- Personal Information Exchange (PFX)
The PFX protocol allows applications to transfer certificates and other personal information from one computer to another computer, floppy disk, or smart card.

- Platform for Internet Content Selection (PICS)
PICS describes a scheme for rating content over the Internet, using labels (meta data). PICS standards are established by a cross-industry working group, and facilitate self-rating, third-party rating, and ease of use in controlling access to content on the Internet. See
http://www.w3.org/PICS/ 
for more information.
- Pluggable protocol
Pluggable protocols provide the capability to create custom URL protocols. Microsoft Internet Explorer uses two mechanisms for registering new URL protocol handlers: (1) to register a URL protocol and its associated application so that all attempts to navigate to a URL using that protocol launch the application
(for example, registering applications to handle mailto: or news: URLS); (2) to use the Asynchronous Pluggable Protocols API, which allows you to define new protocols by mapping the protocol scheme to a class, by permanently registering an asynchronous pluggable protocol handler in the registry, by permanently or temporarily registering a pluggable name space handler, or by permanently or temporarily registering a MIME filter.
- Positioning
In HTML, elements on a Web page "flow" one after the other in the order that they appear in the HTML source. By applying a small set of Cascade Cascading Style Sheets (CSS) attributes, the position of HTML elements on a Web page can be specified; with scripting, that position can be dynamically changed on the fly. The CSS attributes allow the author to control the precise position of elements on a page by giving exact coordinates (absolute positioning) or specifying placement relative to the position of other objects on the page, such as graphics.
- Point-to-Point Tunneling Protocol (PPTP)
PPTP is a network protocol that is built upon two well-established Internet communication protocols: Point-to-Point Protocol (PPP) and Transmission Control Protocol/Internet Protocol (TCP/IP). PPTP enables the secure transfer of data from a remote client to a private enterprise server by creating a virtual private network (VPN) across TCP/IP-based networks. Because PPTP supports on-demand, multi-protocol, virtual private networking over public networks, it is able, through the Internet, to use a local call to an Internet Service Provider (ISP) to gain secure access to the corporate network through corporate firewalls. As a result, companies can use PPTP to outsource their remote dial-up needs to an ISP and reduce both cost and complexity.

- Profile Assistant
The Profile Assistant is an Internet Explorer feature that makes it easy for users to share registration and demographic information with Web sites that require information, such as an address or an e-mail address.
A user's information is stored securely in protected storage on the client computer. User privacy is maintained by giving the user complete control over access to their data, and the user avoids having to re-enter the information for each site's registration page.
The Profile Assistant complies with the current Platform for Privacy Preferences (P3P) privacy recommendations set by the World Wide Web Consortium (W3C).
- Proxy Server
- Publishing point
A publishing point is a virtual directory for storing content that is available to clients or for access to a live stream. Users reach a publishing point by using its URL.
