Identify four primary, interrelated reasons for creating clusters of computers. Briefly
describe these.

1. To increase the available computing power by combining the power of
the individual systems.
2. To create fault‐tolerant systems.
3. To create high‐availability systems.
4. To create load‐balancing systems with large workloads.
Graphic User Interface (GUI):

, A form of user interface that allows users to interact with electronic devices
through graphical icons and audio indicators such as primary notation.
COTS (commercial off-the-shelf software):

Inexpensive computers connected together to form a Beowulf cluster
SCSI:
Give this one a try later!
Stands for Small Computer System Interface and is a common interface
bus. It is the standard protocal.
TCP sends a control pacjket to TCP at the WEB site, requesting a connection; this
results in a brief back-and forth series of request and acknowledgments known as
what?

Handshaking
Full duplex:
, Give this one a try later!
Messages are simultaneously carried in both directions
Wide Area Networks (WANs)

networks designed to facilitate communications between users and
applications over large distances—between the various corporate offices
of an international organization that are located in cities all over the world,
Public-Key (Asymmetric) encryption:
Give this one a try later!
A process that uses a pair of related keys one public key and one private
key to encrypt and decrypt a message and protect it from unauthorized
access or use.
Modem:

A device used to convert Ethernet signals from a computer or router to
analog signals for transmission over the phone line or cable system and
vice versa.
