Physical layer
In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer. The implementation of this layer is often termed PHY.
The physical layer consists of the basic networking hardware transmission technologies of a network. It is a fundamental layer underlying the logical data structures of the higher level functions in a network. Due to the plethora of available hardware technologies with widely varying characteristics, this is perhaps the most complex layer in the OSI architecture.
The physical layer defines the means of transmitting raw bits rather than logical data packets over a physical link connecting network nodes. The bit stream may be grouped into code words or symbols and converted to a physical signal that is transmitted over a hardware transmission medium. The physical layer provides an electrical, mechanical, and procedural interface to the transmission medium. The shapes and properties of the electrical connectors, the frequencies to broadcast on, the modulation scheme to use and similar low-level parameters, are specified here.

Look @ Me
by: TeslaWell i'd never break your heart, now tell me would you break mine
Re-wind and clean the slate, wipe away the hard times
Well i never did forsake you, and i never would
I got away from the common ground, just because i could
There was a shadow, following me around
Somehow i lost my way, that was then, take a look at me now
Chorus
For everything in life, there is a reason
Sometimes the reason i do, make it not so good
Verse 2
Seems like all that time away took me one step closer to my suicide
Spun around like i jus got played, all caught with the users and the crucified
A shining example of what you never wana be
The fame of teachers drowning in a wishing well
With no apology
Me and my shadow, no-body else around, somehow i lost my way, that was then take a look at me now
Chorus
Short Verse
Feels like the time is right for getting back to even
You are the reason i do, aint that enough for you!

Aint that enough for you
You are the reason i do
