Which of the following best describes an Internet Service Provider (ISP)?

An Internet Service Provider (ISP) is fundamentally defined as a company that provides internet access to users. ISPs facilitate the connection between users and the broader internet, allowing for the transmission of data and access to various online services. This includes a range of offerings such as broadband, dial-up, and fiber-optic services that meet the varying needs of individuals and businesses.

While other choices pertain to aspects of the internet ecosystem, they do not accurately capture the primary function of an ISP. Options related to software for browsing, securing personal data, or hardware components do not describe the role of ISPs in providing internet connectivity. Thus, understanding the core function of an ISP is crucial, as it is foundational to how users access and interact with the internet as a whole.
