RE: CSMA/CD : full duplex
To be pedantic, a collision is an event which occurs over the wires/fibre. If congestion happens internally in a switch/router it may be a problem but it is not in network speak a collision. > -- > From: woody[SMTP:[EMAIL PROTECTED]] > Reply To: woody > Sent: 11 May 2000 10:22 > To: [EMAIL PROTECTED] > Subject: Re: CSMA/CD : full duplex > > Further to my original post... > > It is possible to get collisions on a Full Duplex segment.

RE: Fibre Optic - 100FX
1/2 duplex has a potential for collisions hence the distance is set by the requirement for 512 bit intervals between transmissions?? full duplex the limit is set by the physical characteristics of the fiber?? well thats my guess im > -- > From: Tan Choh Koon[SMTP:[EMAIL PROTECTED]] > Reply To: Tan Choh Koon > Sent: 10 May 2000 16:31 > To: CiscoGroupStudy > Subject: Fibre Optic - 100FX > > Hi all, > > Do anyone know the theory why 100Mbps Hub with Multimode fiber link, the > distance is 412 m for Half Duplex and 2000 meter for Full Duplex mode ?? > > > ___ > UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html > FAQ, list archives, and subscription info: http://www.groupstudy.com > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] > ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
