D.  What gadgets do you have at your home? How do you take care of them?

Answer:

There are so many gadgets at home. We must take care of them. We have the gadgets such as smartphones, chargers, smartwatches, laptops, earphones and so on.

Due to COVID-19 outbreak, we are gradually realising how our gadgets are the breeding place for so many viruses and germs. Before the lockdown days, every time we touched any object such as handrails, door handles, switches in the elevator, we seldom cleaned our hands leading exposure to various microbes which then transferred to gadgets of our daily use such as smartphones, chargers, smartwatches, laptops, earphones and so on.

Because we work from home and have other gadgets, it's impossible to say how much muck has accumulated between the buttons of our computer mouse or how much hair, dust, and food crumbs have fallen into the cracks of the keyboard. Alternatively, into the wire mesh of the headphones. We may have regular contact with these devices throughout the day, with oil and dead skin from our hands continuously rubbing off on them, making them potential breeding grounds for germs. As a result, keeping our electronics clean and sanitized is more than necessary. Some of the tips to take care of our gadgets are given below:

To keep our gadgets like laptop clean, we can follow these steps:

1.         Step One: Remove your battery, clean it with a microfiber cloth, then blow off the dust using compressed air.

2.         Step two: Using the same towel, wipe down the screen to remove any smudges.

3.         Step three: Spray compressed air between the keyboard's keys and into the USB ports.

4.         Step four: Soak a cotton swab in isopropyl alcohol and gently clean the exterior of the laptop.

5.         Step 5: Wipe down the laptop with a clean, dry cloth.
