The Most Important Types of Mobile Devices

Mobile devices and the Internet, especially Wi-Fi technology, have made interaction with people around the world possible. The use of these devices has now become commonplace that it would be hard to imagine the 21st century without the existence of these technological marvels. Check out this guide to familiarize yourself with three common portable devices.

Rugged Computer

A rugged computer can work well even if it is used in extreme weather conditions such as sandstorms and blizzards. Some are also immune to shock damage. This makes it a valuable tool for field workers. For example, rugged devices, such as tablets and smartphones, are used by companies in the public safety industry. Their durability has endeared them to transportation and warehouse management companies as well.

First responders and other field workers need gadgets that can keep sensitive information safe and survive the pressure of inhospitable environments at the same time. They prefer to use rugged devices, such as Zebra devices, because they are designed to withstand rough handling. This can dramatically reduce the need for Zebra repairs, for instance, and lessen the need to replace damaged equipment.

Digital Camera

Sometimes it also lacks a viewfinder, whose function is replaced by the liquid crystal display (LCD). With the analogue camera, the number of shots you can take was limited by the amount of film you have. The arrival of digital cameras allowed people to snap photos to their heart’s content.

In 1991, the Eastman Kodak Company (Kodak for short) launched Nikon F-3, the first professional digital camera. It had a 1.3-megapixel sensor. But digital photography was only fully embraced by photojournalists in the late 2000s. In 2001, film cameras were still widely used for news reports. For instance, a lot of photos in the news coverage of the September 11 attacks have been taken with analogue cameras. But media organizations gradually switched to a digital workflow process because digital images could be edited and sent much faster.


This one is a wearable computer that looks like a wristwatch. Aside from telling time, most smartwatches have a fitness tracking feature. It can count the steps and the distance you have traveled. Aside from this, it can also monitor your pulse and heart rates. If swimming is your chosen form of exercise, waterproof wrist-worn devices are also available.

You can make and receive messages with this device. Some smartwatches have a voice support feature, so you will be able to take and make calls as well. This feature can be extremely helpful for active people such as marathoners and mountaineers, especially if they encounter an accident. If ever you are injured and find it hard to use or reach your cell phone, you can use the smartwatch to call for help.

The technological landscape has undergone various transformations since the arrival of early computers, but it can be helpful to look back on the early forms of handheld devices. After all, the invention of the prototypes paved the way for the development of the versatile gadgets that we use today.
