Part I:
A. Locate a research and/or educational center
The International Computer Music Association (www.computermusic.org) is an
organization dedicated to serving all aspects of computer music, including technical,creative and performance. Some of the functions of the ICMA include sponsoring the
International Computer Music Conference and presenting ICMA awards.
The ICMA began sponsoring the annual International Computer MusicConference in 1974. The ICMC serves as a gathering of computer music artist and
professionals, combining both technical paper presentations with computer music
concerts. The ICMC is one of the worlds only computer music gatherings. The ICMA
also presents awards during the ICMC to some of the best performances.One other important aspect of the ICMA is serving the computer music
community. The ICMA provides a working membership directory to allow greater
networking among the international computer music community and publishes the
computer music newsletter ARRAY. The membership directory was designed to allowthe cross-influence of those in the computer music and related fields. By listing
members names and contact information, the ICMA hopes that members will beencouraged to interact with each other.
B. Locate an artist
Laurie Spiegel, an artist featured on the Electronic Music Foundation website,
was one of the pioneers of electronic music. Her work has been on all fronts of electronic
music, including writing software, designing electronic music systems, and working withearly synthesizers, as well as composing her own work. Her CD, Obsolete Systems, is just
one in a long line of artistic accomplishments.Spiegel did most of her work with analog synthesizers during the 60s, 70s andearly 80s. Her early work, including The Expanding Universe, was generated with
compositional algorithms to make music in an accessible, minimalist vein. Many of her
early melodies were very folk like, a trend which would change with her later works.Spiegels more recent music has become much darker and much more complex
than her earlier work. According to composer Kyle Gann, Minimalism may still aptly
describe the slow movement of pitch in these pieces (Unseen Worlds), but it gives no hint
of their complex timbres, glacial momentum,and cathartic climaxes. Such vibrant,expressive music could only have come from a composer who put her intuition and
imagination first, yet who had the immense technical know-how needed to meet the
challenges they posed. Spiegel has definitely proven herself to be one of the premierartists working on the frontier of electronic music.

speed internet access over existing phone linesAIFF Audio Interchange File Format; standard Macintosh digital audio format
Analog non-quantized information
AppleTalk The networking protocol that comes with every Macintosh
ASCII American Standard Code for Information Interchange; the ASCII character set
contains 128 7-bit characters which are used for data interchange on and betweencomputers.
Baud Rate The rate (kB/S) at which a modem transfers information.
Binary Numbers Numbers represented in Base 2 (i.e. only using 1 or 0)
Bits A bit is a single electronic switch that can be either on or off, which represents one
binary digit, either 1 or 0.
Boot To take some sort of action to initiate a computer, for example, turning on
primary power, or restarting a computer.
Bytes A byte is a group of 8 bits.
CD Compact Disc; an optical digital recording medium which stores audio, visual or
other information for playback.
CD-R Compact Disc Recordables; a CD which allows information to be written to it a
single time, by way of a CD-R drive. Digital information is inserted by a laser which
etches pits into crystals on the bottom side of the CD.
CD-ROM Compact Disc Read Only Memory; an adaptation of the CD which was
designed to store computer data in the form of text and graphics.
CD-RW Compact Disc ReWriteables; a CD which allows information to be written to
it multiple times, through a CD-RW drive.
Client A client is a computer program designed to work with a server program. A client
program is designed to make requests from a server program, which would fulfill that
request. This idea is applied to all aspects of computing, especially on networks, where
information is sent from a server to a client.
Compression The idea of reducing the number of bits required to store data, byapplying a mathematical algorithm.
CPU Central Processing Unit; the part of a computer that controls input and output
functions, and performs logical and arithmetic operations on data.
DAC Digital Analog Converter; a device which converts digital sound into analogsound.

Data Files A data file is a group of bits associated with each other which represent a
some kind of digitally stored information, such as an image or a document.
Datagram An independent portion of data which is sent from a source computer to a
destination computer. The information contained in this packet does not rely on previousor future exchanges from the source to the destination.
Digital Information in the form of discreet points.
DNS Domain Name Server; a software program that translates the domain names of
internet sites into IP addresses which a browser can understand.
Domain Name A labeled form of an internet address, usually written with words as tomake them easier to remember.
Drive A drive is a device connected to your computer from which digital information is
read from a storage medium.
DVD Digital Versatile Disc; an optical disc which can hold up to 17 MB, if it is two
layered and double sided. It uses similar technology to a CD.
Ethernet The most widely used Local Area Network technology; it provides network
access through coaxial cable and a network card.
Firewire A Macintosh version of a High Performance Serial Bus for connecting
devices to a computer. The firewire cable has three pairs of wires, two for data and onefor power, and can provide data transfer speeds of up to 400 mbps.
FTP File Transfer Protocol; a standard internet protocol for exchanging files over the
internet between computers.
GIF Graphics Interchange Format; a format for storing graphical information which is
commonly used on the internet. The patent for the GIF algorithm is owned by Unisys.
GUI Graphical User Interface; the part of a software program which representscommands and operations graphically for a user, making it easier and more accessible for
the user to perform complex operations.
HTML HyperText Mark-up Language; the standard file format for web pages which
are viewed via an internet browser.
Internet a worldwide system of computer networks in which one computer on thenetwork, with the appropriate permissions, can obtain information from another computer
on the network.
IP Internet Protocol; the numerical representation of an internet address which is
understood by an internet browser to connect to an internet site.IPOS input/process/output/storage model; the model used to represent computers in
which input devices (keyboard, mouse) connect with the process devices (CPU).
Information can be stored on storage (hard disk, optical discs) and/or outputted (Video,
Audio).
ISDN Integrated Services Digital Network; a set of standards for digital information
transmission over ordinary copper telephone wire.

access to the internet.
Java a universal programming language designed to work on multiple platforms. This
aspect makes it good for the Internet, where many users may be connecting to websitesvia different operating systems.
JavaScript A slimmed down script version of Java designed to provide scripting for
Internet browsers.

Packets Synonymous withDatagram. An independent portion of data which is sentfrom a source computer to a destination computer. The information contained in this
packet does not rely on previous or future exchanges from the source to the destination.
Parallel Data Parallel data is parallel because each binary bit of the computer is
connected with one bit of the device. This is faster than serial data transfer, however, itrequires as many wires as bits the computer uses.

altered. This generally contains information which allows your computer to be booted up
from its original specifications.
Serial Data Data which goes over a serial connection, that is, a connection where thereis only a single wire from the computer to the device. Data is converted into a serial data
stream, and then sent a single bit at a time over the wire.
