The Effects Of 4G
The Effects Of 4G:
The introduction of 4G will allow everyone to browse the internet of their mobile phones much faster and will diminish "Buffering." However, this was said about 3G when it came out and within quite a short period of time, the amount of time it took for the majority of the population to get it, it became very slow, hence the need for the move to 4G. So basically, 4G will be very good, but we will soon need "5G" or something else that will allow fast browsing.
4G has and will benefit companies and businesses also, because of the huge usage of emails etc that help businesses in contacting their partners and othe businesses.

Voice Over IP (VoIP)
-Voice over IP (VoIP, or voice over Internet
Protocol) commonly refers to the communication protocols, technologies,
methodologies, and transmission techniques involved in the delivery of voice
communications and multimedia sessions over Internet Protocol (IP) networks,
such as the Internet.
-Early providers of voice over IP services offered business models (and technical solutions) that mirrored the architecture of the legacy telephone network. Second generation providers, such as Skype have built closed networks for private user bases, offering the benefit of free calls and convenience, while denying their users the ability to call out to other networks. This has severely limited the ability of users to mix-and-match third-party hardware and software. Third generation providers, such as Google Talk have adopted the concept of Federated VoIP – which is a complete departure from the architecture of the legacy networks. These solutions typically allow arbitrary and dynamic interconnection between any two domains on the Internet whenever a user wishes to place a call.
-VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network as digital audio via an audio stream.
-VoIP is available on many smartphones and Internet devices so that users of portable devices that are not phones, may place calls or send SMS text messages over 3G or Wi-Fi.

There are many different types of computers. Each one has a different primary function, though they all do relatively the same thing.
Computers
-Desktop
-Laptop
-Notebook
-Netbook
-PDA
-Tablet
Desk top computers are primarily used for regular use in one location, such as a desk, hence the name. they have a higher storage capacity than any other type of computer, they can also complete more functions at one time then others but they lack portability.
Laptop. a portable computer that is designed to fit on the lap (although many use them on a desk/table) it does near enough what a desk top does but is compact and light enough to be moved around.
Notebook similar to a laptop but even smaller, it can do many things a laptop and desktop can do except many do not have a dick drive meaning you can’t play cd's or dvd's on the, they also don’t have a high level of storage though this is ever increasing in newer notebooks.
Netbook. a netbook is similar to a notebook in size but does not give the same functions as it is usually used for emails and messaging, there generally cheaper than notebooks but still do not have a dick drive.
PDA. a device that fits into the palm of someone’s hand, it’s used to send email and keep diary’s but not a lot else.
Tablet. a tablet is relatively new invention that usually ranges between the size of and A4 and A5 piece of paper, the have a touch interface and no keyboard this creates a very simple way of using the internet. they are not cheap and lack in a dick drive and do not match the capabilities of any from the above bar the PDA.
Mobile phone in shops.
As a shop assistant myself, I share the frustration of
others on the topic of mobile phones being used when attempting to serve
someone. This is annoying as the people on the phone do not pay attention to the
questions you are asking them and often ignore you. I think many shops would benefit
from a rule or regulation that states that customers on the phone should not be
served until they are off the phone. They
are many problems to serving customers on their phone. These problems follow.
1)
They do not pay attention to the things you are saying/asking.
2)
Other customers often get irritated and annoyed
at them
3)
They take a lot longer to serve this makes the queue
longer and stops people from getting
where they need to be on time thus upsetting others.
4)
As they are not paying attention they often
leave things in the shop such as; credit cards, bags and other personal
belongings.
5)
They also can bump into others and cause a safety
problem as they are not concentrating on where they are going.

Internet usage,
The number of people using the Internet is always increasing, and will always increase.
the problem comes when people want to gain access to the Internet but cant due to there place of living.
different parts of the UK get better or worse coverage of Internet. it comes to pretty much, urban areas receive more coverage then rural areas. this wasn't such a problem 5-10 years ago because not as many people were using it,but the as the Internet population grows the demand for coverage will increase,
there are other problems with using the Internet, especially social networking sites such as 'twitter' or 'facebook' because people can lie about there age and identity. you can imagine the consequences of this problem. also age restricted content especially when using mobile Internet, is becoming an increasing problem as anyone has access to it.
Internet gambling.
If a 14 year old tried to enter a casino they would get refused entry, but on a mobileinternet gambling site, this is simply a box to say yes or no to whether you are 18+. there is no proof of age required. one other problem is that for example if u were in a casino, and had been for a while spending lots of money the casino would probably ask you too leave or advise that u stop, this does not happen when gambling online. as the sites are out top take all your money, even the ones who aren't out to take your money have no way of letting u know you are spending too much money.

Images
when you save an image form the Internet to your computer or mobile device you will have one or two different file options to save it as, for example 'J.PEG' or 'GIF'.
In fact there are many different ways you can save an image, the min difference between all the options is the file size. Often 'J.PEG's are very small, in comparison to a 'bitmap' which are very large.
.bmp)
From a standard view most of the different types of files look very similar if not the same, its when you zoom in that the differences occur.
here are two images. both of these images are of the same thing, exept one is a jpeg and othe other a bitmap, they look idenditcle when put next to eachjother at this level
but if you were too zoom in you would clearly see the difference.
the image file jpeg you be more pixalated as its a smaller image then the bitmap.

How mobile phones work!
your mobile phone is constantly trying to find the closest and best signal.
it does this by sending out radio waves and waiting for a receiving signal, the first radio wave to be received back is in theory the clearest and best signal.
Mobile phone receivers are placed in different location as to try and give u the best signal even when you are on the move!
When you make a call using you mobile phone, a signal goes from you phone to a receiving cell, it then get verified, (this means if you have no credit on your phone, or if you contract has been terminated you will be stopped at this point) assuming your phone has been verified your signal will get transmitted to a 'mtso' (mobile telephone switching office) which will change the direction of your call to the person you are trying to call. this is required for example if the person you are calling is part of a different telephone network to you. the signal then goes to the nearest cell to the person you are trying to call, and then goes form there to there phone.
