Flashcards in Common Networking Protocols Deck (19):

What is TCP?

Transfer control protocol. Breaks data into manageable packets and tracks information such as source and destination of packets. Able to reroute packets and is responsible for guaranteed delivery of the data.


What is IP?

Internet protocol. Connectionless protocol, which means that a session is not created before sending data. IP is responsible for addressing and routing of packet between computers.


What is UDP?

User Datagram Protocol. A Connectionless, datagram service that provides and unreliable, best-effort delivery.


What is ICMP?

Internet control message protocol. Enables systems on TCP/IP network to share status and error information such as with the use of PING and TRACERT utilities.


What is SMTP?

Simple mail transfer protocol. Used to reliably send and receive mail over the internet.


What is FTP?

File transfer protocol. Used for transferring files between remote systems. Must resolve host name to IP address to establish communication. It is connection oriented.


What is TFTP?

Trivial file transfer protocol. Same at FTP but not connection oriented.


What is ARP?

Address resolution protocol. Provides IP-address to MAC address resolution for IP packets. A MAC address is your computers unique hardware number. Each computer stores an ARP cache of other computers ARP-IP combinations.


What is POP3?

Post office protocol. A POP3 mail server holds mail until the workstation is ready to receive it.


What is IMAP?

Internet message access protocol. A standard protocol for accessing e-mail from your local server. IMAP is a client/server protocol in which e-mail is received and held for you by your internet server.


What is TELNET?

Provides a virtual terminal or remote login across the network that is connection based. The remote server must be running a telnet service for clients to connect.


What is HTTP?

Hypertext transfer protocol. Set of rules for exchanging files on the World Wide Web. It is the protocol controlling the transfer and addressing of HTTP requests and responses.


What is HTTPS?

Signifies that a web page is using the secure sockets layer (SSL) protocol and is providing a secure connection. This is used for secure internet business transactions.


What is NTP?

Network time protocol. Used to synchronize computer clock times in a network of computers.


What is SNMP?

Simple network management protocol. Monitors status information on a network. Can be used to monitor any device that is SNMP compatible. The agents report info back to the management systems.


What is SIP?

Session initiation protocol. Signaling protocol widely used for controlling multimedia communication sessions such as voice and video sessions over internet protocol (IP). Could include video conferencing and online games. Can create modify and terminate two part (unicast) and multi party (multicast) sessions.


What is RTP?

Real-time transfer protocol. Audio and video protocol standard used to deliver content over the internet. Used in conjunction with other protocols.


What is IGMP?

Internet group management protocol. Used to establish internet protocol (IP) multicast groups. IP hosts and adjacent multicast routers use IGMP to establish multicast group membership. Only needed for IPv4 networks.


What is TLS?

Transport layer security. Cryptographic protocol that provides security for communications over networks such as the internet. TLS and SSL encrypt the segments of network connections at the the transport layer end to end.
