  • Key concepts include algorithms, programming languages, data structures, and computer hardware.
  • Computer science is a constantly evolving field with new developments and discoveries.


At the core of computer science, **algorithms** are step-by-step instructions or rules for solving a particular problem. They are the foundation for all computational processes and drive the development of software applications. *Algorithms can be as simple as a set of instructions to solve a math problem, or as complex as the algorithms used by search engines to provide relevant search results.* Some common algorithm types include sorting, searching, and graph algorithms.

Programming Languages

**Programming languages** are used to write instructions that a computer can understand and execute. They provide a way for programmers to communicate with computers and develop software applications. *Each programming language has its own syntax and set of rules that govern the structure and behavior of the code.* Common programming languages include Java, Python, C++, and JavaScript.

Data Structures

**Data structures** are organized and structured ways to store and manipulate data in computer programs. They allow efficient access, insertion, deletion, and modification of data. *For example, an array is a simple data structure that can store a fixed number of elements of the same type.* Some other common data structures are linked lists, stacks, queues, trees, and graphs.

Computer Hardware

**Computer hardware** refers to the physical components of a computer system, including the central processing unit (CPU), memory, storage, and input/output devices. *The CPU is the “brain” of the computer that performs calculations and executes instructions.* Understanding computer hardware is important for developing efficient software that utilizes the capabilities of the underlying hardware.
