Short for favorites icon, a favicon is a small (16x16 or 32x32 pixel) custom graphic designed to fit next to the URL in the address bar of web browsers.

Favicons are commonly designed to match the logo or theme of its website, and are visible in otherwise hidden browser tabs and favorite lists for quick, visual identification. In Internet Explorer 5+ and Opera, favicons can be dragged to the computer desktop to function as a shortcut.

Placed in the root directory of a website, favicons are generally named favicon.ico, with the following added to the head of web pages:

<link rel="shortcut icon" href="http://example.com/favicon.ico">

It is good practice to add a favicon to a website, both for usability, and to minimize 404 entries in server logs when it in non-existent.

File Transfer Protocol

("FTP server" redirects here)

File Transfer Protocol (FTP) is a network protocol used for uploading and downloading files between computers.

To access files on a web server, an FTP client is the standard tool used by site owner or developers.

To gain access, or log in to an FTP server, 4 pieces of information are needed:

  • FTP address (often, the address of the website)
  • Username
  • Password
  • Port (Default FTP port is 21 - usually not included with FTP login information)


Adobe Flash (formerly Macromedia Flash) is multimedia software platform used for the development of rich-media animations, graphics, and other applications. Flash is commonly used to add animated effects and ads to websites, but is declining in use, in favour of the more web accessible HTML5.

Fragment Identifier

A fragment identifier is a sequence of characters that refers to a specific section within some resource. As part of a web address, a fragment identifier may be added to the section of the URL that follows a hashtag (#), specifying some particular location on a web page. This type of URL is known as a fragment URL or in-page link, for example:


The in-page URL above links to the section of http://www.springboardseo.com/resources/glossary/f.html that has favicon as an ID in its HTML:

<dt id="favicon"><dfn>Favicon</dfn></dt>

Fragment URLS are not seen as duplicate content, and therefore do not require normalization.

Frames (HTML)

HTML frames are an outdated method of structuring web pages that allow sections of the layout to load independently from the rest. Frames can seem like a convenient solution to inexperienced web designers, allowing navigation menus to remain static as the rest of a web page scrolls. However, frames pose a number of usability problems that outweigh their benefits.

Problems With Frames

  • Not always search engine-friendly
  • Not shareable or bookmark-friendly URLs
  • Inaccessible to screen readers and other assistive technology for the visually impaired
  • Not print-friendly
  • Inconsistent cross-browser compatibility

HTML Frame Alternatives

Since the time HTML frames were introduced, other, more efficient technologies have been introduced and refined, and serve as far better solutions. These include:

FTP client

An FTP client is an indispensable tool for webmasters, used to access files on an FTP server, using the File Transfer Protocol.

Instead of displaying the contents of a website, as with a HTTP web browser, an FTP client allows website owners and administrators to download and upload web pages, and other other web files, for website maintenance.

Many FTP clients are available for Windows, Mac, and Linux operating systems. FileZilla is a free, fast, easy to use, and full-featured FTP client that works on all platforms. Available for download at https://www.filezilla-project.org/
