'''Static''' can refer to more than one thing:
- Used in everyday speech as shorthand for static electricity, or as a slang term for hardheadedness (as in "Don't give me static").
- In consumer electronics, static is a synonym for white noise.
- In literature, static mean "not changing"; as in the term "static character", or, a character who does not significantly change over the course of the work.
- In mechanics, static implies a system that does not possess a deterministic processes or changing variable values, but is a well-defined system which only involves the current values. This type of system is the opposite of dynamic systems, and is studied in statics.
- In computer science/computer engineering, the word static has many unrelated definitions, which may be confusing for novices. Some of the more common uses of the word are:
# In
object-oriented programming, static refers to a property of an object which belongs to the object's class and not the object itself. This term is not used universally among object-oriented programmers, but is consistent with its use in popular object-oriented programming languages
C++ and
Java.
# In reference to
data, static means unchanging.
# In the context of
programming languages, static typing is a particular way the
syntax of the language associates
identifiers with data, in particular the
type of the data.
# In reference to
linking, static means that identifiers are associated with data or sections of code during linking, as opposed to dynamic linking in which these associations may be formed at
runtime.
# In
networking, static means fixed, especially fixed with respect to a particular piece of
hardware.
# In reference to
RAM, static refers to details of the underlying electronics and should not be confused with static data as the terms are unrelated. See static RAM.
# In
digital logic, static is used to distinguish most types of logic design from
dynamic logic. Both types of logic are used in the design of processors.
#
Static analysis is a set of methods for analyzing code without running it.
The term static should be used with care when the context is not clear.
