Exponential growth in the number of transistors and the power of processors is expected to decrease in the foreseeable future.
False
IT infrastructure consists of only those physical computing devices and software required to operate the enterprise.
False
In N-tier computing, significant parts of website content, logic, and processing are performed by a single web server.
False
It is much harder to eliminate a cloud service than to remove functionality from a company's core internal systems.
False
Microsoft is no longer the market leader in client/server networking
False
Microsoft is no longer the market leader in client/server networking.
False
the work of the entire network is balanced over several levels of servers.
In a multi-tiered network:
A web server is responsible for locating and managing stored webpages.
OTrue
5, 4, 2, 3, 1
Place the following eras of IT infrastructure evolution in order, from earliest to most recent: 1. Cloud Computing Era; 2. Client/Server; 3. Enterprise Era; 4. Personal Computer; and 5. Mainframe and Minicomputer.
O technology standards.
Specifications that establish the compatibility of products and the ability to communicate in a network are called:
mainframe
The development of TCP/IP occurred during the era.
Allowed computers to be customized to the specific needs of departments or business units
The introduction of the minicomputer:
a virus.
Today's computer transistors are roughly equivalent in size to:
An application server may reside on the same computer as a web server or on its own dedicated computer.
True
Client/server computing is a primary example of decentralized processing.
True
Enterprise infrastructure requires software that can link disparate applications and enable data to flow freely among different parts of the business.
True
In financial services firms, investments in IT infrastructure represent more than half of all capital invested.
True

Interpretations of Moore's law assert that:
computing power doubles cvery 18 months.
Windows Operating System
is an operating system used on most Wintel PCs throughout the world.
Infrastructure-as-a-Service (laaS):
is one type of cloud computing service where users pay only for the computing capacity they actually use.
Metcalfe's Law
states that the value or power of a network grows exponentially as a function of the number of network members.
individual O Nanotechnology
the use of single atoms and molecules to construct microscopic devices
two-tiered client/server architecture.
A client computer networked to a server computer, with processing split between the two types of machines, is called a(n):
Application server
A(n) is used to communicate between a user and an organization's back-end systems.
