Difference Between 2G and 3G

You may wonder: what's the difference between 2G and 3G? Telecommunication companies certainly aren't overly concerned with helping you to understand. Hence, it's not uncommon for someone to not understand the advantages of 3G over 2G. The aim of this informative article is to clear up that confusion once and for all by clearly explaining the difference between 2G and 3G.

First, a bit of background information. 2G refers to second-generation of cellular wireless telecommunication technologies. 2G is a fairly old standard; the first 2G network was established in Finland in 1991. 

3G, on the other hand refers to the third-generation cellular wireless telecommunication technologies; in the US, 3G refers to the CDMA2000 standard, established in 2002. The difference between 2G and 3G should be becoming apparent at this point - 3G networks possess substantially greater utility than 2G; broadcasting at longer distances, granting more throughput and substantially higher speed.

2G networks are fairly basic in terms of functionality. They're intended to transmit voice data in real-time and not much else. Very lousy codecs are used to encode the voice data, compensating for the relatively low bandwidth of a 2G connection. As a direct result of this, it's hard to hear subtle intonation in someone's voice over a 2G cell phone connection. 2G networks can support other features but they're limited by low bandwidth and slow speeds; features like internet connectivity are typically reduced to slowly loading very basic content; and even with modern Smartphone level hardware, it would be a real pain to try and download large apps. 2G as a standard is largely obsolete in the United States, and realistically you won't be getting a 2G plan unless you have old hardware which you specifically want to use. However, 2G still sees substantial use in developing nations like India due to its much lower cost of operation and use.

3G networks are far more advanced mobile communication networks, featuring download speeds of up to 14.7 Mbps downstream at this point of time with room for improvement in the future. These considerable speeds can be used for advanced features which are either impossible or at least difficult to use on 2G networks. For telephony, a 3G connection's greater speed and bandwidth substantially improves the quality of voice communications. Furthermore, things like full-featured web browsers, streaming video, complex apps, movie and music downloads or real-time upload of photos taken to social media become possible. 

The difference between 2G and 3G should be clear then: 2G is the last-generation standard which doesn't support complex features used in modern cell phone hardware, whereas 3G is a modern standard with broadband-quality speeds that can be used for implementing much more features. 3G isn't even limited to cell phone use- its considerable speed allows 3G connections to be useful in PCs, Gaming Consoles, Tablets or any other portable device which could benefit from a constant internet connection. In contrast, 2G connections aren't any faster than dial-up; their utility is entirely limited to telephony. 3G is a full-fledged mobile broadband system, usable for much more than telephony and it only looks to improve from here.

Facebook now lets you edit comments

We've all done it. Your friend uploads a picture of their new puppy to Facebook, and you somehow manage to leave a comment congratulating them instead on their "new pappy." So what do you do? Until now, the only thing Facebook would let you do to correct the error was delete the comment and start again. But starting Thursday the site is also now offering the ability to edit your comment — and change that pappy back to the puppy you intended in the first place. The edit option appears in the form of a small pencil icon on the right side of your comment. Clicking on the pencil will bring up a drop-down menu with the option to edit your comment as well as the option to delete it entirely. Facebook told Mashable the site will also be "showing the editing history for a comment so that subsequent commenters or likers have the full context of the conversation." That way if someone responds to a comment that gets edited commenters in the future can see the history of the conversation and not get lost. The editing ability went live on Thursday evening, and will be gradually rolling out to all users over the next few days. Has the comment editing system kicked in for you yet? Let us know in the comments.

Man puts himself up for sale on eBay

London: In a desperate attempt to do something instead of cribbing over his likelihood of losing the job within a month, a father in Britain has decided to put himself up for sale on ebay for 20,000 pounds (around $31,000). According to Daily Mail, when Andy Martin was given 30 days' notice that he was being made redundant, the father-of-three decided to take such a drastic action. Having started a blog outlining his new job search efforts, the 45-year-old hit upon the idea of auctioning himself off. Martin, currently a traffic planner for a waste management company, said: "I have been unemployed in the past. "I knew I could either stay bitter and angry, which I was, about losing my job, or I could do something about it. It is a whole new world so I have had to quickly get up to speed," he said. He joined networks. He started using social networking and even bought hits for his blog to point out people to his C.V. "After all of that, I thought, 'why not, I'll put myself up for sale!'," said Martin. With a "buy now" price of 20,000 pounds the Internet site was quick to inform Martin, a former delivery manager, that he was breaching the rules by trying to sell himself. He,however, has been allowed to post the advertisement in the "goods wanted" section. With one interview next week and interest shown by an international confectionery company, Martin, of Stockton, Stockton-on-Tees hopes more and more people will view his CV for consideration. But while hoping that his efforts will pay off, Martin also feels his commitment to work will influence his 11-year-old son in building his future.
