*^PORTABLE+DEVICES!

Introduction

In our modern-day world, technology has changed how we live every day. Most importantly how portable devices have been used for example laptops are a good way to bring your computer on the go or bring it anywhere, cell phone help us with communication, and GPS's help us with navigation to various places

Laptops

Laptops affect our lives because you can take them anywhere. It helps especially students a lot because with a laptop they can work at home, in the library, or in class (1) important aspect of laptops and computers is that people can bank online, shop online, buy/sell online, work online and earn online too. So, this invention has revolutionized our economy in a positive way

When comparing them to PCs(personal computers), they are way more efficient. Laptops consume up to 80 percent less electricity than desktop computers and get by on between one-fifth and one-third as much energy. Laptops benefit in the energy efficiency and consumption areas even when plugged into an electric socket because of battery-powered design.(2)

The most powerful laptops today are capable of handling incredible workloads. In the past, for tasks like video editing or graphic design that required a lot of high-performance hardware, no laptop would have been able to come close to the capabilities of a desktop (3). Even the screens of these portable devices can have the ability to have high-DPI colour accurate displays that look amazing, such as the DCI-P3 Retina display by Apple or the 4k screens on some windows laptops.

Cellphones

Cellular devices are essential for many people worldwide. They give us the ability to keep in touch with family, business associates, and business connections. Today's technically advanced cell phones are capable of not only receiving and placing phone calls, but storing data, taking pictures, and can even be used as walkie talkies (4)

Using phones also have impacts. According to the Using phones also has an impact. According to The World Health Organization (WHO) classifies cell phone radiation as a "possible human carcinogen" due to an increased risk of brain cancer from long-term and heavy use of cell phones. Although short-term cell phone exposure has not been shown to cause brain tumours, research is showing that it can change your brain activity in ways we don't fully understand yet.(5)

GPS

The Gps or Global Positioning System is very indispensable to people's lives. The GPS is a network of orbiting satellites in space that sends precise and accurate positions. GPS has the ability to pinpoint locations up to three dimensions like latitude, longitude, and altitude. The signals from a GPS can give accurate and concise information that is used to estimate speed, time, and exact location of objects or humans. GPS has been freely available to companies, countries, organizations and to anyone with a GPS receiver. Airlines, trucking companies, shipping companies, and car owners all use GPS systems to monitor and track the location of flights, trucks, vessels, and cars. The navigation route can be monitored in the shortest time possible and as accurately as possible (6).

GPS can also give directions to people who are clueless of where they are headed. Some navigational systems are located in cell phones which are very important for people, for example, uber drivers and taxi drivers use it to get to their customer's waypoint. Modern cameras have the ability to tag a location, and time automatically to digital images such as photographs. A camera such as Nikon GP-1 uses GPS data to create map overlays by adding location coordinates to documents and digital images.

In conclusion, In our everyday lives it is essential to have these portable devices. The laptop is a good portable computer, the cellphone is a good way to keep connected to the world, and the GPS is a modern day navigation system.
