We have had so many
requests for our cabling guide, we decided to replicate it on our website.
Please feel free to review and copy as needed.
Parallel Cabling Guide
When IBM introduced the PC, in 1981, the
parallel printer port was included as an alternative to the slower serial port
as a means for driving the latest high performance dot matrix printers. The
parallel port had the capability to transfer 8 bits of data at time whereas the
serial port transmitted one bit at a time.
IEEE 1284 Cabling Guide
The "IEEE Std.1284-1994 Standard
Signalling Method for a Bi-directional Parallel Peripheral Interface for
Personal Computers", is for the parallel port what the Pentium
processor was to the 286. The standard provides for high speed bi-directional
communication between the PC and an external peripheral that can communicate 50
to 100 times faster that the original parallel port.
Serial Cabling Guide
Serial means one event at a time. It is usually
contrasted with parallel, meaning more than one event happening at a
time. In data transmission, the techniques of time division and space division
are used, where time separates the transmission of individual bits of
information sent serially and space (on multiple lines or paths) can be used to
have multiple bits sent in parallel.
SCSI Cabling Guide
SCSI was created to satisfy the need for a more
flexible, faster, command-controlled interface for hard disk drives and other
computer peripherals. Despite the term "small" in its name, SCSI
is large. It is large in use, in market impact, influence, and unfortunately in
Monitor Cabling Guide / Video Display
Since there are many different ways to specify a
video card's capabilities, and so many potential resolutions, color modes, etc.,
video standards were established in the early years of the PC, primarily by IBM.
The intention of these video standards is to define agreed upon resolutions,
colors, refresh modes, etc., to make it easier for the manufacturers of PCs,
monitors, and software to ensure that their products work together.
USB Cabling Guide
USB (Universal Serial Bus) is designed to be a "plug
& play" interface between a computer and add-on devices such as audio
players, joysticks, keyboards, telephones, scanners, and printers. USB allows
new devices to be added to computers without having to turn the computer off.
USB Supports a data speed of 12 megabits per second.
Network Cabling Guide
Local Area Networks (LAN) have become the
prevalent way of sharing information. As this is probably the fastest moving of
cabling media, by the time you have finished reading this, another new product
will be on the market !
