Our knowledge of computer

Computer applications have received popularly many attention in the past decade among people. We all try to learn new aspects of using Internet, working with the system and experiencing in various softwares for photo, music and movie handling.

There are many advanced things that ordinary people can not perform and require a higher knowledge of computer science. The important thing in this artificial world, however, is to understand that we are lacking in some particular parts.

For example, did you know that all deleted files (after emptying the recycle bin) and even after formatting a drive (including flash memories) can be retrieved! There are many files on the web that you can download and do this. Another thing is that when you connect to the Internet there is an IP assigned to you that acts as your identity. It is very easy to find out where, when and how a person enters a website and for how long. Also, be very careful with the instant messengers! Do not click on any link that is sent to you, do not run or transfer any file unless you are pretty confident that it is safe. Choose strong passwords (include numbers and signs) and change them on a regular basis.

There are always sick people on the web who are waiting for a moment to gain access to your computer and personal information.
