Användandet av trådlösa nätverk ökar med rask takt och blir allt vanligare. Enligt en artikel i Computer Sweden kommer de trådlösa näten att ha 20 miljoner användare om 4 år. Analysföretaget Gartner Group har nyligen gjort en undersökning bland företag, vars syfte var att ta reda på hur stort intresset var för WLAN. Resultatet visade att 50% av företagen funderar på att köpa och installera WLAN-lösningar (Planet Wireless september 2001). Syftet med detta arbete var att beskriva hur den inbyggda krypteringsfunktionen WEP som för Wired Equivalent Privacy fungerar och hur säker den är, dvs hur lätt man kan knäcka krypteringen. Följande frågeställningar har besvarats genom litteraturstudier och ett praktiskt försök: Hur är trådlösa nät uppbyggda? Hur fungerar den inbyggda krypteringen WEP och hur säker är den? Vad kan man göra förutom att använda sig av WEP för att skydda sig mot avlyssning/intrång? Det praktiska försöket bestod av att knäcka WEP-krypterade filer med hjälp av programmet WEPCrack.

Sammanfattning EDI är ett välkänt och beprövat sätt för företag att automatisera sina affärsprocesser. Det är också välkänt att EDI är dyrt att både inverstera i och att använda.

The purpose of this study is to investigate in what extension students experience that computer and videogames affect them. I have chosen to focus on the physical, mental and social affect that this activity might bring them. I have also examined how much time the students spends in front of the computer or the videogame and in which social context they play.The method I have chosen to use is a quantitative opinion poll which I used in three classes of the later junior high and I have also conducted five qualitative interviews.The conclusions I have drawn from this investigation are that computer and videogames affects teenagers both physically and mentally. Physically the affects of playing videogames mostly can be derived to the physical inactivity they expose themselves to. The students themselves did not experienced any positive physical affects from their playing.Amongst the mental affects that stood out the most I recognized the social training that online gaming provided and also the intellectual stimulation that certain games offered the player.

This document is a summary of my work to create a project management system for a small firm working with computer graphics. The intention is to manage customers, projects, images and invoices in the easiest possible way. To make the system as flexible as possible a web-interface was chosen which makes it possible to access the system from any computer, making it independent of any particular operating system. The only requirement on the user environment is that the computer must have a connection to the Internet to be able to access the system. The different techniques that have been used to develop the project management system is primarily Ruby on Rails and a MySQL database.
