    Blob is a collection of binary data stored as a single object. You can convert this data type to String or from String using the toString and valueOf methods, respectively. Blobs can be accepted as Web service arguments, stored in a document (the body of a document is a Blob), or sent as attachments.

    Blob is part of System namespace which provide methods and classes for apex core functionality, so we have separate blob class, which include some functions that help us to deal with multimedia in salesforce, i.e PDF .

    A Binary Large OBject (BLOB) is a collection of binary data stored as a single entity in a database management system. Blobs are typically images, audio or other multimedia objects, though sometimes binary executable code is stored as a blob.
