Buying a New TV? A Comprehensive Guide to Get the Best Option

These days, buying a new TV can prove to be a daunting task. This is because there are so many options regarding types and features. While doing a quick online search for the best TV options, I was bombarded by more questions than answers. At that moment, I had to figure out whether I wanted a plasma, LCD, LED or an OLED TV. As if this was not enough, an online retailer sang praises about the 4K TV. Indeed, this was even more confusing. Thankfully, this guide has been compiled to give you top pointers when buying a TV in 2018 and beyond. Cut the jargon and figure out the best attributes to consider before making that crucial order for a new TV.

Types of TVs explained

First things first. It is really helpful to learn about the various TV types in the market today. Right now, smart TVs are on top. These are simply those that connect to the Internet. You will be happy to learn that most TVs are now smart. Below is a breakdown of all the major types.

OLED - This is short for Organic Light Emitting Diode TV. They are known for their high quality images owing to their high contrast ratios. They are great if you are looking for that dramatic cinematic experience with your entertainment. They employ LED light to create the images. These screens are known for being pricey. If you do not mind parting with extra cash, this is a good option.

LCD - Liquid Crystal Displays are cheaper than most TVs. Apart from having a good color display, they are excellent at saving energy. However, they are known for their limited angle viewing ability. All in all, they are the most common to find, making them a reasonable bargain.

LED - Short for Light Emitting Diode, these TVs are very similar to the LCD types. The only difference is that here, LEDs are used instead of the liquid crystals. This option does not consume as much power compared to plasma and LCD. The downside is that you will dig deeper into your pocket for them.

Plasma - These TVs will give you high quality dramatic images and displays. They are great if you want a wider viewing angle. They are known for both color quality and a high contrast ratio. If you are looking for that fairly big TV that will serve a sizable room, this is a great choice.

Smart TVs - As hinted to above, these are TVs that give you Internet access for a world of more entertainment. If you are looking to enjoy services like Netflix, these choices are excellent. Some use Ethernet connectors while others use Wi-Fi.

4K TVs - This refers to the resolution ability of the TV. The sharpness is usually measured or determined through pixels. The most common resolutions are HD or high definition TVs. There is a better version of sharpness called full HD. Today, this bar has been set higher as Ultra HD sets give new meaning to TV resolutions. Ultra HD sets are also called 4K TVs.

Top factors to consider when choosing the right TV

All the above types will come with individual specifications. However, there are fundamental elements that should help you decide on the best option as given below:

Screen Size

The size of your room or space should determine the actual screen size. This is because you want to provide the best visuals for everybody present. Also, your budget needs can also determine the screen size. 55 inches are very common if you are looking for that wholesome screen that will suit your area. The larger the screen, the higher the resolution. Therefore, know the specifications to make an informed choice. For budget buyers, anything from 32 inches will serve the purpose.

Refresh rates

With a higher refresh rate, you are able to get a smooth image reducing motion blurs. If you are into action movies or gaming, this high rate will give you that seamless entertainment because the images will remain crisp. Check this rate as indicated in hertz and you will find from 60Hz to 144Hz or more. The higher the rate, the better for you.

Contrast ratio

A low contrast ratio means that the black area of an image may appear as a dull or washed out grey. When it comes to bright areas, there will be lack of vigor and to this end, the ratio must be satisfactory. The bigger the ratio, the better the quality of your images will be.

HDMI and input connections

The plugs and ports will allow you to do more with your TV. To this end, the more the ports, the better for you. From gaming consoles to sound bars, inputs will find many uses. Having at least four HDMI ports is advised. HDCP compatibility is key to 4K TVs shoppers.

General tips for buying a TV online

- Information is always key. When shopping, make sure to get all the information available on the product. Read the specifications provided by the online retailer first. Then, look for reviews that can give you more insights into the functionality and quality.

- Looking for the cheapest TV online may not give you value for money. Know the capabilities of the TV and see whether they fit what you have in mind. Sometimes, spending a little more for a higher quality will save you money in the long term.

GPS - What Is It?

GPS, or Global Positioning System, is the latest thing in keeping from getting lost when trekking out to visit your Aunt Louise. Years ago you had to rely on landmarks, your handy compass or the guy at the corner gas station, assuming he knew where everything was. Today for about a hundred bucks you can get a little gadget that will tell you exactly where you are, any place on Earth. By using some basic mathematical calculations and a rather complex system, you can be in the middle of the desert, lost as can be, push a button and have your GPS tell you exactly where you are so that you can hopefully find your way back home.

So what exactly is GPS and how does it work?

GPS is actually a very complex and expensive system but the fundamental concepts of the system are very simple.

The GPS system is a group of 27 Earth orbiting satellites. Twenty-four of them are in operation and 3 are backups in case one fails. The system was originally created for the US military but was eventually opened up to everyone else.

Each one of these satellites, weighing in at about 4,000 pounds, circles the Earth at about 12,000 miles per hour and makes 2 complete rotations everyday. The orbits are arranged so that at any one point in the day 4 of these satellites are visible from any place on Earth.

The complimenting receiver that was created to receive signals from these satellites has the job of locating 4 or more of these satellites, figure out the distance to each and from that information determine where on the planet the receiver itself is located. It then transmits this location back to the person who happens to be in possession of the receiver. The operation is based on a simple mathematical principal called trilateration. To simply explain how this works, let's say someone tells you that you are 10 miles from Newark, NJ, another person tells you that you are 15 miles from Maplewood, NJ and a third person tells you that you are 20 miles from Woodbridge, NJ. By taking those three facts you can figure out exactly where you are because each radius of each distance when linked together will intersect at only one point. That point is where you are located.

In order to actually do the calculation from space the GPS receiver needs to know 2 things. The location of at least 3 satellites above you and the distance between you and each of those satellites. The reason that only 3 satellites or spheres are needed is because the Earth itself can act as a fourth sphere. The GPS receiver itself works by radio waves which are a kind of electromagnetic energy and travel at the speed of light The receiver can actually figure out how far the signal has travelled by timing how long it took for the signal to arrive from each of the satellites.

In the next article on GPS we'll go over exactly how this system works to measure distance.

Usage of RS 232 in Modern Signalling in Railways

The most popular serial communication standard in use is certainly the EIA / TIA - 232-E specification. This standard which has been developed by electronic industry association and the telecommunication industry association (EIA / TIA) is more popularly referred to simply as RS 232 where RS stands for recommended standard.

RS 232 Specifications

RS 232 is a complete standard. This means that the standard sets out to ensure the compatibility between the host and the peripheral systems by specifying

• Common voltage and the signal levels
• Common Pin wiring configurations
• A minimal amount of control information between the host and the peripheral system

Unlike many standards which simply specify the electrical characteristics of the given interface RS 232, specifies electrical, functional and mechanical characteristics in order to meet the above three criteria. Each of these aspects of RS 232 standard is discussed below.

Electrical Characteristics

The electrical characteristics section of the RS 232 standard includes specifications on the voltage levels, rate of change of signal levels and line impedance. The original RS 232 standard was defined in 1962 as this was before the days of TL logic. It should not be surprising that the standard does not use 5V and ground logic levels. Instead, a high level of driver output is defined as being between -5 and -15 volts. The receiver logic levels were defined to provide a 2V noise margin. As such a high level of the receiver is defined as +3 to +15V and low level is -3 to -15V.

Functional characteristics

Since RS 232 is a complete standard it includes more than just specifications on the electrical characteristics. The second aspect of operation that is covered by the standard concerns the functional characteristics of the interface. These signals are divided into four different categories.

1) Common
2) Data
3) Control
4) Timing

Mechanical Interface characteristics

The third area covered by the RS 232 concerns the mechanical interface. In particular RS 232 specifies a 25 pin connector. This is the minimum connector size that can accommodate all the signals defined in the functional portion of the standard. The connector of the DCE equipment is male for connection housing and female for the connector pins. Likewise, the DTE connector is a female housing with male connection pins. Although RS 232 specifies a 25 position connector, it should be noted that often this connector is not used.

Cheap Calling Cards For Making International Calls

Due to so many scientific discoveries, people have found several ways of living in comfort. When it comes to the field of communications, a numerous inventions can be named. The major communication barrier was making a call overseas. Calling used to be so problematic to many 50 years ago. It is still prevalent in most of the underdeveloped and the developed nations that do not have the advanced technologies.

However, at present the cheap calling cards have been introduced, making the calling process easier. Calling a different country generally costs a lot, even for a very short time of conversation. Therefore, as the number of family and friends of everybody started increasing, so did the need for making cheaper calls. People became more desperate to find a better alternative to the tiresome trunk call booking. As soon as the cheap calling cards were launched, many people started to use them as they put an end to the highly expensive trunk calls.

In those days, people had to spend so much money on making a call abroad. One of the greatest disadvantages in the traditional method of making calls were the fact that the calls could not be made at once and people need to book for a call beforehand and they had to wait for their turn. Distorted voice and vagueness were created because of the interference due to the analog voice signals. In addition, an unacceptable and intolerable time lag used to be a great nuisance to the people as they had to converse in a stunted manner. People found this to be unsatisfactory as they had pay so more for a vague and paused conversation. The duration of the call generally, used to be very less due to the higher rate it costs per minute. Moreover, the operator who controlled the overseas calls always hears the entire conversation and it was never a very secure or a reliable way to talk about private information. These disadvantages were completely eradicated finally from the cheap calling cards.

As the usage of the internet and the mobile phones are at their highest now, similarly, the cheap calling cards have also taken over the conventional landlines. Many people have given reviews saying that they found it absolutely helpful and comfortable to make the calls to whichever country they want. By adding these cheap calling cards to our lives, it is the most wonderful thing to make international calls. Telephones were used earlier, just to bridge up the gap between two persons but not in an economical way as how the cheap calling cards work.

Reaction From The Left to Supreme Court Nominee

Reactions to President Bush's nomination of John G. Roberts to the Supreme Court:

"The president has chosen someone with suitable legal credentials, but that is not the end of our inquiry. The Senate must review Judge Roberts' record to determine if he has a demonstrated commitment to the core American values of freedom, equality and fairness." — Senate minority leader Harry Reid, D-Nev.

"We are extremely disappointed that President Bush has chosen such a divisive nominee for the highest court in the nation, rather than a consensus nominee who would protect individual liberty and uphold Roe v. Wade." — NARAL Pro-Choice America.

"I look forward to the Committee's findings so that I can make an informed decision about whether Judge Roberts is truly a guardian of the rule of law who puts fairness and justice before ideology." — Sen. Hillary Rodham Clinton, D-N.Y.

"The burden is on a nominee to the Supreme Court to prove that he is worthy, not on the Senate to prove he is unworthy." — Sen. Charles Schumer, D-N.Y.

"John Roberts' record raises serious concerns as well as questions about where he stands on crucial legal and constitutional issues. Replacing O'Connor with someone who is not committed to upholding Americans' rights, liberties and legal protections would be a constitutional catastrophe." — Ralph Neas, president of the liberal People for the American Way.

"Without prejudging the nominee, I do believe Judge Roberts' record raises questions about his commitment to the right to privacy, protection of the environment and other important issues." — Sen. Barbara Boxer, D-Calif.

"The president had an opportunity to unite the country with his Supreme Court nomination, to nominate an individual in the image of Justice Sandra Day O'Connor. Instead, by putting forward John Roberts' name, President Bush has chosen a more controversial nominee and guaranteed a more controversial confirmation process." — Sen. Dick Durbin, D-Ill.

"This is a very, very activist court. I want to know whether he's going to be like that, somebody who would eagerly and willingly overturn settled law." — Sen. Patrick Leahy, D-Vt.
