On Apple's mobile devices, apps can exist in any of five states of
execution:

* not running: the app has been terminated or has not been launched
since the device was restarted

* inactive: the app is in the foreground but not receiving events (for
example, the user has locked the device with the app active)

* active: the normal state of an app while in use

* background: the app is no longer frontmost but is still executing code

* suspended: the app is still resident in memory but is not executing
code

When you switch away from an app, the OS moves the app from active to background state. Most apps usually then go from background to suspended
in a matter of seconds. Suspended apps remain in the device’s memory temporarily so they can resume more quickly if you switch back to them;
but they aren't using processor time and they’re not sucking battery
power.

If you launch a memory-intensive app, such as a game, the OS will
automatically purge some suspended apps from memory and move them to the
not running state to free up memory for the memory-intensive app you
launched. Those previously suspended apps will be completely removed
from memory and will launch from scratch the next time you tap their
icon.

Most apps do not run in the background. The OS gives all apps a default
five seconds after you switch from them to wrap up operations in
preparation for being suspended. After this five-second period, the OS automatically suspends the app’s operations.

If an app developer believes they need further background processing
time, they can design the app to declare a specific task as background
task which allows the task to run for up to about ten minutes of
background running time before it is forcibly suspended by the OS.

So all apps get five seconds of background execution allowing them to
clean things up when you switch away from them. And some apps can
request a ten-minute extension for longer processing tasks. But there
are a small number of apps that genuinely need to run in the background,
either indefinitely or periodically. The OS restricts this background
activity to exactly five kinds of apps:

* apps that play audio while in the background state

* apps that track your location in the background (for instance a
turn-by-turn GPS navigation app needs to be able to give you voice
prompts even if another app is active)

* apps that listen for incoming voice-over-IP (VOIP) calls (for instance
Skype needs to be able to receive incoming calls while the app is in
the background)

* apps that you allow to refresh their data in Settings > General >
Background App Refresh

* apps that receive continuous updates from an external accessory in the
background

many apps can run in the background, notably navigation, audio, voip
and for a brief time to complete a task, such as finishing an upload.
apps can also check for periodic updates, such as the weather (it's not
like the weather will change minute to minute).

for most apps, running in the background does not make any sense. it's
not like you can play a game or edit a photo while the app is not
frontmost.

What are they called in generic terms?

background apps.

The question was which ones are always active no matter if they have been
force closed? Phone and Messages were two that came to mind.

Can’t apps such as GPS or weather be disabled or force closed to the point where they are not active in the background?

that's because phone calls and text messages are fundamental features
of a phone.

apps that do run in the background should have a 'stop' feature so that
they are not active. for example, a play/pause button in an audio app
or a cancel trip button in a navigation app.

force-quitting is only needed if there's no other option to get the app
to stop (or if it crashed).

It's Unix. There are lots of background processes running all of the
time. Most are part of the operating system and Apple system services.

i did answer, and yes there are others, which i said in the very first
reply.

those two apps are part of ios and largely wrappers on system services.

third party apps do not remain active if they are force-quit (or
stopped within the app).

this is not complicated.

so I
assumed you didn¹t know.

you assumed wrong.

I really hate it when apps vanish and I have to start over on whatever I
was doing. Like using iOS' camera app and then going back to the
previous app and loses where I was! :(
