Communication (from Latin commūnicāre, meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules. The basic steps of communication are the forming of communicative intent, message composition, message encoding, transmission of signal using a specific channel or medium, reception of signal, message decoding and finally interpretation of the message by the recipient. The study of communication can be divided into: information theory which studies the quantification, storage, and communication of information in general; communication studies which concerns human communication; biosemiotics which examines the communication of organisms in general. The channel of communication can be visual, auditory, electromagnetic, or biochemical. Human communication is unique for its extensive use of abstract language.
A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media.
Copywriting is written content conveyed through online media and print materials. Copy is a content primarily used for the purpose of advertising or marketing. This type of written material is often used to persuade a person or group as well as raise brand awareness. The ultimate goal of copy is to get the reader to take a particular action. The goal for a copywriter is to create remarkable content that the reader finds valuable and makes them want to take the recommended action. Copywriters (known as continuity writers in broadcasting) are used to help create direct mail pieces, taglines, jingle lyrics, web page content (although if the purpose is not ultimately promotional, its author might prefer to be called a content writer), online ads, e-mail and other Internet content, television or radio commercial scripts, press releases, white papers, catalogs, billboards, brochures, postcards, sales letters, and other marketing communications media pages. In book publishing, flap copy and jacket flap copy are terms for the brief summary of a book which often appears on the inside of the book's hardcover dust jacket; back cover copy is similar, often briefer text placed on the book's outside back cover; catalog copy is another book summary maintained in a publisher's catalog of published books. Copy can also appear in social media content including blog posts, tweets, and social-networking site posts.
