What is the symbol table?

Symbol table uses computer systems as a way of centralizing information and reducing programs. These tables act as a key to the secret code; The symbol or string is placed next to another, generally much more information. When the program reads the symbol that is connected to the symbol table, the program refers to the table and takes information rather than the symbol. This allows large information or commonly repeated structures to have only one record, which reduces the total size of the program.

The concept behind the table of symbols is very simple. One table contains a wide range of information used by the program, each with its own input and a unique associated symbol. This information could be code strings, information tuning, memory location, literally anything that the program could use for operation. Rather than to include this information in the program, the code simply refers to the table using its unique symbol.

There are two places where the symbol table is common: when compiling code to programs and connecting libraries used multiple programs. When used in programs, the actual table is usually absorbed into the program or is made to a shared library at the time of compilation. It is unusual to have the list separated because the change of list could have extreme consequences for the program. Although the table is transformed in this process, it is still the same basic thing, it is just included with another code.

When a table of symbols is interconnected in the library, how drastically it can work. The library of the connection is a set of information that is expected to be available at any time. These libraries are often shared by the operating system or family of related programs that are created by the same company.

Each of these libraries is FIS information about certain subjects. One library may contain a wide range of programming for drawing a window borderThe operating system's user interface, while the second may contain information about where a specific group of programs stores information in memory. Because the linking library can contain such a random range of information, they often include symbol tables.

Incorporating the symbol tables into Linker can be shared in the program series. This allows multiple programs to access the same data at any time. If all large number of programs require the same information, including the symbol table in the library, significantly reduces the size of the overall program group.
