Review Questions From The Book and From the Quiz
Question | Answer |
---|---|
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 |

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 |
