The PRE is an alternating pattern of ones and zeros that tells receiving stations that a frame is coming, and that provides a means to synchronize the frame-reception portions of receiving physical layers with the incoming bit stream. Start-of-frame delimiter SFD – 1 byte. The SOF is an alternating pattern of ones and zeros, ending with two consecutive 1-bits indicating that the next bit is the left-most bit in the left-most byte of the destination address. Destination address DA – 6 bytes. The DA field identifies which station s should receive the frame.. Source addresses SA – 6 bytes. The SA field identifies the sending station. This field indicates either the number of MAC-client data bytes that are contained in the data field of the frame, or the frame type ID if the frame is assembled using an optional format.

There are many sizes of switches available in the market with a varying number of ports ranging from 5 to 10, 12, 24 and anywhere up to even 64 ports.
Before you can start looking for an Ethernet switch that works for you, you should have a little background about how Ethernet switches can have an impact on speeds.
