Q:

Does a USB connection or an Ethernet connection transfer data faster?

A:

As of 2014, an Ethernet connection has a higher speed capacity than USB connections. Ethernet bandwidth can currently reach speeds of up to 100 gigabits per second, while the USB 3.1 format can only reach 10 gigabits per second.

Speeds of around 100 megabits to 1 gigabit per second are more commonly found in commercial Ethernet products. Home broadband Internet connections in the U.S. average only 10 megabits per second as of April 2014, making current devices adequate for a majority of users. USB connections, as well as most Internet connections, are considered asymmetrical, meaning the speeds at which data is uploaded and downloaded are different. Ethernet connectivity is often chosen over USB because of the ability of the cable to transfer more electrical power. Power over Ethernet devices include wireless access points, VoIP services and security cameras.

    What are the advantages and disadvantages of using Ethernet cables?

    A:

    Ethernet cables are conceptually simple to install, support quick transfer speeds  and are fairly affordable. Ethernet cables are difficult to troubleshoot and require a lot of effort to reconfigure once installed. Although Ethernet cables are well-shielded and offer better immunity to noise, they require the installation of specialized cables to fit different networks.

  • Q:

    How do you make an ethernet cable?

    A:

    To make an Ethernet cable, cut a length of cable, strip the jacket from both ends, spread apart the wire pairs, untwist them, trim the wires, insert each end into a modular connector, and secure the connectors with a crimping tool. When finished, test each end with a cable tester.
