What is the start-of-image marker sequence commonly associated with JPEG files?

Explanation:
Recognizing file signatures and how a JPEG file begins is what this is about. A JPEG starts with a Start of Image marker, which is the two-byte sequence 0xFF 0xD8. Often the next marker is the APP0 segment, 0xFF 0xE0, which is commonly followed by the “JFIF” header. So the sequence FF D8 FF E0 identifies the start of a JPEG file. The other options are signatures for different file formats: MZ marks Windows executable files, 89 50 4E 47 is the PNG signature, and 25 50 44 46 is the PDF signature.
