Front 5

Offers a synchronized time service to all configured network devices.

Back 5

NTP

Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use.

Front 6

Used to resolve IP addresses to MAC addresses for purposes of local-area message dlivery.

Back 6

ARP

The address resolution protocol (arp) is a protocol used by the Internet Protocol (IP) [RFC826], specifically IPv4, to map IP network addresses to the hardware addresses used by a data link protocol. The protocol operates below the network layer as a part of the interface between the OSI network and OSI link layer.

Front 7

Manages the initiation of VoIP phone services.

Back 7

SIP

The Session Initiation Protocol (SIP) is a communications protocol for signaling and controlling multimedia communication session such as voice and video calls. The most common applications of SIP are in Internet telephony, as well as instant messaging, over Internet Protocol (IP) networks.

Front 8

Offers a secure connection from a virtual terminal to remote devices.

Back 8

SSH

Secure Shell (SSH) is a cryptographic network protocolfor operating network services securely over an unsecured network. The best known example application is for remote login to computer systems by users.

Front 9

Provides for the automatic assignment of IP addresses to hosts on a given network.

Back 9

DHCP

Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers (i.e., a scope) configured for a given network.Dec 6, 2016

Front 10

Provides encryption for data above the transport layer and updates the SSL protocol.

Back 10

TLS

Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), both frequently referred to as "SSL", are cryptographic protocols that provide communications security over a computer network. ... The connection is private (or secure) because symmetric cryptography is used to encrypt the data transmitted.

Front 11

Nonsecure client/server protocol used to retrieve data from web servers to their clients.

Back 11

HTTP

The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text.

Front 12

Used by email servers to deliver email between server systems.

Back 12

SMTP

Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (email) transmission. First defined by RFC 821 in 1982, it was last updated in 2008 with Extended SMTP additions by RFC 5321, which is the protocol in widespread use today.

Front 13

Used to transfer files in a connection-oriented state.

Back 13

FTP

The File Transfer Protocol (FTP) is a standard network protocol used to transfer computer files between a client and server on a computer network. FTP is built on a client-server model architecture and uses separate control and data connections between the client and the server.

Front 14

connection-oriented delivery of upper-layer datagrams using acknowledgments.

Back 14

TCP

The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. ... Internet protocol suite. Application layer.

Front 15

Network layer protocol used by programs such as ping to deliver network connection messages to requesting clients.

Back 15

ICMP

The Internet Control Message Protocol (ICMP) is a supporting protocol in the Internet protocol suite. It is used by network devices, like routers, to send error messages and operational information indicating, for example, that a requested service is not available or that a host or router could not be reached.

Front 16

Offer a secure authentication of clients to web servers before delivery of requested data.

Back 16

HTTPS

(HyperText Transport Protocol Secure) The protocol used to access a secure Web server. When https:// is used as the prefix of a Web address rather than the commonhttp://, the session is managed by a security protocol, which is typically SSL, and the transmission is encrypted to and from the Web server.

Front 17

Often used in audio/video delivery of real-time data requiring QoS and tight sequencing.

Back 17

RTP

The Real-time Transport Protocol (RTP) is a network protocol for delivering audio and video over IP networks. RTP is used extensively in communication and entertainment systems that involve streaming media, such as telephony, video teleconference applications, television services and web-based push-to-talk features.

Front 18

Resoves fully qualified demain names to their unique IP addresses.

Back 18

DNS
