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.
While most metals are hard, lead and gallium are examples of elements that are soft. These elements tend to have lower melting and boiling points than the transition metals (with some exceptions).
