wired network setup

chapter 14

hubs, switches, and routers

A wired, or Ethernet, network is connected using a CAT-5 (Ethernet) cable. You run one end of a cable to each computer with a NIC, and connect each cable to a hub, switch, or router at the other end.

hubs

A hub takes its signal from each computer and sends it to all of the other computers connected to the hub. Hubs, however, are passive—other devices on the network plug into the hub in order to communicate with one another. A hub does not manage the network.

switches

A switch, on the other hand, makes it possible for several users to send information over a network at the same time without slowing each other down. Switches allow different nodes (a network connection point, typically a computer) of a network to communicate directly with one another.

Most networks, however, do not consist entirely of switches due to the cost of replacing all of the hubs with switches. Instead, a combination of switches and hubs are used to create an efficient yet cost-effective network.

routers

Routers allow distinct networks to communicate with each other. A router can link a network to the Internet; link two networks and connect both to the Internet; and help secure networks through the use of firewalls and assigning dynamic addresses. A router can also act as a gateway, while a hub or switch cannot.

A gateway can either be a router or a Windows computer running Internet Connection Sharing (ICS). For more information about ICS, see the documentation that came with your Windows computer.

Note: For specific information about the hardware on your network, see the manufacturers’ printed or online documentation.

cables

Use an unshielded CAT-5 Ethernet cable to connect your HP PSC to an Ethernet network. The CAT-5 Ethernet cable is also known as a straight-through cable. Your computers, broadband modem, and HP PSC must be attached to a router or hub with a straight-through cable. The straight-through cable uses an RJ-45 plug.

RJ-45 plug

Although standard Ethernet cables look similar to standard telephone cables, they are not interchangeable. Connectors for Ethernet cables are wider and thicker on the end, and Ethernet cables have eight wires running to the connector at the end instead of four.
