A hub provides a central location where all the cables on a network come together. This card controls the flow of information between the network and the computer. Anyone on the network can access files stored on any other computer. This type of network is simple and inexpensive, but only can be used with fewer than ten computers. Everyone connected to the network can access the files stored on the central computer.
Ethernet is the most popular and least expensive way information can travel through a network.
Ethernet is the easiest type of network to set up. Ethernet works the same way people talk during a polite conversation. Each computer waits for a pause before sending information through a network. Ethernet can send information through a network at a speed of 10 megabits per second.
