Flash Fill is a time-saving feature, which identifies the pattern in data that you have used in a worksheet and then fills the remaining series accordingly.
5. The Undo command (Ctrl + Z) reverses the last action, while the Redo command (Ctrl + Y) restores the action that was undone.
