Which device typically requests services or resources from the server?

The correct answer is a client. In networking, a client is any device or application that requests services or resources from a server. This relationship is fundamental in the client-server model, where clients initiate communication and request data or services that are provided by servers. Common examples of clients include web browsers, email applications, and any software that connects to a server to retrieve data or perform tasks.

Firewalls, hubs, and access points play different roles in a network infrastructure. A firewall is primarily a security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A hub functions as a basic networking device that connects multiple Ethernet devices, making them act as a single network segment, without processing or directing traffic. An access point is used to connect wireless devices to a wired network, enabling devices to connect to the network but not requesting resources or services in the manner a client does.
