In this project we have decided to tell what models of processors exist now, what technologies prevail, what models are in demand in Lithuania and abroad, what advantages you can get if you buy one or other processor type. Our first step was to interrogate as much as possible people to find out processors of the certain mark -how much itpopular, - we asked various age people few questions about type of their processor, when the had buy it and other. Also these questions allowed us to find out what processors in what time interval were used in the majority. The second step was gathering the information from official sources (official web-pages of the INTEL and AMD companies). The third step was generalization of the received information.
