A measure of airflow, and you can use it to compare the efficiency of fans designed to cool computers or computer components. Higher CFM rates are better. ISP Glossary:
CFM - By John WalkoCommsDesign.comLONDON - The GSM Association is playing down concerns raised by ateam of Israeli scientists about the security of GSM mobile calls.The researchers, from the Technion Institute of Technology in Haifa,revealed they had discovered a basic flaw in the encryption system ofthe GSM (Global System for Mobile) specification, allowing them tocrack its encoding system.The GSM Association, which represents vendors who sell the world'slargest mobile system, confirmed the security hole but said it wouldbe expensive and complicated to exploit.Eli Biham, a professor at the Technion Institute, said he was shockedwhen doctoral student Elad Barkan told him he had found a fundamentalerror in the GSM code, according to a Reuters report on Wednesday(Sept. 3). The results of the research were presented at a recentinternational conference on cryptology.We can listen in to a call while it is still at the ringing stage,and within a fraction of a second know everything about the user,"Biham told the news agency. "Then we can listen in to the call.""Using a special device it's possible to steal calls and impersonatecallers in the middle of a call as it's happening," he added. GSMcode writers made a mistake in giving high priority to call quality,correcting for noise and interference and only then encrypting, Bihamsaid.http://www.commsdesign.com/printableArticle?doc_id=OEG20030903S0013
