Category 5 was developed for Fast Ethernet.
On-site support is provided via Internet for the HomeConnect Home Network Ethernet Hub.
They can support multiple higher-layer protocols, and Ethernet 802.3 frames cannot.

Yes.
because they can support multiple higher-layer protocols
If you don't have enough ethernet sockets in a router, you can plug a switch or a hub into the socket. The hub or switch will supply support for additional ethernet cables.
Anyone who wants to expand a wireless home network can do so with a bridge. Most wireless routers have four Ethernet ports, so this limits the amount of devices which could be connected through cables. A network bridge is a networking accessory which has Ethernet ports for compatible devices. The bridge can be connected to an existing router through Ethernet cables or wireless methods. The bottom line is that a network bridge ultimately links additional Ethernet ready devices to a router that can only physically support four Ethernet connections. A network bridge is similar to a USB hub in that it extends the number of possible connections.
To sponsor a category is to provide funds for support on a project, an activity, or to a person. A non sponsored category is one that requires no financial support or that could be independently funded.

Yes. A Cat-5 line can be used to supply power to certain Ethernet Switches that support POE, or Power Over Ethernet.
10BASE-T and all the generations of Ethernet Technologies released after 10BASE-T support full duplex. Full duplex mode allows two nodes on a network to communicate with each other simultaneously.
There are a few places online where one can get support for a Realtek RTL8139 family PCI fast Ethernet NIC. Tech Support would be one such place. One could also check with local computer shops to see if they are able to offer the support needed.
