Study Notes
Switch Functionality
- A switch connects multiple cable segments or devices and forwards frames to the appropriate segment based on MAC addresses.
Signal Regeneration
- Repeater and hub devices regenerate signals and send them out all connected ports without examining packet contents.
Learning Devices Location
- Switches and bridges learn device locations by copying the source MAC address from frame headers upon receiving frames.
Frame Handling
- An 8-port switch sends frames addressed to unknown devices out of all other ports except the one it was received on.
Network Segmentation
- Hubs do not segment the network, functioning instead as a simple connector for devices.
Signal Sending Device
- A transceiver is the device that sends signals from a computer onto a network.
Media Type Modification
- Switches can use Small Form-factor Pluggable (SFP) or Gigabit Interface Converters (GBIC) modules to change media types on switch ports.
MAC Address Discovery
- Address Resolution Protocol (ARP) is utilized to discover the MAC address of a destination device when the IP is known but the hardware address is not.
Connecting Different Media Types
- A media converter is necessary to connect a server with a 100BaseFX network interface card to a switch that only has 100BaseTX ports.
OSI Model Layer for Converters
- Media converters operate at Layer 1 of the OSI model.
Network Interface Card Role
- A network interface card connects a device to transmission media, enabling data sending and receiving.
MAC Address Characteristics
- A MAC address is a 48-bit unique identifier typically represented in hexadecimal format.
Valid MAC Address Example
- An example of a valid MAC address is AB.07.CF.62.16.BD.
Modem Functionality
- Modems modulate digital data from PCs into analog for transmission over telephone networks and demodulate incoming analog signals back into digital data.
Additional MAC Address Example
- Another example of a MAC address is C0-34-FF-15-01-8E.
Router Functionality
- Routers link multiple networks together and manage traffic direction between them.
