Figure 3.5 The. client/server. model. is. used. for. many. different.
applications.
programs.. The. most. predominant. is. Microsoft's. Enterprise.
that.uses.Outlook.as.the.client..You.might.have.Outlook.as.
your.client.on.your.home.computer.as.well,.even.though.your.
home.e-mail.is.hosted.by.your.Internet.provider.
This. might. be. a. little. confusing,. so. take. a. quick. look. at.
the.
client/server.
model.(Figure 3.5)..This.is.a.model.that.is.
used.for.other.applications.besides.e-mail,.so.it.is.important.
to.understand.
In.an.e-mail.system.all.of.the.processing,.directing,.possi-
bly.iltering,.and.storing.of.messages.take.place.in.a.database.
that.might.be.hosted.on.a.server..The.database.might.also.be.
stored.separately.and.simply.accessed.through.a.server.
A. server. is. usually. a. more. powerful. and. higher-capacity.
computer.that.“serves”.more.than.one.desktop.or.workstation.
computer.with.application.features..In.the.case.of.an.e-mail.
server,.it.is.responsible.for.taking.input.of.messages.or.con-
tacts,.calendar.items,.tasks,.and.so.forth,.from.the.computers.
it.serves.and.organizing.those.into.the.correct.storage.space.
(your. e-mail. box. for. instance);. directing. them. to. the. e-mail.
system. they. are. addressed. to;. and. possibly. archiving. them.
or. sending. them. to. a. separate. e-mail. repository.. It. is. also.
responsible.for.collecting.and.properly.distributing.incoming.
e-mail.and.in.some.cases.iltering.those.e-mails.
