People were vying to beat each other and so, as an improvement on dual cores, the latest smartphones started coming out with quad core processors. However, today, with people obsessed with more power and speed, even quad core doesn’t seem to be enough, as several brands are competing with each other to release octa core powered handsets. So, while the battle of the cores seems to be never ending, users are confused. Is an octa core device really better than a quad core one? How can one decide on which device to put his money?

The answer isn’t as obvious as one may think because as several smartphone reviews will tell you, more isn’t always better. Going by the plain math that is visible, users may feel that an octa core processor is bound to better than, or maybe even twice as good as a quad core processor. It is high time that this myth needs to be debunked. A quad core chipset has four cores, where in case of heavy activities like HD movie streaming, all four cores can be activated and can jump into action so that your user experience isn’t interrupted. However, when it comes to an octa core chipset, are basically a dual set of quad core processors, where each set is assigned toward fulfilling a special task, so that unless that task takes place, four cores are not in action. Hence, when more heavy lifting is required, only then will your second set of quad core muscle come into play.

In essence, octa cores may not be faster than quad cores all the time but due to the efficient spacing out of the device’s workings, they end up being more efficient. One fact that several people do not know that a better and more efficient processor and chipset will help to prolong the battery life, a complain that is rampant among many of the latest smartphones. Hence, as smartphone makers are working day in and day out to help come up with a device that is efficient in its power consumption, while also aiding in prolonging battery life, octa core answers the million dollar questions by offering a solution to both these major problems of speed and battery life.

Nowadays, purely for the sake of achieving more efficiency, several companies are working hard to produce chipsets that are specifically ‘optimised’ for the handset they sell. For example, Samsung came up with its own Exynos chipset, which may not have been anything new in terms of design or features but it was specially designed for its own handset, so that it worked better and smoother. Thus, the answer doesn’t always lie in cores but as smartphone reviews will tell you, more so lies in the optimisation and personalisation of processors and chipsets for specific handsets.

Radio Frequency is Over 100 Years Old

While it may seem hard to believe, radio signal technology has been around for over a century now. By the time the Twentieth Century had started, Alexander Popov and Sir Oliver Lodge, two budding electrical engineers, were paving the way for radio. In December 1901, Guglielmo Marconi had developed a wireless transmitter and receiver. He used these tools in a famous experiment where he successfully transmitted a morse code message through radio signal from Cornwall, England, to St. John’s, Canada.

What is RF?

Today, radio frequency is so synonymous with wireless signals that the terms are used almost interchangeably, with radio frequencies describing everything from AM bands between 535 to 1605 kHz to Local Area Networks that top out at about 2.4 GHz. Traditionally, however frequencies defined as radio signals only ranged from a few kHz to roughly 1 GHz. Although, if you include microwave frequencies in radio, this range could be extended all the way to 300 GHz.

Different Frequencies are Used for Different Applications

In modern times, the use of radio is highly regulated and controlled. So much so, that specific frequencies of radio signals are used for very specific applications. For instance distress signals or telegraphs are set to only be on frequencies between 490 and 510 kHz.

Different frequencies are used for police scanners, amateur radio, cellular phones, global positioning systems or GPS, LANs and wireless internet, and even microwave ovens. The most basic and necessary applications usually are conducted on the lower frequencies, whereas more private and specific applications will occur on very high frequencies.

Why Operate on a Higher Frequency?

As you know, the frequency spectrum is fragmented and dense with allocated uses for each specific frequency. This is one of the reasons that applications keep being pushed into higher and higher radio frequencies. As new applications are discovered or intended, higher frequencies are used to accommodate them. Each frequency has different advantage and disadvantages regarding signal strength and propagation efficiency as well as interference and noise.

Frequency Shifting and Mixing

Often special technologies are need to receive and make sense of radio signals. For instance, the human voice exists on one particular radio frequency, however cellular phones operate on a different one. In order to make the human voice sound natural and normal through a cellular phone, the voice signal needs to be mixed or shifted in order to match the frequency that the phone operates on. Typically, a device called an RF downconverter is used to shift frequencies so they can be received and made sense of by radio technicians.

The first benefit you are going to find when it comes to choosing promotional memory sticks is that you enjoy improved brand visibility. As your customers make use of the memory stick in their daily work and home lives, your name is there on display.

Remember every time someone uses your memory stick showcasing your company name and logo, they think of your company. This means when they need a product or service that you provide, you will be the first call they make.

While promotional memory sticks may be brimming with so many great benefits, there are some important factors you are going to want to take into consideration. The first and foremost consideration to factor into your decision is your target audience. Ensure any product you choose will meet the daily needs of your customers. If the majority of your customers use mobile devices and store vast amounts of data, then this is the ideal choice to ensure your name is on the tip of their tongue at all times.

In addition to this, you will want to ensure the products you purchase are of the highest quality, this will ensure your company is seen in a positive and professional light at all times. They should come with a good warranty, putting your mind at ease that you are buying a good quality product that will provide your customers with years of use and convenience moving forward.

Firstly, it is important to remember that although there is a huge range of vendors operating online nowadays, they certainly are not all made equal. It is in fact one of the main gripes of any shopper in any market that the online retailer that was claiming to have the best products at the best prices actually turns out to be a major disappointment.

The reason for this is that anyone can easily become a seller of products that they do not really know much about on eBay or other public auction sites, making it hard to distinguish the pros from the amateurs. Our first tip, therefore, is to seek out a seller that has a certain level of expertise in the area they are dealing in.

This is crucial for a number of reasons, the first one being that – assuming they are reputable and take pride in the standard of products they offer – you are very unlikely to come away with a product that does not meet your criteria or perform well. Good retailers will tend to know which products are good ones and which are not so good, and steer clear of selling the latter to their customers.

With that in mind, look for a specialist in SSD disk drives or SCSI drives if you are looking for these products, rather than just shopping around for the cheapest price. The other major advantage of buying from a specialist is that they will often be able to provide excellent expert advice before you buy, saving you from investing in the wrong product.

The next thing to note is that it is important to choose a company that has a good returns and refund policy, as this can save you a headache farther down the road if you run into any problems. Although the item might be great quality, some will always turn out to be faulty, and this is where a good return and refund policy will help you.

Before you purchase your SSD disk drive, therefore, do adequate research into how things work if you are dissatisfied with your product, and look for negative customer reviews of a company before purchasing. It is when things go wrong that a retailer shows how reputable he is, so if a company has a track record of reluctant refunds, it is possibly better to choose someone else.

On top of these few points, make sure that you get a good price for the item you are buying. It is often hard to know what is a cheap price for the SSD disk drive you are after or what is an expensive price, so shop around to see what offers are available for that particular item.

If you see your product at a particularly low price compared to all the others, exercise caution – huge price drops can indicate that the item is defective or second hand, or that simply you are dealing with a less reputable dealer of a product. In all cases, take the time to read the small print before you buy, and you are likely to find yourself with a great product at an excellent price.
