accomplish a task.

Confused?

Read the following article: WHAT IS A SYSTEM?

Make a summary of the following aspects:

1. Definition

2. Characteristics

3. Types

First, some vocabulary

you need to know..

System: a set of things working together as a

mechanism or interconnecting network.

Which of the examples is not a system?

Subsystem: a self-contained system in a larger

system.

Organize the following sub-systems:

Dgisitvee, Bkare, Itnefrcae

A

B

C

Input: what is put in, taken in, or operated on by a

process or system.

Find the input of

the following

examples:

Output: something produced by a person,

machine, or industry; supplied by a device or

system.

What are these outputs?

Feedback: the modification or control of a

process or system because of its results or effects.

**Give feedback to your partners.**

Purpose/Objective: the reason to do something.

What is your

objective for

studying at SENA?

Achievement: Accomplish by effort, skill, or

courage.

What has been your greatest

achievement in life?

ACTIVITY 1.

Fill the blanks with the correct words from the box:

ACTIVITY 1:

UNIVERSAL SYSTEMS MODEL

PURPOSE/OBJECTIVE

What you want

the system to do

INPUT

Resources that go

into the system

PROCESS

Steps that lead to a

result

OUTPUT

The result that comes

out of the system

FEEDBACK

Comparing the results to the objective, the

adjustments are made to the inputs and/or process

So, these are the elements to have a

Universal System Model:
