Answer 1

Protohistory is the time period for which we have written records but they are few and still cannot be read. ... Prehistory is the period that begins with the appearance of human beings about million years ago and ends with the invention of writing.

Answer 2

Answer:

The history of writing traces the development of expressing language by letters or other marks[1] and also the studies and descriptions of these developments.

In the history of how writing systems have evolved in different human civilizations, more complete writing systems were preceded by proto-writing, systems of ideograph or early mnemonic symbols (symbols or letters that make remembering them easier). True writing, in which the content of a linguistic utterance is encoded so that another reader can reconstruct, with a fair degree of accuracy, the exact utterance written down, is a later development. It is distinguished from proto-writing, which typically avoids encoding grammatical words and affixes, making it more difficult or impossible to reconstruct the exact meaning intended by the writer unless a great deal of context is already known in advance. One of the earliest forms of written expression is cuneiform.[2]
