CDPD is a secure, proven, and reliable protocol that has been used for several years by law enforcement, public safety, and mobile professionals to securely access critical, private information. CDPD has several features to enhance the security of the mobile end user's data and these are discussed below.
OPERATION OF CDPD
A brief overview of the operation of the CDPD network is as follows:
A wireless modem (or Mobile End System-M-ES) communicates by radio with the Mobile Data Base Station (MDBS). The MDBS transfers this data by landline and microwave to the Mobile Data Intermediate Systems (MD-IS), which processes and sends the information, by Intermediate System gateways (routers), to the appropriate destination.Over the years semiconductor devices have set a new trend in the field of electronics and created waves in the existing technology of memory storage. Flash memorywhich has been in use for long now , is now being replaced by new advents in technology of memory such as Ferro Electric Memory, Magneto resistive Type Memory and Ovonic Unified Memory. This paper contrasts the working of flash kind of memory used in Dynamic - RAMS with that of the other types mentioned above . In brief , advantages over the flash kind of memory are evaluated and justified.
In a world where "nanoseconds " matter a lot , 'the new Technology ' awaits recognition and exposure
