Ans: True
Q.4) Explain the following
1) Give some applications of IoT.
Ans: Applications of IoT:
- Smart Lighting: Illumination of light is controlled on the basis of day light.
- Smart Thermostat: Allows users to schedule, monitor and remotely control home temperatures.
- Smart Locks and Garage Door Openers: Password based or facial recognition based doors and locks.
- Smart Security Camera: Security cameras that can identify known and unknown persons and raise alarm in case of security threat.
- Smart Traffic Signals: Signals that can adjust their timing to accommodate commutes and holiday traffic and keep cars moving.
2) Explain in detail about cloud computing.
Ans: Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of computing resources like networks, servers, storage, applications and services with minimal service provider interaction.
There are three basic types of deployment of cloud computing:
- Public Cloud: In public cloud, all the services and supporting infrastructure are managed off-site over the internet and shared across multiple users.
Examples: Amazon AWS, Microsoft Azure, Google Cloud Platform. - Private Cloud: As the name suggests, private cloud provides IT services through the internet or a private network to selected users rather than the general public.
- Hybrid Cloud: Hybrid cloud environment combines both public and private cloud elements.
3) Explain models of cloud computing.
Ans: Models of Cloud Computing:
There are three primary service models of cloud computing:
- Infrastructure as a Service (IaaS): IaaS gives users access to storage, networking, servers and other computing resources via the cloud.
- Platform as a Service (PaaS): A service provider offers access to a cloud-based environment in which users can develop, manage and deliver applications.
- Software as a Service (SaaS): A service provider delivers software and applications through the internet. Users do not install applications on their local devices.
4) Give brief idea about AI.
Ans: Artificial Intelligence (AI) is an area of computer science that emphasizes the creation of intelligent machines that work and react like humans.
AI is different from robotics but related to some extent in which machines sense their environment, perform calculations and do physical tasks either by themselves or under the direction of people.
AI has some sub-fields like:
- Machine Learning
- Neural Networks
- Deep Learning
- Cognitive Computing
5) Explain the concept of 5G.
Ans:
- 5G is the 5th generation of cellular network technology.
- 5G is the next generation of wireless communications.
- It is expected to provide internet connections that are multiple times faster than 4G LTE (Long Term Evolution).
- 5G technology may use a variety of spectrum bands, including millimeter wave (mm wave) radio spectrum, which can carry very large amounts of data over short distances.
- The drawback of higher frequencies is that they are more easily obstructed by walls of buildings, trees and other foliage, and even changes in weather.
