Computer networks vocabulary words

In English, the plural form of words ending in -us, especially those derived from Latin, often replaces -us with -i.
There are many exceptions, some because the word does not derive from Latin, and others due to custom.
Conversely, some non-Latin words ending in -us and Latin words that did not have their Latin plurals with -i form their English plurals with -i, e.g., octopi is sometimes used as a plural for octopus.
Prescriptivists consider these forms incorrect, but descriptivists may simply describe them as a natural evolution of language.
