True or False
In Evaluate various IT infrastructures,
These elements include the computers, servers, networking, data, storage, physical and virtual
facilities as well as software, processes, policies, staffing, training, security, mobile and virtual
functionality, and cloud-based services that make up the IT infrastructure.
True
an electronic device for storing and processing data, typically in binary form,
according to instructions given to it in a variable program.
Computers
a computer or computer program which manages access to a centralized resource or service
in a network.
Servers
- the linking of computers to allow them to operate interactively.
Networking
the quantities, characters, or symbols on which operations are performed by a computer,
being stored and transmitted in the form of electrical signals and recorded on magnetic, optical,
or mechanical recording media. Facts and statistics collected together for reference or analysis.
data
A ________________ is a highly realistic digital representation of a data center
(primarily). The term virtual in Virtual Facility refers to the use of the word as in Virtual Reality
rather than the abstraction of computer resources as in platform virtualization. The VF mirrors the
characteristics of the physical facility over time and allows modeling all relevant characteristics of
a physical data center with a high degree of precision.
Virtual Facility (VF)
(VF)
Virtual Facility
- the programs and other operating information used by a computer.
Software
- a series of interdependent operations carried out by computer.
Processes
- are generally adopted by a governance body within an organization.
Policies
- provide (an organization, business, etc.) with staff.
Staffing
- the action of teaching a person or animal a particular skill or type of behavior.
Training
- refers to all the measures that are taken to protect a place, or to ensure that only
people with permission enter it or leave it.
Security
A ___________________ is any service made available to users on demand via
the Internet from a cloud computing provider’s servers as opposed to being provided from a
company’s own on-premises servers. Cloud services are designed to provide easy, scalable
access to applications, resources and services, and are fully managed by a cloud services
provider.
cloud-based services
__________________ refers to the composite hardware, software, network resources and services
required for the existence, operation and management of an enterprise IT environment. It allows
an organization to deliver IT solutions and services to its employees, partners and/or customers
and is usually internal to an organization and deployed within owned facilities.
IT infrastructure
IT infrastructure is composed of seven major components:
[]Computer hardware platforms
[]Operating system platforms
[]Enterprise and other []software applications
[]Data management and storage
[]Networking and telecommunications platforms
[]Internet platforms
[]Consulting and system integration services
[]Computer hardware platforms
[]Operating system platforms
[]Enterprise and other []software applications

[]Internet platforms
[]Consulting and system integration services
Seven major components of IT infrastructure
_____________ include client machines and server machines, as well as
modern mainframes produced by IBM. Blade servers are ultrathin servers, intended for a
single dedicated application, and are mounted in space-saving racks.
Computer hardware platforms
___________________ include platforms for client computers, dominated by Windows
operating systems, and servers, dominated by the various forms of the UNIX operating
system or Linux. Operating systems are software that manage the resources and activities
of the computer and act as an interface for the user.
Operating system platforms
_________________________ include SAP, Oracle, and PeopleSoft, and
middleware software that are used to link a firm’s existing application systems.
Enterprise and other software applications
_____________________________________ is handled by _________________________________________ include traditional storage methods, such as disk arrays and tape
libraries, and newer network-based storage technologies such as storage area networks
(SANs). SANs connect multiple storage devices on dedicated high-speed networks.
database management software and
storage devices
_________________________________________ include Windows server operating
systems, Novell, Linux, and UNIX. Nearly all LAN and many wide area networks (WANs)
use the TCP/IP standards for networking.
Networking and telecommunications platforms
_____________________ overlap with, and must relate to, the firm’s general networking
infrastructure and hardware and software platforms. Internet-related infrastructure
includes the hardware, software and services to maintain corporate Web sites, intranets,
and extranets, including Web hosting services and Web software application development
tools. A Web hosting service maintains a large Web server, or series of servers, and
provides fee-paying subscribers with space to maintain their Web sites.
Internet platforms
_______________________________________ are relied on for integrating a firm’s legacy
systems with new technology and infrastructure and providing expertise in implementing
new infrastructure along with relevant changes in business processes, training, and
software integration. Legacy systems are generally older transaction processing systems
created for mainframe computers that continue to be used to avoid the high cost of
replacing or redesigning them.
Consulting and system integration services
