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.
What are Elements and Alloys? Metals can be elements or alloys. Elements are the basic building blocks of chemistry. Examples of elements: Oxygen, nitrogen, hydrogen, iron (Fe), copper (Cu) and niobium (Nb). Lead (Pb) is an element that was traditionally popular as an ingredient in casting alloys (and some other alloys) because it makes some metals softer, less brittle and/or helps them melt at lower temperatures.
