3. Answer the following. 1. Three advantages of Google Drive are: Cloud Storage*: It provides secure cloud storage for files, making them accessible from any device with an internet connection. Collaboration*: Users can easily share files and folders, allowing multiple people to work on documents simultaneously in real-time. Automatic Backup*: Files are automatically backed up to the cloud, reducing the risk of data loss due to device failure. 2. Google Photos is used for storing, organizing, and sharing photos and videos. It offers unlimited storage (for certain quality settings), automatic backups, and AI-powered features for searching and categorizing images. 3. Two-factor authentication (2FA) is a security process that requires two different methods of verification to confirm a user's identity. It adds an extra layer of security beyond just a password, often involving something you know (password) and something you have (e.g., a code from your phone). 4. Khalil Shreateh is a Palestinian security researcher. He is popular for discovering a critical vulnerability in Facebook in 2013 that allowed him to post on any user's timeline, including Mark Zuckerberg's, even after Facebook's security team initially dismissed his reports. 5. An Event Handler is a block of code or a function that is executed when a specific event occurs. These events can be user actions (like a mouse click or key press) or system-generated events (like a page loading or an error occurring). 6. The difference between the '=' and '==' operators is: The '=' operator is an assignment operator*. It assigns the value on the right side to the variable on the left side. For example, x = 5 assigns the value 5 to the variable x. The '==' operator is a comparison operator*. It checks if the values of two operands are equal. It returns true if they are equal and false otherwise. For example, x == 5 checks if the value of x is equal to 5. 4. Write short notes. 1. Google Calendar is a time-management and scheduling web service developed by Google. It allows users to create and edit events, set reminders, and share calendars with others. It integrates with other Google services like Gmail and Google Meet. 2. Grey Hat Hackers are computer security hackers who operate in an ethical and legal grey area. They may find vulnerabilities in systems without authorization, but unlike black hat hackers, they typically do not exploit them for personal gain or malicious intent. Instead, they often disclose the vulnerabilities to the owner, sometimes expecting a reward. 3. The alert() method is a built-in JavaScript function that displays an alert box with a specified message and an "OK" button. It is commonly used to provide information or warnings to the user, or to debug code by displaying variable values.
