VISUAL NEWSLETTER – MAR 2004
Advances
in computer software have from time to time required that we upgrade our
computers to run the latest software. Older computers are constrained primarily
by processor speed, disk space and RAM memory availability. Occasionally, the
operating system level may also become a problem. Some newer programs will only
run on Windows 98 or newer operating systems.
With
the exception of operating speed, these typical constraints can be upgraded
fairly inexpensively. Processor speed related problems are not so easily fixed.
A computer running at 100 MHz for instance, cannot run
the latest movie trailer regardless of how much memory or disk space it has.
In
some instances operating system degradation can make an otherwise capable
computers run much slower than it did when it was newer. This can sometimes be
remedied by a tune up or a full operating system reload may be necessary. In
either case, if the computer worked ok before, then it can usually be brought
back up to spec.
Before
you throw out an otherwise useful computer, consider the upgrade and
reinstallation possibilities. Slower computers may also work just fine in certain
data entry intensive operations, so relocation may be a viable option. Many
companies offer older computers to employees. As a first computer for a child
or a second word processor, they can still be useful if they are in good
working order. We often can find older computers a home if you no longer have
any use for them.
Older
computers have some useful possible functions. A common one is to use an older
computer as a print server. On Novell networks one can drive up to three
printers with excellent performance and reliability. This is usually superior
to printer sharing.
INTERNET
SECURITY
The
ever increasing onslaught of Viruses, Ad-ware, Spyware, Hackers and unsolicited
E-mail (Spam) has caused seemingly unending aggravation to computer users
across the world. The major Anti-Virus companies have responded with a suite of
products which are commonly known as Internet Security programs. Norton,
MacAfee and others have created these suites to combat all of the above
problems.
Anti-Viruses
have become essential in the Internet enabled workplace. They need to be kept up
to date to be effective however. This means daily updates and weekly scans at
the very least. Even then a new virus can occasionally breach security
especially if you are not also downloading Windows patches.
At
the same time these suites also detect, hunt down and remove Ad-ware and
Spyware which can cause excessive ads to pop up and may relay personal
information to the outside world. As an added benefit, Norton’s Internet suite
also functions to suppress pop-up ads. I found this to be quite effective visiting
sites that I know to be Ad intensive.
Another
function of the suites is Anti-Spam. Unwanted e-mails, guaranteed to make you
rich or enlarge body parts are rampant. These can be effectively blocked by
these suites but you must take care not to block legitimate e-mails at the same
time.
Another
function not to be overlooked in the workplace is Parental Control. This can be
activated to keep employees out of web-sites that they have no business
visiting at work.
The
downside of these suites is cost. This extensive technology costs about $100
per computer. When you consider the cost of repairing virus damage, lost
productivity and corporate liability it may still be a bargain.
