👉 Executing computations, or "executions," refers to the process of running a program or executing code instructions on a computing system. This involves translating high-level programming languages into machine code that the CPU can execute directly. Execution involves several stages, including parsing the source code to understand its structure and semantics, compiling it into an intermediate or target machine code, and finally, executing this code by the CPU. Modern systems often use Just-In-Time (JIT) compilers or Virtual Machine (VM) engines to optimize and manage these executions, allowing for efficient and dynamic code execution. Execution units within a CPU, such as the Arithmetic Logic Unit (ALU) and registers, play crucial roles in processing these instructions, enabling complex computations and data manipulations that form the backbone of software applications.
