• 128-bit encryption for security

Patch Panel >>>

Patch Panel


A patch panel or patch bay is a panel, typically rackmounted, that houses cable connections. One typically shorter patch cable will plug into the front side, whereas the back holds the connection of a much longer and more permanent cable. The assembly of hardware is arranged so that a number of circuits, usually of the same or similar type, appear on jacks for monitoring, interconnecting, and testing circuits in a convenient, flexible manner.

Patch panels offer the convenience of allowing technicians to quickly change the path of select signals, without the expense of dedicated switching equipment. This was first used by early telephone exchanges, where the telephone switchboard (a massive array of patch panels) and a large room full of telephone operators running it was ubiquitous.

Information outlet >>>

In a telephone wiring system in a building, a connection device designed for a fixed location (usually on a wall) in which telephone wiring terminates; the outlet contains a female jack to receive a male plug that is inserted into it. Such outlets are used to connect a telephone, FAX, telephone answering machine, etc., to a telephone line.

Difference between Router and Switch >>>

ROUTER
A router is a device or, in some cases, software in a computer,
that determines the next network point to which a packet
should be forwarded toward its destination.
The router is connected to at least two networks and
decides which way to send each information packet based
on its current understanding of the state of the
networks it is connected to.
SWITCH
While the network switches are capable of inspecting
data packets as they are received, determining the
source and destination device of each packet,
and forwarding them appropriately.

Conclusion..

For me, router and switch is related to each other
because routers allow several switches to be
connected to them, as a means to expand
the local network to accommodate
more Ethernet devices.
