Lab 2 Summary Notes

All information is based around a relation. Relations that are among signs objects and anything else that are capable of understanding. A sign informs an agent about things. Everything’s based among a relation (information) about anything that can be decoded. To understand informatics you must first understand sign system and context. Context, meaning the circumstances that form the setting for an event, statement, or idea. Syntax meaning sentence structure, semantics are the actual meaning of the sentences, and pragmatics meaning language and the context in which it used. Icons represent objects. Things like computer icons, footprints in the sand, pictures of curvy roads, etc. then an index is what represents the object. Symbols of things, objects, etc are of choice or of ones personal whim. Combining two different elements or hybrids can also make sings. Since signs are made by choice, they can be manipulated and confusing to many. They can be of opinion, which could mean only certain people, understand. The lecture also discusses how effective and productive electronic channels are in their transmission. Cluade Shannon explored information with electrical channels and how they pass on or transmit elsewhere. His experiments and willful thoughts became known as the information theory.
