RJ45 may refer to:
A Registered Jack (RJ) is a standardized telecommunication network interface for connecting voice and data equipment to a service provided by a local exchange carrier or long distance carrier. Registration interfaces were first defined in the Universal Service Ordering Code (USOC) system of the Bell System in the United States for complying with the registration program for customer-supplied telephone equipment mandated by the Federal Communications Commission (FCC) in the 1970s. They were subsequently codified in the Code of Federal Regulations Part 68.
The specification includes physical construction, wiring, and signal semantics. Accordingly, registered jacks are primarily named by the letters RJ, followed by two digits that express the type. Additionally, letter suffixes indicate minor variations. For example, RJ11, RJ14, and RJ25 are the most commonly used interfaces for telephone connections for one-, two-, and three-line service, respectively. Although these standards are legal definitions in the United States, some interfaces are used world-wide. Specifically, for example, the IEEE 802 standards project has adopted RJ-type interfaces for ISDN (RJ48) and computer networking specifications (RJ45), such as Ethernet.
A modular connector is an electrical connector that was originally designed for use in telephone wiring, but has since been used for many other purposes. Many applications that originally used a bulkier, more expensive connector have converted to modular connectors. Probably the most well known applications of modular connectors are for telephone jacks and for Ethernet jacks, both of which are nearly always modular connectors.
Modular connectors were originally used in the Registration Interface system, mandated by the Federal Communications Commission (FCC) in 1976 in which they became known as registered jacks. The registered jack specifications define the wiring patterns of the jacks, not the physical dimensions or geometry of the connectors of either gender. Instead, these latter aspects are covered by ISO standard 8877, first used in ISDN systems. TIA/EIA-568 is a standard for data circuits wired on modular connectors.
Other systems exist for assigning signals to modular connectors; physical interchangeability of plugs and jacks does not ensure interoperation, nor protection from electrical damage to circuits. For example, modular cables and connectors have been used to supply low-voltage AC or DC power and no clear standard exists for this application.
She was sixteen, looking at a sick scene
Just broke up with her boyfriend it's killin her self esteem
See the slt wrist bleed feelin like she should scream
Shes hurting herself just to see if it's a dream
She can't wake up, just look at her make up
It's runnin down her face from the tears in her eyes
To leave their path when they dry and they solidify
Cause when an angel crys her tears are crystallized
Her ex boyfriend ain't a man he was fake
Now shes staring out in space, cause her period was late
Got the world on her shoulders she feel they about to break
She can feel it in her brain - and down to her cold spine
It's crazy how one minute can change your whole life
Now she gonna be a single mother not a loving wife
He told her they would be together forever till death
Now the only positive thing in her life was the pregnancy test
It rains and it pours every time an angel crys
So I walk through the storm cause the tears are crystallized
A baby is born everytime someone dies
So when it comes to this world that's why it crys
It rains and it pours every time an angel crys
I walk through the storm cause the tears are crystallized
A baby is born everytime someone dies
So when it comes in this world that why it's crys
He was just a little boy but he's acting like a man
He wouldn't listen to his teachers cause he thought he had plan
From the pills, to the grams, to the booze, to the rhymes
It was all he needed cause it's was all he seen in his life
His girl was too young to even understand the drugs
She just looked the otherway and let him get fucked up
Through the kisses, and the hugs, the only one who showed him love
He was too dumb to realize cause he wanted to be thug
He wanted to be tough, he wanted to be a soldier
Wanted to stand on the top of the world when it's all was over
Never was he sober, livin the american dream
Until he realized what it's like to be a real emcee
He broke up with his girl don't even remeber the reason
Got a head full of demons, so can I tell you a secret
That little boy was me but when I look at my dad
I know I wanna be different but I walk the same path
It rains and it pours every time an angel crys
So I walk through the storm cause the tears are crystallized
A baby is born everytime someone dies
So when it comes in this world that's why it crys
It rains and it pours every time an angel crys
So I walk through the storm cause the tears are crystallized
A baby is born everytime someone dies
So when it comes in this world that why it's crys
You were listening to music and having a good day
Till you stumbled on my page and heard a song by rage
Since my music is true it can ruin ya mood
It points out the flaws when you do what you do
My music is depressive, I could use it as weapon
Or you could just listen and use it to fix your own perspective
I put my mistakes in a track and write a verse from it
Cause If I tell you my mistakes then you can learn from it
Got this urge in my stomach cause I kinda feel fake
I got all this music telling you I'm great
But I suck at my life, I was made from a mistake
So take what you want from me, then take me away
I don't want no sympathy I don't want you to cry
Your all so beautiful - an angel in disguise
Even though I'm filled with hate I keep a smile on my face
Cause my frown could bring you down - can you relate?
It rains and it pours every time an angel crys
So I walk through the storm cause the tears are crystallized
A baby is born everytime someone dies
So when it comes in this world that's why it crys
It rains and it pours every time an angel crys
So I walk through the storm cause the tears are crystallized
A baby is born everytime someone dies
So when it comes in this world that why it's crys
It rains and it pours every time an angel crys
So I walk through the storm cause the tears are crystallized
A baby is born everytime someone dies
So when it comes in this world that's why it crys
It rains and it pours every time an angel crys
So I walk through the storm cause the tears are crystallized
A baby is born everytime someone dies
