In-Depth Information
can. also. include. information. on. iles. that. were. opened. on.
network.drives.
Any.documents.or.iles.that.you.open.with.an.application.
will.also.create.a.record.in.the.registry.and.in.other.tracking.
iles..The.document.or.ile.will.include.a.record.of.when.it.was.
last.accessed.or.modiied.
When. an. application. is. updated. or. patched,. similar.
changes.happen.as.during.the.installation.process..Data.are.
stored.temporarily.in.volatile.memory.and.in.temporary.fold-
ers..Changes.are.made.in.the.registry,.and.logs.are.created.or.
changed.to.relect.the.updates.
In.many.operating.systems.there.is.a.process.recorded.in.
the.registry.that.creates.a.copy.of.all.of.the.data.as.the.data.
exist.before.any.new.applications.are.added..This.is.called.by.
several.different.names.such.as.
restore.points.
or.
shadow.cop-
ies
,.but.in.essence.it.is.a.rollback.or.restore.function.that.allows.
one.to.go.back.to.a.known.good.coniguration.of.your.com-
puter.should.the.addition.of.a.new.application.cause.problems.
This.also.creates.data.and.records.in.the.registry,.in.logs,.
and.in.speciic.system.restoration.iles.that.can.contain.very.
useful.information.
The.point.of.all.this.description.of.what.happens.during.
different.activities.on.your.mobile.device.is.to.illustrate.all.of.
the. ways. data. can. be. added. or. changed. on. these. types. of.
computing.tools..All.of.this.information.can.become.relevant.
when.you.need.to.understand.the.answer.to.the.questions,.
“what.happened,.when.did.it.happen,.how.did.it.happen,.and.
who.did.it?”
Finally,.we.need.to.consider.what.is.unique.about.mobile.
devices.as.opposed.to.their.more.stable.cousins,.the.desktop.
computer.or.workstation.or.server.
The.bottom.line.is.that.in.the.areas.we.talked.about,.there.
is.not.a.lot.of.difference..Mobile.devices.will.tend.to.use.smaller.
form-factor.storage.and.will.usually.be.contained.in.one.piece.
of.hardware.as.opposed.to.nonmobile.devices.
Some. mobile. devices. will. have. the. capacity. to. attach.
peripheral. hardware. such. as. keyboards,. speakers,. mice,. or.
