Technology plays an important role in our lives. It makes things easier to do through gadgets like tablets, computers, cellphones, pocket WiFi, and modes of transportation. Tablets are portable personal computers that use touchscreens, while computers store and process data. Cellphones use cellular networks to make calls, and pocket WiFi devices allow multiple devices to connect to the internet from anywhere. Technology can be used anytime and anywhere, and has become essential not just for school but also personal use.
