as a Second LanguageWhat Makes a Good Computer
A
LOOK OUTSIDE The
front of the computer case contains a power button for
turning the computer on and off. Almost all computers also have a
reset button for re-starting the computer without
having to turn the power off. A system reset is sometimes necessary when
the computer stops responding to your keyboard commands or mouse clicks.
This can happen when the CPU receives an instruction that it "does
not understand" due to a problem with the computer program that is
running at the time. It is easier on all the delicate electronics within
the computer to perform a reset than a complete power on. In fact,
whenever you do turn your computer off, it should never be turned on
again without waiting at least 60 seconds.The
front of the computer has several openings for inserting electronic
media. Media is a fancy word for floppy disks,
CD-ROMs, computer tapes and computer cartridges.At
first glance, the back side of the case is a bit more intimidating.
You'll see a receptacle for connecting the power cord to a household
plug. In addition, there are several jacks or
ports for connecting peripheral devices. For example,
there are ports for hooking up your color monitor, a port for the mouse,
the keyboard, a joystick, a printer or scanner, an external modem, etc.Speaking
of power cords, one of the best investments you can make for your
computer is a surge protector. You plug the computer
into the protector and then connect the protector to a normal household
plug. In the event of a high-voltage irregularity, the surge protector
will save your motherboard and all internal electronics from being
damaged. This could save you thousands of dollars. A good protector (UL1449
approved) only costs about $100.00.Better
yet, seriously consider purchasing a UPS, or Uninterruptible
Power Supply. Besides containing a
surge protector, a UPS includes a battery that will keep your computer
and monitor running even if there is a total blackout. You'll have about
seven minutes to complete whatever you are working on and shut down the
computer properly. Every year there are thousands of computer users that
lose valuable work due to sudden and unexpected power disruptions. |
