Chapter 1 Lab 1-1
1. Which layer chooses and 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?
2. Which layer is responsible for
converting data packets from the Data Link layer into electrical signals?
3. At which layer is routing implemented,
enabling connections and path selection between two end systems?
4. Which layer defines how data
is formatted, presented, encoded, and converted for use on the network?
5. Which layer is responsible for
creating, managing, and terminating sessions between applications?
6. 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?
7. 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?
8. Which layer provides logical
addressing that routers will use for path determination?
9. Which layer specifies voltage,
wire speed, and pin-out cables and moves bits between devices?
10. Which layer combines bits into
bytes and bytes into frames, uses MAC addressing, and provides error detection?
11. Which layer is responsible
for keeping different applications' data separate on the network?
12. Which layer is represented
by frames?
13. Which
layer is represented by segments?
14. Which
layer is represented by packets?
15. Which
layer is represented by bits?
17. Put
the following in order of de-encapsulation; packets: frames: bits: segments
