Factors affecting network performance Not all networks are the same. As data is broken into component parts (often known frames, packets, or segments) for transmission, several factors can affect their delivery.
It is sometimes strange to see what elements combine to make a compound. Sodium, a soft metal which fizzes violently when put into water, and chlorine, a poisonous gas, make sodium chloride (NaCl), otherwise known as common salt! The elements are usually arranged in the Periodic Table.
Non-metals are the elements in groups 14-16 of the periodic table. Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets.
