USB/USB2.0-is a Universal Serial Box-a serial bus that acts like a special purpose area network and enables you to plug in an increasing number and variety of USB devices,including speakers,mice,cameras,keyboards and sound modules, without having to open or even restart your machine.It benfits from a relatively high data transfer rate and uses a standard PC connection that supports up to 63 devices.
What Devices and implications?-
Im indebted to other members of group who have provided detailed explanations of each of the devices.All of the devices allow connection to various degrees of CD-Rom,DVD,digital cameras,music software/hardware,keyboards,plugins,effects etc.The implications I would imagine are that some of these peripherals are not compatible with each and every device and may limit their use.If the latest plugin which a musician is using freely on his home PC and now wishes to transfer/use in the studio isnt compatible with the PC in the studio it could lead to loss of business.
Ive found some good references at Rane Audio Reference accessed through Audio Courses website and at www.prosound.web which gives you access to "The World of Audio Recording" by Dave Casey, a Tascam Product Specialisst.I also found an interesting "What You Need" article at www.computermusic.co.uk
CPU--a Computer Processing Unit which is the main component in a computer microprocessor and it performs calculations and executes instructions.It is cnnected directly to motherboard.
SOUNDCARD-is a portal to allow music in and out of computers.It enables computer to become a muilt track recorder.This card slots into motherboard.Common makes are Aardvark,Echo and Digital Audio Labs all of which have varying features and speeds. |

Aidan I was searching for something when I came accross this in another forum.
Q: How fast is USB 2.0?
A: USB 2.0 is designed to work at up to 480 mbps per second.
Q: Is USB 2.0 backwards compatible with version 1?
A: USB 2.0 is fully backward compatible with USB v. 1.1
Q: What are the differences between versions 1.1 and 2.0?
A: Version 1.1 supports two speeds, 1.5 and 12 mbps. USB 2.0 supports 1.5, 12 (making it backward compatible), and 480 mbps.
USB 2.0 will likely not completely replace version 1.1. I/O devices, such as keyboards, mice, and joysticks, have all the bandwidth they need in USB 1.1.
Q: How does USB 2.0 compare with FireWire?
A: Some say USB 2.0 will likely not replace FireWire (IEEE 1394/FireWire/I-link, etc.) because FireWire has established its place firmly within many industries, such as the camcorder industry.
Q: Will Microsoft support USB 2.0 in its 9.X systems?
A: Microsoft will not provide USB 2.0 support for the Windows 9x platform or Windows NT® 4.0. 3rd party vendors will make support available for operating systems other than Win 2000 and Win XP.
Q: What operating systems will it support?
A: Windows 2000, Windows XP and all future Microsoft operating systems.
Q: Is the drive stack between Windows 2000 and Windows XP different?
A: Yes.
Q: Then how will USB 2 work on Windows 2000?
A: “To support USB 2.0 on Windows 2000, a parallel (new) driver stack is needed. This driver stack will consist of Usbport.sys, Usbhub20.sys and Usbehci.sys. A host controller-specific coinstaller (Hccoin.dll) will also be provided to ensure proper Windows Update installation in the Windows 2000 scenario.”
Q: How do I ensure that my USB 2.0 devices work on Windows XP?
A: QFE 4 for HCT 10.0 includes tests to ensure that USB 2.0 Hi-Speed devices and USB EHCI host controllers work properly with Windows XP
Q: What makes USB 2.0 able to hold 480 Mbs?
A: USB 2.0 will specify a microframe, which will be 1/8th of
a 1msec frame. This will allow USB 2.0 devices to have small buffers even at high data rates.
Q: Who was involved in the development of USB 2.0?
A: Intel, Microsoft, Compaq, Hewlett-Packard, Lucent, Philips, and NEC were all involved in the development of USB 2.0.
Q: Are there any other names for USB 2.0?
A: USB 2.0 has been dubbed “USB Hi-Speed,” while USB 1.1 is now to be called “USB Basic Speed.”
Q: Will I have to get a new USB hub?
A: Yes. You may use a USB 1.1 device in a USB 2.0 hub, but not the other way around. If you plug a USB 1.1 into a USB 2.0 chain, all USB 2.0 devices will operate at 1.1 speeds.
Q: What is the maximum length of a USB 2.0 cord?
A: The maximum length is 16.4 feet.
Q: What do I need to upgrade my system to USB 2.0?
A: You will need a USB 2.0 host controller card, a USB 2.0 driver and an OS that supports USB 2.0. It should cost from US$80 to $150.
Q: When will USB 2.0 be available for my laptop?
A: Laptop venders will not include 2.0 support for some time, although third party companies have already debuted USB 2.0 hardware for laptops.
