Paper Generation to AI Generation


Can you remember the times when everything was recorded by paper? It’s so long ago now that the current generation growing up probably doesn’t have the first clue that this ever happened !

Computers have gone viral in more ways than one, and they are now responsible for more tasks than we ever dreamed of. The chances are that this technological advancement will continue into the future, and who knows what will be down to IT in the days to come. Future generation will be AI Generation, name as Artificial Intelligence Generation. But, this is not good always. This should be affect on the human brain and learning system of the youth, young people, and rest of the world.

The 10 Best Tablets


Apple iPad MiniFrom £269

Apple’s iPad was the best tablet on the market from the moment it launched, thanks to more apps than anyone else, a beautiful screen and an ease of use that was peerless. Then the iPad Mini was launched. Despite Steve Jobs’ own reservations, it turns out that in fact the 8” screen size strikes the perfect balance between ease of use and portability. It feels more natural to integrate the iPad Mini into daily life than any other device – whether it’s checking a quick email, browsing the web or downloading an app, the Mini is an easier gateway. With a 4G version available, too, it’s got excellent connectivity wherever you are. The downside is that the full-size iPad’s screen is bigger and, on balance, the Mini doesn’t offer the best value for money when compared to other tablets. But it does offer the best user experience, at least until Android develops more of the ‘coffee table’ apps that make the iPad such a joy. The thin, lightweight design is unsurpassed.

Nexus 7From £159

A key part of the Nexus 7’s appeal comes from the open Android operating system, effortlessly integrating into Google and into the increasingly popular Android operating system; there are movies, films, books and music galore, as well as all your emails, maps and the rest, elegantly implemented.

But the single biggest plus point for the Nexus 7 is the price: for £159 you get a better screen than the iPad Mini and perfectly decent build quality from Asus. Now that the company has added a 3G option, there’s also permanent connectivity. And while Google Now really comes into its own on a phone, this feature predicts what you want to search for before you even know it (bus times when you get to a bus stop for instance) and also tells you when to leave for your next calendar appointment. Clever and affordable, the Nexus 7 is the best solution for many users.

Galaxy Note 2From £449

At 5.5”, the Galaxy Note 2 is both a phone and a tablet – hence the ‘phablet’ moniker. But as much of the appeal comes the unique S-Pen technology. This stylus allows you to garner extra information about what’s on the device’s screen simply by hovering above it, and the super fast processor means that this is a device that is as comfortable as a media consumption device as it is as a work unit. For some that means the Note 2 is neither one thing nor the other, but many people still use this it as their main, sole device. It may look like an over-sized phone, but its advantages are considerable. Large screen and impressive capabilities aside, it’s also blazing a new trail.

Microsoft Surface From £399

Microsoft’s Surface is the first tablet that the Windows-maker has built itself, and the idea is to show off Windows 8. The latest version of the operating system is built for touch screens such as the Surface, and indeed this device really does make the operating system make more sense than on a conventional laptop. There are trade-offs, however: Windows 8 is a fully fledged operating system, while the Surface RT only runs a cut down version, called Windows RT. While the Surface Pro runs the full version, it is more expensive, thicker and heavier. So if you want a lovely Windows RT tablet, running the growing but limited selection of Windows 8 apps, then the Surface RT is for you. But who actually wants that? So for now Surface feels like a lovely product with some great ideas, not least the ultra-slim keyboard. But it’s a device in search of a market. The Surface Pro, meanwhile, is more of a laptop replacement, and laptops are lighter and more capable.

Kindle Fire HDFrom £159

If you use the internet, you almost certainly use Amazon, and if you read books it’s increasingly certain that you also own a Kindle. The Kindle Fire HD is Amazon’s attempt to move those who already download books into the burgeoning category of those who also download music, film and TV. And while Amazon does indeed let you browse the web or use email on the Fire HD, more than anything else it is a device for browsing the company’s own store and watching media. As such, it’s got a lovely screen, offering a higher resolution than the iPad Mini at a far lower price. And in truth it does everything most people use a tablet of this size for. It’s hard to argue that that’s enough when the Nexus 7 costs the same price and offers a wealth of additional features, such as the entire Android app selection – but where Amazon excels is in making everything simpler, and that for many users is the appeal. Nifty additions such as X-Ray easily let you see whoever is on screen a film, too.

Galaxy Note 10.1£399 

Samsung’s Galaxy Note 10.1 is the company’s most serious attempt to change the face of computing yet – that A4 notepad can, Samsung hope, be replaced by this computerised version, which with the S-Pen you can write notes on, and then later on in the day you can watch films and TV shows too. It’s the ultimate work and play device, the company hopes, and can arguable take on the iPad on all fronts and more. Those are lofty ambitions and for early-adopting technology fans there is a lot to like in the Note 10.1. But it hardly heralds the paperless office yet, because the handwriting recognition isn’t perfect, and it also struggles because the screen isn’t up to the quality of its rivals. With 4G connectivity, however, there’s much to like the Note for – it’s a product for geeks for now, but it heralds at least part of the future. It’s also a super-charged version of the S-Pen-free Galaxy Tab 10.1.

Nexus 10From £319

Like the Nexus 7, Google’s Nexus 10 offers a great tablet at a really great price – unfortunately with the this larger model feels like it doesn’t quite have the class of the Nexus 7. That’s not because the screen isn’t fantastic, or because the build-quality isn’t perfectly decent. Rather it’s because of details, such as the way the case replaces the speaker cover, so you can’t easily remove it, and above all the fact that this good hardware revelas the lack of premium tablet apps for Android. On a screen this nice, there should be more to do than simply read books or watch films. Where the iPad provides that, with apps such as Leonardo Da Vinci’s Anatomy offering a novel experience, the Nexus 10 only reveals that Google has a way to go. But not being as good as the iPad is not a major barrier when the price is this attractive. Indeed, the Nexus 10 is still cheaper than the two-generations-old iPad 2.

Asus Transformer Prime Since £410

Asus make a wide range of tablets, but the Transformer Prime is the one that comes close to being both an excellent tablet and an excellent laptop – with the keyboard acting as a removable charging dock as well as a better way to type than on the touchscreen, as well as packing a powerful processor, this is a device for people who can get most of what they need doing done on a tablet but appreciate the convenience of a laptop. It suffers, however, from the weakenesses of Android as a tablet operating system and the equal lack of apps, and also from the fact that Android is not designed to operate laptops. So its Office software, for instance, is a compromise. But it’s one that works for Asus’s dedicated niche of users.

Cutting Edge Technology


Cutting-Edge Technology refers to existing and fully developed technology features, unlike bleeding-edge technology, which is so new that it creates unreliability risks to users. Although, commonly used to refer to computer and electronic technology, the term can apply to technology of any type, including automotive, medical, engineering and countless other industries.

Bangladeshi apparel makers are introducing cutting edge software technology in a bid to upgrade production processes and reduce fabric waste by raising measurement accuracy.


Intel Core i5 vs. Core i7


Intel Core i5 vs. Core i7.

These two chips look similar, with the same cache, almost the same clock speed, and similar GPUs–but they have different operating TDPs and hence offer different user experiences.

## Core i7 chips carry either 6MB or 4MB of cache. Core i5 chips run the gamut here. 
## Intel’s Core i7 processors are quad-core chips with Hyper-Threading enabled.
## Intel’s dual-core mobile Core i7 chips typically have higher clock speeds than their Core i5 counterparts, even at the same TDP.

UNIVAC I- First Commercial Computer


Today’s personal computers so much faster as well as too much intelligence that works enough restless, unbelievable and used in various difficult purposes, but the world’s first desktop computer, UNIVAC-I when invented in 1951, then that was used in 46 general purpose computers built.

1510895_746980745356563_3818292497795492432_n

The very first commercially “successful” computer was called UNIVAC I, which weighed 13 metric tons, consumed 125 kW and launched in 1951. A total of 46 systems was built and delivered to organizations. Today, more than 1.7 billion personal computers are used in the world.


Servlet Technology


Servlet technology is robust and scalable as it uses the java language. Before Servlet, CGI (Common Gateway Interface) scripting language was used as a server-side programming language. But there were many disadvantages of this technology. We have discussed these disadvantages below.

There are many interfaces and classes in the servlet API such as Servlet, GenericServlet, HttpServlet, ServletRequest, ServletResponse etc.

What is a Servlet?

Servlet can be described in many ways, depending on the context.

  • Servlet is a technology i.e. used to create web application.
  • Servlet is an API that provides many interfaces and classes including documentations.
  • Servlet is an interface that must be implemented for creating any servlet.
  • Servlet is a class that extend the capabilities of the servers and respond to the incoming request. It can respond to any type of requests.
  • Servlet is a web component that is deployed on the server to create dynamic web page.

What is web application?

A web application is an application accessible from the web. A web application is composed of web components like Servlet, JSP, Filter etc. and other components such as HTML. The web components typically execute in Web Server and respond to HTTP request.
