The brain of the computer that performs instructions from programs and processes data. - Processor or Central Processing Unit (CPU), The component of a computer where data is saved and held for future use. - Storage (secondary memory), A system within a computer where data is temporarily stored for quick access by the CPU - Memory (primary memory), Storage that retains data even when the computer is turned off - Persistent (Non-Volatile) Storage, hard drives, USB drives - Storage devices, Temporary memory that stores data and machine code currently being used; erased when the computer is turned off. - Random Access Memory (RAM), Permanent memory used to store essential programs and data that do not change. - Read-Only Memory (ROM), Programs and operating systems that run on a computer and perform tasks. - Software, The physical components of a computer system, such as the CPU, memory, and storage devices. - Hardware, A set of instructions that a computer follows to perform a specific task or solve a problem. Programs can be applications (like word processors) or system software (like operating systems). - Computer program, A step-by-step procedure or formula for solving a problem or completing a task. Algorithms are fundamental to programming and computer science, as they dictate how data is processed. - Algorithm, A visual representation of a process or algorithm, using symbols and arrows to show the flow of steps and decisions. Flowcharts help in understanding and designing algorithms. - Flowchart, Software that manages computer hardware and software resources and provides services for computer programs. Examples include Windows, macOS, and Linux. - OS - Operating system, The set of rules that defines the combinations of symbols and keywords that are considered to be correctly structured statements in a programming language. Proper syntax is essential for code to run correctly. - Syntax, Symbols used in programming that perform logical operations on one or more boolean values (true or false). Common logic operators include AND, OR, and NOT, which are used to combine or modify conditions. - Logic operators,
