Right Answer:
5G enhances augmented reality (AR) and virtual reality (VR) by providing high-speed data transfer, low latency, and the ability to connect many devices simultaneously. This allows for smoother, more immersive experiences, real-time interactions, and seamless streaming of high-quality content in AR and VR applications.

Right Answer:
5G enhances IoT connectivity by providing higher data speeds, lower latency, and greater capacity, allowing more devices to connect simultaneously and communicate more efficiently.

Right Answer:
Global 5G adoption is expected to continue growing rapidly, with widespread deployment anticipated by 2025, and significant coverage expected by 2030.

Right Answer:
5G is the fifth generation of mobile network technology, designed to provide faster speeds, lower latency, and greater capacity compared to previous generations like 4G. It enables more devices to connect simultaneously and supports advanced applications such as IoT, augmented reality, and autonomous vehicles.

Right Answer:
Small cells in 5G are low-power wireless access points that cover small areas, enhancing network capacity and coverage. They are important because they help improve data speeds, reduce latency, and support a higher number of connected devices, especially in dense urban environments.

Right Answer:
API authentication is the process of verifying the identity of a user or application trying to access an API. Common methods include:

1. **API Keys**: Unique keys provided to users to access the API.
2. **Basic Authentication**: Uses a username and password encoded in Base64.
3. **OAuth**: A token-based authentication method that allows users to grant limited access to their resources without sharing credentials.
4. **JWT (JSON Web Tokens)**: A compact, URL-safe means of representing claims to be transferred between two parties, often used for stateless authentication.
5. **HMAC (Hash-based Message Authentication Code)**: Uses a secret key to create a hash of the request, ensuring data integrity and authenticity.

Right Answer:
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. In APIs, JSON is commonly used to format data exchanged between a client and a server, allowing for structured data representation in requests and responses.

Right Answer:
API documentation is a technical manual that explains how to use an API, including its endpoints, request and response formats, authentication methods, and examples. It is necessary because it helps developers understand how to integrate and interact with the API effectively, ensuring proper usage and reducing errors.

Right Answer:
A web service is a standardized way of allowing different applications to communicate over the internet using protocols like HTTP. It provides a method for applications to exchange data and perform operations. An API (Application Programming Interface) is a set of rules and tools that allows different software applications to interact with each other. A web service is a type of API that specifically uses web protocols to enable this interaction.

Right Answer:
CORS, or Cross-Origin Resource Sharing, is a security feature implemented by web browsers that allows or restricts web applications from making requests to a domain different from the one that served the web page. It affects API development by requiring developers to configure their APIs to specify which origins are allowed to access their resources, ensuring that only trusted domains can interact with the API.

Right Answer:
I am [Your Name], and I have a background in [Your Field/Industry]. I have developed skills in [Key Skills Relevant to the Job, e.g., project management, software development, data analysis], and I am knowledgeable in [Relevant Technologies or Concepts]. I am passionate about [Your Interests Related to the Job] and continuously seek to improve my skills through [Learning Methods, e.g., courses, workshops, hands-on experience].

1. Normal Distribution
2. Binomial Distribution
3. Poisson Distribution
4. Uniform Distribution
5. Exponential Distribution
6. Log-Normal Distribution
7. Geometric Distribution
8. Beta Distribution
9. Chi-Squared Distribution
10. Student's t-Distribution

Right Answer:
To handle missing data in a dataset, you can use the following methods:

1. **Remove Rows/Columns**: Delete rows or columns with missing values if they are not significant.
2. **Imputation**: Fill in missing values using techniques like mean, median, mode, or more advanced methods like KNN or regression.
3. **Flagging**: Create a new column to indicate missing values for analysis.
4. **Predictive Modeling**: Use algorithms to predict and fill in missing values based on other data.
5. **Leave as Is**: In some cases, you may choose to leave missing values if they are meaningful for analysis.

Right Answer:
Outliers are data points that significantly differ from the rest of the dataset. They can skew results and affect statistical analyses. To handle outliers, you can:

1. Identify them using methods like the IQR (Interquartile Range) or Z-scores.
2. Remove them if they are errors or irrelevant.
3. Transform them using techniques like log transformation.
4. Use robust statistical methods that are less affected by outliers.
5. Analyze them separately if they provide valuable insights.

Right Answer:
Correlation is a statistical measure that indicates the extent to which two variables fluctuate together, while causation implies that one variable directly affects or causes a change in another variable.

Right Answer:
Lifecycle methods in mobile app development are functions that manage the states of an application as it runs. They include methods for when the app is created, started, resumed, paused, stopped, and destroyed. These methods help developers control the app's behavior during transitions between these states, ensuring proper resource management and user experience.

Right Answer:
I use tools like Android Studio's Logcat, Xcode's debugger, Chrome DevTools for web views, and third-party tools like Flipper or Firebase Crashlytics for debugging mobile apps.

Right Answer:
APIs (Application Programming Interfaces) in mobile app development allow different software applications to communicate with each other, enabling the app to access external services, data, and functionalities, such as databases, web services, and third-party integrations, which enhances the app's capabilities and user experience.

Right Answer:
Some popular mobile development frameworks are:

1. React Native
2. Flutter
3. Xamarin
