Usually activated by a press of the physical HotSync button on the Palm's cradle (a dock station), this application communicates with various conduits on the desktop PC to install software, backup databases, or merge changes made on the PC or the handheld to both devices. It can communicate with the PC through a physical connection (USB on newer models), Bluetooth or IrDA wireless connections, and direct network connections on devices with networking capability. </p><p>In addition to the conduits provided by the licensee, developers can create their own conduits for integration with other Palm OS applications and desktop products. For example, a time tracking package could provide a conduit to communicate information between Palm OS and Windows executables. </p><p>A Backup conduit included with the HotSync software backs up (and restores, if necessary) most of the data on a Palm OS device. This allows users to hard reset their Palm—thus clearing all of the data—with few noticeable consequences. This also allows users to migrate to new Palm devices of the same Palm OS version, a feature that is helpful to those who lose or damage their device. </p><p>Some models of Palm keep their data storage in <a href="/wiki/Volatile_memory" title="Volatile memory">volatile memory</a> and require constant power to maintain their memory. Although these handhelds attempt to save the contents of memory in low battery situations by not "turning on," leaving a "dead" handheld for an extended period of time can cause this reserve power to be used up and the contents of storage memory to be lost.

Memo Pad is for text only, not for drawings, and text can be entered using the <a href="/wiki/Graffiti_(Palm_OS)" title="Graffiti (Palm OS)">Graffiti</a> alphabet, using hardware or software keyboards, or using the 'paste' function. When Palm devices first became available, some Palm users started to create and exchange Memo Pad documents containing generally useful information, which came to be known as <a href="/wiki/Memoware" title="Memoware">Memoware</a>. </p> <figure class="mw-halign-right" typeof="mw:File/Frame"><a href="/wiki/File:Palmtodo41.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/en/a/a7/Palmtodo41.png" decoding="async" width="160" height="160" class="mw-file-element" data-file-width="160" data-file-height="160" /></a><figcaption>To Do list</figcaption></figure> <p><b>To do list</b> creates personal reminders and prioritizes the things the user has to do. Each To Do List item may also have: a priority, categories (to organize and view items in logical groups), attached Note (to add more description and clarification of the task). <br />To Do List item can be sorted by: due date, priority or category The newer <b>Tasks</b> app features the following improvements: new interface, repeating tasks, alarms, etc. </p><p><b>Preferences</b> (also referred to as Prefs) shows program files with a special preference panel type which are not shown by the normal launcher. Programs can be changed by switching the 'appl' type to 'panl' and vice versa. Palm OS contains approximately 15 preference panels by default and new preference panels can be added just like any other application. </p><p>Preference panels allow users to manage a number of settings, including <a href="/wiki/Graffiti_(Palm_OS)" title="Graffiti (Palm OS)">Graffiti</a> settings, sound settings, text shortcuts, network settings and the system time. </p><p><b>Security</b> (which is a panel on newer Palm OS devices) is used to configure Palm OS's security settings. These include the password needed to display hidden records and unlock the device when locked, as well as set up an automatic lockdown time or inactivity threshold. On the PC, only Palm Desktop honors this password but other PC programs can view everything—in other words, all the data protected by this password can be seen by anyone opening the .dat files using a text editor or word processor. </p> <div class="mw-heading mw-heading3"><h3 id="Common_third-party_core_OS_applications">Common third-party core OS applications</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Palm_OS&action=edit&section=14" title="Edit section: Common third-party core OS applications"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Starting with Palm OS version 5.2, Palm created customized versions of the common PIM application.
