Networking Week 2

The TCP/IP model Application layer

• Uses packet sequencing and application mapping through port numbers

• Represents data to the user plus encoding and dialog control

• Controls the hardware devices and media make up of the network

• 
  Determines the best path through the network

The TCP/IP model Internet layer

• Uses packet sequencing and application mapping through port numbers

• Represents data to the user plus encoding and dialog control

• 
  controls the hardware devices and media make up of the network

• 
  Determines the best path through the network

The TCP/IP model Network Access layer

• Uses packet sequencing and application mapping through port numbers

• Represents data to the user plus encoding and dialog control

• controls the hardware devices and media make up of the network

• Determines the best path through the network

The TCP/IP model Transport layer

• 
  Uses packet sequencing and application mapping through port numbers

• Represents data to the user plus encoding and dialog control

• controls the hardware devices and media make up of the network

• 
  Determines the best path through the network

When a server responds to a web request, what occurs next in the encapsulation
process after the web page data is formatted and separated into TCP segments?

• The client decapsulates the segment and opens the web page.

• The client adds the appropriate physical address to the segments so that the server
  can forward the data.

• 
  The server converts the data to bits for transport across the medium.

• The server adds the source and destination IP address to each segment header to
  deliver the packets to the destination.

• The server adds the source and destination physical addresses to the packet header.

Which of the following are true about LANs and WANS? (Choose two.)

• LANs connect groups of networks using ISPs.

• LANs consist of hosts communicating with logical addresses.

• WANS connect groups of networks using TSPs

• WANS connect LANs

• Hosts on a LAN use physical addressing to communicate.

Which of the following is associated with the OSI Network Layer (Layer 3)?

• IP address

• Frames

• MAC address

• 
  Physical addressing
