How 1600 x 1600 pixels in inches?

There is no way to give a real answer for that. Pixels do not have a consistent size, so they can't be universally converted. Pixels change size depending on the density of the thing displaying them (72 dots per inch is typical for screens and 300 dpi is typically selected for something that will be printed as form of Quality Photo). For screens size differs based on "Pitch" of the screen(distance between two consecutive pixels) thus even small screens with low pitch value can display high resolutions!

Is media spoiling your young generation or not?

"Media" is a term that covers a vast array of information storage and delivery. It includes newspapers, magazines, books, radio, television, computer based storage and retrieval.

Do newspapers spoil our young generation? Probably not. And on line news services are also not considered to be harmful to young people. No doubt, content is available that delivers poor moral messages to people, young and old. Content on social media sites is often of such a poor quality that it is barely understandable and of no value at all.

It is far too general to arrive at an answer to the question. Some media are very good for children and teenagers, others are just the opposite. However, to blame a medium for harming a generation is simplistic and probably incorrect. Look to content carried by the medium to judge it, not the medium itself.

How has technology influenced the arts in the last century?

Art has been known to man right from the very beginning as evidenced by the relics of the past. But certainly, technology has made it possible for new equipments to be taken advantage of and for new mediums to be used. There is also the option of digital art that will allow people to work with colors and images even without the most intensive training to create the best masterpieces.

Many technological changes occurred during the Modernist period. These included photography, the invention of the color spectrum, etc. In the postmodern era, changes included computer-manipulated photography, digital media, etc.

Many artists portrayed subject matter influenced conceptually by technology as well. For example, the futurists, who idealized the beauty and potentials of technology, but many artists also explored the negative effects, e.g. Patricia Picnicking - "Restless".

Things like photography have made art easier than in the past. We now have a different variety in colors that can make our photos stand out.

Other improvements have been the convenience of measured gradients of paints. In the old days the artist would have to make their own paints; processing such things would be time consuming and hard to reproduce. Also technology has allowed us to make things like bridges, buildings, and new ways to do it with engineering. This has allowed for a spur in the art community, opening doors to various ways to express the artist's feelings.

Technology has also completely redirected many forms of art. For example, there is much more reliance on graphic design in art and new techniques in film making today than there used to be. Graphic design tools are used for advertising and marketing, but can also be used to edit other art forms, such as photography or film.

How did early computer security work?

When I hear the word "early computer security, all I can think of are human security men with guns, trying to protect the first huge computer from thieves trying to steal it. At that time, I don't think they were worrying about viruses as compare to real people stealing the computer which can take up to 6 people to carry. Then, I think people were the Virus you'll need protection from.

How do science and technology help daily life?

What are the disadvantages of ecommerce for customers?

Everything has some advantages and some disadvantages. Here as well there are some (actually a lot) advantages and some disadvantages.

Some of the Disadvantages that I'd and some people had suffered are

  1. Payment Bouncing
  2. Late Deliveries
  3. Something else delivered
  4. Product Quality Issues
  5. etc.

But, according to the situation of Covid and preferences of most of the people I think there are huge number of advantages of eCommerce if we compared it with its disadvantages.

What is the proper way to connect an ammeter?

Originally Answered: How should an ammeter be connected in a circuit to correctly read the current?

Let’s consider DC based circuits first. Ammeters then are connected in series (like in a sequential chain) between the power supply or source (not necessarily the same) and the power drain (or the circuit load). Since we are talking about a DC circuit, the power to the circuit is first turn OFF to prevent sparking (in a large current situation) and to allow the measurement driven modification to be made. I usually measure if any voltage is present at the power leads where the current measurement will be done. The reason for this is to see if there are any sneak power circuits feeding the circuit under test. The circuit is then broken (or opened with either a switch, a jumper plug removal or simply disconnected) on the (usually) positive side of the supply. If you have to physically cut the positive feed wire, make sure that you can reconnect it so that no short exposed wires remain after the measurement.

Make sure that you use an ammeter that will be able to appropriately measure the load. As an example if you are trying to measure a current with a supply current in the range of 7.5A, connecting an ammeter that is designed to measure 0 to 1A, then the instrument will most likely burn out. Professionals use ammeters that have switched multiple current range or are using measuring meters that can be shunted with the appropriate range shunt. The meter positive connection (usually a red wire or probe) is connected to the positive source of the power supply. The negative wire or probe (usually a black wire) is connected to the power load (where the circuit was cut/interrupted or disconnected previously.

Assuring that everything is done properly, then depending on the meter used turn the power supply on again. As a note if you are using a digital multi-meter, the instrument should be turned on FIRST, perhaps set on the highest current range. Turn the power supply back on and observe the current indication on the meter.

As mentioned by other fellow Quorians, if using a current probe, then it is easier but less flexible. For AC based circuits, there are no polarities to worry about but the range issue has to be factored in. The rest is more or less the same procedure.

I have been doing electronics, measurements plus remote customer support to solve power supplies issues over the phone for many years and I have seen (and experienced) my share of mishaps, errors, absence of knowledge/hands-on experience. I have seen accidents (some life threatening) so I am sharing a thing or two to help

How do you fix a broken DVD?

You can use wax and polish and sometimes glue and tape to repair a scratched or broken DVD. Deep scratches may not be repairable, and may require professional help.
