Category 5 cable, commonly referred to as cat 5, is a twisted pair cable for carrying signals. This type of cable is used in structured cabling for computer networks such as Ethernet. The cable standard provides performance of up to 100 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet). Cat 5 is also used to carry other signals such as telephony and video.
This cable is commonly connected using punch-down blocks and modular connectors. Most category 5 cables are unshielded, relying on the balanced line twisted pair design and differential signaling for noise rejection.
Category 5 was superseded by the category 5e (enhanced) specification, and later category 6 cable.
The specification for category 5 cable was defined in ANSI/TIA/EIA-568-A, with clarification in TSB-95. These documents specify performance characteristics and test requirements for frequencies up to 100 MHz. Cable types, connector types and cabling topologies are defined by TIA/EIA-568-B. Nearly always, 8P8C modular connectors (often referred to as RJ45 connectors) are used for connecting category 5 cable. The cable is terminated in either the T568A scheme or the T568B scheme. The two schemes work equally well and may be mixed in an installation so long as the same scheme is used on both ends of each cable.
I can't know what you feel inside.
But your face can't hide your foolish pride.
Keep in mind all you left behind
Was in chains that bind: is that a sign?
I can't read what you keep inside your mind,
Protecting what I find within your walls.
Things I feel that I know just can't be real.
Trick and try to steal my life away.
Cold deception goes both ways.
Watch yourself or you'll get bathed.
In the darkness that is light.
As your spirit dies tonight.
I'll tell you something- I know I must be strong.
For your giving me something- That I know is wrong.
I can't know what you feel inside,
But your face can't hide your foolish pride.
Keep in mind all you left behind
Was in chains that bind: is that a sign?
Your intentions become clear.
All deceptions disappear.
The inception of your plan.
Marks the end of modern man.
I'll tell you something- I know I must be strong.
