A developer at an embedded systems company writes firmware in C for a microcontroller. The team must deploy the compiled binary to thousands of devices with no runtime environment available on the hardware. Which characteristic of the toolchain makes this deployment model possible?

The C compiler translates the entire source code into native machine code before the program runs

The linker embeds a virtual machine into the binary so the code runs on any architecture

The preprocessor converts C into portable bytecode that the hardware interprets directly

The C interpreter executes each source line at runtime, allowing the same code to run on any CPU

What is a key characteristic of interpreted languages?

They always produce a standalone executable file

They cannot be used for web development

They are always faster than compiled languages

Source code is executed directly without a prior compilation step

How do programs typically use libraries?

By executing the library as a separate process

By converting the library into machine code before each run

By linking or importing them to access pre-written functionality

By copying the library source code into every program

What is the fundamental concept of object-oriented programming?

Code is written in a single continuous block

Programs are structured as a sequence of procedures

Objects encapsulate data and methods that operate on that data

Functions are pure and data is immutable
