Bitcoins (BTC), also known as digital Bitcoin wallet is a type of cryptocurrency. The majority of the Bitcoin is said to be using a peer network system which regulates Bitcoin transactions and balances. Bitcoins has been referred to as a “peer-to-peer” electronic cash system. The processing of Bitcoin transactions is said to be secured by servers called “bitcoin miners.” The Bitcoin concept is said to be developed in the year 2008 and it was formally introduced in year 2009 by a Japanese developer named Satoshi Nakamoto. The issuance of Bitcoin is said to be of limited release. However, there is a report claiming Bitcoin has no central issuing authority, making it a real concern for people that invest in Bitcoins currency. There were also previous reports suggesting Bitcoin tradings and Bitcoin exchanges have caught the attention of both law enforcements and some regulatory agencies because of the anonymity and suspicious activity that can be associated in the transfer and trading of Bitcoin currency as in money laundering by criminal elements. Furthermore, it has been said that the rate of new Bitcoin creation will be halved every four years until there are twenty-one million Bitcoins in circulation worldwide. Although Bitcoin is promoted as a digital currency of the future, there has been some concern about its volatile exchange rate, relatively low-supply, as well as high risk of loss for people investing on it. Through various exchanges, Bitcoins are said to be bought and sold at a valuable price against the value of other currency. It has been reported that the value of Bitcoin has appreciated rapidly in relation to other major currencies including the British pound, euro and the U.S. dollar. In May 2013, there was a report claiming one Bitcoin traded at around one hundred twenty-five U.S. dollar. Meanwhile, despite the fact that Bitcoin remains an unpredictable investment tool it has also been reported that some employees of international banks and some major financial organizations have shown interest in Bitcoin markets as well. There was a report that the monetary value of Bitcoin as of June 2013 is in the vicinity of around 1.5 billion U.S. dollars. However, there are people who says cryptocurrencies such as Bitcoin is only a scam. Whether Bitcoin loses its steam on popularity or it could become more valuable in the months and years to come is anyone’s guess and remains to be seen.
Apple has introduced on September 10 its latest flagship smartphone, the iPhone 5S. On September 20 it was officially shipped to your nearest apple store. In a nutshell, the iPhone 5S comes with the new iOS 7 operating system, as well as the new Apple A7 system chipset. It also features the new Apple M7 motion co-processor and the new Touch ID fingerprint reader. It has a 4-inch screen with Retina display.

The phone’s rear camera has a dual LED flash, with stills only facial recognition, image stabilization, 10 fps burst mode and slow motion video at 120 fps. It has a multi-touch touchscreen display and a triple microphone configuration. It has a 3-axis gyroscope and a 3-axis accelerometer. The iPhone 5S also has a digital compass, a proximity sensor and ambient light sensor which are pretty typical features of any smartphones out in the market today. As far as connectivity, all versions of this iPhone model has 802.11 a/b/g/n Wi-Fi (802.11n: 2.4 and 5 GHz), Bluetooth 4.0, GPS and GLONASS. The iPhone 5S also feature Apple Maps, Passbook, and iTunes Radio, a free, ad-supported service available to all iTunes users which feature Siri integration on iOS. The iPhone 5S maintains a similar design to the iPhone 5 although its Home button has been updated with a new flat design using a laser-cut sapphire cover surrounded by a metallic ring. The iPhone 5S is available in three color body finishes: space grey, white with silver trim, and white with gold trim. The iPhone 5S can play music, movies, television shows, ebooks, audiobooks, and podcasts and can sort its media library by songs, artists, albums, videos, playlists, genres, composers, podcasts, audiobooks, and compilations. The 5S includes Siri, an intelligent personal assistant and knowledge navigator app which uses a natural language user interface to answer questions, make helpful recommendations, and perform actions by delegating requests to a set of Web services. The iPhone 5S 16 GB sells for $199, 32 GB for $299, and 64 GB for $399, each one with a two-year contract.
Meanwhile, Apple has also introduced the iPhone 5C on the same date as the iPhone 5S. The iPhone 5C was also released on September 20. In a nutshell, the 5C is a low-end smartphone compared to the 5S. This phone uses a polycarbonate casing instead of the metal used by the 5S. Its body casing comes in white, yellow, pink, green, and blue. This phone also uses the new iOS 7 operating system but it uses the Apple A6 chipset. It comes with a choice of a 16 or 32 GB storage. This iPhone model share the same data inputs found on the 5S. It has a 4-inch multi-touch display with 640 x 1,136 pixels resolution at 326 ppi. It has an 8 megapixel iSight camera and 1.2 megapixel FaceTime camera. The 5C can pretty much do the same thing the 5S can do in terms of playing movies, music, and TV shows. It also feature Apple Maps and Passbook. The 5C also has Siri just like the high-end 5S. A dock was also released by Apple for use on the 5C. In the U.S. the 16 GB version sells for $99 and the 32 GB sells for $199, each one with a two-year contract. So which iPhone model is right for you and your budget? In my opinion, both iPhones are okay and your choice would just depend on your own personal tastes and your mobile preference.
Cable and ADSL internet providers have been feuding in an attempt to assert themselves as the industry standard. In an ever expanding market, with so many options for types of internet, let alone providers of internet, it can be difficult to always be ahead of the game in terms of understanding. It is important to always understand fully the concepts which you are comparing before attempting to understand a comparison, to better inform yourself and decide which is the option which suits your needs most thoroughly. Specifically, cable and ADSL can be extraordinarily difficult to differentiate, particularly when viewed solely in terms of the specifications. However, the two technologies are quite different and depending on the needs of the user, one may be a far better fit.
ADSL stands for Asymmetric Digital Subscriber Line, and is a specific type of DSL connection. ADSL functions by permitting larger amounts of information to pass through the copper telephone lines by using particular filters. This also enables ADSL to boast higher speeds and better connectivity than traditional modem lines. ADSL differs from SDSL (Symmetric Digital Subscriber Line) by providing higher download speeds than upload speeds (hence, asymmetric.) In layman’s terms, this allows users to access information more quickly online and costs the provider less in terms of necessary servers. Essentially, ADSL runs using the same technology, and framework, as standard telephones do. The signals are exchanged at a different frequency, as to allow phone calls to be connected even while connected to the internet. Though the speeds boasted are not exceedingly incomprehensible, most users will never flinch at the load times. ADSL is an easy option to implement, as it ports old technology, namely telephone wiring, into a new space.
Cable internet, on the other hand, uses not the existing framework of telephone wiring but of television cable wiring. This may seem to be a trivial difference to some, compared with the DSL networks, however the technological shift provides some major differences. Essentially, the user connects a modem which is linked to another modem from the provider – these filters permit the use of the pre-existing cable framework to connect online. In general, cable internet connections have the capacity to provide far greater speeds, however, with cable internet companies often throttle usage with shared bandwidth. Essentially, the speed of the internet is divided up between a number of residences of a community: the result being that the cable connection is indifferentiable in speed with the ADSL connection.
In the most basic of analyses, ADSL and Cable Internet complete the same job – they will get you online. Typically providers of each tend to bundle their services – DSL internet with phone, and Cable Internet with television. Every company offers different plans, price points and speeds for each individual in their network. The differences in technology do not inherently ensure one to be a better choice in all circumstances, but based on your home needs one will typically rule out. If you use cable service, but not phone service, it could be quite worthwhile to go with the cable internet. If you wish to save some money, and have no need for the added speed, ADSL may be a better option. It is important to understand that each technology exists, and operates in a slightly different manner, in order to make an informed decision when making the choice.
