    Abstract : Popular Abstract in Swedish Surfplattor och mobiltelefoner med prestanda i klass med den hos stationära datorer för bara några år sedan är resultatet av den kontinuerliga hårdsatsning som i över 50 års tid stadigt lyckats göra den minsta elektronikkomponenten, transistorn, mindre, snabbare och mer strömsnål. Under senare år har det dock blivit svårare att förbättra prestandan enbart genom att minska transistorns storlek. READ MORE
