A university computer lab consisting of a local area network of desktop computers would be connected to the Internet via ________.

Question

BlackTom AI · Accepted Answer

This question asks about the technology used to connect a university computer lab LAN to the Internet.
Option 1: Dial up — This relies on traditional telephone lines and is extremely slow by modern standards, making it impractical for alab environment that typically requires higher bandwidth and reliability.
Option 2: Bluetooth — A short-range wireless technology intended for peripherals and small devices, not suitable for a campus lab network connecting to the Internet.
Option 3: DSL — While DSL uses telephone lines and provides broadband access, it is still a point-to-point service from a single user location and not the typical method by which a LAN of many desktops in a lab connects to the broader Internet through a central router or switch.
Option 4: Ethernet — The standard technology for local area networks, providing scalable wired connectivity within the lab. A lab’s LAN would use Ethernet switches and NICs, then connect to a gateway/router that connects to the Internet.
In summary, the lab would most plausibly be built on Ethernet for internal networking, with external Internet access provided through a gateway device. The other options do not align with the typical LAN-to-Internet architecture in a university lab.
