The pixel (a word invented from "picture element") is the basic unit of programmable color on a computer display or in a computer image. Think of it as a logical - rather than a physical - unit. The physical size of a pixel depends on how you've set the resolution for the display screen. If you've set the display to its maximum resolution, the physical size of a pixel will equal the physical size of the dot pitch (let's just call it the dot size) of the display. If, however, you've set the resolution to something less than the maximum resolution, a pixel will be larger than the physical size of the screen's dot (that is, a pixel will use more than one dot). url

Macromedia Fireworks (also known as FW for short) is a bitmap and vector graphics editor, developed by Macromedia and aimed at web designers (with features such as: slices, the ability to add hotspots etc.). It is designed to integrate easily with other Macromedia products, such as Dreamweaver and Flash, and is part of the Macromedia Studio 8 suite.

In object-oriented programming, slicing is an operation to slice off a target value by size of the base type, thus extra parts will be gone. This is not the same as array slicing, however it does have similar characteristics.

Circuit switching (Line Switching) is a method of transmitting information (voice, video or other streamed data) between endpoints within telecommunications systems. Each individual subscriber is allocated a dedicated channel of constant bandwidth, which must be maintained open for the duration of their call, even if no actual conversation is taking place and no data being transferred.

Circuit switched systems were used in the old fixed landline telephone networks, for point-to-point connections routed directly between terminals. However, circuit switching may still be the best option when uninterrupted large file transfers need to be sent, or for long voice calls and videoconferencing, but it seems to be mainly suitable for voice traffic. Circuit switching can be considered as the opposite approach to packet switching, which does not require a dedicated channel, and makes more efficient use of the network's resources.

A tag is a keyword which acts like a subject or category. A keyword is used to organize webpages and objects on the Internet. Each user "tags" a webpage or image using his/her own unique tag. An image or webpage may have multiple tags that identify it. Webpages and images with identical tags are then linked together and users may use the tag to search for similar webpages and images.

In computing, Cascading Style Sheets (CSS) is a stylesheet language used to describe the presentation of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can be applied to any kind of XML document, including SVG and XUL. The CSS specifications are maintained by the World Wide Web Consortium (W3C).
