In what situation would you need a Crossover Cable?
When connecting like device to like device.
Switch to Switch, Router to Router, etc.
Three components of a Fiber Optic Cable (From Outside to Inside)
- Buffer (or Coating)
- Cladding
- Core
Two Fiber Types
- Single-Mode Fiber
2. Multi-Mode Fiber
Four Characteristics of Multi-Mode Fiber
- LED Transmitter
- Lower Bandwidth and Speed
- Shorter Distances
- Less Expensive
Four Characteristics of Single-Mode Fiber
- Laser Transmitter
- Higher Bandwidth and Speed
- Longer Distances
- More Expensive
What media uses an LC connector, and in what kind of environment?
Fiber Optic Cables, In enterprise equipment and commonly used on SFP Modules.
What media uses an SC connector, and in what kind of environment?
Fiber Optic Cables, for enterprise equipment

What is an SFP
Small Form-factor Pluggable module. It is a hot-pluggable I/O device that plugs into module sockets.
Max speed of SFP module
1 Gbps
Max speed of SFP+ module
10 Gbps
What technology has replaced cross-over cables

List the parts of a typical Ethernet Frame Field
- Preamble
- Destination MAC Address
- Source MAC Address
- Type
- Payload
- FCS
Three major types of LAN communication
- Unicast
- Broadcast
- Multicast
Number of bits in a MAC address
48
Number of Hexadecimal digits in a MAC address
12
Define OUI
Organizationally Unique Identifier.
- The first half of a MAC address. This is unique to a manufacturer and is regulated by the IEEE.
What is included in the second half of a MAC address?
The 24 bit, vendor assigned, end-station address.
-The portion of the MAC address that uniquely identifies the Ethernet Hardware.
Define CAM
Content-Addressable Memory.
- Where the MAC address table is stored.
What is a I/G Address bit?
Individual/Group address bit.
- aka a Broadcast or Multicast bit.
When the least significant bit in the first octet of the MAC address is 1, it indicates that the frame is destined for all or a group of end stations.
What is a U/L Address bit?
Universally or Locally administered address bit.
- It is the second least significant bit of the first octet of the MAC address. If it is set to 1, it means that the MAC has been modified locally.
