Cloud technologies
What is the difference between public cloud, private cloud, and hybrid cloud?
Public cloud services are provided by third-party providers over the internet. Private cloud infrastructure is dedicated to a single organization, often on-premises. Hybrid cloud combines both public and private clouds, allowing data and applications to move seamlessly between them.
What is the difference between raster graphics and vector graphics?
Raster graphics are composed of pixels and are resolution-dependent. Vector graphics are defined by mathematical equations and are resolution-independent.
What is the purpose of the OSI model, and how does it help in understanding network communication?
The OSI model provides a framework for understanding network communication by dividing networking tasks into seven layers. It helps standardize communication protocols.
What are the main types of machine learning algorithms (supervised, unsupervised, and reinforcement learning)?
The main types are:
What is a Database?
A database is an organized collection of related data stored and structured to serve a specific purpose (e.g., a library catalog).
How does data encryption work in cloud storage services?
Data is encrypted at rest and in transit to ensure security. Encryption keys are managed by the cloud provider or the user.
How does anti-aliasing improve the visual quality of computer-generated images?
Anti-aliasing reduces jagged edges by smoothing pixel transitions, resulting in better image quality.
Compare and contrast TCP/IP and OSI models.
Both models describe network protocols, but they differ in layer count and specifics. TCP/IP is widely used in practice, while OSI is more theoretical.
What do you understand by ‘Artificial Intelligence’?
Artificial Intelligence (AI) refers to computer science technology that emphasizes creating intelligent machines capable of mimicking human behavior. These machines can think, make decisions, and perform tasks without explicit pre-programming.
Define DBMS (Database Management System).
DBMS allows users to organize, store, and retrieve data efficiently. Examples include MySQL, Oracle, and Sybase.
What is the role of a load balancer in a cloud-based application?
A load balancer distributes incoming traffic across multiple servers to improve performance and reliability.
Describe the process of rendering a 3D scene in computer graphics.
Rendering converts 3D models into 2D images using lighting, shading, and camera parameters.
How does DNS (Domain Name System) work to resolve domain names to IP addresses?
DNS resolves domain names (e.g., www.example.com) to IP addresses, allowing users to access websites using human-readable names.
Why do we need Artificial Intelligence?
AI helps solve complex problems, automates routine tasks, saves manpower, and enhances various applications in today’s world
What is RDBMS (Relational Database Management System)?
RDBMS stores data in separate tables with common columns. SQL is used to access data from relational databases.
Explain the concept of “elastic scaling” in cloud computing.
Elastic scaling automatically adjusts resources (e.g., compute, storage) based on demand. It scales up during high traffic and down during low usage.
What are texture maps, and how are they used in 3D graphics?
Texture maps are images applied to 3D surfaces to add detail and realism. They define surface properties like color, roughness, and bumpiness.
What do businesses use to back up documents on a regular basis?
Businesses use backup solutions (e.g., cloud storage, external drives) to regularly back up important documents.
Give some real-world applications of AI:
What are the advantages of DBMS?
What are serverless components in cloud computing?
Serverless components allow developers to build and deploy applications without managing servers. Examples include AWS Lambda, Azure Functions, and Google Cloud Functions.
Explain the concept of ray tracing and its significance in realistic rendering.
Ray tracing simulates realistic lighting and reflections in computer-generated images. It produces high-quality, photorealistic renderings.
What type of “computer” is connected to the network through printers, scanners, or fax machines?
Peripherals such as printers, scanners, and fax machines are connected to the network through print servers.
How does AI differ from Machine Learning (ML) and Deep Learning (DL)?
What is data redundancy?
Data redundancy occurs when the same data is duplicated in multiple locations within a database, leading to wasted storage space and compromised integrity.
