Which statement describes a characteristic of cloud computing?
A A business can connect directly to the Internet without the use of an ISP
B Applications can be accessed over the Internet through a subscription
C Devices can connect to the Internet through existing electrical wiring
D investment in new infrastructure is required in order to access the cloud
The Correct Answer and Explanation is :
The correct answer is:
B. Applications can be accessed over the Internet through a subscription.
Explanation:
Cloud computing refers to the delivery of computing services, such as storage, processing power, applications, and databases, over the internet (the cloud), rather than relying on local servers or personal devices. A primary characteristic of cloud computing is the ability to access these services remotely via the internet.
Key Points About Cloud Computing:
- Access via Subscription:
Cloud services typically operate on a subscription model, meaning businesses or individuals can pay for access to applications and resources as needed. This allows users to avoid the upfront costs of buying software or hardware and instead pay for what they use on a periodic basis (monthly, annually, etc.). Popular examples of subscription-based cloud applications include software like Google Workspace, Microsoft 365, or Salesforce. - Scalability and Flexibility:
With cloud computing, users can scale their use of resources (such as storage or computing power) up or down based on current needs. This is a significant advantage over traditional models where businesses must invest in infrastructure that may not be fully utilized at all times. - Accessibility:
Cloud computing allows applications and data to be accessed from virtually any device with an internet connection, providing great flexibility and enabling remote work. This characteristic is one of the primary reasons for its rapid adoption.
Why the other options are incorrect:
- A. A business can connect directly to the Internet without the use of an ISP: This is not a characteristic of cloud computing. Internet service providers (ISPs) are still required to provide internet access to use cloud services.
- C. Devices can connect to the Internet through existing electrical wiring: This refers to technologies like powerline networking, not cloud computing.
- D. Investment in new infrastructure is required in order to access the cloud: One of the key benefits of cloud computing is that businesses do not need to invest in expensive infrastructure; they can rely on the resources offered by the cloud provider instead.
