- Klak, on 02/22/2009, -4/+152wow. a computer text book.
- dipdog21, on 02/22/2009, -9/+67And why would this reach the front page...
- defenswens26, on 02/22/2009, -3/+57I love the quote at the bottom:
"The Bank of America in California has a network of 50 microcomputers" WOAH!!! - r0b1, on 02/22/2009, -2/+42Say, I got some old books on computer architecture from college - maybe I could take a picture of one of the pages, post it on Digg, and make front page!
- GOJOE, on 02/22/2009, -1/+37Oh man... Token ring... Those things were a pain in the ass! Pretty much the computers were hooked up in series (with the last one hooked up to the first one), and if your computer wanted to talk to the network, it had to be holding onto the token. Kinda like an AA meeting where the only person that can talk is the person with the magic stick. The idea was to prevent collisions (so 2 computers wouldn't try to talk over each other). But really... It was just hell.
- Janv1er, on 02/22/2009, -2/+32And their 50 minicomputers
- realunderdog, on 02/22/2009, -2/+31The good old days DOS and Trash80's with 300 baud modems for fido net
- adverpart, on 02/22/2009, -0/+29What's funny is the guy who scanned it put it under a Creative Commons license demanding attribution to him, and that people re-distribute it under his license. It's not his book, and it's still under copyright. You can't just arbitrarily put a different license on it just because you scanned it.
- xdarkfluxx, on 02/22/2009, -3/+28Yea honestly how does a page from a computer textbook get on the front page of digg. Very Very slow news day I guess.
- Gr00ver, on 02/22/2009, -3/+28Back in the day when computers were connected via lightning bolts.
- Kruse, on 02/22/2009, -1/+23So you connect the TVs to the dishwashers?
- oboshoe, on 02/22/2009, -5/+26Token Ring.
KILL IT! Kill it with fire!
Do not again speak of its name, lest it be born again and torment us all! - oboshoe, on 02/22/2009, -1/+20
The topology of the Internet looks more like a bag of Christmas tree lights that has been shaken up and thrown on the floor. - conversekid, on 02/22/2009, -8/+26Twas cool until I saw "Bank of America" :(
- erkokite, on 02/22/2009, -2/+20Actually it's not a star or a mesh. It's a series of tubes.
- joshuaok, on 02/22/2009, -1/+17So far, only one commenter seems to understand how networks really work. Interesting...
- conna, on 02/22/2009, -0/+14At least it is a tech article.
- inactive, on 02/22/2009, -0/+13Make sure it involves some sort of ***** cat picture, that will surely propel it to the front
- oboshoe, on 02/22/2009, -2/+15dugg for comparison to AA meeting.
- KotZer, on 02/22/2009, -1/+11In 1988 laundry machines were used as servers
- R031E5, on 02/22/2009, -1/+11Because it was submitted by a poweruser, that's why.
- offrdbandit, on 02/22/2009, -1/+11The vast ignorance being displayed here is troubling.
Why is everyone assuming the ring topology is a token ring (as if you couldn't build and operate an Ethernet ring, for example)??? The images are illustrations of the specific network concepts in a computer network context.
The graphics are interesting because of their "retro" styling and color choices (if you were to show those terminal graphics to a kid today, he/she would probably not even recognize it as a computer), but the ring network isn't "retro" in any way. - cdbatty, on 02/22/2009, -0/+10yeah... the technology was shocking back then wasn't it?
- HappyScrappy, on 02/22/2009, -1/+11Unless you designed network controllers, why do you give a crap how the network arbitration works?
IBM's MAUs made it so that you didn't even have to know it was a ring when cabling it. - MrTeQ, on 02/22/2009, -0/+9Pretty sure Visio still has these stencils available.
- soogy, on 02/22/2009, -1/+10You could use a lesson in manners. You don't have to insult the guy to correct him.
- spinladen, on 02/22/2009, -2/+11Would taking a picture of an AOL 2.0 Free Trial install cd wow the young ones as much? I knew them 20 free hours would be front page Digg material at some point...
- joshuaok, on 02/22/2009, -1/+10No, but you damn sure knew it was a ring when one of the nodes went down.
- Ryan_KW, on 02/22/2009, -0/+8That Compu-Serve disk probably has Mosaic on it. It's an upgrade if you're using IE6.
- cdbatty, on 02/22/2009, -1/+9Ahhh....so that's what the 'M' looks like in RTFM
- WELLDOITLIVE, on 02/22/2009, -1/+9One ring...
- franklymister, on 02/22/2009, -0/+81988 is like, yesterday.
Although, considering that the average age of Digg users seems to have begun hovering somewhere around fifteen, I suppose it must seem like ye olde tymes whar be dragons. - offrdbandit, on 02/22/2009, -2/+8Computer Science is mathematics.
Mathematics does not change. - raydeen, on 02/22/2009, -0/+6Rings are good at fault checking. If the packet doesn't get a confirmation from a node, it raises an alarm pointing out where the fault is occurring. It was good for small setups but didn't scale well, so the layout for large setups would be lots of small rings attached to hubs or switches in a star formation.
- justjoehere, on 02/22/2009, -0/+6*groan*
- speshul, on 02/22/2009, -1/+7tolkien's ring gives even more trouble.
- roxgod666, on 02/22/2009, -2/+8I tried my hardest to try to find this somewhat decently cool on a moderate level. No luck.
- Qbryzan, on 02/22/2009, -0/+6[Pedantic nitpick of previous comment, as an attempt to show off and assert technical dominance]
- andy3109, on 02/22/2009, -0/+5You would be surprised that token ring variations have been coming back strong with ad-hoc related networks (manet, vanet, etc.)
- JonyBigHead, on 02/22/2009, -3/+8I like how computers communicate via bolts of lightning in 1988
- Azdak, on 02/22/2009, -1/+6Coasters, dude. Coasters.
- oboshoe, on 02/22/2009, -1/+6token ring as a layer 1/layer 2 construct was and is full of fail.
The idea at the application layer(ish) layer appears to be much more viable. - superterrorizer, on 02/22/2009, -1/+5Probably not, but I have an old Compu-serve disk that I found from waaaaaaay back in the early/mid 80's that my parents had.
- poprocksandsoda, on 02/22/2009, -9/+13The key network topology being used in that 80's diagram is the very same topology used by the Internet: Star Networking. The Star Network was overkill for small implementations but it's great for providing the kind of redundancy provided by the Internet. The token ring at the bottom was an absolute nightmare to implement, but it's very likely that future high performance networks will move more towards this topology as it has tremendous benefits around security and traffic prioritization.
- WDUK, on 02/22/2009, -2/+6The network topologies mentioned in that diagram still apply today, with a couple more (like a Bus network, or a Mesh network).
I can't really see the coolness in it though, I had to study from a similar diagram a few weeks ago, and all I could think about was exams! - booyahbitch, on 02/22/2009, -0/+4You know...there is gigabit token ring!! :o)
- thethirdmoose, on 02/22/2009, -0/+4Do you even know what computer science *is*?
- cornernoize, on 02/22/2009, -1/+5Computers: Connected by lightning
- HeresyAct, on 02/22/2009, -0/+4Serial connections dude...
- inactive, on 02/22/2009, -1/+5"The good old days"
Well, I would agree with "the", "old", and "days" but definitely not the "good." -
