What is the Booleo field?

Booleo field in computer programming is a sequence of values ​​that can only maintain true or false values. By definition, boolean can only be true or false and unable to hold any other mediation value. The field is a sequence of data types that occupy numerical positions in linear memory space. While the actual implementation of the Booleo field is often left to the libraries of a compiler or computer language, it is most effectively performed by bits instead of complete bytes or words. There are several uses for the Boolean field, including monitoring symptoms of properties and alignment settings for the physical hardware interface.

The idea of ​​a Booleo field comes from the original methods that were used to store computer information where there was a very small memory. The first implementation of the Booleo field was a bit of a field. This has used larger data types such as bytes or long integers to keep the information settingsdata on TRUE or FALSE. In this way, one byte, which is eight bits long, can hold eight different true or false values, save space and allow efficient operation of Bitwis.

As the size of the computer has increased, the need to use the bit fields has decreased. While using BITS offers the possibility to move bit and use logical operators that allow incredibly fast processing, it also requires its own code for processing these types of operations. Using a standard field structure to hold the bytes sequence is a simpler solution, but it requires much more memory during the program. This can be seen when creating a series of 32 Boolean values. With a little field, only four memory bytes will occupy the data, but the Boolean field can occupy anywhere from 32 to 128 bytes, depending on the system's implementation.

Some languages ​​for computer programming actually implement a little bitThe field when the type of boole field is used, even if it is not common. The Boolean field has the advantage that it is very easy to read when viewing the source code. Comparison and tasks are presented clearly, while with a little field, logical operators must be used "and", "or" and "no", which potentially creates a confusing code.

Despite easy use is one function that cannot be used with the Boolean field, Bitmask. Bitmask is the only byte or a larger data type that contains a sequence of real and false values ​​related to multiple conditions. In one operation, more bits can be checked in terms of their real or false states at once. With a number of Boolean values ​​based on the full issue, the same loop operation would have to be performed.
