After thousands of computers filtered through massive amounts of data, the Einstein@Home project identified a 40.8-hertz pulsar.

Authorization lets network administrators restrict features to particular users as a security measure.

Key logging software lets someone spy on what you type. It´s one of many potential security threats against which computer users in general and cloud computing companies in particular must guard

Autonomic computing is a self-managing, self-repairing system that can predict, respond to and resolve problems automatically. It´s still a developing form of computing — no one has perfected it yet.

Middleware allows computers to communicate with a cloud computing network.

Distributed computing systems like SETI@Home and Folding@Home leverage your computer´s unused cycles to analyze petabytes of data. First, a centralized system divides the data into manageable chunks and sends it out to your computer. When your computer finishes analyzing the data, it sends findings back to a central computer.

An integrated development environment (IDE) is the environment and tools programmers use to develop and test applications before rolling them out to a cloud computing system.

SETI@Home is the oldest of the three public distributed computing projects.

In a heterogeneous computer network, all the computers are the same make and model. This makes it easier to maintain, repair and replace machines as they malfunction.

Distributed computing systems are grid computing networks distributed across the Internet, which is a network of networks.
