The headboard of a bed plays an aesthetic role and protects the wall.
Cabecera is a concept that is used in various ways. Whether in its feminine form (headboard) or masculine (headboard), it can refer to the piece of furniture that is located in the area of the bed where the pillows are placed.
This headboard can have an aesthetic purpose or be used to protect the wall from stains caused by rubbing. For example: “I would like to have a large double bed with a headboard,” “I bought a wooden headboard to hide the dirty paint on the wall,” “When I tried to turn on the light, I hit my hand on the headboard.”
Head of a table
Rectangular tables also have headers, which are the two smallest ends. If we pay attention to protocol issues, the most important people in the group should sit at these two points, those who are in the highest positions in the hierarchy .
Within a traditional family, for example, it is the mother and father who must occupy these seats, while in a company they are allocated to managers and directors.
In a meeting, the people with the highest authority sit at the head of the table.
Different uses of the term
In the field of architecture , the part of a religious building that is opposite the imafront (the façade) is called the head. Generally the head faces east and usually houses the altar. The style of the header, however, varies according to the era.
In the administrative or political organization of a territory, a town that acts as the capital of a region, housing government institutions, is called the head. The main urban center of an area is also called the capital.
The leading idea also appears in the field of telecommunications and computing . In a cable television system, the headend is the facility that receives the signals to process them and then distribute them via cable.
Header or header
The header , on the other hand, is the complementary information that is placed at the beginning of a data block and that indicates how the data in question should be treated.
There is also the term header file (with its variations, such as header or inclusion file, all derived from the English concept header file ), which refers to a file that the compiler must automatically include when processing another, according to the instructions of the compiler. developers. The programming languages in which this practice is used are C and C++ , among others.
Typically, a header file consists of a direct declaration of certain identifiers, such as variables, classes, and subroutines. When a programmer needs to declare a standard identifier in multiple code files, they can put them in a single header file and then include it when necessary. The declaration of standard functions in C and C++ libraries is usually done in header files.
One of the advantages of using header files is that it contributes to the division of programs into small parts that can be organized and reused with great convenience, instead of using a single file of considerable extension. Currently, this practice is the most common, so it is not a tactic that only the most skilled use, but rather a fundamental aspect of programming in certain languages.
Of course, like everything, header files have their disadvantages. For example, they force the developer to make changes in two different places every time they want to modify a definition (something that happens when they add or remove parameters , among other cases). Certain languages, such as Java , replace header files with naming schemes , although one of the negative consequences is an increase in space requirements and execution time.
