Writing is the representation of language in a textual medium through the use of a set of signs or symbols (known as a writing system). It is distinguished from illustration, such as cave drawing and painting, and the recording of language via a non-textual medium such as magnetic tape audio. In Eurasia writing began as a consequence of the burgeoning needs of accounting. Around the 4th millennium BC, the complexity of trade and administration outgrew the power of memory, and writing became a more dependable method of recording and presenting transactions in a permanent form (Robinson, 2003, p. 36). In Mesoamerica writing may have evolved through calendrics and a political necessity for recording historical events.Writing, more particularly, refers to two things: writing as a noun, the thing that is written; and writing as a verb, which designates the activity of writing. It refers to the inscription of characters on a medium, thereby forming words, and larger units of language, known as texts. It also refers to the creation of meaning and the information thereby generated. In that regard, linguistics (and related sciences) distinguishes between the written language and the spoken language. The significance of the medium by which meaning and information is conveyed is indicated by the distinction made in the arts and sciences. For example, while public speaking and poetry reading are both types of speech, the former is governed by the rules of rhetoric and the latter by poetics.
