television broadcasting and video in the United States
(also currently in use in Japan). (2) The standard set by
the NTSC.
- native language
- (1) The instructions that a particular processor can
execute directly; machine language. (2) The text that an
executing program uses to communicate with a user or
environment; that is, the natural language of the end
user.

that best represents an object. Native RMF transfers data
more efficiently than other RMFs do.
- nested class
- A class defined within the scope of another class.
- new
- (1) A C++ keyword identifying a free storage allocation
operator. (2) A C++ operator used to create class

This control character is represented by \n
- node
- (1) In network topology, the point at the end of a
branch. T. (2) In a tree structure, a point
at which subordinate items of data originate. ANSI.
See root, tree, child
node, parent node.
(3) In database management, data that can be accessed by
more than one route.
- nonmember function
- A function that occurs outside a class. See member function.
- nonprinting
character
- See control character.
- nonsignaled
- In the Windows operating system, the state that an object
is in when it is suspended. For example, when a thread is
created and running, its associated thread kernel object

Committee.
- NTSC format
- A specification for color television, defined by the
NTSC, which meets or exceeds the following criteria: (a)
525 scan lines, (b) broadcast bandwidth of 4 megaHertz,
(c) line frequency of 15.75 kiloHertz, (d) frame
frequency of 30 frames per second, and (e) color
subcarrier frequency of 3.58 megaHertz. See National Television Standard Committee.
- NULL
- In the C and C++ languages, a pointer that does not point
to a data object. IBM. The pointer can be
converted to any pointer type.
- null character (\0)
- The ASCII or EBCDIC character with the hex value 00 (all
bits turned off). It is used to represent the absence of
a printed or displayed character. This character is named
<NUL> in the portable character set.
- null pointer
- The value that is obtained by converting the number 0
into a pointer, for example, (void *) 0. The C
and C++ languages guarantee that this value will not
match that of any legitimate pointer, so it is used by
many functions that return pointers to indicate an error.

- null statement
- (1) In the C language, a statement that consists solely
of a semicolon. (2) In the C++ language, an expression
statement with the expression missing.
- null string

(2) A character array whose first element is a null
character. I.
- null value
- A parameter position for which no value is specified. IBM.
- number sign
- The character #, also known as pound sign and hash
