OSI Model technologies definition of terms

OSI Model Technologies

DNS: Domain Name Service Application: An Hierarchical naming service based on an IPS address that covers computers, services and other resources.
HTTP: Hypertext Transport model: Data transfer protocol used to access websites on word wide web.
SMTP: Simple Mail Transfer Protocol. Protocol to send emails over IP based networks.
TELNET: Protocol that allows a user to log on to another computer within the same network. Uses text commands. SSH is the next generation
FTP: File Transfer Protocol. Allows data/files to be upload to another computer. Uses port 20.

TCP: Transport Control Protocol: Sets up handshaking protocol between 2 systems to allow for communication to take place.
SIP: Session Initiation Protocol: Opens, manages and closes communication paths for multimedia messages such as audio and video. Establishes call with IP and ports.
RTP: Real Time Transport Protocol. Communication standard for video streaming and video conference calls. Can only function once SIP is established. Basis for VOIP.
RPC: Remote Procedure Call. Allows one computer to send commands to another computer. i.e. Teamviewer or RDC
SOCKET: Interface between Application and network layer.

TCP: Transport Control Protocol: As standard system for tagging text with font colour and hyperlink information.
UDP: User Datagram Protocol. A connectionless protocol that is used as an alternative to TCP. Requires low latency and less data loss tolerance.
SCTP: Stream Control Transmission Protocol. Next generation TCP that handles multiple streams of data (voice and other data) at the same time. Can not verify data arrival.
SSL: Secure Sockets Layer. Encrypts data transmitted over the internet.
TLS: Transport Layer Security. Next generation SSL that encryptd dta between 2 end points.

IP: Internet Protocol: Connectionless protocol that insert and address and routing information into data packets.
ARP: Address Resolution Protocol. Broadcasts known IP address to request corresponding MAC address to confirm destination.
IPSEC: Internet Protocol Security. A suite of tools that encrypt and secure transmissions over the internet.
ICMP: Internet Control Message Protocol. Reports on message status including errors, routing and troubleshooting. Main use is PING.
IGMP: Internet Group Management Protocol. Used to establish and maintain membership broadcasts. Noticeboards etc.
OSPF: Open Shortest Path First. Analyses Network to determine the best route with the least hops based on router status.

Ethernet: Computer technologies that work over a LAN, WAN or MAN network. Allows several devices to communicate and prevents collisions of simultaneous data.
802.11: Family of specification for Wireless LAN connections.
MAC/LLC: Media Access Control/Logic Link control . A sublayer that allows multiplexing of a number for different network protocols.
VLAN: Virtual Local Area Network. Software emulated Network that allows different LANs to communicate.
ATM: Asynchronous Transfer Mode. Switching technology used over telecommunication networks that uses multiplexing to send small data packets. ATM
Fibre Channel: High speed lossless transfer data transfer usually between storage media and servers using light.
HDLC: Higher Data Link Control. Point to multi-poin connection using master slave relationship. Old technology superseded by PPP
PPP: Point to Point Protocol: Allows 2 nodes to communicate directly without the need of a host. i.e. Routers and trunks calls.
Token Ring: A local Area Network when the node can only communicate if it has a sequence key to forward on to the next node.

RS-232: Computer technologies that work over a LAN, WAN or MAN network. Allows several devices to communicate and prevents collisions of simultaneous data.
100 BASE-TX: Cabling protocol that allows data transfer speeds of a gigabyte per second. Comes under IEEEE 802.3ab protocol standard.
SDH: Synchronous Digital Hierarchy. International standard data transfer by light emitting diodes. Fibreoptic.
DSL: Digital Subscriber Line (Asymmetric). Data transfer over telephone lines. Up o 1 gig to consumer.
802.11: Family of specification for Wireless LAN connections.
