Internet has made everything easy and the digital world makes it nearly perfect. Now we can transfer download file easily from the internet. You will never need any post mail to send letters, pictures, software CD, and many other things that have digital version.

However, many people do not realize the real function of internet. They only use it for social network, lifestyle, reading news, or other activities which do not involve file transfers. They still buy CD games in the buy mac games shop, while actually it is easier and less effort to download computer games at the website.

Using fully internet function also supports green action, for example, you can download production music instead of buying CDs in the music shop; it can reduce plastic usage. But remember, you will need extra storage if you like to download files from internet. 1 terabytes sometimes is not enough to keep those downloaded files.
