UPDATED QUESTIONS AND ANSWERS
◉Transnational. Answer: a commercial enterprise that operates
substantial facilities, does business in more than one country and
does not consider any particular country its national home.
◉Multinational. Answer: an organization that owns or controls
production of goods or services in one or more countries other than
their home country.
◉Database Management System (DBMS). Answer: Allows multiple
departments to access, analyze, and modify data that is stored in one
central location.
◉Total Cost of Ownership (TCO). Answer: Helps establish feasibility.
◉Platform as a Service (PaaS). Answer: service provider provides
server space, the server, virtualization, operating system, database,
and development environment in a platform that can be used for
application development. An example would be Amazon Web
Services.
,◉Infrastructure as a Service (IaaS). Answer: A service provider
provides a cloud fabric, or pooled services, including server space,
servers, storage, and all other aspects of the computing platform,
with the exception of the operating system and applications, which
the client organization would install and manage.
◉Analytics as a Service (AaaS). Answer: A cloud software service
◉Software as a Service (SaaS). Answer: Software licensed and
hosted on centralized or distributed servers that belong to a service
provider. Users access this software using a connection to the
Internet and a web browser.
◉Agile software development methodology. Answer: an operational
method by which software developers iteratively gather
requirements, plan, design, develop, test, and implement software.
◉Information Technology Infrastructure Library (ITIL). Answer:
common set of best practices widely used by businesses to give
guidance to companies on how to use IT as a tool for implementing
change
◉Pseudocode. Answer: an informal high-level description of the
operating principle of a computer program or other algorithm. Used
for human reading, rather than machine reading, and it can be used
to translate into any programming language.
,◉Input. Answer: components include devices that provide input into
the processing unit. These include peripherals, such as the keyboard,
mouse, microphone (audio input), sensors, and document or visual
scanners.
◉Central Processing Unit (CPU). Answer: the brain/microprocessor
of the computer.
◉Output. Answer: Components include internal storage devices or
processes, as well as external peripherals such as monitor screens
(visual output), speakers (audio output), and printers (physical
output).
◉system bus. Answer: connection between the CPU, memory,
storage, expansion slots, and other motherboard components
◉primary storage. Answer: flash memory chips, such as shown
below, plugged into memory slots on the motherboard.
◉Secondary storage. Answer: accessed only through a system's
input/output bus and is generally several orders of magnitude
slower than primary storage technologies
, Removable media, such as magnetic floppy disks, optical discs (CDs
& DVDs), and USB flash drives
◉Tertiary storage. Answer: consists of an automated robotic
mechanism to mount and dismount magnetic tape or optical discs.
◉First and second-generation computer languages. Answer: were
specific to the computer manufacturer (1GL) or to a specific
processor or environment (2GL).
◉Third generation computer languages (3GLs). Answer: high-level
programming languages such as FORTRAN, COBOL, C, Java, C++, and
C#
◉Java. Answer: An open-standard software language used for client-
server internal applications.
◉COBOL. Answer: The first computer language; developed in the
1950s; still used today.
◉Fourth generation computer languages (4GL). Answer: software
tools that help reduce the amount of procedural knowledge that is
needed about how computers operate and lets end users create
programs as needed; SQL is a 4GL.
