When you buy distribution software or any other type of software, you have two basic options. First of all, you can get the program sent to you on a disc, and you can then put the disc into your computer and install it from the files that are contained there. Your other option is to download all of those files, install the program, and have it instantly.
The clear upside to downloading the software is that you can get it in just a few minutes. If you had to have it mailed to you, it could take weeks. The download is fast and means that you can start using the program sooner. This is also beneficial for computers – like the new netbooks that are flooding the market – that do not even have disc drives.
There are a few downsides to this process, though. For one thing, it is going to be almost impossible if you are still using a slow Internet connection, such as a dial-up connection. There is also the issue of taking up more space on your hard drive since you have both the downloaded file package and the program on the computer. If your hard drive is full, this may not wok.
On the whole, downloading software is a much better option as long as your system is set up for it. If not, buying a disc is fine, but more and more people in the modern computer age are turning to downloading programs instead.
