Bezpieczne pobieranie informacji oraz plików ze źródeł internetowych

Never has the mankind been able to use such large resources so freely.

Answer the questions:

• What datadatadata can be downloaded from the Internet?

• Where can their reliable sourcesreliable sourcesreliable sources be found the easiest?

• How to download files from the Internet not violating the copyrightcopyrightcopyright?

DownloadingdownloadingDownloading is the process of receiving data from a remote system, such as:

• a server,

• a web server,

• an FTP server as well as peer‑to‑peer (P2P) and peer‑to‑mail (P2M) networks.

Downloading transfers entire files for local storage and later use.

One of the two most frequent causes of computer virus infection is downloadingdownloadingdownloading or installing the downloaded files on the computer. Even if you thoroughly examine what you download and from which web sites, other computer users may not do that. Children and users with no basic computer knowledge are usually the least alert. You can come across infected data when you search for a solution to a problem, gather information, but also quite accidently, when you download interesting data found on the Internet. Malicious software is most often hidden in programmes which are advertised as free (free download, free software). Never download such a software. If a computer programme is really free, you will surely find it on its provider’s web pages or on a trusted portal offering files. Messages informing about the need to install the latest updates of software and or about a new dangerous computer virus (false alerts) often encourage the user to open an infected file.

Take extra caution when you download files:

• an up‑to‑date antivirus softwareantivirus softwareantivirus software should be installed on your computer,

• the operating system and software on your computer should be updated,

• download only the datadatadata you need,

• download applications and device drivers from official downloadingdownloadingdownloading channels, i.e. from software providers’ web sites,

• avoid searching for files using search engines,

• decide if the web site you want to download data from is reliable.

The excellent source of computer programmes are the online shops of software providers, which also offer free software.
