Q: What does USB stand for?
A:
It stands for Universal Serial Bus
Q:
What Is USB?
A: USB is a specification that allows computer
peripherals to be attached to the outside of the computer.
It eliminates the need to install cards into dedicated
computer slots and reconfigure the system. USB is
really an ultimate plug-n-play specification that
no switches or jumpers are required to configure.
One of the top benefits from USB is that users can
install hardware without needing to reboot their computers.
USB allows up to 127 devices to run at the same time
on the bus, with hubs connecting to devices to the
bus. The USB also provides a much higher transfer
rates than the traditional RS-232 or parallel-port
devices.
· One standard connector
type - "one-size-fits-all."
· Hot insertion and
removal - now you can attach and detach peripherals
while your system stays up and running.
· Chain devices together
- USB allows some peripherals to incorporate "hubs"
that serve as connection points for other devices.
This lets you use more than one USB-compatible device
at a time.
· Automatic installation
- when a USB-compatible peripheral is connected, PCs
with USB automatically install and configure the necessary
drivers and system resources.
· Separate power cord
not required - most USB devices get their power through
the USB bus (connection) itself, so only one cable
is needed.
· Faster - USB transfers
data 10 times faster than traditional serial ports.
Q:
What devices support USB?
A: Almost any I/O (Input/Output) device can
be used with USB. They include Mice, Keyboards, Joysticks,
Scanners, Monitors, Zip Drives, Telephones, Cameras
and Printers.
Q:
What is USB 2.0 and will it replace the original?
A: USB 2.0 runs at a whopping 480 Mbps and
features complete backward compatibility with the
original USB. USB 2.0 will most likely not completely
replace its predicator because, simply, a keyboard
or mouse doesn’t need 480 Mbps
bandwidth. While peripherals won’t
utilize 2.0, it will be great for web cams, digital
cameras, etc.
Q:
How fast is USB?
A: USB is designed to run at 12 Mbps with
a sub-channel running at 1.5 Mbps.
Q:
I have Windows 95, Can I still use USB?
A: The original Windows 95 cannot use USB
no matter whether you have USB or not. You need to
have Windows 95 OSR 2.1 (Service Release). If not
you can download the supplement for Windows 95B.
Q:
Will I need special software to run USB with other
Operating Systems?
A: No, what you need is Windows 95B ,Windows
98, Windows 2000, or MacOS 8.5 (found in iMac and
G3 systems). The operating systems pretty much cover
the software side. If you got a USB device, either
the operating systems have the necessary drivers or
the manufacturers ship with the required software/drivers
for the hardware.
Q:
I don't have USB, Can I add it to my PC?
A: You must have an available PCI slot to
install USB PCI card. OS requirement is Windows 98
or Windows 95 OSR2.
Q:
Is USB support stable?
A: Good question. USB is a relatively new
specification, Windows 98 was really the first OS
to have what Microsoft considered full USB support.
Unfortunately while the majority of USB devices work
fine, Windows 98 did have many USB related problems
