Front Back
A standard method or format for communication between network devices. Ensures that data are transferred whole, in sequence, and without error from one node on the network to another.
Protocol
An Application layer protocol that formulates and interprets requests between Web clients and servers
HTTP (Hypertext Transfer Protocol)
A core protocol in the TCP/IP suite that operates in the Network layer of the OSI model and provides information about how and where data should be delivered. It is the subprotocol that enables TCP/IP to internetwork
IP (Internet Protocol)
A core protocol in the TCP/IP suite that belongs to the Network layer of the OSI model. It obtains the MAC (physical) address of a host, or node, and then creates a local database that maps the MAC address to the host's IP (logical) address.
ARP (Address Resolution Protocol)
An Application layer protocol in the TCP/IP suite that uses a central list of IP addresses, and their associated devices' MAC addresses to assign IP addresses to clients dynamically. It was the precursor to DHCP.
BOOTP (Bootstrap Protocol)
An Application layer protocol in the TCP/IP suite that manages the dynamic distribution of IP adresses on a network. Using this protocol to assign IP addresses can nearly eliminate duplicate-addressing problems
DHCP (Dynamic Host Configuration Protocol)
An Application layer protocol used to send and receive files via TCP/IP
FTP (File Transfer Protocol)
A core protocol in the TCP/IP suite that notifies the sender that something has gone wrong in the transmission process and that packets were not delivered
ICMP (Internet Control Message Protocol)
A TCP/IP protocol used to manage multicast transmissions. Routers use this protocol to determine which nodes belong to a multicast group, and nodes use this protocol to join or leave a multicast group
IGMP (Internet Group Management Protocol or Internet Group Multicast Protocol)
An Application layer protocol in the TCP/IP suite that facilitatesthe exchange of newsgroup messages, or articles, between multiple servers and users
NNTP (Network News Transfer Protocol or Network News Transport Protocol)
A simple Application layer protocol in the TCP/IP suite used to synchronize the clocks of computers on a network. This protocol depends on UDP for Transport layer services
NTP (Network Time Protocol)
A core protocol in the TCP/IP suite that belongs in the Network layer of the OSI model. This protocol relies on a database table to associate the IP (logical) address of a node with its MAC (physical) address. It can be used to supply IP addresses to diskless workstations.
RARP (Reverse Address Resolution Protocol)
A core protocol of the TCP/IP suite. It belongs to the Transport layer and provides reliable data delivery services
TCP (Transmission Control Protocol)
A suite of networking protocols that includes TCP, IP, UDP and many others. It provides the foundation for data exchange across the Internet.
TCP/IP (Transmission Control Protocol/Internet Protocol)
A terminal emulation protocol used to log on to remote hosts using the TCP/IP protocol. This protocol resides in the Application layer of the OSI model.
