mobile is one type of handheld computer:
An Enterprise digital assistant (EDA) is a handheld computer, born of the Personal digital assistant popularity which was adapted for extensive more robust usage within the Small andmedium enterprisesSME (Small to Medium Enterprise) and Enterprise business Application softwareApplications as a Data Capture mobile device.Over the years, these business applicationshave grown from simple batched data collectionusing Barcode readers to include extensive usage of other expanding business technologies within the areas of WLANs (Wireless Local Area Networks),GPRS Edge Communications, Biometrics,Magnetic Stripe, Smart Card and RFID data capture technologies.EDAs are also known as Data Capture Mobile Devices or Batch Terminals or Portables.EDAs have many uses in many types of business: Warehouse management, Inventory control andField Services to mentions a few.EDAs, are to the business sector, what the Personal digital assistant where to the domesticsector,which allows business applications to combine a portable device with their data collection requirements.As is the case with Personal digital assistantPDAs, EDAs may include a Touch Screen, IrDA,Bluetooth, a Memory card slot, however EDAs may also include one or more data capture devices.EDAs, are available on a variety of different Operating systemOS Platforms i.e. WindowsCE, Windows Mobile, Windows PocketPC, Windows XP Tablet Edition, Linux (Various), Palm OSPalm, DOS and some proprietary Operating systemOS Platforms.As the gray area between a Personal digital assistantPDA, Smartphone and EDA can be blurredwhen comparing the wide array of common features and functions, where EDAs attempt to define a difference is within business mobility applications which normally bring a pre-define requirementfor long term constant daily operation (Normally allowing a minimum of 8 hours), and a higher than normal Ingress ProtectionIP rating (impact rating / Drop Test) of no less than an IP54rating, when compared to Personal digital assistantPDAs, combined with a minimum of a leastone Data Collection function i.e. a Barcode or RFID Reader etc.An EDA is designed to withstand all-day everyday use in more harsh or hazardous environments,these rugged compact devices can deliver wireless Wide area networkWAN/LAN/Personal AreaNetworkPAN voice and data communications, including VOIP functionality.EDAs are available in a number of form factors, for example Handheld or Wearable and can be further extended to include figure [[barcode scanners, RFID panel Antennas, Swipe card readers,External Battery Packs and Integrated Mobile Computer printerPrinter carry cases.Where PDAs are intended as single person devices for personal applications and usage, EDAsare very often intended as multi-person devices for business applications and usage.PDAs can be expanded to add-on data capture functionality, whereas EDAs very often are designedwithout the need for additions and can include a combination of built in data capture functionality.Barcode_scanner or RFID Reader, 802.11b/g Wifi, GSM, GPRS and VOIP are the most common standards of functionality within EDA mobile devices.Retrieved from different sites.
