In computer networking, unicast transmission is the sending of messages to a single network destination identified by a unique address.
The term unicast is contrasted with the term broadcast which means transmitting the same data to all possible destinations. Another multi-destination distribution method, multicasting, sends data only to interested destinations by using special address assignments.
If an IP Unicast packet passes through a switch that does not know the location of the associated MAC Address, the packet will be broadcast to all ports on the switch. This failure of Unicast to 'cast to a single device' is called a Unicast flood.
Unicast messaging is used for all network processes in which a private or unique resource is requested.
Certain network applications which are mass-distributed are too costly to be conducted with unicast transmission since each network connection consumes computing resources on the sending host and requires its own separate network bandwidth for transmission. Such applications include streaming media of many forms. Internet radio stations using unicast connections may have high bandwidth costs.
Who is this girl?
She's driving in the rain,
And she's listening to the songs,
That she knows will bring her pain.
Reflecting on her life,
Contemplating every move,
She apologizes for all her wrongs,
Even though she's got nothing to prove.
She isn't allowed to be faltered,
She puts others before her,
She has to perfect even though she's the weakest.
She said,
"Do you think I could speak?
Do you think I could breathe?
Lay your head on my chest,
Can you hear my heart beating?"
If you'd only look closer,
You'll see that there's someone she's trying to hide,
If you'd only look sooner,
You'll see that she's suffering inside.
She's trapped between the person she is,
And the person she's supposed to be,
She fakes her smiles and she fakes them so she believes them,
She does what people tell her to,
'Cause she can't make her decisions.
She said,
"Do you think I could speak?
Do you think I could breathe?
Lay your head on my chest,
Can you hear my heart beating?"
If you'd only look closer,
You'll see that there's someone she's trying to hide,
If you'd only look sooner,
You'll see that she's suffering inside.
She's looking forward to holidays,
Because they're the only days that still have meaning.
She said,
"Someone turn off the music,
Can you hear me screaming?"
She said,
"Do you think I could speak?
Do you think I could breathe?
Lay your head on my chest,
Can you hear my heart beating?"
If you'd only look closer,
You'll see that there's someone she's trying to hide,
If you'd only look sooner,
