Socialising on the internet

In the past 15-20 years internet socialising has become very popular for almost all ages of people.  The first of many websites was set up in 1995, the first website was www.classmate.com this website was very popular and you use this website to find old college or school buddies and re contact them to catch up however this was quickly over ridden by friend united which was almost the same and was better in most people’s eyes. 

However in 2004 there was a new website called Facebook and this was a website where you can post what you’re doing upload photos and talk on a website chat and add friends. This was a rapidly growing website and in 3 years there were over 50million people who had obtained a face book account and were mainly used by the younger generation of people with over 85% of people under the age of 22. By 2008 this website had doubled its accounts and had created over 100 million accounts with the median age of 23. In July 2010 there were over 500million accounts made with over 2.15 billion content from users uploaded daily. In 2012 this number had risen to 1billion Facebook accounts which is over 1 seventh of the population and the median age was now 22.

However in 2012 the likes of twitter Skype and Google+ was rapidly growing and was over coming Facebook and Twitter was an easy way to find celebrities and follow them to find out what they are doing where they were quickly had to be verified to have a blue tick next to their name to see who the real person was thanks to the over whelming of parody accounts.

There was also a massive disadvantage of these sites. A woman Found out the death of her child before the police could come and tell her and this was through face book. This was bad and she couldn’t believe that her child died.

There is also the fact that you could find out what happened on T.V shows before it happened through twitter and Facebook. On twitter 26% of people with twitter where using twitter to find out world events, 31% where using it to find out sporting triumphs and browsing what they should watch on T.V before making their own decisions and the other 34% where finding out national news through social networking sites.

If you’re like me and always have your mobile phone on and constantly checking Twitter Facebook and Skype through your phone then this could be distracting for children taking exams and stopping them learning and could overall drop exam passes and could affect the rest of their lives.

Buying a computer system for: a teacher.

 

Researching buying a computer for a school teacher. The first thing a school teacher would need is probably a laptop to take home and use as well as in school because the amount of work teachers do is crazy and emailing work to school over and over again can be tedious. The laptop would have to be reasonably big because teachers tend to do a lot of work & it must also be compatible with hooking up and interactive white board. ADVENT Monza T100 15.6" Laptop – Red would be a good choice for a teacher because, it has certain features like Intel® Celeron® 847 processor, Windows® 8, 6GB ram and a 320GB built in hard drive. The Monza has a 15.3” widescreen which also runs HD and it also has all the required ports to connect up to an interactive whiteboard. There are also a few extra features with the Monza such as they have a new windows 8 operating system. Now because teachers tend to carry laptops around with them this option computer this computer is a lightweight computer which teachers will need if they are moving from class room to class room and from school/college to home. So how much would this cost? Well the total cost for the computer with the charger ect. Is £299 which is very cheap compared to a laptop like SAMSUNG Series 9 NP900X3C 13.3" Ultra book™ which cost well in Assess of a grand so this does seem like a fitting type of laptop for teachers. Now if you’re an older teacher And are not as up to date on technology as some of the younger teachers then getting a laptop probably isn’t the correct option for you because, you may already have an older slower not as good computer at home and could be perfectly fine with sending emails to and from home all the time but not if you have as much patience as me. So if you’re up to date with technology and you want a decent not too expensive laptop computer that is cheapish then this would be the perfect choice for most teachers, of course you’re going to have to buy a laptop case with this but then again it’s worth it because you wouldn’t want to waste 300 odd quid.

What Affect Will 4G have On The World

 

4G is the next generation of mobile communication standards, picking up where 3G drops off and delivering higher download and upload speeds. In other countries, such as the US, different technologies — such as WiMax — have been deployed to provide higher-capacity data services. In the UK, WiMax is very rare, with just a few small operators serving specific towns or cities. So in the UK, at least, the future of 4G is LTE. And LTE, like every other data communication standard, operates in a specific frequency or set of frequencies. But to add to the complexity, the UK's LTE services operate in a different band to those in the US, meaning that certain 4G-equipped devices won't work everywhere in the world.

You can think of the issue with different 4G bands in a similar way to how you used to have to check whether a phone was dual, tri or quad-band to see if it would work abroad. In the UK, LTE services will use the 800MHz, 900MHz, 1800MHz and 2.6GHz bands whereas the new iPad, for example, will only work on 4G networks that use the 700MHz or 2.1GHz frequency bands. So if you're on a trip to the US anytime soon and are considering snapping up a new 4G-equipped phone or tablet, be aware that it almost certainly won't be compatible with the UK's 4G networks.

Have you ever been out and about trying to watch a video on YouTube or stream some music and have it steadfastly refuse to playback without constant buffering? Yes? Well, that will be a thing of the past with 4G. Of course, that was the promise of 3G but it never quite seemed to be the case. Where 3G HSPA+ speeds are currently maxing out at around a theoretical 42Mbps downstream limit, 4G promises to deliver up to 100Mbps for users on the move. But it's not just for urban hipsters — 4G could also play a role in bridging the rural broadband divide in the UK.

Types of different images and what they are

JPEG: In computing, JPEG is a commonly used method of lossy compression for photographic images. The degree of compression can be adjusted, allowing a selectable trade-off between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.

GIF: The Graphics Interchange Format (GIF) is a bitmap image format that was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability

Bitmap: an image represented as a two dimensional array of brightness values for pixels.

TIFF: Tagged Image File Format (abbreviated TIFF) is a file format for storing images, popular among Apple Macintosh owners, graphic artists, the publishing industry, and both amateur and professional photographers in general. As of 2009, it is under the control of Adobe Systems.

PNG: Portable Network Graphics (PNG) is a bitmapped image format that employs lossless data compression. PNG was created to improve upon and replace GIF (Graphics Interchange Format) as an image-file format not requiring a patent license.

How Mobile Phones Work

Mobile phones work by switching between 2 different types of signal: radio and telephone. Mobile phones work in 2 ways one way is sending an electromagnetic microwave from your phone to the base station and back again this is what gives us signal the other way is the waves are sent to antennas to a base station and back again ton your mobile phone As you talk on your phone, it converts your voice into an electrical signal, which is then transmitted as radio waves and converted back into sound by the phone on the other end.

 A basic mobile phone is therefore little more than a combined radio transmitter and a radio receiver, quite similar to a walkie-talkie or CB radio. In order to remain portable, they need to have compact antennas and use a small amount of power. This means that mobile phones can send a signal over a very short range.The cellular network enables you talk to your friends, however far away they are. This is done by dividing up land into hexagonal areas of land, each equipped with their own phone mast (base station.)These massive phone masts pick up the weak signal from your phone and relay it onwards to another phone mast nearer to your friend on the other line. And if you’re on the move while you talk, your phone switches masts as you go without interrupting your call

http://www.orange.co.uk/
http://www.three.co.uk/) these are the cheapest possible prices as of 10/10/12 (cannot tell the prices of the future)

 

what I did I found all the data in there differant websites from differant places and made notes of the cheapest possible prices of the differant selections of the iphone5. I have also included the full amount you have to pay yearly and the amount you have to pay daily. I have also included the contract legnth and the amount you have to pay upfront for each phone. Next I used the printscreen tool and put this picture into paint, after this I cropped it down to size write this not the added the picture to this document by using the insert picture tool inbetween the insert link button and insert mp4 (movie) button.
