Answer 1

Portable Executables (PE) are files that contain all the necessary information for the operating system to correctly load executable code (.exe, .dll, ...)

This may include dynamic library references for linking, resource management, TLS data, among other things.

Executables (.exe), however, are the files that denote the main execution point on a computer program, that is, speaking in C# terms, the file that contains the Main function or entry point.
