Network ID

Here used to mean that you should configure the Windows user settings, such as the user

name, password, and domain name. Microsoft’s definition includes some wireless network

IDs as equivalent to SSIDs.

non-persistent

state

A non-persistent state affects only the next keypress. FN state is a non-persistent state.

object store

The persistent storage that Windows CE makes available to applications. For example,

Windows CE reserves part of its available RAM for the operating system and uses the rest

for the object store. This data can be stored in files, registry entries, or Windows CE data-

bases.

PING

Protocol that sends a message to another computer and waits for acknowledgment, often

used to check if another computer on a network is reachable.

portable data

assistant (PDA)

A handheld Windows-based (Pocket-PC or Windows CE) computer that can be synchro-

nized with a host PC to share files and data. Sometimes contains an infrared device to

beam information to another unit.

portable data

terminal (PDT)

An industrial strength handheld computer with a keypad, navigation keys, and a bar code

scanner used in inventory, retail, and warehouse activities to collect data and upload it to a

host PC.

persistent state

A state which is maintained after releasing a key. Alpha mode is a persistent mode. Also

called a “sticky” state. A persistent state must be turned off by pressing the key again.

program memory

Memory that is used for stack and heap storage for both system and nonsystem applica-

tions. Nonsystem applications are taken from storage memory, uncompressed, and loaded

into program memory for execution.

RF card

A small card shaped device installed in a PDA that allows wireless connection and commu-

nication with a network.

RAM (random

access memory)

You can add applications and data files to RAM or into Flash memory via the DiskOn-

Chip. While flash memory is persistent (as long as the backup battery is charged), RAM is

not and will be cleared when you remove or replace the battery. As you can only suspend

the device, the only way to turn it fully off is to remove the battery or to perform a hard

reset.

ROM (read only

memory)

The operating system (

Windows CE .NET) and applications are pre-installed on ROM

and cannot be removed or modified. These applications are persistent.

rebar A command bar with a gripper bar.

remote access

server (RAS)

A feature that connects a device to a host computer. Windows CE can connect to a remote

access server using direct serial, infrared, and dial-up connections. Windows CE supports

the standard Microsoft Win32 RAS functions; however, it allows only one connection at a

time. RAS functions can be implemented for direct serial connections or dial-up modem

connections.
