A bot is a script: an executable file that sits on your computer or on a server. Code is used to describe *how* the bot makes a connection, *what* functions it has and *when* it comes into action.
There are a whole range of programming languages that a bot maker can use to make a bot. The choice for a specific language is often based on the preference of the programmer. However, the choice for a programming language can also be based on the availability of a so called *library*: a friendly wrapper that enables a programmer to interact with an API.
The term API is an acronym for Application Programming Interface. It is an code-based interface either between multiple applications or between the programmer and a platform, such as Wikipedia, Reddit, Whatsapp, Twitter or Mastodon. Not all communication infrastructures have an API, it is a decision of the owner of the infrastructure to make one. Having access to an infrastructure through a programming interface is not a default. Also, every API is different and each one comes with its own rules and constraints.
> Among other things, web APIs encompass: a physicality in terms of the corporeal landscape of infrastructure and technology, through to the economic logics at work (i.e. business models, ownership, licencing of the APIs), functions and services (i.e. access to data), practices of users (i.e. forms of labor, play and collaboration), discursive formations (i.e. statements, knowledge, ideas), rules and norms (i.e. design principles, terms of service, technical standards), as well as social imaginaries and desires.
When looking at APIs from a technical perspective, we see a set of rules that applications use to communicate with each other. This apparently neutral conception is in reality a very complex conglomerate of imaginaries, whether technological, economical or societal.
Essentially the API determines how the platform developers imagine it will be used by other developers, revealing a relationship of imbalanced power. It welcomes interventions as an opportunity to expand the functionalities beyond what the original developers might have imagined. On centralized infrastructures this often results into generating more economical value in the end.
A computational *process* is nothing more then a running script. In the simplest version, this can be done from your own computer. In a more complex version, you could upload your script to a server and run it from there continuously as a **background process**.
As bots usually operate over a long period of time, you might not want to run them from your own computer, as this means that you need to keep your computer on all this time (imagine you want to keep a bot running for a year!).
Instead, bot makers often run their bots from a server as a *background process*, which allows them to be continuously active without any further intervention from the programmer.
