  1. What is TCP.
    TCP breaks data into manageable packets and tracks information such as source and destination ofpackets. It is able to reroute packets and is responsible for guaranteed delivery of the data.
  2. what is UDP ?
    A connectionless, datagram service that provides an unreliable, best-effort delivery.
  3. What is ICMP ? 
    Internet Control Message Protocol enables systems on a TCP/IP network to share status and error information such as with the use of PING and TRACERT utilities
  4. What is FTP ? 
    File transfer protocol is used for transferring files between remote systems. Must resolve host nameto IP address to establish communication. It is connection oriented (i.e. verifies that packets reachdestination).
  5. What is TFTP ? 
    TFTP - Same as FTP but not connection oriented.
  6. What is ARP ? 
    provides IP-address to MAC address resolution for IP packets. A MAC address is your computer'sunique hardware number and appears in the form 00-A0-F1-27-64-E1 (for example). Each computer storesan ARP cache of other computers ARP-IP combinations.
  7. What is IGMP ? 
    Internet Group Management Protocol is used to manage Internet Protocol multicast groups. IPhosts and adjacent multicast routers use IGMP to establish multicast group memberships. IGMP is onlyneeded for IPv4 networks, as multicast is handled differently in IPv6 networks.
  8. What is SIP ? 
    Stands for Session Initiation Protocol and is a signaling protocol, widely used for controllingmultimedia communication sessions such as voice and video calls over Internet Protocol (IP). Other feasibleapplication examples include video conferencing, streaming multimedia distribution, instant messaging,presence information and online games. The protocol can be used for creating, modifying and terminatingtwo-party (unicast) or multiparty (multicast) sessions consisting of one or several media streams. Themodification can involve changing addresses or ports, inviting more participants, adding or deleting mediastreams, etc.
  9. What is RTP ?
    Real-time Transport Protocol is the audio and video protocol standard used to deliver content overthe Internet. RTP is used in conjunction with other protocols such as H.323 and RTSP.
  10. What is TLS ?
    Transport Layer Security is a cryptographic protocol that provides security for communications overnetworks such as the Internet. TLS and SSL encrypt the segments of network connections at the TransportLayer end-to-end. Several versions of the protocols are in wide-spread use in applications like webbrowsing, electronic mail, Internet faxing, instant messaging and voice-over-IP (VoIP).
  11. What is SNMP ?
    Stands for Simple Network Management Protocol and is used for monitoring and status informationon a network. SNMP can be used to monitor any device that is SNMP capable and this can includecomputers, printers, routers, servers, gateways and many more using agents on the target systems. Theagents report information back to the management systems by the use of “traps” which capture snapshotdata of the system. This trap information could be system errors, resource information, or otherinformation. The SNMPv2 standard includes enhancements to the SNMPv1 SMI-specific data types, such asincluding bit strings, network addresses, and counters. In SNMPv3 security was addressed. Because all ofthe trap information sent was in clear text, any monitoring information being sent and collected foroperational purposes could also be pulled off the wire by a malicious person
  12. What is NTP ?
    Network Time Protocol is a protocol that is used to synchronize computer clock times in a network ofcomputers.
  13. HTTPS
    Signifies that a web page is using the Secure Sockets Layer (SSL) protocol and is providing asecure connection. This is used for secure internet business transactions.
  14. HTTP
    The Hypertext Transfer Protocol is the set of rules for exchanging files (text, graphic images,sound, video, and other multimedia files) on the World Wide Web. It is the protocol controlling the transferand addressing of HTTP requests and responses
  15. TELNET
    Provides a virtual terminal or remote login across the network that is connection-based. Theremote server must be running a Telnet service for clients to connect.
  16. IMAP
    Like POP3, Internet Message Access Protocol is a standard protocol for accessing e-mail from yourlocal server. IMAP (the latest version is IMAP4) is a client/server protocol in which e-mail is received andheld for you by your Internet server.
  17. POP3
    - Post Office Protocol. A POP3 mail server holds mail until the workstation is ready to receive it.
