Hadoop Technology

Introduction:-

       Hadoop is a new technology. Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware. It provides massive storage for any kind of data, processing power and the ability to handle virtually limitless concurrent tasks or jobs.

History:-

        As the World Wide Web grew in the late 1900s and early 2000s, search engines and indexes were created to help locate relevant information amid the text-based content. In the early years, search results were returned by humans. But as the web grew from millions of pages, automation was needed.

Why is Hadoop important?

• Ability to store and process huge amounts of any kind of data, quickly. With data volumes and varieties constantly increasing.
• Computing power.
• Fault tolerance.
• Flexibility.
• Low cost. The open-source framework is free and uses commodity hardware to store large quantities of data.
• Scalability. You can easily grow your system to handle more data simply by adding nodes. Little administration is required.

What are the challenges of using Hadoop?

• MapReduce programming is not a good match for all problems.
• There’s a widely acknowledged talent gap.
• Data security– it is also provide data security for hadoop and big data users.
• Full-fledged data management and governance. Hadoop does not have easy-to-use, full-feature tools for data management, data cleansing, governance and metadata.

How Is Hadoop Being Used?

• low-cost storage and data archive.

  

• Sandbox for discovery and analysis.
• Data Lake.
• Complement your data warehouse.

What is Big Data?

Introduction:

            Big data is a term that describes the large volume of data ` both structured and unstructured ` that inundates a business on a day-to-day basis. But it’s not the amount of data that’s important. It’s what organizations do with the data that matters. Big data can be analyzed for insights that lead to better decisions and strategic business moves for any organizations or company.

History:

            While the term “big data” is relatively new, the act of gathering and storing large amounts of information for eventual analysis is ages old. The concept gained momentum in the early 2000s when industry analyst Doug Laney articulated the now-mainstream definition of big data as the three Vs:

1. Volume:-Organizations collect data from a variety of sources, including business transactions, social media and information from sensor or machine-to-machine data.
2. Velocity:-Data streams in at an unprecedented speed and must be dealt with in a timely manner.
3. Variety:-Data comes in all types of formats ` from structured, numeric data in traditional databases to unstructured text documents, email, video, audio, stock ticker data and financial transactions.

Why Big Data important?

The importance of big data doesn’t revolve around how much data you have, but what you do with it. You can take data from any source and analyze it to find answers that enable 1) cost reductions, 2) time reductions, 3) new product development and optimized offerings, and 4) smart decision making. When you combine big data with high-powered analytic, you can accomplish business-related tasks such as:

• Determining root causes of failures, issues and defects in near-real time.
• Generating coupons at the point of sale based on the customer’s buying habits.
• Recalculating entire risk portfolios in minutes.
• Detecting fraudulent behavior before it affects your organization

Who uses Big Data?

Today’s life we have large amount of information to gathering and storing but that doesn’t matter how much amount of data you have.

Below points shows where big data is important-

• Education
• Government
• Healthcare
• Banking
• Manufacturing
• Retail etc.

Introducing Chrome Operating System

Chrome Operating System – A New Era for Web Developers and Designers

By Awadhesh Kumar, Jain Software Developers

Introduction

We are all familiar with popular operating systems like Windows, Linux, Unix, and macOS. However, there’s another powerful and modern system developed specifically for the web — Google’s Chrome Operating System (Chrome OS).

Chrome OS is a Linux kernel-based operating system created by Google. It is designed to work seamlessly with web applications and cloud-based tools. Unlike traditional operating systems, Chrome OS focuses primarily on online tasks, making it a perfect fit for users who spend most of their time on the internet.

History of Chrome Operating System

Google announced Chrome OS on July 7, 2009. The project originally began as an open-source initiative called Chromium OS. Later, Google officially released Chrome OS to the public on November 19, 2009.

The goal behind the Chromium project was to create an operating system that provides a fast, simple, and secure computing experience — especially for users who depend heavily on web-based applications. Over the years, Chrome OS has evolved into a reliable, lightweight, and efficient system used in Chromebooks worldwide.

Advantages of Chrome Operating System

1. Web-Centric Design
Chrome OS is designed for users who primarily work online. It functions as a pure web client OS, allowing smooth operation of web applications without unnecessary local processes.

2. Speed and Efficiency
The system is optimized for fast booting, quick performance, and efficient multitasking. It provides faster data handling and web-based calculations compared to many traditional operating systems.

3. Lightweight and Secure
Chrome OS is lightweight and consumes minimal system resources. Since it is based on Linux, it inherits strong security features, making it resistant to most common viruses and malware.

4. Frequent Updates and Integration
Google frequently updates Chrome OS to enhance stability, security, and compatibility with new web standards. It also provides access to numerous APIs that developers can use to create advanced web applications.

5. Optimized for Chrome Browser
The entire operating system is designed to make the Chrome browser run more efficiently than on any other platform. The hardware in Chromebooks is tailored for this specific purpose, ensuring smooth browsing and application performance.

Limitations of Chrome Operating System

Why php is Light Weight?

We all know php is server side scripting language, basically it is user for programming purpose for designing the web site but we can also use as general purpose programing language.

Firstly, it is introduce in 1994 by Rasmus lerdorf and his group. As its name implies php, stand for hypertext preprocessor before this language is going to popular, is known as Personal Home Page tools and is use for tracking the resume etc.

Basically php is combination of two languages that’s C and Perl that’s reason behind its syntax look like C programming language. Today we see several number of versions like php 1.0, php 2.0, php 3.0 and

today we have latest version of php that’s php 7.0.

We can easily embedded the php code into html code, and it can combine in various web templates easily. Php codes are easily interoperated by web-servers without any king of troubles and get the output very fast.

At the beginning time php works under the ZEND Engine and executing the php code using Zend interpreter.

Actually php is open source product and users can easily download from the internet. And it is compatible with MySQL server that is also an open source product.
