A class of methods for sharing a datatransmission medium in which hosts transmit as soon as theyhave data to send and then check to see whether theirtransmission has suffered a collision with another host's.If a collision is detected then the data must be resent. Theresending algorithm should try to minimise the chance that twohosts's data will repeatedly collide. For example, theCSMA/CD protocol used on Ethernet specifies that theyshould then wait for a random time before re-transmitting.See also backoff.This contrasts with slotted protocols and token passing.

Platidiam
- An inorganic water-soluble platinum complex. After undergoing hydrolysis, it reacts DNA produce both intra interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity cisplatin correlates with cellular arrest in G2 phase cell cycle.
