Troubleshooting

3 01 2014

To reboot means to discard all continuity in a running device in order to recreate its status and memory from the beginning.

Why do you have to reboot your device occasionally?

Rebooting is sometimes necessary to recover from an error, re-initialize drivers, or hardware devices. A reboot may also occur automatically if the computer or hardware device encounters an error or is overloaded.

The reason can be a hardware malfunctioning or, more likely, an application which does not manage the memory associated to it correctly by interfering with other parts of the memory reserved for other tasks.

Think of it like this:

You want to send money to an account and looked up the account number. Somebody asks you ‘What time do we have the appointment with Mr. Smith?’. After answering your short-term memory containing the account number is deleted or the account number you are sure it’s right now contains transposed digits.

You have to reboot and load your memory again with the account number.

If you don’t look up the account number again your money transfer will fail. Regarding your device an app may execute an unwanted operation which might freeze it e.g. by running into an endless loop. You tap on a control but the app doesn’t react or delivers wrong information to the brain of your device, the processor.

A reboot removes any not-wanted elements associated with apps or the operating system in the device’s memory and trimming it down to the core elements.

Here is a summary of support advices published on Apple’s websites.
The image you see is called a mind map. Maps are useful to visualize and summarize content you usually find in textual descriptions. In this case these are support articles published by Apple. Mind maps are not only images. If you use a mind mapping tool (a perfect one for the iPad is iThoughts HD by Craig Scott, UK) you can expand and collapse topics, use the integrated web browser to read more on topics associated with a link, tap on images to magnify them if needed, export and share the maps.

The alternative file formats have been created with iThoughts HD for iPad (.ITMZ file format). Compatibility to other tools is limited.

Here are the details of this mind map.

Deleting an app …

You should be careful when deleting an app with which you already manage files.

Interactions of an iOS app are limited mostly to the folders associated with it. This limitation is labeled Sandbox-Mode and was designed to increase the security of the filesystem. So if you delete an app the associated files are also deleted.

Summary …

Trust me, I’ve read more than a 1000 knowledge base articles of Microsoft while fighting with flaws in the Windows operating system as well as Office products. Hours of booting, restarting, updating virus scanners, installing patches, localizing buggy drivers, and more annoying tasks abruptly ended with purchasing iOS devices. Admittedly these devices are limited in it’s functionalities but it’s just a question of creativity to compensate this. Reducing the usage of electronic devices to it’s needs can be an advantage. Just focus on essentials.

It turns out that Steve Job’s announcement ‘It just works.’ is true and seamless usage is guaranteed when moving into Apple’s ecosystem. So it’s likely that you don’t need to know any details about troubleshooting on iOS devices. A reboot or the deletion of a buggy app is what you can do if an iOS device causes problems. Apple’s excellent customer service will do the rest if it’s a hardware failure.
