What is the primary benefit of using Blockchain in web development?
A Simplified coding
B Increased storage capacity
C Enhanced data security
D Faster load times
Blockchain provides enhanced security by using decentralized, encrypted networks for data transactions. It ensures that data is immutable and secure, which is crucial in applications involving sensitive information or transactions.
How does AI improve web applications?
A By automating tasks
B By designing UI
C By managing databases
D By storing data
AI enhances web applications by automating processes like data analysis, personalization, and customer support (via chatbots). This allows for improved user experiences, efficiency, and more intelligent decision making in web apps.
What does IoT (Internet of Things) enable in web development?
A Better UI design
B Web security
C Faster server response
D Real time data exchange
IoT enables real time data exchange between physical devices and web applications. This allows web apps to interact with smart devices (e.g., sensors, cameras), leading to new functionalities in automation, monitoring, and remote control.
Which of the following is a major use case of blockchain in web development?
A Server hosting
B Decentralized applications
C Real time communication
D Image optimization
Blockchain is commonly used in decentralized applications (dApps), where control is distributed across multiple participants rather than relying on a single centralized authority. This provides better security, transparency, and control over user data.
How does AI powered web application enhance user experience?
A By providing real time feedback
B By simplifying design
C By handling backend requests
D By generating server side data
AI powered web applications improve user experience by providing real time feedback through features like personalized content recommendations, intelligent search, and chatbots that simulate human like interactions, enhancing overall usability.
What does the term “decentralized” mean in the context of blockchain and web development?
A Data storage on a single server
B Distributed control
C Higher encryption rates
D Centralized authority
In blockchain, “decentralized” means that control is distributed across multiple participants, rather than being concentrated in a single entity. This eliminates single points of failure, increases transparency, and ensures secure, tamper resistant data storage.
Which of the following is a typical use case of IoT in web applications?
A SEO optimization
B Content management
C E commerce transactions
D Smart home automation
IoT in web applications is commonly used in smart home automation. IoT devices like thermostats, cameras, and lights can be controlled and monitored via web apps, creating a seamless user experience for smart homes.
How does Blockchain help in ensuring transparency in web applications?
A By managing data privacy
B By using a centralized ledger
C By providing immutable records
D By reducing server load
Blockchain ensures transparency by creating immutable records that cannot be altered once added. Every transaction or action is recorded on the blockchain, and participants can view the history of all interactions, promoting accountability.
What is a key feature of AI in web applications?
A Automated content creation
B Better web hosting
C Real time data fetching
D Faster website rendering
AI in web applications can automate content creation, such as generating articles, product descriptions, and recommendations. This saves time and ensures that content is optimized and personalized for users based on their behavior.
Which of the following is an example of AI in web applications?
A Simple HTML formatting
B Database indexing
C Auto complete search suggestions
D Static page content
AI is used to provide auto complete suggestions in search boxes, which predict what the user is looking for. These suggestions are generated based on algorithms that analyze past search history and user behavior, improving the search experience.
What type of data can be exchanged in IoT based web applications?
A Predefined data
B Static content
C Sensory data
D Only text data
IoT based web applications often exchange sensory data from devices like temperature sensors, motion detectors, and cameras. This data is transmitted to web applications in real time to monitor, analyze, and automate processes in various domains like healthcare and smart cities.
Which of the following is an example of a decentralized application (dApp)?
A Amazon
B Google Docs
C Facebook
D Ethereum
Ethereum is a blockchain based decentralized application (dApp) platform. It allows developers to build smart contracts and decentralized applications, enabling peer to peer transactions without relying on a central authority or intermediary.
How does Web 3.0 differ from previous versions of the web?
A Focus on text based content
B Increased server control
C Decentralization and privacy
D Centralized platforms
Web 3.0 is characterized by decentralization, where control is distributed among users rather than centralized entities. It focuses on data privacy, user control, and the integration of blockchain technologies for secure interactions.
Which of the following is true about Web 3.0 technologies like blockchain?
A They offer increased transparency
B They rely on centralized systems
C They use traditional databases
D They prioritize speed over security
Web 3.0 technologies like blockchain offer increased transparency by allowing all participants to view and verify transactions in a decentralized ledger. This ensures that the data is auditable and tamper resistant.
Which technology allows web applications to control physical devices in IoT systems?
A Cloud databases
B Web APIs
C JavaScript
D WebSockets
Web APIs (Application Programming Interfaces) allow web applications to communicate with and control physical devices in IoT systems. They enable real time interaction between the web application and the devices, allowing for remote control and monitoring.
