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.
