Which term best describes a device that allows access to the Internet for browsing?

The term that best describes a device that allows access to the Internet for browsing is a browser. A browser is a software application that enables users to access, retrieve, and view information on the World Wide Web. It interprets HTML documents, displays multimedia content, and allows for navigation among web pages through hyperlinks, making it essential for online browsing.

In contrast, a router is a networking device that connects multiple networks and directs internet traffic, but it does not enable browsing itself. A switch operates within a local area network (LAN) to connect devices and manage the data packets within that network but does not facilitate internet access. Lastly, a firewall is a security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules, which protects the network rather than enabling browsing.

Thus, while other devices play crucial roles in networking and protecting data, the browser is specifically designed for navigating the internet and browsing content, making it the correct choice.
