As with desktop operating systems, the Windows CE basic system features programs and functions to
facilitate working with the system. To mention here just a few:
•
Complete IP-based network stack in addition to network drivers used for the network interfaces
configured for the device
•
Browser components for http access
•
Remote desktop client for remote access to a terminal server
•
ftp client and server functionality for data transfer
•
ActiveSync
•
Inherent power management infrastructure
•
Update mechanisms for various applications
•
Remote management and administration access via the vnc protocol
•
Stacks for other communication interfaces: Bluetooth, WLAN, Ethernet, IrDA etc.
When installing application programs and other device drivers, various aspects have to be considered due to
the OS monolithic kernel architecture. These relevant aspects will be touched on briefly below.
1.2.2 Permanent storage of folders and files
.
ATTENTION
On ACD Windows CE devices from the SE series, the entire root file system (with the
exception of the \temp folder) is flash-based, i.e. persistent. Depending on its particular
configuration, the device can also contain other persistent storage modules (for example on an
internal SD card)
The special \temp folder is stored in a RAM-based file system. New files can be created in this
folder however they will be lost when the device is switched off. This folder is reserved for
temporary files only, for example installation files.
1.2.3 Saving the registry
Based on the system registry with desktop Windows systems, Windows CE also features a Registry. It saves
common Windows settings such as network parameters, language and country settings, touch calibration
and even the width of the scroll bar. In contrast to desktop Windows systems, these settings are retrieved
from a reserved memory when the OS is booted and then stored on the device's RAM. They will be lost
when the device is switched off.
To store these changes permanently, they must be explicitly saved. This can be done using the
Save Registry or Sys-Tools programs. These programs are launched at Start / Programs / SysTools and
each persist the registry in as a whole.
