The world we live in has become so reliant on technology, that it becomes difficult to operate without it. This lesson will walk you through some of the devices we use daily and the occupations that rely on them.

We Live In a Connected World

Technology plays a much more significant role in today's society than ever before. Whether it is for personal use at home or business use at our place of employment, we rely on our electronic devices to keep us connected to the rest of the world. Some of the devices we use on a daily basis are smartphones, tablets, and laptops. All three of these devices are portable, which allows us to deal with our personal and work lives from anywhere in the world. Each device serves a purpose for specific occupations, and we will dive into some of those examples below.

The massive smartphone craze has taken over the world thanks to companies like Apple and Google. Since smartphones are such popular devices today, a lot of new possibilities are opened up for getting work done like never before.

Tablets and Laptop Computers Have Their Place

Some example occupations that use laptop or desktop computers are as follows:

  • Retail Employees - Whenever we get to the register to make a purchase, we can see an overview of our transaction on a monitor. Many of these registers are built around the Windows ecosystem and rely solely on laptop or desktop computer hardware.
  • Health Care Professionals - Medical staff, usually store their customer database and other records on computer systems. They interact with and rely on their desktop and laptop computers so heavily that they become a necessity for daily operations.
  • Financial Managers - Banks, in particular, are known for needing laptops or desktops to serve their customers adequately. Customer accounts and information are all stored in databases, safely hosted on secured servers and are accessed only through these kinds of devices.
