Bandwidth
Bandwidth is the amount of information your
connection to the Internet can carry. On average, typical telephone
lines can carry 1K of information per second.
Banner
A banner is a graphic image (static, animated, or
rich media) that is placed on web sites as an advertisement. Banners
are commonly used for brand awareness and generating sales.
Behavior
Microsoft implemented the behavior attribute of Cascading
Stylesheets in a way that enabled object-oriented programming to
enter the world of Web authoring. By encapsulating dHTML in an
external object, the properties and methods of that object can be
used. A Web page can then use these objects with the behavior
attribute. This means, for example, that a Web author no longer has
to perform an explicit browser detection.
Bit Depth
Bit depth describes the file size of an image by orders of
magnitude. When wrangling with file size versus image quality, it's
often important to minimize the bit depth of an image while
maximizing the number of colors. To calculate the maximum number of
colors for an image of a particular bit depth, remember that the
number of colors is equal to two to the power of what the bit depth
is. For example, a GIF can support up to eight bits per pixel, and
therefore can have as a many as 256 colors, since two to the power
of eight equals 256
Bevel
Adding a beveled effect to a graphic image gives
the image a raised appearance by applying highlight colors and
shadow colors to the inside and outside edges.
Bitmap graphic
This is a graphic image which is composed of a
pattern of dots. The individual dots are stored as data on a
computer. An example of an animation that is a bitmap graphic is a
GIF animation.
Bitmap Image (bmp)
A graphic image stored as a specific arrangement
of screen dots, or pixels. Web graphics are bitmap images. A graphic
which is defined by specifying the colors of dots or pixels which
make up the picture. Also known as raster graphics. Common types of
bitmap graphics are GIF, JPEG, Photoshop, PCX, TIFF, Macintosh
Paint, Microsoft Paint, PNG, FAX formats, and TGA.
Bleed or Bleeding Edge
When a page or a cover design extends to and off
the edge of the paper it is called a "bleed". In print design, the
artwork or block of color must extend off the edge of the page. The
artwork or block of color is then printed on larger-size paper. Then
the printed page is trimmed to the desired size. (add an
illustration)
Bookmark
Just as a paper bookmark is used as a reminder of
the page you are on in a book, electronic bookmarks are used to
bring you back to a web site or other site you may want to return
to. The Netscape browser lets you bookmark any site and save the
bookmarks in a file you can recall at any time. Microsoft Internet
Explorer uses the term "favorite" instead of bookmark for the same
concept.
Browser
The software used to view, manage, and access web
pages by interpreting hypertext and hyperlinks. The two most common
browsers are Netscape and Microsoft Internet Explorer. Web pages
often appear differently depending on the brand and version of the
browser intended to view them in.
