In an Ethernet frame, what is the Preamble?

Ethernet Fundamentals

In an Ethernet frame, what is SFD?

Start Frame Delimiter

Signifies that the next byte begins the Destination MAC field

Ethernet Fundamentals

In an Ethernet frame, what is Lenght & what is Type?

Lenght pertains to the data field

Type pertains to the type of protocol listed inside the frame

Which cable is used between PC and router?

Crossover

----------------------------------------------

Straight-Through Cable
A straight-through cable is the standard network cable connection and is used to connect the source and destination computers through an internetworking device. Specifically, you can use it to connect a host to a hub or switch

Crossover Cable
In a crossover cable, the standard RJ-45 cable between the source and destination computers is cross-connected. A crossover cable can be used to connect:

• Two computers
• Two hubs
• A hub to a switch
• A cable modem to a router
• Two router interfaces
