MODULE 1 Flashcards
(36 cards)
It is derived from the Greek word Systema, which means an
organized relationship between any set of components to achieve some common
cause or objective.
System
It implies structure and order. It is the arrangement of
components that helps to achieve predetermined objectives.
Organization
It is defined by the manner in which the components operate with each other
Interaction
It depend on one
another. For proper functioning, the components are coordinated and linked
together according to a specified plan. The output of one subsystem is required
by other subsystems as input.
Interdependence
It is concerned with how system components are connected together.
It means that the parts of the system work together within the system even if
each part performs a unique function.
Integration
The objective of the system must be central. It may be real or stated. It is not
uncommon for an organization to state an objective and operate to achieve
another.
Central Objective
It is the element of a system that involves the actual
transformation of input into an output.
It is the operational component of a system.
It may modify the
input either totally or partially, depending on the output specification.
Processor
It guides the system.
It is the decision–making subsystem that controls the pattern of activities
governing input, processing, and output.
Control
It is the “supersystem” within which an organization
operates.
It is the source of external elements that strike on the system.
It determines how a system must function. For example, vendors and
competitors of the organization’s environment may provide constraints
that affect the actual performance of the business.
Environment
Are the limits
that identify its components, processes, and interrelationship when it
interfaces with another system
Boundaries
Tangible entities that we can feel and touch. These
may be static or dynamic in nature, for example, take a computer center.
Physical Systems
Are conceptual. These are not
physical entities. They may be formulas, representations, or models of a real
system
Abstract Systems
The main purpose of information systems is to manage data for a
particular organization. Maintaining files, producing information and reports are
a few functions. An information system produces customized information
depending upon the needs of the organization.
Man Maid Information System
Are computerized information
systems that were developed to process large amounts of data for routine
business transactions such as payroll and inventory.
Transaction Processing Systems
It support data workers, who do not usually create new
knowledge but rather analyze information to transform data or manipulate it in
some way before sharing it with, or formally disseminating it throughout, the
organization and, sometimes, beyond.
Office Automation Systems
It support professional workers such as
scientists, engineers, and doctors by aiding them in their efforts to create new
knowledge (often in teams) and by allowing them to contribute it to their
organization or to society at large.
Knowledge Work Systems
A higher-level class of computerized information ssystems.Is similar to the traditional management
information system because they both depend on a database as a source of data.
It departs from the traditional management information
system because it emphasizes the support of decision making in all its phases,
although the actual decision is still the exclusive province of the decision-maker.
Decision Support Systems
Are used in special rooms equipped in a number
of different configurations, permit group members to interact with electronic
support – often in the form of specialized software – and special group facilitator.
Group Decision Support Systems
It help executives organize their interactions with the external environment by
providing graphics and communications technologies in accessible places such
as boardrooms or personal corporate offices
Executive Support Systems
Its role is to straddle the divide between identifying
business needs and imagining a new or redesigned computer-based system to
fulfill those needs.
System Analyst
Programmers spend their time writing computer code in a programming
language. They are proficient in
mathematics, as mathematical concepts underlie most programming code.
Programmer
Design the computing devices that we use every day.
There are many types of computer engineers, who work on a variety of different
types of devices and systems.
Computer Engineer
Designs hardware
components, such as microprocessors. Many times, a hardware
engineer is at the cutting edge of computing technology, creating
something brand new.
Hardware Engineer
They do not actually design
devices; instead, they create new programming languages and operating systems, working at the lowest levels of the hardware to
develop new kinds of software to run on the hardware.
Software Engineer
