Topic B Explain the TCP/IP Suite
The TCP/IP protocol suite maps to a four-layer conceptual model: _________, _________, _________ , and ________________. This model is referred to as the Internet Protocol Suite, the Department of Defense (DoD) model, or the ARPA model .
Application , Transport , Internet , Link (or Network Interface)
TCP/IP provides two methods of data delivery: ___________ using the Transmission Control Protocol (TCP) ___________the User Datagram Protocol (UDP).
Connection-oriented delivery, Connectionless delivery using
The purpose of __________ is to encourage the development and availability of the Internet. It provides organizational resources to the Internet Architecture Board (IAB)
ISOC (isoc.org)
The __________ provides addressing and routing functions. It also provides the ability to fragment large frames from the ___________ into smaller packets.
Internet (or more precisely Internetwork) layer , Network Interface layer ,
__________—manages allocation o fIP addresses and maintenance of the top-level domain space. IANA is currently runby Internet Corporation for Assigned Names and Numbers (ICANN).
Internet Assigned Numbers Authority (IANA) (iana.org)
__________—focuses on solutions to Internet problems and the adoption of new standards.
Internet Engineering Task Force (IETF) (ietf.org)
The __________ uses several protocols, notably the Internet Protocol (IP) and Address Resolution Protocol (ARP), to facilitate the delivery of packets.
Internet layer
The ____________ is the equivalent of the OSI Physical and Data Link layers. It defines the host's connection to the network media. This layer includes the _____________ involved in the interchange of frames between hosts. The technologies used can be LAN-based (Ethernet or Wi-Fi) or WAN-based (T-carrier, ISDN, or DSL).
Link (or Network Interface) layer , hardware and software
_________ introduces the ability for one host to forward information to another using any available path. A ____________protocol is described as ____ because it can automatically recover from communications link failures. It re-routes data packets around an internetwork of available paths.
Packet switching, packet switching , robust
__________ are procedures or rules used by networked computers to communicate. For communication to take place, the two computers must have a protocol in common. Often, several protocols used for networking are designed to work together. This collection of protocols is known as a _____________ .
Protocols , protocol suite
Several protocol suites have been used for LAN and WAN communications over the years. However, the overwhelming majority of networks have now converged on the use of the ________________. Most network implementations you will be required to undertake will depend on the use of TCP/IP.
Transmission Control Protocol/Internet Protocol (TCP/IP)suite
The ____________—or Host-to-Host layer—establishes connections between the different applications that the source and destination hosts are communicating with. It breaks Application-layer information into segments.
Transport layer
A _____is a dedicated path established between two locations, such as two routers or two modems. The circuit could be permanently available, but in the case of a ____, the routers negotiate a link, then once the connection is established, all communications are forwarded along the same path.
circuit , circuit-switched path
The ____capability of the Internet Protocol to divide large messages into numerous small packets means that a single packet can be resent at relatively little cost if it is lost or damaged during transmission. It also means that the protocol can work with different types of underlying ____ frame formats and sizes.
fragmentation, Data Link protocol
