Can I use Ethernet without a modem for internet access?
While it’s technically possible to use Ethernet without a modem in certain situations, it’s not a common or recommended setup for internet access. Ethernet is a type of local area network (LAN) technology that allows devices to communicate with each other, but it doesn’t provide a direct connection to the internet. To access the internet, you typically need a modem, which converts digital signals from your internet service provider (ISP) into a format that your devices can understand.
That being said, there are some exceptions. For example, if you have a fiber-optic internet connection, you might not need a traditional modem. Instead, you can use an optical network terminal (ONT) to connect your Ethernet devices directly to the fiber-optic network. However, this is a specialized setup that requires specific hardware and infrastructure. In most cases, a modem is still necessary for internet access via Ethernet.
What is the difference between a modem and an Ethernet switch?
A modem and an Ethernet switch are two distinct devices that serve different purposes in a network. A modem is a device that connects your local network to the internet by converting digital signals from your ISP into a format that your devices can understand. An Ethernet switch, on the other hand, is a device that connects multiple Ethernet devices within a local network, allowing them to communicate with each other.
While a modem is necessary for internet access, an Ethernet switch is optional but highly recommended for larger networks. An Ethernet switch can help improve network performance, reduce congestion, and provide more ports for connecting devices. However, it’s essential to note that an Ethernet switch does not provide internet access on its own and must be connected to a modem or another internet-enabled device to access the internet.
