v Uploading and downloading large volumes of data can be time-consuming.  

v Switching providers or platforms can be complex and costly.  

v Cloud services can experience outages, leading to disruptions in business operations.

 

 

 

Types of cloud computing services

v Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet like processing, storage, and networking. E.g. Amazon Web Services (AWS) EC2, Microsoft Azure Virtual Machines and Google Cloud Compute Engine.

v Software as a Service (SaaS): Delivers software applications over the internet. Services like Gmail, Google Drive, Office 365, Dropbox

v Platform as a Service (PaaS): Offers a platform for developers to build, run and manage applications over the internet. E.g. Microsoft Azure App Service, Google App Engine, Heroku etc.

 

Types of Cloud

v Public cloud - A public cloud is a service that provides computing resources over the internet. Example: Google Drive for storing files online.

v Private cloud - A private cloud is a computing service used by single organization. Example: A bank's own secure system for storing customer data.

v Hybrid cloud - A hybrid cloud combines public and private clouds.

Example: A company using public cloud for email and private cloud for sensitive financial data.

"Al is for the aid of people not their against. Explain.

AI is created to help people by making tasks easier and improving people’s lives. For example, AI can assist doctors in diagnosing diseases quickly, suggest products online, and provide support through chatbots. Its main goal is to support and enhance human activities, not to act against them.

 

"Artificial Intelligence is threat to humans". Give your opinion.

Ans: "Artificial Intelligence can be a threat if not managed properly, as it might lead to job loss, privacy issues, or misuse. Poorly managed AI systems can make unfair decisions or be easily hacked, leading to security problems and biased results. AI handles routine tasks well but cannot create original ideas or solutions like humans can.
