Review Questions From The Book and From the Quiz

QuestionAnswer
Which layer determines the availability of communicating partners along with the resources necessary to make the connection, coordinates partnering applications, and forms a consensus on procedures for controlling data integrity and error recovery? Application Layer
Which layer is responsible for converting data packets from the Data Link layr into electrical signals? Physical Layer
At which layer is routing implemented, enabling connections and path selection between two end systems? Network Layer
Which layer defines how data is formatted, presented, encoded, and converted for use on the network? Presentation Layer
Which layer is responsible for creating, managing, and terminating sessions between applications? Session Layer
Which layer ensures the trustworthy transmission of data across a physical link and is primarily concerned with physical addressing, line discipline, network topology, error notification, ordered delivery of frames, and flow control? Data Link Layer
Which layer is used for reliable communication between end nodes over the network and provides mechanisms for establishing, maintaining, and terminating virtual circuits; transport-fault detection and recovery; and controlling the flow of information? Transport Layer
Which layer provides logical addressing that routers will use for path determination? Network Layer
Which layer specifies voltage, wire speed, and pinout cables and moves bits between devices? Physical Layer
Which layer combines bits into bytes and bytes into frames, use MAC addressing, and provides error detection? Data Link Layer
Which layer is responsible for keeping the data from different applications separate on the network? Session Layer
Which layer is represented by frames? Data Link Layer
Which layer is represented by segments? Transport Layer
Which layer is represented by packets? Network Layer
Which layer is represented by bits? Physical Layer
Put the following in order of encapsulation: Packets Frames Bits Segments Segments Packets Frames Bits
Which layer segments and reassembles data into a data stream? Transport Layer
Which layer provides the physical transmission of the data and handles error notification, network topology, and flow control? Data Link Layer
Which layer manages device addressing, tracks the location of devices on the network, and determines the best way to move data? Network Layer
What is the bit length and expression form of a MAC address? 48 bits (6 bytes( expressed as a hexadecimal number
This device sends and receives information about the Network Layer Router
This layer crates a virtual circuit before transmitting between two end stations. Transport Layer
This device uses hardware addresses to filter a network. Bridge or switch
Ethernet is defined at these layers. Data Link and Physical
This layer supports flow control, sequencing, and acknowledgement. Transport Layer
This device can measure the distance to a remote network. Router
Logical addressing is used at this layer. Network Layer
Hardware addresses are defined at this layer. Data Link Layer
This device creates one big collision domain and one large broadcast domain. Hub
This device creates many smaller collision domains, but the network is still one large broadcast domain. Switch or bridge
This device can never run full duplex. Hub
This device breaks up collision domains and broadcast domains. Routers
