INTRODUCTION
A computer is an electronic device that can receive a set of instructions, or program, and then carry out this program by performing calculations on numerical data or by manipulating other forms of information.
The modern world of high technology could not have come about1 except for the development of the computer. Different types and sizes of computers find uses throughout society in the storage and handling of data,from secret governmental files to banking transactions to private household accounts. Computers have opened up a new era in manufacturing through the techniques of automation, and they have enhanced modern communication systems. They are essential tools in almost every field of research and applied technology, from constructing models of the universe to producing tomorrow’s weather reports, and their use has in itself opened up new areas of conjecture. Database services and computer.networks make available a great variety of information sources. The same advanced techniques also make possible invasions of personal and business privacy.Computer crime has become one of the many risks that are part of the price of modern technology.

引言
計算機是一種電子設備，它能接收一套指令或一個程序，然后通過對數值數據進行運算或者對其他形式的信息進行處理來執行該程序。
如果沒有計算機的發展，現代的高科技世界是不可能產生的。在整個社會，不同型號和不同大小的計算機被用于存儲和處理各種數據，從政府保密文件、銀行交易到私人家庭賬目。計算機通過自動化技術開辟了制造業的新紀元，而且它們也增強了現代通信系統的性能。在幾乎每一個研究和應用技術領域，從構建宇宙模型到產生明天的氣象報告，計算機無不是必要的工具，并且它們的應用本身就開辟了人們推測的新領域。數據庫服務和計算機網絡使各種各樣的信息源可供使用。同樣的先進技術也使侵犯個人隱私和商業秘密成為可能。計算機犯罪已經成為作為現代技術代價組成部分的許多風險之一。
