Macro in Greek means “big” and refers to all kinds of science or technology that is related to or deals with studying large-scale phenomena.
The macro is that which attends to objects or entities on a larger scale than the conventional one, studying aspects that often cannot or are not analyzed in traditional investigations. The macro occurs both in science and technology and even in social orders.
In computing, for example, a macro or macroinstruction consists of a considerable set of instructions that are stored for later execution in the form of a sequence.
It is common to find macro functions in software such as the Office suite. For example, a macro in Access allows large-scale operations on records belonging to the same name, across multiple tables, or across files. In web development and programming, for example, macros help reduce the size of the source code, using abbreviations and simplified commands.
The macro functions in computing have the sense of avoiding the repetition of orders or identical parts in a program, allowing to speed up the operational task. Thus, the user or programmer can establish a macro with a specific name that, each time it is used, executes a series of instructions.
To operate with macros, a macro processor is often used, which is responsible for registering all macro instructions quickly.
But the macro is also used in other areas. For example, one can talk about macro photography when the photographer is dedicated to taking pictures of those things, objects or entities that are equal to or smaller than the size of the film or electronic sensor. Therefore, macro objectives or lenses are used that allow sharp focus at a small distance and magnification of what is captured. This type of technology is ideal for photographing small objects such as insects or phenomena that occur on a microscopic scale.
Finally, also in the social aspect one can speak of, for example, the discipline macroeconomicwhich deals with studying economic phenomena at a social and global level.
