Describe how a user would interact with a smart-phone to do various tasks.Consider inputs and outputs.

Answer 1

A smart-phone is also referred to as a mobile device and it can be defined as a small, portable, programmable-electronic device that is designed and developed for sending (transmission) and receiving data (messages) over a network. Thus, a smart-phone must be designed as a hand-held device with communication capabilities.

Basically, the components that make up a smart-phone can be classified into two (2) main categories and these include:

1. Input: it comprises mouthpiece, keyboard, light sensor, etc.

2. Output: it comprises screen, speaker, earpiece, etc.

In this context, an end user would interact with a smart-phone in the following ways to perform (do) various tasks:

• By using a keyboard to type a text and then sending it to another person.

• By using a mouthpiece as an input for voice (audio) messages when making call.

• The screen of a smart-phone displays the necessary information to an end user.

• When playing a digital music file the speaker produces the output as sound.
