OSI Model Flashcards
Flow control can be found at which layer of the OSI?
The Transport layer is responsible for flow control via the TCP/IP protocols of TCP and UDP.
Which layer of the OSI is responsible for dialogue control of applications?
The Session layer is responsible for offsetting up the dialogue between two hosts.
the layer for logical addressing of network nodes
.The Network layer is responsible for
the layer for framing of data and the physical addressing of local nodes.
The Data Link layer is responsible forthe framing of data and the physical addressing of local nodes.
The layer responsible for setting up the dialogue between two hosts.
The Session layer is responsible for
Which layer is compression and decompression, as well as encryption and decryption.
Presentation layer is responsible for
The logical link control (LLC) sublayer is responsible for
managing access to Network layer protocols
The media access control (MAC) sublayer is responsible for
physical addressing and framing data for the transmission media.
Layer that is responsible for framing data and contains the LLC and MAC sublayers.
he Data Link layer is responsible for
The IEEE 802.2 working group defines the
Logic Link Control (LLC) sublayer of the Data Link layer.
The IEEE 802.3 and 802.11 working groups define the
Media Access Control (MAC) sublayer of the Data Link layer.
The IEEE 802.15 working group defines
wireless personal area networks (WPANs).
The concept of transmitting multiple segments before the receiving host acknowledges the data is
windowing.
Sequencing is done with each segment so they can be combined back together at the
Transport layer.
The layer for flow control and creating virtual circuits
The Transport layer
The layer responsible for routing network packets
Network
The layer that is responsible for framing bits
Data Link Layer
the IEEE standard of 802.3 specifies the
carrier sense multiple access/collision detection (CSMA/CD) contention method.
The IEEE standard for 802.5 details the
disbanded Token Ring specification
Which Layer uses port numbers
Transport Layer
Datagrams are routed across which layer?
Network Layer
Which layer applies a header and footer to create an Ethernet frame?
Data Link
Which layer applies a header to create an IP datagram
Network
Which layer applies a TCP or UDP header to create a segment or datagram
Transport
Which layer provides an entry point for applications to access the protocol stack?
Application
Which is the only layer that adds a header and a footer to data?
Data Link
Internet Message Access Protocol (IMAP) operates at which layer?
Application
Which of the OSI model layers is responsible for syntax translation and compression or encryption?
Presentation Layer
Hypertext Transfer Protocol (HTTP) and Simple Network Management Protocol (SNMP) operate at the
Application layer.
Internet Control Message Protocol (ICMP) and Internet Group Management Protocol (IGMP) both operate at the
Network layer.
User Datagram Protocol (UDP) operates at the
Transport Layer
Internet Control Message Protocol (ICMP) operates at the
Network layer by sending operational and error messages
Address Resolution Protocol (ARP) does not encapsulate upper layer protocol data, but it is a
Data link layer protocol.
the following devices enables two computers to communicate when they are using different protocols at each layer
Gateway
IP address filtering operates at whch layer
Network
Hubs operate at which layer
Physical
Switches operate at which layer
Data Link
Proxy servers operate at which layer of the OSI reference model
A proxy server is an Application layer service because it receives Internet service requests from client computers, reads the Application layer protocol data in each request, and then generates its own request for the same service and transmits it to the Internet server the client specifies.
