1) The main Printed Circuit Board (PCB) of a computer - referred to as a Mother Board because other smaller PCB´s are sometimes attached to it - this are in turn referred to as daughter boards.

2) Any PCB that can accept daughter boards.

RAM is a type of computer storage whose contents can be accessed in any order. This is in contrast to sequential memory devices such as magnetic tapes, discs and drums, in which the mechanical movement of the storage medium forces the computer to access data in a fixed order. It is usually implied that RAM can be both written to and read from, in contrast to read-only memory or ROM.

Computers use RAM to hold the program code and data during execution. In the first electronic computers, RAM wa...

Abbreviation of Printer Control Language, the Page Description Language (PDL) developed by Hewlett Packard and used in many of their laser and ink-jet printers. PCL 5 and later versions support a scalable font technology called Intellifont.

An address referring to a document on the Internet. This can be used to reference a web page via HTTP or a file to be accessed via FTP, for example. The reason for a URL (rather then just the address) is to define completely what a computer must do, and where it must go, to access a document (sometimes even on it´s local hard drive in the case of ´file:´)

The syntax of a URL consists of four elements:

Protocol://address/path/document - here are a few examples:

The area of sharpness in a picture, extending in front of and behind the plane of the subject, that is most precisely focused by the lens.

You can control depth of field by varying three factors:
1) the size of the aperture
2) the distance of the camera from the subject
3) the focal length of the lens.

If you decrease the size of the Aperture, the depth of field increases; if you focus on a distant subject, depth of field will be greater than if you focus on a near subject; and if you...

A universal format for data on the Web. Using a simple relational model, it allows structured and semi-structured data to be mixed, exported and shared accross different applications. RDF data describe all sorts of things, and where XML schemas just describe documents, RDF and OWL schemas ("ontologies") talk about the actual things. This gives greater re-use. where XML provides interoperability within one application (e.g. bank statements) using a given schema, RDF provdies interoperab...
