Here are 10 for you to put into action…if you haven’t already:
If you’re going to travel, remove any CDs, DVDs and thumb drives that might be in your computer, and protect them properly. Also, turn the laptop off—don’t simply put it in sleep or standby mode.
Extreme temperature or temperature swings can have an effect on a laptop. If you’ve just brought your laptop indoors from a very cold day, you shouldn’t turn it on until it has had a chance to warm up and reach room temperature. That might take some time if it’s been freezing outside.
A notebook’s screen is its most fragile and at-risk component, and it can be cracked and damaged easily. Clean it only with approved solutions or monitor wipes. Don’t touch the screen with pens or any pointer that can scratch the surface.
You shouldn’t put a laptop close to appliances that generate a strong magnetic field, such as televisions, large speakers and even some high-tech refrigerators. You should even avoid putting your cellphone on top of your laptop while both are on.
Keep the lid closed as often as you can, which helps to limit the amount of dust that can settle on the keyboard, saves battery life and prevents the keyboard from an accidental coffee spill—a leading cause of laptop damage.
Laptops can overheat more easily than a desktop computer can. You shouldn’t set one on a blanket, pillow or other non-flat surface that could prevent sufficient ventilation.
Be careful where you take your computer and set it down. Again, its portability can work against it. You shouldn’t take it to the beach and risk getting sand in it. Same with using it on the kitchen counter, where it could drop into a sink or onto the floor. And even if it’s NOT plugged in, you shouldn’t finish your spreadsheet while relaxing in the bathtub!
You should always carry it in a good-quality laptop bag or cushiony case that provides protection against drops and jostles. You should also get into the habit of never putting anything on top of it (newspapers, mail), because if it’s on the bottom of a pile, even heavier items—books, backpacks, etc.—could also get piled on.
Set up passwords for access to your laptop (for family members who might also use it). Make sure they do not use “password,” “ABCD” or other simple passwords any thief could guess, in case it’s ever stolen.
Open a personal virtual private network (VPN) account and use it as often as you can in airports, hotels, and hotspots in coffeehouses—in other words, anytime you’re plugged in to free Wi-Fi or strange networks. A VPN reroutes your Internet connection to secure networks, where a hacker cannot steal your data.

Projectors basically provides a cinematic and systematic way of understanding and capturing every moment of slides in our mind’s. These are placed at ceilings at a greater distance for better viewing and clarity. The greater the distance the greater is the image quality. The screens of projectors are made up of plastic or fiber glass some are even metals. Fiberglass are For those who are looking for an increase in quality.
Projectors provide a comfortable and a theatric view at home, Office, Commercial Buildings etc… Projectors are efficient for Presentations because the information’s tends to reach a large number of people at the time of casting.
This type of CCTV surveillance relies predominantly on energy from the sun. Solar panels capture the sunlight, which is then converted into an electrical current that’s used by the camera and rechargeable battery to constantly record and store CCTV footage in a central monitoring system.
There’s absolutely no need for cables or a connection to the power grid. Solar security cameras are wire free and helps in connecting with Wi-Fi – enabling authorized users to view live footage and receive a notification if there’s suspicious activity.
However, it doesn’t matter if there’s no network, or it drops out – the security camera will still record and store footage in the cloud storage. In such cases, all motion is stored on the SD card, though you won’t receive alerts or be able to watch a live stream.
Laser printers can print much faster than inkjet printers. Most are equipped with high-capacity paper trays, so they can print more pages at a given time. They’re also built to handle the printing of thousands of pages per month without succumbing to wear-and-tear.
You should get an inkjet printer if you need to print high-quality color images. Inkjet printers have better tonal variety and they’re better at blending colors. Inkjets can also print on a variety of paper types, including glossy paper. Laser printers can’t print on any paper type that’s sensitive to heat. Inkjet printers don’t print as quickly as laser printers do, and their paper trays can’t hold as much paper. Inkjet cartridges are also more expensive.
More Printing capacity
Black & White
Laser printers can print faster than inkjet printers. It won’t matter much if you print a few pages at a time, but high volume users will notice a huge difference.
Laser printers produce perfect sharp black text. If your print jobs are mostly text with occasional graphics, laser is the way to go. Laser printers also handle small fonts and fine lines far better than inkjet.
Laser printers are better prepared to handle high-volume print jobs.
Price-by-price comparisons favor laser printers over inkjet printers for documents that aren’t graphically complex. Although they’re more expensive, laser toner cartridges print more sheets relative to their cost than inkjet cartridges and are less wasteful.
Although laser printers work faster, they take time to warm-up.
Although toner is cheaper in the long run, upfront costs for laser printing are more.
Toner leaks are a nightmare.
Laser printers can’t handle a variety of paper or printing materials like inkjets. Anything heat-sensitive cannot be run through them.
Home laser printers can handle simple graphics, but smooth photographs are a challenge. If you want to print photos, go for inkjet.
There are some compact laser printers on the market, but in general, laser printers are bigger and heavier than their inkjet counterparts.
High Definition Print’s
High Maintenance Cost
Must Be Used Frequently
Smooth & Colorful
Great for photos and image-heavy documents. Inkjet printers do a better job of blending smooth colors than laser printers.
Inkjet printers have a low start-up cost. Printers are less expensive than laser printers and inkjet ink cartridges are cheaper than toner cartridges.
Inkjets can print onto many types of paper, including glossy photo paper, textured stationery and even some fabrics.
Almost no warm-up time is needed before printing.
Inkjet cartridges can be refilled and reused, cutting down on waste and saving money.
Inkjet printers tend to be smaller, lighter and easier to maintain than laser printers.
Inkjet ink is more expensive than champagne.
Inkjet ink is water-based, so prints are susceptible to water damage and fading.
Ink cartridges need frequent cleaning. Although printers perform this maintenance automatically, it wastes lots of ink.
Inkjet printers are getting faster, but are still very slow compared to laser printing. High volumes are a challenge with inkjets.
Some inkjet printers will produce gray, fuzzy text if printing on plain office paper.
Inkjet printers for home use have low-capacity paper trays of around 50-100 sheets. Output trays are nearly nonexistent. This might be a problem if you print a lot.
