together,.enable.a.computer.system.to.operate..One.of.
the.main.components.of.system.software.is.the.operat-
ing.system.of.the.computer.(e.g.,.Microsoft.Windows

Tool:. A.utility.program.used.primarily.to.create,.manipulate,.
modify,.or.analyze.other.programs,.such.as.a.compiler.
or. an. editor. or. a. cross-referencing. program,. or. per-
form.maintenance.and/or.repairs.on.system.hardware.
or. application. software.. Tools. include. Hex. editors,.
disk. checkers,. ile. backup. and. recovery. programs,.
and. so. forth.. Tools. are. powerful. pieces. of. software,.
and.the.use.of.tools.within.an.organization.should.be.
restricted.to.those.personnel.who.have.either.received.
the. proper. training. or. have. otherwise. proven. their.
competence.in.the.use.of.such.software.
Toolkit:. A.collection.of.tools.with.related.purposes.or.func-
tions.(e.g.,.antivirus.toolkit,.disk.toolkit,.etc.).
Uninterruptible Power Supply (UPS):. A. vital. piece. of.
hardware.that.should.not.be.overlooked..Without.it,.a.
power.“outage”.or.even.a.surge,.can.shut.down.your.
systems.within.seconds..If.this.happens.on.a.Windows.
PC,. the. consequences. are. unlikely. to. be. more. than.
annoying.and.perhaps.the.loss.of.the.work.you.were.
currently.working.on..However,.if.your.server,.running.
Windows.NT,.2000.or.UNIX,.suddenly.has.the.power.
cut,.the.consequences.can.be.more.serious,.as.(poten-
tially).hundreds.of.iles.can.be.left.in.an.“open”.state.
that,.in.the.worst.scenario,.could.prevent.the.system.
from.rebooting.properly,.or.even.at.all.
.
. Therefore,. the. purchase. and. installation. of. a. suit-
able. sized. UPS. is. vital.. Because. it. contains. its. own.
battery(ies).it.will.not.only.prevent.damage.from.sud-
den.power.surges,.but.it.can.continue.to.run.your.sys-
tems. for. between. 15. minutes. and. 1. hour. (or. more),.
thus.allowing.an.orderly,.but.speedy,.close.down.
.
. However,.a.UPS.is.not.supposed.to.allow.the.system.
to.be.operated.for.any.length.of.time,.and.to.provide.
