Chapter 5: Your Devices—Phone, Tablet, and Computer

Today, most people use three main types of digital devices: a smartphone, a tablet, and a computer. They overlap, but each has a purpose. This chapter explains what they are, why they are different, and how they have changed over time.

1. The Smartphone: Your Pocket Computer and Communication Hub

A smartphone is a mobile phone that also works like a small computer.
It fits in your pocket and is designed for quick, everyday tasks.

Think of a smartphone as:

  • A telephone

  • A camera

  • A map

  • A mini television

  • A messaging and email device

What Smartphones Are Best For

  • Calling and texting

  • Taking photos and videos

  • Checking email quickly

  • Directions and navigation

  • Quick internet searches

  • Short videos, news, and music

How Phones Have Changed

15 years ago:
Phones were mainly for calls and basic texting. Cameras and internet were limited.

Today:
Phones are powerful computers with high-quality cameras, video calls, banking, health apps, and entertainment. Many people use their phone as their primary computer.

2. The Tablet: A Digital Magazine and Living Room Device

A tablet is a larger screen device without a keyboard (unless you add one). It sits between a phone and a computer.

Think of a tablet as:

  • A digital newspaper and magazine

  • A portable television

  • A photo album

  • A simple computer for browsing

What Tablets Are Best For

  • Reading news, books, and email

  • Watching TV and movies

  • Browsing the internet comfortably

  • Video calls with a larger screen

  • Viewing photos and slideshows

Tablets are popular with seniors because the screen is larger and easier to see than a phone, and they are simpler than a computer.

How Tablets Have Changed

15 years ago:
Tablets barely existed or were expensive and limited.

Today:
They are common, affordable, and widely used for reading, entertainment, and casual computing.

3. The Computer: Your Digital Office and Workhorse

A computer (laptop or desktop) is the most powerful and flexible device. It is designed for longer tasks and detailed work.

Think of a computer as:

  • A desk with tools spread out

  • A typewriter, filing cabinet, and calculator combined

  • A home office

What Computers Are Best For

  • Writing documents and emails

  • Managing finances and spreadsheets

  • Storing and organizing files

  • Detailed web browsing

  • Work tasks and complex programs

  • Managing photos and documents

How Computers Have Changed

15 years ago:
Computers were the main way to use the internet. Phones were secondary.

Today:
Many everyday tasks moved to phones and tablets. Computers are still essential for work, organization, and serious tasks.

4. Why These Devices Are Different

Each device was designed for a different role:

  • Phone: Fast, portable, always with you

  • Tablet: Comfortable screen for reading and viewing

  • Computer: Powerful tool for serious tasks and organization

You can think of them like vehicles:

  • Phone = bicycle (quick trips)

  • Tablet = sedan (comfortable travel)

  • Computer = truck (heavy work)

5. How People Use These Devices Today

Today’s typical pattern:

  • Phone for communication, quick checks, photos, and navigation

  • Tablet for reading, entertainment, and casual browsing

  • Computer for finances, documents, work, and detailed tasks

Many people use all three, but you can choose what fits your life.

6. How This Is Different from 10–15 Years Ago

Then:

  • Computers were the main internet device

  • Phones were mainly for calls and basic texting

  • Tablets were rare

Now:

  • Phones are the primary device for many people

  • Tablets are common for reading and entertainment

  • Computers are still important, but more specialized

Technology has moved from the desk to the pocket.

7. What You Actually Need

You do not need every device.

  • Some people only use a smartphone.

  • Some prefer a tablet for home and a phone for calls.

  • Some rely on a computer for everything and use a simple phone.

The right setup is the one that:

  • Feels comfortable

  • Fits your eyesight and dexterity

  • Matches what you want to do

A Simple Guiding Idea

Use the smallest device that is comfortable and the biggest device when you need space and control.

Phones are for quick tasks.
Tablets are for comfortable viewing.
Computers are for serious work.
