A home router usually has four LAN ports, meaning that, straight out of the box, it can host a network of up to four wired networking devices. If you want to have a larger network, you will need to resort to a switch (or a hub), which adds more LAN ports to the router. Generally a home router can connect up to about 250 networking devices, and the majority of homes and even small businesses don't need more than that.

There are currently two main speed standards for LAN ports: Ethernet (also called Fast Ethernet,) which caps at 100 megabits per second (or about 13 megabytes per second), and Gigabit Ethernet, which caps at 1 gigabit per second (or about 150 MBps). In other words, it takes about a minute to transfer a CD's worth of data (around 700 MB or about 250 digital songs) over an Ethernet connection. With Gigabit Ethernet, the same job takes about five seconds. In real life, the average speed of an Ethernet connection is about 8 MBps, and of a Gigabit Ethernet connection is somewhere between 45 and 100 MBps. The actual speed of a network connection depends on many factors, such as the end devices being used, the quality of the cable and the amount of traffic.
