Despite its many benefits, blockchain technology is still in its early stages of development and adoption, and there
are several challenges that must be overcome, including scalability, regulatory compliance, and interoperability with
existing systems. However, as the technology continues to mature, it is expected to have a significant impact on a wide
range of industries and applications.
Blockchain technology is a decentralized, distributed ledger that records transactions on multiple computers,
providing a secure and transparent way to store and transfer data.
State whether the following statements are True or False.
1. Blockchain can be used for the exchange of bitcoins.
2. The blockchain is controlled by a central authority.
Let's Summarise
Ø Artificial intelligence (AI) is a branch of computer science that aims to make machines so intelligent that they
can perform tasks that typically require human intelligence, such as learning, reasoning, problem-solving,
perception, and natural language understanding.
Ø Machine learning (ML) is a subdomain of artificial intelligence (AI) that involves the use of statistical and
specialized algorithms to enable computer systems to learn and improve from experience without being
explicitly programmed.
Ø There are three main approaches to machine learning: supervised learning, unsupervised learning, and
reinforcement learning.
Ø Natural Language Processing (NLP) is a subfield of artificial intelligence (AI) that focuses on enabling machines
to understand, interpret, and generate human language.
Ø NLP techniques include text analysis, sentiment analysis, speech recognition, and machine translation.
Ø The Natural Language Toolkit (NLTK) is a popular Python library used for working with human language data.
Ø Immersive experience refers to a type of technology that creates a sense of immersion or presence in a
simulated (virtual) environment.
Ø Virtual reality creates a completely immersive experience by replacing the user’s physical reality with a
simulated environment.
Ø Augmented reality overlays digital information onto the real world, creating a hybrid experience that blends
the physical and digital worlds.
Ø AR can be used for applications such as marketing, advertising, education, and navigation.
Ø Robotics involves the design, construction, operation, and use of robots.
Ø Autonomous robots are designed to operate independently without human intervention.
Ø AI algorithms are used to enable autonomous robots to learn from their environment and adapt to new
situations.
Ø Big data refers to extremely large and complex datasets that cannot be easily managed, processed, and
analyzed using traditional data processing tools and techniques.
