Boolean searching

The Internet is a vast computer database. As such, its contents must be searched according to the rules of computer database searching. Much database searching is based on the principles of Boolean logic. Boolean logic refers to the logical relationship among search terms, and is named for the British-born Irish mathematician George Boole.

bandwidth

In computer networking and computer science, the words bandwidth, network bandwidth, data bandwidth,. or digital bandwidth are terms used to refer to various-bit rate measures, representing the available or consumed data communication resources expressed in bits per second

latency

Latency is a measure of time delay experienced in a system, the precise definition of which depends on the system and the time being measured. In communications, the lower limit of latency is determined by the medium being used for communications. In reliable two-way communication systems, latency limits the maximum rate that information can be transmitted, as there is often a limit on the amount of information that is "in-flight" at any one moment. In the field of human-machine interaction, perceptible latency has a strong effect on user satisfaction and usability.

advanced search

The advanced search allows you to combine several search terms in order to tailor the search results to suit your needs. You can choose to search all or any of the terms you specify and you can even choose terms to exclude from the search.
