Which of the following organizations developed the Open System Interconnection model?
International Organization for Standardization(ISO)
Identify the layer of the Open System Intorconnection (OSI) model that controls the transmission, reception, and addressing of frames. Also Identify the channel access method that Ethernet uses.
Data-link layer; CSMA/CD
The generation, by a receiving system, of messages that instruct the sending system to speed up or slow down its transmission
Flow control
The transmission of a return messages by the recipient to verify the receipt of a packet of packets
Packet Acknowledgement
The division of lengthy data streams into segments sufficiently small enough for transmission over the network
Segmentation
The retransmission of packets that have been garbled or lost in transit
Error Correction
The inclusion in a packet of special codes used by the receiving system to verify that the content of the packet wasn't damaged in transit
Error detection
OSI model
Physical, Data-link, Network, transport, session, Presentation, Application
Identify the two main Media Access Control (MAC) mechanisms used in today's local area networks (LANs).
Carrier Sense Multiple Access with Collision Detection (CSMA/CD)

Token passing
Identify two potential problems with using packet switching on a network.

What layer of the Open Systems Interconnection (OSI) model defines the medium, network interfaces, connecting hardware, and signaling methods used on a network?
Physical
Which layer of the Open Systems Interconnection (OSI) model adds both a header and footer (creating a frame) to the information that is passed down from an upper layer?
Data link
What layer of the Open Systems Interconnection (OSI) model is responsible for the logical addressing of end systems and the routing of datagrams on a network?
Network
What layer of the Open Systems Interconnection (OSI) model typically provides either connectionless or connection-oriented services to applications?
Transport
What layer of the Open Systems Interconnection (OSI) model is responsible for dialog control between two communicating end systems?
