ADVANTAGES OF IOT

Access Information Communication Cost-Effective Automation (ACCA)

You can easily access data and information that is sitting far from your location, in real time.

Access information

Better communication is possible over a network of interconnected devices

Communication

Transferring data packets over a connected network save time and money

Cost-Effective

Is the need of the hour to manage everyday task without human intervention

Automation

Disadvantage of IOT

Privacy & Security Complexity Lesser Jobs Dependability (PCLD)

This is a major drawback of sharing information, as confidential information might not be safe & could be hacked by a third party easily

Privacy and security

A single loophole can affect the ENTIRE SYSTEM, (the most complicated aspect of IOT)

Complexity

With everyday task being automated, the need for human labor will reduce drastically

Lesser jobs

in 19-- , ____ created the first internet devices, a toaster that be turn on and off over the internet

1989, John Romkey

THE _____ term is coined by _____ executive director of the auto-ID center

1999, Internet of things, Kevin Ashton

2billion users

The IoT has the potential to connect 30X or as many ___ ‘objects’ to the internet

50 billion

is a term describing the acces of networking resources from a centralized third-party provider using wide area network (WAN)

Cloud networking

is a model that allow on-demand network access to shared computing resources, A model for managing, storing and processing data online via the internet

Cloud computing

4 characteristic of CLOUD COMPUTING

On-Demand Service Network Access Shared Resources Scalability (ONSS)

You use it when you needed

On-demand service

Use internet as medium

Network access

Resource are pooled together, it is used by multiple clients

shared resources

allows elasticity of resources

Scalability

Is an architecture that extends services offered by a cloud to edge devices such as routers, switches

Fog computing

is a relatively new term, which refers to data being processed at the edge of a network, instead doing all of the processing in a big central cloud

Edge computing

it is a technology that allows you to save files in storage, and then access those files via the cloud

Cloud storage

Many services today are called?

Cloud services

is a system of organizations, people, activities, information, and resources involved in moving a product or service from supplier to CUSTOMER

Supply chain

is defined as a process, which is used to examine big and small data sets with varying data properties to extract meaningful conclusion and actionable insights

blockchain technology

The _____ of blockchain technology is one of its main characteristics

Decentralization

blockchain employs cryptographic methods to guarantee the confidentiality and accuracy of transactions

Cryptographic security

are protocols employed by network users to come to a ____ regarding the legitimacy of transaction

Consensus Mechanisms

To validate transactions, miners compete by working through challenging mathematical puzzles. The first miner to solve the riddle gets to upload the new block to the blockchain

proof of work POW

the quantity of bitcoin that validators are ready to "stake" as collateral determines which of them gets to build new blocks, It requires less processing power than POW, it is also more energy efficient than POW

Proof of stake POS

A transaction is almost impossible to change or remove once it is registered on the blockchain and validated by the consensus process. The integrity of the transaction history kept on the blockchain is guaranteed by its _____?

Immutability

The blockchain makes transactions transparent by enabling anybody to see the complete history of transactions recorded there. By being_______, players are more likely to trust one another, which lessens the need for middlemen to confirm transactions.

Transparency

: Peer-to-peer transactions without the need for middlemen are made possible by blockchain technology, which powers cryptocurrencies like Ethereum and Bitcoin.

Cryptocurrencies

_______ are self-executing agreements that have the provisions of the contract explicitly encoded into the code. They streamline procedures and lessen the need for middlemen by automating and enforcing contractual agreements.

Smart Contracts

By doing away with middlemen and lowering transaction costs, blockchain can enable quicker and more affordable _____ payments.

Cross-Border Payments

By documenting each stage of the supply chain, from production to distribution, blockchain technology can offer end-to-end product _______. This promotes supply chain transparency, lowers counterfeiting, and guarantees product authenticity

Traceability

Voters can safely cast their ballots from any location in the world thanks to blockchain-enabled remote voting systems. By doing this, the security and integrity of the voting process can be preserved while simultaneously increasing voter accessibility and participation.

Remote Voting:

On the Ethereum blockchain, _____ is one of the most widely used programming languages for creating smart contracts. It is a contract-oriented, statically typed language with influences from Python, C++, and JavaScript. Decentralized finance (DeFi), decentralized autonomous organizations (DAOs), and token creation are just a few of the many uses for Solidity that make developing smart contracts easier.

Solidity

is an Ethereum smart contract language substitute that places an emphasis on auditability, security, and ease of use. Its syntax is similar to that of Python, and its goal is to reduce the risk of vulnerabilities while increasing developer accessibility to smart contract development.

Vyper

The smart contracts in Hyperledger, or chaincode, are written in Go (Golang) using the permissioned blockchain framework Hyperledger Fabric. Chaincode is run in a containerized environment after being deployed to the network.

Chaincode (Go)

One of the most popular blockchain protocols for creating decentralized applications is?

Ethereum

What is NFT?

Non-fungible Token
