Group A
Transmit on 1, 2 and receive on 3, 6:
PC NICs
Routers
Wireless Access Points (Ethernet Interace)
Networked Printers
Group B
Transmits on 3, 6 and receive on 1, 2:
Hubs
Switches
You'll need a straight-though cable between Group A and Group B
You'll need a crossover cable between any devices belonging to the same group

Seven Layers:
7. Application
6. Presentation
5. Session
4. Transport
3. Network
2. Data-link
1. Physical
Application: acts as the interface between the software and the network
Presentation: defines and negotiates data formats and also Encryption
Session: defines how to start, stop and control conversations
Transport: data-delivery and data-recovery
Network: Logical addressing, routing and path determination
Data-link: defines the format of the header and the trailer
Physical: deals with standards from other organizations, physical characters of transmission mediums.

Data Encapsulation is a 5-step process in TCP/IP Protocol Architecture
Starts at :
Application layer ->
Transport layer ->
Internet Layer ->
Network access layer ->
Transmission of bits occurs
Remember:
Network access layer - Frame
Internet layer - Packet
Transport layer - Segment

Remember:
Each layer provides a service to the layer above it.
There are four layers:
1. Application. Example: HTTP, POP3, SMTP
Acts as the interface between the software running on a computer and the network.
Most common example is the Browser
2. Transport. Example: TCP, UDP
TCP provides a mechanism to guarantee data delivery by using a data-recovery feature.
3. Internet. Example: IP
IP defines addresses so that each host can be found and data can be delivered to it.
4. Network Access. Example: Ethernet, Frame Relay.
Defines the protocols and Hardware required to deliver data across the network.
Remember:
Same-layer Interaction on different computers
Adjacent-layer Interaction on same computer
Each layer provides a service to the layer above it.
