Mis Test 3 Set 1 Ch. 7

Front 1

a software architecture perspective that focuses on the development, use, and reuse of small self contained blocks of code (called services) to meet all the application software needs of an organization

Back 1

service oriented architecture (SOA)

Front 2

generally a relative term meaning the structure beath a structure. implies different layers of structure, which provide support or services

Back 2

infrastructure

Front 3

refers to the capability of two or more computing components to share information and other resources, even if they are made by different manufacturers

Back 3

interoperability

Front 4

involves little or not sharing of IT and other resources such as information.. generally arises from users or departments developing their own systems or applications

Back 4

decentralized infrastructure

Front 5

involves sharing information systesm in one central area or on one central mainframe

Back 5

centralized infrastructure

Front 6

invovles distributing the information and processing power of IT systems via a network ( the first true network infrastructure.)

Back 6

distributed infrastructure

Front 7

has one or more computers taht are servers which provide services to toher computers, called clients.

Back 7

client/server infrastructure (or client/server network)

Front 8

the IT system is partioned into tiers (or layers) where each tier performs a specific type of functionality.

Back 8

tiered infrastructure (layerd)

Front 9

is the most basic setup because it involves a single tier on a single machine

Back 9

1 teir infrastructure

Front 10

the basic client/server relationship. in essence, the client handles the display, the server handles the request and the application tier is contained on one or both of the two tiers.

Back 10

2-tier infrastructure

Front 11

the most common approach used for web applications today

Back 11

3-tier infrastructure

Front 12

balances the work of the network over several different servers can contain any number of tiers. starts with basic 3 tier model and expands on it to allow for greater performance, scalability, and a host of other benefits.

Back 12

n-tier infrastructure

Front 13

the process of continuously measuring system results and comparing those results to baseline values a system seeks to attain

Back 13

benchmarking

Front 14

baseline values a systems seeks to attain

Back 14

benchmarks

Front 15

means doing something right wihle ---- is doing the right thing

Back 15

efficiency, effectiveness

Front 16

most infrastructure centric metrics today in the IT world are

Back 16

efficiency metric

Front 17

typically a measure of the efficiency, speed, and/or capacity of technology.

Back 17

infrastructure centric metric

Front 18

infrastructure centric metrics include

Back 18

throughput, transaction speed, system availability, accuracy, response time, scalability
