Ethernet and USB are computer standards for data transmission. Ethernet connects devices to local area networks, while USB connects peripherals. Ethernet to USB adapters can be used to connect computers without Ethernet ports to LANs or high-speed modems. There are simple one-to-one adapters and more complicated hubs with multiple ports. Multiple Ethernet ports can be used to share internet access with a second device by bridging two network connections.
Ethernet and universal serial bus (USB) are both standards that computers can use to transmit data. The primary use of Ethernet is to connect computers and devices to local area networks (LANs). USB is typically used to connect a wide variety of peripherals to computers, which can include devices such as hubs or adapters. If a computer does not have an Ethernet card, you can use an Ethernet to USB adapter to connect it to a LAN. Another potential use for these adapters could be to connect to a high-speed modem that doesn’t have a built-in USB port.
Many computers are equipped with Ethernet ports to facilitate network connectivity. These ports are available on many motherboards, in which case no additional ethernet card is required. If a computer doesn’t have an Ethernet port, it can be difficult to connect it to a network or access the modern high-speed Internet. The two solutions usually involve installing an Ethernet card or using an Ethernet to USB adapter. Some applications, such as laptops, may not allow a card to be installed, while in others, an external adapter may be the easiest route.
There are two main varieties of Ethernet to USB adapters. The simplest form typically consists of a male USB socket and a female Ethernet socket, along with the necessary electronics to join the two. This type of connector can be useful if your computer has a number of unused USB ports and doesn’t have the ability to connect to a router or modem via Ethernet. Of the two types of Ethernet to USB adapter, the simple one-to-one variety is usually the least expensive.
In addition to simple adapters, more complicated Ethernet-to-USB hubs are typically available as well. These units may be powered through the USB connection or may require an external source of electricity. A hub drive will typically have a variety of different ports, including an Ethernet jack and one or more USB connections. This type of Ethernet to USB adapter can be useful if your computer has very few USB ports or if you need to connect multiple devices at the same time.
Some circumstances may require a second network port, which is another way an Ethernet to USB adapter can be used. One potential use of multiple Ethernet ports on a computer is to share Internet access with a second device, which is typically accomplished by bridging two network connections. This can be an Ethernet port and a Wi-Fi® connection or two Ethernet jacks. If one Ethernet port is connected to another and one is connected to a modem, the other can be connected to a second computer, also providing access to the Internet.
