Answer:
Step-by-step explanation:
The main difference between a program and a script lies in their execution and purpose.
A program is a set of instructions that tells a computer what to do. It is typically compiled into an executable file before being run. Programs are usually written in programming languages such as C++, Java, or Python. They are used to create complex applications, perform calculations, manipulate data, and interact with hardware.
On the other hand, a script is a program that is interpreted and executed directly by another program, called an interpreter. Scripts are often written in scripting languages like JavaScript, Python, or Bash. They are used to automate tasks, manipulate files, perform simple calculations, and modify system configurations.
Here are a few key differences between programs and scripts:
1. Execution: Programs are compiled before they are executed. This means that the source code is converted into machine code that can be directly run by the computer's processor. Scripts, on the other hand, are interpreted line by line at runtime. The interpreter reads each line of the script and executes it immediately.
2. Complexity: Programs are generally more complex and larger in size compared to scripts. They are designed to handle complex tasks and are often part of a larger software system. Scripts, on the other hand, are typically smaller and focused on performing specific tasks or automating simple processes.
3. Portability: Programs are compiled into machine code, which makes them platform-specific. A program compiled for Windows, for example, may not run on a Mac or Linux machine without modification. Scripts, on the other hand, are generally more portable. As long as the interpreter is available on the target system, the script can be executed.
4. Development Process: Programs usually follow a structured development process, involving design, testing, and debugging. They are often developed by a team of software engineers. Scripts, on the other hand, are often written by individuals or small teams without strict development processes. They are more flexible and can be quickly modified or extended.
In summary, programs are compiled and run as standalone applications, while scripts are interpreted and executed by an interpreter. Programs are typically larger, more complex, and designed for specific purposes, while scripts are smaller, simpler, and used for automation or quick tasks.
