Pop and IMAP are the two different approaches to build a distributed electronic mail infrastructure. Pop is the oldest method and best known. But, IMAP provides good support for the three modes of remote mailbox access such as offline, online and disconnected.
The time that webpages takes to load increases because, these resources take time to download over network. We can allow these resources to be saved or cached by a browser through http caching. Once a resource is cached, a browser will take the cached copy instead of downloading it again subsequently.Thus we can reduce the total payload size of the responses, reduce the bandwidth and can eliminate numerous HTTP requests for the required resources.
Cloud computing is the technology which uses internet and the central remote servers to maintain data and applications. In cloud computing, users are allowed to access their personal files at any computer which has internet access, without installing any applications. The centralized data storage, processing and bandwidth makes this technology more efficient.
suPHP provides an additional layer of protection on servers. It causes php scripts to run under the account username instead of the user nobody?which is the user that apache/php would run under on a server that is not running suPHP. This feature allows us to more easily track any potential security breaches that come in via insecure php script(s) that a user is running.
