TERMINAL EXERCISE 

1. What is cloud computing? 

Ans: Cloud computing is a technology that provides computing services such as servers, storage, software, and applications over the Internet on demand. 

2. What is virtualization and how does it improve resource utilization? 

Ans: Virtualization is a technology that allows multiple virtual machines to run on a single physical computer using software called a hypervisor. Each virtual machine works like an independent system.

It improves resource utilization by sharing CPU, memory, and storage among multiple systems, reducing idle hardware, lowering costs, and allowing resources to be allocated as needed.

3. How can we develop eco-friendly environment for computing? 

Ans: An eco-friendly computing environment can be developed by using energy-efficient devices, adopting virtualization and cloud computing, switching off systems when not in use, using renewable energy, and recycling e-waste. These steps reduce energy consumption and protect the environment. 

4. What is mobile computing and what are its applications? 

Ans: Mobile computing is an umbrella term used for describing the technologies that enable people to access network services any place, any time, and anywhere. It is an extension of mobile voice communication technology which is capable of sending and receiving data across the cellular network.

Applications of mobile computing:

(i) Communication – calls, messaging, email, and video conferencing.

(ii) Education – online classes, e-learning apps.

(iii) Business – mobile banking, online shopping, remote work.

(iv) Healthcare – telemedicine and health monitoring apps.

(v) Navigation & travel – GPS, maps, ride-sharing services.

5. What is grid computing and in which environment it is found very useful?

Ans: Grid computing is a computing system where many computers work together to perform large tasks by sharing resources. It is most useful in scientific and research environments, such as weather forecasting, space research, and data analysis.
