Data Structures - Linked List
A linear data structure where elements, called nodes, are connected
using pointers instead of being stored in contiguous memory.
In languages like C, C++, or Java, linked lists are usually
homogeneous because each node is defined with a fixed data
type.
In languages like Python or JavaScript, linked lists can store mixed
data types in different nodes, making them heterogeneous.
Linked Structure
Any structure composed of elements connected by links or
pointers, enabling dynamic relationships among data elements.
,Data Structures - Lists
A collection of items arranged in a linear sequence, allowing for
easy access to and the insertion and deletion of elements.
A list can hold multiple elements, and depending on the language,
the elements may be of the same type or different types.
Data Structures - 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.
Data Structures - Record
A record is a collection of related data items, usually of different
types, grouped together as a single unit.
A record can hold multiple fields or attributes, such as strings,
numbers, and booleans, each with its own data type.
,Data Structures - Stack
A stack is a linear data structure that follows the Last In, First Out
(LIFO) principle, meaning the last item added is the first to be
removed.
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
case sensitive
when a programming language treats uppercase and lowercase
letters as different characters
, Object Oriented Programming - Class
A blueprint for creating objects in object-oriented programming
that defines the properties and behaviors the objects will have.
Compiler
A tool that translates source code written in a high-level
programming language into machine code or bytecode that a
computer can execute.
