Multinational Companies tend to have millions of users from all over the globe who use their services and in doing so provide their information. This information gets saved on the databases of these companies. It is then up to the company on how they will use this information. This is where ethicality comes into play. A company can act ethically and protect the information that has been entrusted to them by their user, or they can act unethically and use the users' personal data to make profits. It has recently come to light that some companies have been using users' private data and would sell it to other companies for profit. These buying companies would then use the data for a variety of things such as ad targeting and statistics. These companies profited massively and the actual owners of the data did not, which makes this incredibly unethical.
This delay in routers is what we called Packetization delay
or also called Accumulation delay. Packetization delay is the time required for
the information to pass on the wires. The data rate of the links that passes
thru the wires cause the delay.
