Question 6

principles

Answer 6

*abstraction - dealing with generic form
*bunding - building blocks
*interoperability - platforms are open systems
*evolution - tech is not static, changes through time

Question 7

is the quality of dealing with generic forms rather than specific events, details or
applications. In this respect, abstraction means removing the application of the technology from
the underlying processes and functions that support that application.

Answer 7

abstraction

Question 8

This is achieved by defining a core set of building blocks and then configuring them into different bundles depending on the context.

Answer 8

bunding

Question 9

Platforms are open systems, unlike traditional technologies that are simply designed as
individual physical objects that perform a function,

Answer 9

interoperability

Question 10

tech is not static, changes through time. Adaptive capacity and agility are, and will increasingly be seen as a key requirement,

Answer 10

evolution

Question 11

a critical aspect of platform technologies as it serves as a bridge between different components of a system, allowing them to communicate and interact seamlessly.

Answer 11

interface

Question 12

layer represents the software solutions and services that users interact with to perform specific tasks or functions.

Answer 12

application -

Question 13

is a fundamental component of platform technologies, serving as an intermediary between hardware and software.

Answer 13

operating systems -

Question 14

refers to the underlying hardware and networking components that support the platform and applications.

Answer 14

infrastructure -

Question 15

Protection –

Answer 15

any mechanism for controlling access of processes or users to
resources defined by the OS

Question 16

Security –

Answer 16

defense of the system against internal and external attacks

Question 17

one or more applications available via the
Internet (i.e., word processor)

Answer 17

Software as a Service (SaaS) –

Question 18

software stack ready for application use
via the Internet (i.e., a database server)

Answer 18

Platform as a Service (PaaS) –

Question 19

servers or storage available over
Internet (i.e., storage available for backup use)
