The -> question is ... are the two terminators in serial or parallel -> so that either a 100 or 25ohm terminator could be installed -> directly onto the thinnet connector? You're right on both solutions. I recently made a couple of terminators with two 100 ohm resistors in parallel. Go from the center conductor to the resistors, then to the shield/ground wire. We used solder and heat shrinked the two resistors together and added some outer heat shrink to make them look pretty. They're both still going strong.

Are you running "client-server" ? If so, then a dedicated server is the obvious solution. A dedicated server is also easier to administer in a "secure" network. If you are after resource sharing, distributed processing, and/or mediocre to nil security, then Peer-peer is the way to go. You can get high security but the effort is huge. HW> 3) What's the function of a router ? Does it act like a UTP hub whilst HW> routing the data-packets only to the machine that there adressed to, HW> thereby bringing down the load on the net as a hole ? A router is a glorified bridge. After that statement, what is a router ? It's a device that routes packets according to a pre-decided routing table. With a router, you can have two of the suckers connecting two segments/networks together. The routers will decide which one is "active and forwarding" and which one is "blocking". If the one that is forwarding should fail, the second router will assume the function of the first. That's assuming it hasn't taken down the segment(s) entirely. Bear in mind that this is a very simplified illustration as in real-life, there may be a very complicated network (such as the Internet) and there are routers that are =really= smart and route dynamically as required. HW> 4) In very broad terms, what are the advantages\drawbacks of Novell Netware HW> versions 2.x, 3.x and 4.x ? This I cannot say with authority so I'll leave it to someone else. HW> 5) As i understand, W95 can be run on top of Netware, can OS\2 also run on HW> it ? OS/2 Warp Server has it's own Netware drivers as far as I am aware. I haven't had to use that combination yet.

Is it the central server concept that makes the difference HW> ? The Netware server is a full 32 bit operating system with a 32bit file system. Along with that, the inbuilt multi-tasking disk access is awesome. It's a =real= performer. Note however that OS/2 and NT both have a 32bit file system and are real performers too, OS/2 especially. Netware will soon have to pull some tricks to make it's server faster - or die. It's market share is starting to slide, and I can only see the trend accelerating - which would be a real shame. I prefer alternatives and competition. It helps to keep the bastards honest and receptive. Not that that facit has never infected MS.

I haven't gone into specifics, deliberately, so as not to confuse you more than necessary.

Yes, but I would prefer Windows 95 over the Mac System anyday :-). The cybercafe here downtown has eight Win95 computers (loaded) which are hooked up together via Ethernet to play games, utilize Network Neighbourhood, etc. The network doesn't have a fileserver, and seems to operate fine without one; each computer has it's own hard drive with Win95/Internet, etc. What are the advantages of Unix over DOS/Windows?

Some brands of carrier channel bays steal a bit from one channel, or from either channels 6, 12, 18, and 24, or from 12 and 24, for additional sync. Other brands and models do not steal additional bits. Any restriction from 64 to 56 kbps subchannelization is either a matter of hitting one of those minority of restricted subchannels, or a telco choke so that all subchannel usage will be identical within their network. There is nothing inherent in either T-1 or DS-1 that requires subchannelized usage. That's simply a common internal telco utilization and hardware buildout. T-2/DS-2, rarely used, is 4x, not 2x, T-1/DS-1 capacity, BTW. Terry --- Maximus 2.01wb * Origin: Terry's Tavern! (1:141/1275)
