Difference between 4G and 3 G technology

On the surface, the difference between 3G and 4G is pretty simple. The “G” is short for generation, so 3G and 4G represent the third and fourth generations of mobile broadband Internet. As a rule, provided that you’re on the same carrier, a 4G connection will be faster than a 3G one. However, that doesn’t necessarily mean that a 4G network of one carrier will always be faster than the 3G network of another.

To be advertised as 3G, a network is required to meet a set of technical standards for speed and reliability, and must offer peak data transfer rates of at least 200 kilobits per second.

To be advertised as 4G, a network must offer peak data rates of at least 100 megabits per second for high mobility communication (users in cars, trains, etc.), and at least 1 Gigabit per second for low mobility communication (pedestrians and stationary users). On the surface, the difference between 3G and 4G is pretty simple. The “G” is short for generation, so 3G and 4G represent the third and fourth generations of mobile broadband Internet. As a rule, provided that you’re on the same carrier, a 4G connection will be faster than a 3G one. However, that doesn’t necessarily mean that a 4G network of one carrier will always be faster than the 3G network of another.

It’s also worth noting that each new generation of wireless broadband typically requires your cell phone provider to make upgrades on their towers, and therefore requires you to upgrade your phone so that it can send/receive signals through the new infrastructure. A 3G phone cannot communicate through a 4G network, but newer generations of phones are practically always designed to be backward compatible, so a 4G phone can communicate through a 3G or even 2G network.

When to go with 3G

• You might want to skip the 4G route and opt for a 3G phone if:
• Your area doesn’t have 4G network coverage.
• You don’t really use a lot of data-hungry applications.

social networking will work just fine on a 3G connection.

When to go with 4G

You might want to consider getting a 4G phone if:

• You want a newer model cell phone. 4G networks are becoming pretty standard, so most of the newest and most cutting-edge phones (Samsung Galaxy S3, iPhone 5, etc) are typically 4G phones.
• Your carrier has a solid 4g network in your area. If its there, you might as well take advantage of it.
• You use lots of data, and could benefit from faster speeds. If you like to watch YouTube on your way to work, stream Spotify everywhere you go, and you rely on a boatload of internet-connected applications to make it through the day, then go with a 4G connection. Having blazing-fast internet in your pocket at all times is useful, and data plans usually cost the same amount regardless of whether they’re on 3G or 4G.

3G presently is the world’s best connection method when it comes to mobile Internet. 3G is the abbreviation for third generation. It offers the download speed up to 3.1 Mbps (Mega bytes per second). but now there are so many varieties of 3G that now anywhere one can get an Internet speed of more than 400Kbps.

4G mobile networks are supposed to provide many value added features. When 4G will be connected to smartphones, tablets or computers, it can handle more data than 3G. A 4G system offers mobile ultra-broadband Internet access. For example: to laptops with USB wireless modems, smartphones and to other mobile devices. LTE is what most are calling 4G, but in reality it is just an advanced 3G standard that some call 3.9G. It uses a completely different radio technology. Although in many countries around the world, 4G is not yet released but definitely will get released very soon.

It’s very upsetting to get abusive emails, instant messages and to have nasty websites or social network profiles set up to invite people to post offensive remarks about you. This is called cyber bullying.

Affects of Cyber Bullying:

Cyber bullying affects people from any age or walk of life, including children, teens and adults who all feel very distressed and alone when being bullied online.  Cyber bullying can make you feel totally overwhelmed which can result in many feeling embarrassed that they are going through such a devastating time, and not knowing what support is available to them.  Many children feel unable to confide in an adult because they feel ashamed and wonder whether they will be judged, told to ignore it or close their account which they might not want to do.  Cyber Bullying might demotivate a certain personality. 

Ways to stay safe from Cyber Bullying:

Parents should always supervise their children while the are using the internet. Children should also be aware that they are not to get in contact with any strangers that they find on the internet.

Even if the people posting this abuse do so using a false name, they can still be traced because the firm which hosts the website will keep logs which detail where uploads have been made from. You and your parents can’t access this information but the police can.

If you’re getting rude comments by instant messenger print them out and give them to your parents. They could contact the police if the messages are threatening or if there are so many of them that they could be considered to be harassment.

Dignity Day is an initiative to educate and inspire young people and help them to understand their self-worth and goals.Dignity day is celebrated all over the world to represent our gratitude and respect to each other.Dignity is deserved by each and everyone and this day spreads awareness of the importance of dignity in our life.

Dignity day is celebrated in schools including our school.The students of Beacon House Liberty Campus had a great opportunity to participate in various activities related to dignity day. They sang songs, made dignity posters, wrote poems and gave gifts to our staff members. The students even performed a special morning assembly just for this special occasion.

Except for schools everybody celebrates this day. We all can make a big difference by spreading awareness of Dignity. Dignity is a word that gives justice to all the members of our world. And justice is to be given to everybody.

“No matter what people take from you, Don’t let them take away your Dignity”

Google’s Android and Apple’s iOS are operating systems used primarily in mobile technology, such as smartphones and tablets. Android, which is Linux-based and partly open source, is more PC-like than iOS, in that its interface and basic features are generally more customizable from top to bottom. However, iOS’ uniform design elements are sometimes seen as being more user-friendly.

Affordability

Apple has always been at the top end of the market in terms of pricing. The iPhone X is taking things to a whole new level with a starting price of $1,000. The iPhone 8 Plus starts from $800 and the iPhone 8 from $700. If you don’t want to spend that much, then you can go for the two-year-old iPhone 6S at $450 or the diminutive iPhone SE at $350. That’s as cheap as it gets unless you delve into the second-hand market.

For sheer scale and variety, nothing competes with Android. You can spend a lot if you want to, for example, Google’s new Pixel 2 phones and Samsung’s Galaxy Noteline match Apple’s iPhone pricing, but there’s also a huge choice of low-cost handsets from a wide variety of different manufacturers and the platform has been deliberately optimized to run on low-end hardware. The fact that Android also leads the field in free apps makes it the natural choice for the budget-conscious.

Winner: Android

 

Apps

Let’s start with a look at the numbers. This is roughly how many apps you’ll find in the Google Play Store and the Apple App Store:

• Android apps: 2.8 million
• iOS apps: 2.2 million

Truthfully, numbers aren’t the best metric because most of us only use a handful of apps and the most popular ones are available on both platforms. Traditionally, iOS has been a more lucrative platform for developers, so there has been a tendency for new apps to appear there first, but that is changing as Android’s market share continues to grow. In the U.S., iOS still leads the way, but developers elsewhere are increasingly targeting Android first.

The Play Store still has a higher percentage of free apps than the App Store. But the best mobile games still land on iOS first and they don’t always come to Android. Ultimately, quality beats quantity and so this is a narrow win for iOS.

Winner: iOS

Battery life and charging

As one of the biggest bugbears for smartphone owners, battery life is a huge factor.

Both Android and iOS allow you to see your battery usage at a glance, broken down by app, but only Android shows an estimate of how much battery life you have left. They both offer power saving modes that can extend your battery life by limiting performance, connectivity, and other power-sapping features, but precisely how it works is generally more customizable on Android.

For a long time, Android had an advantage in the charging department, because many Android phones offered fast charging capabilities and wireless charging. However, Apple’s iPhone 8, 8 Plus, and iPhone X all offer wireless charging and fast charging. It’s worth noting you have to buy the fast charging adapter separately, whereas it’s usually provided in the box with an Android phone.

This category is far from clear cut, but comparing similarly priced Android phones with iPhones, they tend to have longer battery life, so Android gets the win.

Winner: Android

Updates

Apple’s iOS offers consistent and timely software updates and security patches. If you want the same experience on Android, then you must buy one of Google’s Pixel phones.

If you want the latest features, bug fixes, and security updates, then you should choose iOS.

Winner: iOS

Customizability

This has always been one of Android’s main strengths. It’s very easy to theme your phone, you can set up the layout you want on your home screen, add widgets and shortcuts, and even change your entire user interface with launchers.

You can set backgrounds in iOS and there’s limited support for widgets, but you don’t have anything like the same level of freedom. Android also allows you to set up third-party apps as your default options for many things that are still locked down in iOS. If you enjoy tinkering, or you want a truly unique, personalized look for your home screen, then Android is the platform for you.

Winner: Android

Accessibility

Both platforms offer a good range of accessibility features. Ultimately, iOS is simpler and easier to use in some important ways. It’s uniform across all iOS devices, whereas Android is slightly different on devices from different manufacturers. We also think iOS is less cluttered and more streamlined than most Android phones, although Google’s stock Android is every bit as elegant and accessible.

Winner: iOS

Calls and messaging

Basic calling and messaging functionality is good on both platforms, but it can be confusing on Android. Google appeared to be folding everything into Hangouts, which allows messages, SMS, video chat, group chat, and more via Wi-Fi or your data network

There’s also Android Messages, which used to be called Google Messenger, and it’s the default texting app. To make matters worse, you’ll find many manufacturers like to offer their own alternatives. Many Android phones come with their own messaging and dialer apps in addition to Google’s messaging apps, or they eliminate the Google apps.

FaceTime and iMessage come pre-installed on every iPhone and iPad, so it’s remarkably easy to connect with your friends and family. While iMessage is very easy to use, it works best when communicating with other iPhone users. You’ll find third-party app integration, fun stickers, GIFs, and much more in iMessage. We give iOS the win for its consistency and ease of use.

Winner: iOS

Camera

This is a difficult category to call. In the past, we’ve argued that Apple does the best job capturing lighting, coloring, and other details, but the latest Android smartphones are casting a lot of doubt on that assertion. Google’s Pixel 2 and Pixel 2 XL boast the best cameras we’ve used so far, but the iPhone 8 Plus comes close and we expect the iPhone X camera to be something special.

The camera apps on both platforms are very good and very fast. For ease of use and best results without tweaking, the iOS camera app takes the cake. There’s more variation on Android simply because OEMs tend to add their own camera apps with lots of features, some good, some a bit gimmicky. We’re going to give this one to iOS, but with the caveat that the top Android phones, particularly the Pixel 2, offer the best smartphone camera experience around.

Winner: iOS

 

A personal computer must have a Bluetooth adapter in order to be able to communicate with other Bluetooth devices (such as mobile phones, mice and keyboards). A master Bluetooth device can communicate with up to seven devices. This network group of up to eight devices is called a piconet. A piconet is an ad-hoc computer network, using Bluetooth technology protocols to allow one master device to interconnect with up to seven active devices. Up to 255 further devices can be inactive, or parked, which the master device can bring into active status at any time.Bluetooth implements confidentiality, authentication and key derivation with custom algorithms based on the SAFER block cipher. In Bluetooth, key generation is generally based on a Bluetooth PIN, which has to be entered into both devices.On 28 March 2006, the Bluetooth Special Interest Group announced its selection of the WiMedia Alliance Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) version of UWB for integration with current Bluetooth wireless technology.Bluetooth exists in many products, such as phones, printers, modems and headsets. The technology is useful when transferring information between two or more devices that are near each other in low-bandwidth situations. Bluetooth is commonly used to transfer sound data with phones (i.e. with a Bluetooth headset) or byte data with hand-held computers (transferring files).Bluetooth simplifies the discovery and setup of services between devices. Bluetooth devices advertise all of the services they provide. This makes using services easier because there is no longer a need to setup network addresses or permissions as in many other networks.

1)      Don’t post any personal information online – like your address, email address or mobile number.

2)      Think carefully before posting pictures or videos of yourself.  Once you’ve put  a picture of yourself online most people can see it and may be able to download it, it’s not just yours anymore.

3)      Keep your privacy settings as high as possible

4)      Never give out your passwords

5)      Don’t befriend people you don’t know

6)      Don’t meet up with people you’ve met online.  Speak to your parent or carer about people suggesting you do

7)      Remember that not everyone online is who they say they are

8)      Think carefully about what you say before you post something online

9)      Respect other people’s views, even if you don’t agree with someone else’s views doesn’t mean you need to be rude

10)   If you see something online that makes you feel uncomfortable, unsafe or worried: leave the website, turn off your computer if you want to and tell a trusted adult. 

DEFINITION:

Internet is a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols.
