About the TCP black filled icon
A square ethernet socket sits inside a thin circle: the front face shows a row of gold-pin contact slots across the top, the stepped keyway shaped for an RJ45 clip below, and two small screw squares at the base. It stands for wired networking, LAN links and TCP/IP connectivity. Use it in router and switch spec sheets, network configuration screens, data center diagrams, ISP plan comparisons, and IT hardware catalogs.
The port fills the circle squarely, so the stepped inner cut stays the recognizable feature even in a compact toolbar. It pairs with wifi, router, server and cable icons from the same networking set. Draw it at 32 px or larger so the eight pin slots do not blur into one bar.
This is the solid black filled version of the tcp icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
