A+
array
A collection of items stored in a contiguous memory block, each
identified by an index number.
composite variable
A variable that can hold multiple pieces of data, often grouped
together under a single name.
container
A data structure that holds a collection of elements, providing
methods to add, remove, and access items within it.
,data structure
A way of organizing and storing data in a computer's memory
designed to facilitate the efficient retrieval, insertion, and deletion of
data.
linked list
A sequence of elements where each element points to the next
one, forming a chain.
linked structure
Any structure composed of elements connected by links or
pointers, enabling dynamic relationships among data elements.
list
A collection of items arranged in a linear sequence, allowing for
easy access to and the insertion and deletion of elements.
queue
A data structure that follows a first-in, first-out (FIFO) order where
elements are added to the back and removed from the front.
,record
A data structure that groups related pieces of information under a
single name, typically consisting of multiple fields or attributes.
stack
A data structure that follows a last-in, first-out (LIFO) order where
elements are added and removed from the same end, known as
the top.
argument
The actual value or data you pass to a function or subprogram
when you call it.
parameter
A variable in a function or subprogram definition that acts as a
placeholder for the value (argument) you pass when you call the
function.
parameter list
A set of parameters defined in a function or subprogram
specifying the number and types of inputs the function can
accept.
, reference parameter
A type of parameter that allows a function to modify the actual
variable passed to it.
subprogram (function)
A general term for a block of code that performs a specific task
and can be reused.
value parameter
A type of parameter that passes a copy of the argument's value to
the function.
asynchronous
a type of operation that runs independently of the main program
flow,
allowing additional tasks to happen without waiting for others to
complete
bytecode
a low-level, platform-independent code that is executed by a
virtual machine, typically produced by compiling source code
