This Week’s Meeting
Start with MS-Config – which
we haven’t had time for at the last couple of meetings. Then miscellaneous
topics from the last few handouts and question and answer session.
Digital Camera
(information from Yahoo Internet Life – June, 2001)
Shopping for a digital camera?
Digital cameras cost anywhere from $100 to $3500 or more. Generally speaking,
the more expensive the model, the better the resolution of the photos it
takes.
What do you plan to do with
the photos? A camera’s resolution is measured in units called pixels; the
higher an image’s pixel count, the better the resolution. If you want images
suitable for exchanging via e-mail, a submegapixel camera (one that will
produce a picture containing fewer than 1 million pixels) is sufficient.
If you want to print your pictures, you’ll need a megapixel camera. If
your intention is to convert your picture into an 8x10 print, you will
require the resolution power of a 2-megapixel or 3-megapixel camera.

and amateur photographers are saying about the latest cameras, check these

Extension Cable for a Monitor
We have had a few people ask
about this because they would like to move their monitor a little further
away. We don’t know how well they work; but such an cable does exist. There
is one in the Radio Shack catalog called --- 6 foot extension cable for
a VGA monitor – which sells for $14.99 – it is Radio Shack number, RSU
10288497.
Graphics Cards
Video Chip – The CPU of the graphics card – sometimes called GPU
(graphics processing unit).
TV/Video Out Chip – With this chip, you can display images from
your PC on your TV. It converts the video card’s digital signal into an
analog signal that is compatible with your TV.
DVI Out – Many video cards support flat-panel monitors.
Svideo Out – This is the jack you would use to connect your
PC to a TV, using a Svideo cable.
Monitor Out – This is the standard port you would use to connect
your PC to your monitor.
Strange Sound Mixer Setting
Remember our program on using
Sound Forge to input from a cassette tape and save it on your computer.
You connect the tape player into the LINE IN jack on the back of
your sound card and check your mixer to see that it is looking at
the LINE IN for the record mode. We recently came across a new system that
uses one of the many SoundBlaster boards. The mixer in this computer would
not work correctly when using the LINE IN for the record mode. We had to
use the What U Hear setting from the mixer.
Serial ATA
As new as ATA/100 is, its replacement
is already on its way. The new 150MBps or more Serial ATA interface, backed
by Maxtor, Seagate, Intel and others, could debut later this year. Serial
ATA devices use skinnier cables than EIDE’s that are easier to manipulate
in the confines of computer cases and don’t block airflow as much. The
Serial ATA Working Group says it should facilitate faster future interfaces
and easier setup than EIDE. Best of all, the Group predicts adapters will
let Serial ATA controllers connect to the millions of legacy EIDE hard
drives in the world.
As hard drives have become
much faster at reading and writing data, manufacturers have been inventing
faster interfaces to handle the traffic. EIDE interfaces have many names
including ATA (Advanced Technology Attachment) and UltraATA. All are interchangeable
and backward compatible with older EIDE (Enhanced Integrated Drive Electronics),
PIO (Programmed Input/Output) and DMA (Direct Memory Access) drives. Finally,
the subset ATAPI (ATA Packet Interface) lets CD, DVD, and removable cartridge
drives such as Zip drives connect to the EIDE controller.
Most EIDE motherboards come
with a built-in controller, with two channels labeled primary and secondary.
If your motherboard was made before late 1999, its controller probably
doesn’t support ATA/66 or ATA/100.
EIDE sockets have either
39 or 40 pins in two rows. One connector on your EIDE ribbon cable plugs
into these pins, while its other connector or two are for your hard drive,
CD-RW drive or other device. Each channel can handle two devices, a master
and a slave. The master device controls the slave. You can configure a
device as a master or slave using its jumper switches. Modern EIDE controller
cards automatically sense your hard drive’s interface speed. On more thing:
ATA/66 or ATA/100 drives and controllers require a special ribbon cable
with extra ground wires for top speeds. It has 40 pins like a regular EIDE
cable, but 80 wires instead of 40. ATA/66/100 drives can use 40-wire EIDE
cables, but only up to ATA/33 speeds.

CloneCD
A member of the group mentioned
this one. They sell a software program called CloneCD for $49 that will
duplicate a CD so that you can make a backup of your software.
