In-Depth Information
Finally,. depending. on. the. operating. system,. referential.
information.about.the.application.such.as.the.location.of.all.
those.related.iles.is.stored.in.some.type.of.operating.system.
database.or.registry.
All.of.the.data.are.organized.and.stored.in.the.appropriate.
places.each.time.you.add.a.new.application.to.your.mobile.
device.. This. process. is. the. same. on. any. type. of. computer.
but.will.change.in.some.respects.depending.on.the.operating.
system.the.computer.employs..We.discuss.different.operating.
systems.in.a.future.chapter.
Also,.at.the.end.of.the.installation.process,.the.data.stored.
in.random.access.or.volatile.memory.will.be.deleted.or.allowed.
to.be.written.over.by.being.lagged.as.no.longer.necessary..In.
our.earlier.discussions.of.how.memory.works,.we.looked.at.
how.that.happens.and.exactly.when.and.how.that.data.actu-
ally.disappear.
Finally,.the.iles.that.were.stored.in.the.temporary.folders.
are.sometimes.(but.not.always).deleted.at.the.end.of.the.install.
process..It.is.important.to.note.that.sometimes.data.are.not.
deleted..That.can.create.an.interesting.source.of.information.
and.it.can.also.create.problems.if.you.begin.to.get.short.of.
storage.room,.just.by.virtue.of.clogging.up.your.data.system.
and.affecting.the.eficiency.of.your.device.
When.you.access.an.application.to.use.it,.several.different.
records.are.created.and.data.changes.or.are.added.
Most. devices. have. some. kind. of. logging. that. tracks. the.
activity.on.the.device..Those.logs.will.relect.when.an.applica-
tion.is.accessed.or.shut.down..Any.system.iles.that.need.to.
run.for.the.application.to.work.will.start.up.and.create.changes.
on.the.device,.starting.or.stopping.related.services.that.need.
to.run,.such.as.sound,.keyboard,.mouse,.and.monitor.
All. of. these. changes. may. be. recorded. in. the. aforemen-
tioned.logs.and.can.also.be.recorded.in.the.registry..The.reg-
istry.often.tracks.when.applications.start.and.keeps.a.record.
of.recently.accessed.iles.and.applications.
Finally,. several. data. iles. also. track. the. activity. on. the.
device,.some.of.which.speciically.track.Internet.activity,.but.
