The component that interprets each instruction issued by a program and initiates the corresponding action is known as the Central Processing Unit (CPU). The CPU processes instructions from software, executing tasks by performing calculations, moving data, and controlling other hardware components. It acts as the brain of the computer, coordinating all operations to ensure the program runs smoothly.
A command is an instruction given to a computer or a program to perform a specific task or action. Its purpose is to direct the system to execute operations, such as manipulating data, controlling hardware, or managing processes. Commands can be entered through various interfaces, including command-line interfaces or graphical user interfaces, allowing users to interact with software and hardware efficiently.

In QBasic, a command is a specific instruction that tells the computer to perform a particular action. Commands can include operations like inputting data, performing calculations, controlling program flow (such as loops and conditionals), and outputting results. Examples of common QBasic commands include PRINT, INPUT, IF...THEN, and FOR...NEXT. These commands form the building blocks of QBasic programs, allowing users to create various applications and scripts.
