Total Transmission Time Equation - Answers Length of packet(L)/Transmission Rate(R) +
Distance(d)/Propagation Speed(s)
Packet Switching vs. Circuit Switching - Answers -Circuit switching uses dedicated links/paths but packet
switching does not use any dedicated links/paths
-Circuit switching does not have congestion problems, but packet switching my have congestion
problems
(packet switching has queueing and packet loss problems)
Network Protocols - Answers (His Def)
Set of rules which help the end systems to communicate with each other in efficient manner
(Other Def)
The software defining the rules and formats a computer must use when sending information across the
network.
Example of network protocols - Answers Hypertext Transfer Protocol(HTTP)
Transmission Control Protocol(TCP)
Internet Protocol (IP)
Examples of Access Networks - Answers Digital Subscriber Line(DSL)
, Cable Access Network
Home Access Network
Enterprise Access Network
Wireless Access Network
Forms of Physical Media - Answers Coax Cable, Twisted Pair, Fiber optics, Satellite
Guide v Unguided Media - Answers Guided: Data travels through something physical
Unguided: Data travels in open space
Equation for transmission delay - Answers L/R
L = Length of packet
R = transmission rate
FDM v TDM - Answers -FDM allows users to have stable connection (up/down link) throughtout the time
of use, while TDM only allows user to process their data during their time.
-FDM has a limited # of users depend on capacity frequency that transmission media offers, while TDM
can have unlimited users but each will have to wait longer to process their data
Application Layer - Answers The seventh layer of the OSI model. Application layer protocols enable
software programs to negotiate formatting, procedural, security, synchronization, and other
requirements with the network.
Network Layer - Answers The third layer in the OSI model. Protocols in this layer translate network
addresses into their physical counterparts and decide how to route data from the sender to the receiver.
Link Layer - Answers Fourth layer in the TCP/IP stack. This layer adds MAC address of the sender and the
recipient.
data transfer between neighboring networks
Physical Layer - Answers The lowest, or first, layer of the OSI model. Protocols in this layer generate and
detect signals so as to transmit and receive data over a network medium. These protocols also set the
data transmission rate and monitor data error rates, but do not provide error correction.
