MIS 430 Exam 2 Study Guide Solutions
Technology Infrastructure - Ans:✔✔-ontext refers to an enterprise's entire collection of hardware,
software, networks, data centers, facilities and related equipment used to develop, test, operate,
monitor, manage and/or support information technology services
Moore's Law - Ans:✔✔-(paraphrased) the processing capability of computers
will double every (approximately) two years (actually, it has been progressing at a pace of doubling about
every 16-20 months)
Metcalfe's Law - Ans:✔✔-(paraphrased) the value of a network increases exponentially as the number of
users on the network rises (For example, now that a lot of consumers are on the Internet, it is attracting
more businesses.
Role of Technology standards - Ans:✔✔-establish specifications and procedures designed to ensure the
reliability of the materials, products, methods, and/or services people use every day.
consistent protocols that can be universally understood and adopted
Network Attached Storage (NAS) - Ans:✔✔-a server placed on the network with the sole purpose of
providing storage to the users and systems attached to that network

Convergence computing - Ans:✔✔-coming together of two or more distinct entities or phenomena. is
increasingly prevalent in the IT world; in this context the term refers to the combination of two or more
different technologies in a single device
Convergence communication - Ans:✔✔-networks that have arisen as the result of the evolution and
popularization of the Internet as well as the activities, products and services that have emerged in the
digital media
Supercomputers - Ans:✔✔-Very Large, Very High Capacity, Multi-User, Massively Parallel Processing,
Very Fast at Computationally Intensive Applications, Very Expensive, Example: Cray
Mainframe - Ans:✔✔-Very Large, Relatively High Capacity, Usually Multi-User, May or May Not Have
Parallel Processing Capabilities, Relatively Fast Processing, Expensive, Used for "Big Iron" Transaction
Processing and as Corporate Database Engines in Many Organizations Today, Example: IBM
Minicomputer - Ans:✔✔-Medium-sized, Medium capacity, Usually Multi-User but Single-User
Installations Can Be Found, Most Are Single-Processor Machines Although Parallel Processing Models
Can Be Found, Moderately Expensive, Usually Scalable Across A Range of Activity, Used for Main
Processing in Many Small and Medium-sized Businesses or as a "Front-End" Processor to the Mainframe
Computer in Corporate Settings, Examples: DEC VAX series or IBM AS400
Workstations - Ans:✔✔-Cost Between a Minicomputer and a Microcomputer, May Be Multi-User In
Secretarial or Accounting Applications But Often Single-User Machines in Drafting and Design
Applications, Physical Size is Usually Not Much Larger Than a Desktop Microcomputer, Most Have

Extremely Fast Single Processors But A Few Can Be Ordered With Parallel Processing Capabilities,
Examples: SUN Microsystems or Hewlett-Packard Workstations
Microcomputers - Ans:✔✔-Usually Relatively Low Cost, Generally Single-User (at a time) Machines, Very
Prevalent as a Form of Computing, Usually Smaller in Physical Size than Workstations or Minicomputers,
Usually Contain A Single Processor (Although Dual and Quad Processor Machines Can Be Found), Almost
Endless Applications Have Been Made of This Class of Computers, Examples: IBM PC, Apple MacIntosh,
Compaq, Gateway, Packard-Bell, Toshiba, and numerous other vendors
Subcategories of the Microcomputers - Ans:✔✔-Desktops, Luggables, Laptops, Notebooks, Sub-
Notebooks, Palmtops, Personal Digital Assistants (PDAs), Pen-Based Computers, Wearable Tab
Computers, PC-on-a-Chip Computers, Tablets, Smartphones, and numerous other
forms
Virtualization - Ans:✔✔-means to create a virtual version of a device or resource, such as a server,
storage device, network or even an operating system where the framework divides the resource into one
or more execution environments
service-oriented architecture (SOA) - Ans:✔✔-is a style of computer software where services are
provided to the other components by application components, through a communication protocol over
a network. The basic fundamental principles of service oriented architecture is independent of vendors,
products and technologies
