BLOCKCHAIN
Blockchain refers to the system of recording information which makes it difficult or impossible to
change, hack, or cheat the system. Every business runs on information and blockchain is a shared
ledger on which we record the transactions and track assets (tangible or intangible) in a business
network. Tangible assets include houses, cars, cash, lands, etc. and non-tangible assets include
intellectual property, patents, copyrights, branding, etc.
It is a digital ledger of transactions that is duplicated and distributed across the entire network
of computers on the blockchain. Each block in a chain may contain the record of the number of
transactions made and the occurrence of new transactions. This record of every transaction is
updated and added to the participant’s ledger. Anything that carries value can be recorded and
tracked and can be traded on a blockchain network.
ARTIFICIAL INTELLIGENCE
You have already read about artificial intelligence in earlier classes. AI is the branch of computer
science that aims at creating expert and intelligent computer systems which simulate certain
human qualities such as, learning, reasoning, communicating, seeing, hearing, and sensation.
So, AI is used to create intelligent machines that help us. AI is a part of almost everything we use
today such as smartphones, cars and banks. Some main areas of application of AI are:
Expert System: It can be defined as a communicating
User
computer program that can solve problems which Interface
would otherwise require human assistance. These User (not
programs replicate the reasoning process of experts Inference an expert)
engine
in certain areas. For example, PROSPECTOR was the
first expert system that analysed geological data to Knowledge
base
identify and locate mineral deposits. Human Knowledge
expert engineer
Expert system
Natural Language Processing: It is the study of methods by which
computers can recognize and understand spoken or written human
language. Speech recognition software are an example of NLP
Natural language processing where computers translate spoken speech into text.
Intelligent Agents: It is a type of computer program that has
built-in intelligence which keeps a check on the work patterns,
asks questions and performs tasks on the behalf of the user. The
simplest example of intelligent agents is surfing the Internet. What
happens when we search for something on the Internet?
