data transfer (bandwidth)
Data transfer, or bandwidth, is the total amount of information downloaded from your web site. Whenever a visitor comes to your site, our web servers send data to your visitor's computer. This data may include web pages, images, videos, sound files, software programs, or compressed files — anything on your site that can be viewed or downloaded. The more visitors you have, and the more complex your web site, the more data transfer you need. Our Yahoo! Web Hosting plan includes unlimited data transfer.

Directions
Directions is an add-on available to all users that allows you display a Yahoo! Directions search box on your web site. When you set up Directions, you enter a destination address and create a directions box; your site visitors can enter their own addresses into the box and click a button to generate directions to the address you specified. You can use Directions to provide a personalized way for your visitors to locate your business or other destination.

directory
A directory is a collection of files and other directories (or subdirectories) often called a folder. You'll find elements on your computer gathered into folders with such names as My Documents or My Computer, each of which can contain many subdirectories, or subfolders. As you build your web site, you will create directories containing your web site files; you can view, create, and delete these directories in the File Manager. You'll recognize directories there (and on your PC) by their corresponding folder-shaped icons.

disk space
The text, images, sound and video files, and other elements that make up your web site occupy storage space on a Yahoo! server. Each Web Hosting plan includes storage room, or disk space, measured in megabytes. Yahoo! Web Hosting now includes unlimited disk space.

domain name (web address)
A domain name is also called a web address, and like a memorable street address, it can help people find you online. You might base your domain name on your own name, the name of your company, keywords that describe your business, even a short phrase — anything that will make your web address easy to remember. When you sign up for a Small Business plan, you can select a new domain name or use one you already own. Learn more.

drag-and-drop
Drag-and-drop is an editing feature that allows you to move an object or other element on your screen by simply clicking on it with your mouse, moving your mouse to the new desired location ("dragging"), and letting go of the mouse button ("drop"). Both Yahoo! PageBuilder and Yahoo! SiteBuilder support this intuitive method of page editing.

Dreamweaver
Macromedia Dreamweaver is a site building and publishing tool appropriate for intermediate to advanced users that allows you to create and edit web pages and applications using a graphical interface and built-in advanced design and coding features. Yahoo! makes it easy to use Dreamweaver with your Web Hosting account. (Please note that Dreamweaver and other third-party software must be purchased separately from Yahoo! Web Hosting.) Learn more.
