17. SMTP – Simple Mail Transfer Protocol
– An Internet standard for email transmission across IP networks.
18. POP3 – Post Office Protocol 3
– A protocol used by local email clients to retrieve emails from a remote server over a TCP/IP connection.
19. IMAP – Internet Message Access Protocol
– An Internet standard protocol used by email clients to retrieve messages from a mail server.
20. SSH – Secure Shell
– A cryptographic network protocol for operating network services securely over an unsecured network.
21. VoIP – Voice over Internet Protocol
– A technology that allows you to make voice calls using a broadband Internet connection instead of a regular phone line.
22. RTP – Real-time Transport Protocol
– A protocol designed for end-to-end, real-time, transfer of streaming media.
23. SNMP – Simple Network Management Protocol
– An Internet-standard protocol for collecting and organizing information about managed devices on IP networks.
24. ARP – Address Resolution Protocol
– A protocol used for mapping an IP address to a physical machine address that is recognized in the local network.
25. RARP – Reverse Address Resolution Protocol
– A protocol used by a host computer to request its IP address from an administrative host, when only its link layer address is known.
26. BGP – Border Gateway Protocol
– A standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems on the Internet.
27. OSPF – Open Shortest Path First
– A routing protocol for Internet Protocol (IP) networks that uses a link state routing algorithm.
28. VLAN – Virtual Local Area Network
– A group of host computers and servers that are configured as if they are on the same LAN, regardless of their physical location.
29. MPLS – Multiprotocol Label Switching
– A technique in high-performance telecommunications networks that directs data from one network node to the next based on short path labels.
30. QoS – Quality of Service
– The description or measurement of the overall performance of a service, such as telephony or computer networking.
31. SDN – Software-Defined Networking
– An approach to networking that uses software-based controllers or application programming interfaces to communicate with underlying hardware infrastructure.
32. NFV – Network Functions Virtualization
– The concept of replacing dedicated network appliances with software running on commercial off-the-shelf hardware.
33. ICMP – Internet Control Message Protocol
– A supporting protocol in the Internet Protocol Suite used by network devices to send error messages and operational information.
34. IGMP – Internet Group Management Protocol
– A communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships.
35. SSID – Service Set Identifier
– A sequence of characters that uniquely names a wireless local area network (WLAN).
36. MAC – Media Access Control
– A sublayer of the data link layer in the OSI model, responsible for the transmission of data packets to and from the network-interface card.
37. CSMA/CD – Carrier Sense Multiple Access with Collision Detection
– A network protocol for carrier transmission that operates in the medium access control layer.
38. CSMA/CA – Carrier Sense Multiple Access with Collision Avoidance
– A network protocol for carrier transmission that avoids collisions by using a method of transmitting packets that requires the transmitter to first sense the presence of a signal carrier.
39. GPRS – General Packet Radio Service
– A packet-oriented mobile data standard on the 2G and 3G cellular communication networks.
40. EDGE – Enhanced Data rates for GSM Evolution
– A digital mobile phone technology that allows improved data transmission rates as a backward-compatible extension of GSM.
