| comp., MS | File Transfer Protocol | Protocol Trosglwyddo Ffeiliau (A member of the TCP/IP suite of protocols, used to copy files between two computers on the Internet. Both computers must support their respective FTP roles: one must be an FTP client and the other an FTP server) |
| comp., MS | Hypertext Transfer Protocol | Protocol Trosglwyddo Hyperdestun (The Internet protocol used to deliver information over the World Wide Web) |
| comp., MS | Internet Message Access Protocol | Protocol Mynediad Negeseuon Rhyngrwyd (A method computers use to send and receive e-mail messages. It allows you to access e-mail without downloading it to your computer) |
| comp., MS | Internet Protocol | Protocol Rhyngrwyd (A routable protocol in the TCP/IP protocol suite that is responsible for IP addressing, routing, and the fragmentation and reassembly of IP packets) |
| comp., MS | Layer Two Tunneling Protocol | Protocol Twnelu Haen Dau (An industry-standard Internet tunneling protocol that provides encapsulation for sending Point-to-Point Protocol (PPP) frames across packet-oriented media. For IP networks, L2TP traffic is sent as User Datagram Protocol (UDP) messages. In Microsoft operating systems, L2TP is used in conjunction with Internet Protocol security (IPSec) as a virtual private network (VPN) technology to provide remote access or router-to-router VPN connections. L2TP is described in RFC 2661) |
| comp., MS | Lightweight Directory Access Protocol | Protocol Mynediad Cyfeiriadur Ysgafn (The primary access protocol for Active Directory. LDAP is an industry-standard protocol, established by the Internet Engineering Task Force (IETF), that allows users to query and update information in a directory service. Active Directory supports both LDAP version 2 and LDAP version 3) |
| comp., MS | Link Control Protocol | Protocol Rheoli Dolenni (A PPP control protocol that negotiates link and PPP parameters to dynamically configure the data-link layer of a PPP connection) |
| comp., MS | Network News Transfer Protocol | Protocol Trosglwyddo Newyddion Rhwydwaith (A member of the TCP/IP suite of protocols used to distribute network news messages to NNTP servers and clients (newsreaders) on the Internet. NNTP is designed so that news articles are stored on a server in a central database, thus enabling a user to select specific items to read) |
| comp., MS | Online Certificate Status Protocol | Protocol Statws Tystysgrif Ar-lein (A protocol that allows real-time validation of a certificate's status by having the CryptoAPI make a call to an OCSP responder and the OCSP responder providing an immediate validation of the revocation status for the presented certificate. Typically, an OCSP responder responds with the revocation status check request based on the certificate revocation list (CRL) or other forms of revocation status it retrieves from the certification authorities) |
| comp., MS | Point-to-Point Protocol | Protocol Pwynt-i-Bwynt (A set of industry-standard framing and authentication protocols that are included with Windows to ensure interoperability with other remote access software. PPP negotiates configuration parameters for multiple layers of the Open Systems Interconnection (OSI) model. The Internet standard for serial communications, PPP defines how data packets are exchanged with other Internet-based systems using a modem connection. PPP is documented in RFC 1661) |
| comp., MS | Point-to-Point Protocol over Ethernet | Protocol Pwynt-i-Bwynt dros yr Ether-rwyd (A specification for connecting users on an Ethernet network to the Internet through a broadband connection, such as a single DSL line, wireless device, or cable modem. Using PPPoE and a broadband modem, LAN users can gain individual authenticated access to high-speed data networks. By combining Ethernet and Point-to-Point Protocol (PPP), PPPoE provides an efficient way to create a separate connection for each user to a remote server) |
| comp., MS | Remote Desktop Protocol | Protocol Bwrdd Gwaith Pell (A proprietary protocol to provide remote display and input capabilities over network connections for Windows®-based applications between two computers) |
| comp., MS | Session Initiation Protocol | Protocol Cychwyn Sesiwn (A standard signaling protocol for establishing multi-media communications sessions between two or more users over an IP network) |
| comp., MS | Transmission Control Protocol | Protocol Rheoli Trosglwyddo (The protocol within TCP/IP that governs the breakup of data messages into packets to be sent via IP, and the reassembly and verification of the complete messages from packets received by IP) |
| comp., MS | Transmission Control Protocol/Internet Protocol | Protocol Rheoli Trosglwyddo/Protocol Rhyngrwyd (A set of networking protocols widely used on the Internet that provides communications across interconnected networks of computers with diverse hardware architectures and various operating systems. TCP/IP includes standards for how computers communicate and conventions for connecting networks and routing traffic) |
