Computer ethics is a branch of practical philosophy which deals with how computing professionals should make decisions regarding professional and social conduct. The term "computer ethics" was first coined by Walter Maner[1] in the mid-1970s, but only since the 1990s has it started being integrated into professional development programs in academic settings. The conceptual foundations of computer ethics are investigated by information ethics, a branch of philosophical ethics established by Luciano Floridi. Computer ethics is a very important topic in computer applications.

You might think that modern PCs have more than enough memory. Even budget systems come with at least 2GB, and you can add 2GB more from as little as £20. 4GB of RAM should be enough for everyone, right?

Well, maybe not. Windows Vista needs 2GB to run properly, and large apps can swallow up a gigabyte more with ease. You can very quickly find that your 2GB system is grinding to a halt. Installing another 2GB may not make much difference. Very few 32-bit systems are able to access the full 4GB of memory – some can use less than 3GB. And upgrading to 64-bit Windows doesn't always help.

Fortunately, there is one way to deliver guaranteed results. Learn just a little about how Windows and your applications use memory and you can begin to fine-tune your PC, reducing RAM wastage, making more efficient use of system resources and hopefully delivering a real and lasting improvement to your system's performance.
