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.


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.


Broadwell: Look at Intel’s Low-Power Core M with 14Nanometer [nm] Process


A look at Intel’s Low-Power Core M and its 14nm (nanometer) process. This New chip will have a lot to offer. Intel isn’t giving out specific performance or power consumption numbers for its new processors.
# Intel’s 14nm process refines the ” Tri – Gate ” transistor technology the company introduced in its 22nm process.
# The next Atom CPU architecture, a “tick”-style shrink of Silvermont named Airmont, will also use the 14nm manufacturing process.Core-M-640x360

There’s good and bad news on this front. The good news is that Intel has 14nm production in what it deems a “healthy range,” and the “lead product” for 14nm is in volume production and shipping to PC OEMs now—that would be the Core M, which we’ll discuss in more detail later. “Further improvements” to the process are still being made, and, at some point in 2015, Intel thinks yields will improve to roughly the level that the 22nm process is at right now.

Broadwell chips will be Intel’s first to use the 14nm process, and, of all the chips that will eventually ship with Broadwell, the low-power Core M family will be the first. This isn’t the first time Intel has talked about Core M—it was first mentioned at this year’s Computex in June.14nm-breakdown

As we reported then, Core M is a new name, but it’s not necessarily a new class of product. It’s just the new name for Intel’s Y-series parts, the slowest and most battery-friendly chips in Intel’s CPU lineup to be based on its flagship architecture (they occupy the space between the U-series processors you’d find in a MacBook Air and most Ultrabooks and the Atom chips you can find in lower-end tablets, convertibles, and laptops). Previous, Y-series chips used the same Core i3, i5, and i7 badges as other CPUs, but that will no longer be true for Broadwell.

Broadwell should have some features ::

IBM’s Cognitive Computing | Changing Healthcare

For the first time, IBM will open up Watson as a development platform in the Cloud to spur innovation and fuel a new ecosystem of entrepreneurial software app providers who will bring forward a new generation of applications infused with Watson’s cognitive computing intelligence.

Since winning Jeopardy! in 2011, its unique abilities as a cognitive computing system have enabled IBM Watson to help doctors better treat cancer patients, to support financial advisers and offer the most up-to-date guidance and to provide call center staff the perfect solutions at their fingertips. Indeed, IBM recently announced the new billion-dollar IBM Watson Group to solve the real-world problems that Watson is so adept at.ibm-watson-questions

” A new cognitive computing project that enables more natural interaction between physicians, data and electronic medical records as well as help doctors better treat cancer patients, to support financial advisers and offer the most up-to-date guidance and to provide call center staff the perfect solutions at their fingertips. “

IBM Watson* technology is about to change your life. Because cognitive computing is altering how information is gathered, analyzed and presented, Watson is becoming your decision-making ally. In its latest announcement, IBM is pairing Watson with organizations to bring you improved customer service and information to help make intelligent decisions. Two years ago, Watson made its reputation on “Jeopardy!” by besting the human champions. Since then, Watson has become faster and smarter, enabling IBM to offer Watson-based technologies for medical and consumer-based services. This breakthrough in cognitive computing wouldn’t be possible without Power Systems* servers.

Think Like a Human

Cognitive computing technology allows Watson to read and digest material, understand natural language and present confidence-weighted, evidence-based responses. On one level, cognitive computing simulates the behavior of the human mind around an aspect of cognition, such as understanding language and being able to answer a question. Cognitive computing is critical to managing the super-convergence occurring between mobile, social, cloud and analytics. Watson uses its cognitive skills to navigate the complexity of human speech and analyze vast amounts of disparate, unstructured data.

One in five diagnoses are incorrect or incomplete and nearly 1.5 million medication errors are made.

Assisting Cancer Treatment

Once a doctor sequences your full genome as well as your cancer’s DNA, mapping that information to the right treatment is difficult. Today, these types of DNA-based plans, where available, can take weeks or even months. Cognitive systems will decrease these times, while increasing the availability by providing doctors with information they can use to quickly build a focused treatment plan in just days or even minutes – all via the cloud.

Within five years, deep insights based on DNA sequencing will be accessible to more doctors and patients to help tackle cancer. By using cognitive systems that continuously learn about cancer and the patients who have cancer, the level of care will only improve. No more assumptions about cancer location or type, or any disease with a DNA link, like heart disease and stroke.

Healthcare is the first place Watson found work. The volume of healthcare information is enormous, encompassing medical journals, patient records, doctors’ notations and test assessments. “Watson is uniquely positioned to learn from and train on that data to get progressively smarter and to benefit the healthcare industry,” Gold explains. Technology healthcare products based on Watson are being brought to market by WellPoint Inc., a healthcare insurer, and reflect the partnership’s work with leading cancer institutions like the Memorial Sloan-Kettering Cancer Center.
