What does overloading mean?
Overloading means loading a person, machine, network, or other system beyond what it can comfortably or safely handle. The term is especially common in computing, where excessive traffic or demand on a server can lead to slow performance, errors, or failure. In programming, overloading has a more specialized meaning: several functions or operators may share one name while accepting different kinds of arguments, with the appropriate version selected from its context. The word can also describe an electrical component receiving more power than its rated capacity. As the present participle of overload, it appears in phrases such as “overloading the system” and “overloading the grid.” Its strong implication is excessive pressure, although the programming sense is usually a neutral feature of a language rather than a fault.
The act or condition of loading a system or resource beyond its normal or safe capacity.

Common in computing, engineering, and electrical contexts; in programming, it may neutrally refer to defining multiple operations under the same name.
The present participle of overload, meaning to load a system or resource beyond its normal or safe capacity.

This is a present-participle form; in formal prose, the finite forms overload and overloads are often clearer in sequence.
The plural is grammatical but uncommon; plural nouns or constructions are usually preferred in technical writing.
"The report documented repeated network overloadings during peak periods."
In programming, overloading lets one name perform different jobs, so the meaning depends on the context in which that name is used.

Where does overloading come from?
The word is formed from the prefix over- and the verb load, both of which have Germanic roots. The combination originally conveyed putting too much material or weight into or onto something. In modern technical usage, the same structure developed senses involving demands beyond a system’s capacity and multiple programming operations sharing a single name.
