In computer science, runtime or execution time is the time during which a program is running (executing), in contrast to other program lifecycle phases such as compile time, link time and load time. A run-time error is detected after or during the execution (running state) of a program, whereas a compile-time error is detected by the compiler before the program is ever executed. Type checking, register allocation, code generation, and code optimization are typically done at compile time, but may be done at run time depending on the particular language and compiler.<ref>Definition - What does Run Time mean?

 == What is a Run time (Program Lifecycle Phase)? ==
 '''Run time''', in the context of a program's lifecycle, refers to the phase when a program is actively executing on a computer. This is the period after a program has been launched and runs in the computer's memory, processing input, performing operations, and producing output until it terminates.
@@ Line 14: / Line 17: @@
 Run time is the time it takes to run the program after it has been compiled. The binary code is issued to be executed on a particular architecture, such as ARM or x86. Run time measurements are made by setting a time stamp before and after the method calls of adaptor methods, and then taking the difference between the two.

 Run time is used to:
 *Execute the program’s code on the system’s processor.
 *Allocate and manage memory for program operations.
@@ Line 16: / Line 41: @@
 *Interface with other software and hardware components.
 *Manage resources like file handles and network connections.
 The user’s input, system configuration, and interaction with other applications and operating systems influence the program's behavior during run time.
-Run time is crucial because it directly impacts software applications' performance, reliability, and efficiency. During run time, all the software functionalities are realized, and the program interacts directly with the system environment and the user. This phase determines how well a program meets its performance criteria and user expectations in real-world scenarios.
+== Importance of  Run time (Program Lifecycle Phase) ==
 The benefits of a well-managed run time include:
 *Efficient Resource Management: Optimal use of system resources like CPU and memory.
 *Error Handling: Capability to manage and recover from errors during execution.
@@ Line 33: / Line 56: @@
 *Security: Implements run-time checks and balances to protect against vulnerabilities.
 Examples of run time include:
 *A web browser running and rendering web pages based on user interactions.
 *A database system processing queries and transactions.

 *A mobile app responding to user inputs and fetching data from the internet.
 *Video games rendering graphics and processing real-time user inputs.
 Each example highlights how software behaves during its run time phase, interacting dynamically with inputs, other programs, and system resources to deliver intended functionalities.

 *Compilation: Explaining how source code is translated into executable code is crucial for understanding what occurs before runtime.
