Understanding Cloud Services
Cloud services are computing resources (like storage, processing power, or software) that are delivered over the internet on demand. Instead of being stored or run on your local computer or server, they reside in data centers managed by a third party and are accessed remotely, usually through a web browser or an application that connects to the internet.
Let's examine each option provided in the question to determine if it fits the definition of a Cloud Service:
Analyzing Each Option: Is it a Cloud Service?
(A) Google Drive
Google Drive is a prime example of a cloud storage service. It allows users to store files and folders in the cloud (on Google's servers), synchronize them across multiple devices, and share them with others. You access your files via the internet using a web browser or a dedicated application. Therefore, Google Drive is a Cloud Service.
(B) MeghRaj
MeghRaj is the name given to the Government of India's Cloud initiative. It is a platform that aims to accelerate the delivery of e-services in the country by providing cloud infrastructure and services to government departments. It is essentially a government-specific cloud platform, offering Cloud Services. Therefore, MeghRaj is a Cloud Service.
(C) Dropbox
Similar to Google Drive, Dropbox is a popular cloud storage service. It provides users with online space to store files, access them from different devices, and collaborate with others. Files are synced through the internet to Dropbox's servers. Therefore, Dropbox is a Cloud Service.
(D) Windows Explorer
Windows Explorer (now called File Explorer in newer Windows versions) is the built-in file manager application for the Microsoft Windows operating system. Its primary function is to navigate and manage files and folders stored locally on the computer's hard drives, connected external drives, or network drives. While it can interface with cloud storage services (like Microsoft OneDrive), Windows Explorer itself is a local application for managing local files. It does not provide computing resources or storage over the internet as its core function.
Therefore, Windows Explorer is not a Cloud Service.
Identifying What is Not a Cloud Service
Based on the analysis:
- Google Drive is a Cloud Service.
- MeghRaj is a Cloud Service.
- Dropbox is a Cloud Service.
- Windows Explorer is NOT a Cloud Service.
The question asks which of the following is/are not an example(s) of a Cloud Service. Only Windows Explorer fits this description among the given options.
Let's look at the provided options for the answer:
- B Only: Incorrect, MeghRaj is a Cloud Service.
- D Only: Correct, only Windows Explorer is not a Cloud Service among the choices.
- C and D Only: Incorrect, Dropbox is a Cloud Service.
- A, B and D Only: Incorrect, Google Drive and MeghRaj are Cloud Services.
The option that correctly identifies what is/are not an example(s) of a Cloud Service is D Only.
| Option | Is it a Cloud Service? | Reason |
|---|---|---|
| (A) Google Drive | Yes | Online storage accessible via internet. |
| (B) MeghRaj | Yes | Government Cloud initiative/platform. |
| (C) Dropbox | Yes | Online storage accessible via internet. |
| (D) Windows Explorer | No | Local file manager application. |
Revision Table: Cloud Services Key Concepts
| Concept | Description | Examples |
|---|---|---|
| Cloud Computing | Delivery of computing services (servers, storage, databases, networking, software, analytics, intelligence, etc.) over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. | Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP) |
| Cloud Service | A specific resource or application provided via cloud computing infrastructure. | SaaS (Software as a Service), PaaS (Platform as a Service), IaaS (Infrastructure as a Service) |
| Cloud Storage | A model of computer data storage in which digital data is stored in logical pools, said to be on "the cloud". The physical storage spans multiple servers, and the physical environment is typically owned and managed by a hosting company. | Google Drive, Dropbox, OneDrive, iCloud |
| Local File System / Manager | A method for storing and organizing computer files and the data they contain to make it easy to find and access them. A manager is an application that provides a user interface to manage files and folders on a local storage device. | Windows Explorer/File Explorer, macOS Finder, Linux File Manager |
Additional Information: Types of Cloud Services
Cloud services are typically categorized into three main types:
- Infrastructure as a Service (IaaS): This provides fundamental computing resources like servers, storage, and networks over the internet. Users manage the operating system and applications.
- Platform as a Service (PaaS): This provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.
- Software as a Service (SaaS): This provides software applications over the internet on a subscription basis. Users access the software via a web browser or client application without needing to install or manage it locally. Google Drive and Dropbox are examples of SaaS.
MeghRaj, being a government initiative providing cloud infrastructure and services, would encompass elements of IaaS and PaaS, enabling various government departments to build and deploy e-services (which might be delivered as SaaS to citizens).
Windows Explorer, being a core component of a local operating system for managing local files, does not fit into any of these cloud service categories.

A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
Consider the following statements:
1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.

One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
