what type of system will interconnect 20 workstations in one room and twenty in the other to a central server?

first u have to build a LAN with 20 systems using a switch/hub then conect both the rooms network with the centralized server.

Use a hub to connect the four PC's\nUse cat5 cable to a NIC card in each pC\nSelect workgroup group in computer properties,  give it a name (same for all PC's)\nselect tcp/ip as transport  use a ip range as in 10.10.10.1 /2/3/4\none in each pc. \nSubnet mask can be put in use 255.255.255.240 or leave blank\nin a closed network this size the PC's will find each other anyway.

yes! \n\nnetwork server and/or a mainframe computer. Both are considered "computers" basically.

i'd go for HP or IBM servers

If you only want to link the computers to each other, install NIC's in each machine, and connect them using a crossover ethernet cable.\n\nIf you want to network the computers and share an internet connection, the method will be determined by whether you have dial-up or a high speed (DSL or cable) connection.  You don't give enough information to point you in the right direction.

A proper switch is nothing more then a switching hub, or intelligent hub.  It acts as a logical bridge, but allows a physical and logical start topology.\n\nAs previously indicated a switching hub, can learn where devices are located and send packets accordingly.\n\nYes, you can connect switches and hubs together, although it would benefit you to use switching hubs, preferably from the same vendor.  Some intelligent hubs can communicate and manage resources better within a segment.\n\nFor your project, you may need a switching hub on each floor but not necessarily.  If the distance is not too great for the specific ethernet you select, a "collapsed" network (single star) configuration is much more cost effective.  With the collapsed design you will have to have more and longer "home runs" or cable runs to the ports from the switch, but each port will get full bandwidth.\n\nIf you place a switch on each floor the maximum speed you can achieve is whatever the shared bandwidth is available between the switches, between each floor.  So if you connect two floors with a switch on each floor, and the servers are on one floor and workstations on the other, using a 1Gbps connection between switches - your workstations all share the 1Gbps connection to the server, no matter they have 100Mbps to the switch on their floor - the workstation switch cannot talk faster then 10 X 100Mbps or 1Gbps to the other switch where the servers are.\n\nMost large switches that can manage hundreds of ports have 10, 20 or even 100Gbps communications on the backplane (within the switch itself), providing full 100Mbps communication from each workstation to each server.

Concentrator - A device that provides a central connection point for cables from workstations, servers, and peripherals. Most concentrators contain the ability to amplify the electrical signal they receive.\n\nWorkstation - A computer connected to a network at which users interact with software stored on the network.\n\nA little more detail:\n\nhttp://en.wikipedia.org/wiki/Concentrator\n\nhttp://members.tripod.com/barhoush_2/hardware.htm\n\nhttp://fcit.usf.edu/network/chap5/chap5.htm\n\nHope that helps!

Try going to http://www.digg.com  or http://www.tomshardware.com for latest info.  The latest thing I heard of is the Desktop Supercomputer, which is basically 8 blade servers mounted in a chassis together using multi-core Linux or Windows - 16 fast processors at once, you can't go wrong!

I'm not sure but my answer is 3 Metro Ethernet

You are going to have to be much more specific in your question.  Are you referring to a LAN operating system, just connecting a few PC's together, or a multi-user application software (and in this case, what application?)

Supercomputer? That term is a bit outdated.\nFollow this link and you should be able to find everything you need.

You can use what is called a KVM switch.  It allows you to use one keyboard, one mouse and one monitor with 2 PCs.\n\niogear makes some great products.

Each PC requires a NIC (network connection), then you'll need either \na single crossover cable \nOR \ntwo normal network cables and a switch.

A network hub with both types of connection will do it. Probably cant get an actual hub, since most such devices are switches these days

1. Buy a 16 port switch (you could buy a 12 port switch but you should always have a few spare ports...you never know when you need them). Connect the computers to the switch using straight UTP cables. Assign IP addresses from the same network class to the computers. \n2. You could build a wireless network, but it's more expensive buying wireless cards than a switch and the transfer rate is lower
