Baseband and broadband are two different methods of transmitting data signals, with the key difference being how they utilize the available bandwidth. Baseband transmits a single data signal at a time using the entire bandwidth of the transmission medium. Broadband, on the other hand, transmits multiple data signals simultaneously over different frequency bands within the same medium.
60
Since the hub is just a repeater that floods everything it gets to everything that's connected -- everything connected to the hub is a collision domain.
the broadcast domain is everything in the network, which is everything under a router. Connected by switches is still in the same network...that only grows the network.
61
In communication systems, simplex, half-duplex, and full-duplex describe the direction(s) of data flow. Simplex is one-way, like a broadcast. Half-duplex allows two-way communication, but only one direction at a time. Full-duplex allows simultaneous two-way communication.
Here's a more detailed breakdown:
1. Simplex:
Data Flow:
One-way communication, like a one-way street. One device transmits, and the other only receives.
Examples:
Radio and television broadcasting, early computer systems with keyboard input and monitor output.
2. Half-Duplex:
Data Flow:
Two-way communication, but only one direction at a time. Devices can both send and receive, but not simultaneously.
Examples:
Walkie-talkies, push-to-talk radios, older network systems (e.g., some older Ethernet connections).
3. Full-Duplex:
Data Flow:
Two-way communication with simultaneous transmission and reception. Devices can send and receive data at the same time.
Examples:
Modern Ethernet networks (most common), telephone systems, some wireless bridges.
In essence:
Simplex is like a one-way road.
Half-duplex is like a road with two lanes, but there's construction so a traffic cop is directing traffic, one side using the same later, one side at a time.
Full-duplex is like a two-lane highway where traffic can flow in both directions simultaneously.
62
The multiplexing divides the capacity of the communication channel into several logical channels, one for each message signal or data stream to be transferred.
divide by
* time
* frequency
* statistical
Multiplexing allows multiple signals to share a single communication channel, increasing efficiency and reducing costs. It works by combining several signals into one composite signal for transmission, and then separating them at the receiving end. This is achieved through various techniques, such as dividing the bandwidth into time slots (TDM) or wavelength bands (WDM).
63
A hub is just...
a repeater that floods out the frames it receives
64
half duplex transmission introduces the concept of what?
collision domains
65
hubs operate at what layer?
layer 1
