Which is an example of a basic network service?

• A. IP address
• B. Modem
• C. Secure web browsing
• D. 2.4GHz

Answer: (C)

Network services are the programs and protocols that allow devices to perform tasks over a network. Secure web browsing is a service because it enables you to access and view web content over the internet, typically using HTTPS which adds encryption via TLS to HTTP so the connection is private and secure. This is a basic, user-facing network capability that people rely on every day, making it a classic example of a network service. The other items aren’t services: an IP address is just a numeric identifier for a device, a modem is hardware that connects networks, and 2.4GHz is a frequency band used by wireless signals, not a service offered over the network.
