USB Connection Verses Ethernet Card

When you get broadband, you may be given the choice of connecting either via an USB port or an Ethernet Card.

USB all newer computers have them just like serial and parallel ports, and for all practical purposes they are much better than the 'old' type ports. Nevertheless, as you will see, there is a downside to them.
Ethernet (RJ45 telephone-type socket) most new computers have them built in but if not, you can get a NIC that plugs into a PCI slot.

As USB is very common your Broadband supplier may suggest that you connect using your USB port. However, if you do so, your aspiration of having a high-speed connection may not be met! As using USB you will require about 80% of your system resources to be able to achieve optimum browsing and download speeds. (It may be quicker than your old dial-up modem, but not as quick as the adverts tell you!).

System resource availability is dependent upon a number of tasks the computer is being asked to perform at any one time. Certain non-essential programs load as soon as the PC starts and will consume your precious resources.

This lack of resources very rarely affects an Ethernet connection.

Thus, using USB you can expect a greater fluctuation in speed verses the same machine connected via Ethernet.
