The concept of Headboard It is used in various ways. Either in its feminine (header) or masculine (header) form, it may refer to the piece of furniture which is located in the sector of the bed where the pillows .
This header may have an aesthetic purpose or be used to protect the wall of the spots that are produced by rubbing. For example: “I would like to have a large double bed with 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 with the headboard”.
Rectangular tables also have headboards, which are the two smallest ends. If we pay attention to protocol issues, these two points should sit the most important people in the group, those who are in the highest positions of 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 assigned to managers and directors.
In the field of architecture , is called header to the part of a religious building which is opposite the imafronte (the facade). Usually the head is oriented to the east and usually houses the altar. The style of the header, however, varies according to the time.
The idea of header also appears in the field of telecommunications and of the computing . In a cable television system, the header is the installation that receives the signals to process them and then distribute them via cable.
The header or header , on the other hand, is the information complementary that is located at the beginning of a block of data and that indicates how the data in question should be treated.
There is also the term header file (with its variations, such as header file or of inclusion, all derived from the English concept header file), which refers to a file that the compiler should automatically include when processing another, as instructed by the developers. The programming languages in which this practice is used are C and C ++, among others.
Usually, a header file consists of a declaration direct from certain identifiers, such as variables, classes and subroutines. When a programmer needs to declare a standard identifier in several code files, he can put them in a single header file and then include it when necessary. The declaration of standard functions in the C and C ++ libraries are usually made 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 comfort, rather than using a single file of considerable length. At present, this practice is the most common, so it is not a tactic that only the most skilled use, but a fundamental aspect of the programming In certain languages.
Of course, like everything else, header files have their disadvantages. For example, they force the developer to make changes in two different places each 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 name schemes, although one of the negative consequences is an increase in the necessary space and execution time.
In the administrative or political organization of a territory, finally, it is called the head of a town that acts as capital of a region, housing government institutions. Header is also called main urban center of an area.
