This website is mainly discussing the importance of the”privacy issues and data storage”. For this topic, we have to discuss three related subjects. They are “PRIVACY”,”SECURITY”, and “STORAGE”. When we using internet, the first thing we have to notice is “PRIVACY”. Internets are widely used for services like browsing, shopping or banking, just to name a few. While surfing on the cyber world our personal ID number and visa card details can be easily exposed. The hackers/computer criminals might use virus to destroy your stored data, or use some hacking programme  (trogen horse) to steal valuable data from you. Therefore our second issue is to have some knowledge of “SECURITY”. We have to take some protection to prevent our personal info been stolen or destroyed. We might need to install some antivirus application programmes, such like “Norton”. Or “Nod”. However, the protection programme has its limitation. While the virus or hacking skill will grow and update faster then we can imagine, hence the ultimate operation is to introduces, the “backup”. Of the existing system when there is no important part of system maintenance.
