The second type of activity is characterized by prevalence of the evident and figurative, informing and structuring functions of signs, and sign an are more flexible though are also set in certain sign and models, need to make operations of decoding of difficult messages (forms, patterns is prevailing.

Computer education to which a lot of attention is paid recently, has to include not only and not so much knowledge of the device of computers, how many ability to use them in a professional. Different categories of users require the differentiated training in informatics.
