Wordpress

WORDPRESS

      

WordPress started in 2003 with a single bit of code to enhance the typography of everyday writing and with fewer users than you can count on your fingers and toes. Since then it has grown to be the largest self-hosted blogging tool in the world, used on millions of sites and seen by tens of millions of people every day.

Everything you see here, from the documentation to the code itself, was created by and for the community. WordPress is an Open Source project, which means there are hundreds of people all over the world working on it. (More than most commercial platforms.) It also means you are free to use it for anything from your recipe site to a Fortune 500 web site without paying anyone a license fee and a number of other important freedoms.

A Little History

WordPress was born out of a desire for an elegant, well-architectured personal publishing system built on PHP and MySQL and licensed under the gplv2 (or later). It is the official successor of b2/cafelog. WordPress is fresh software, but its roots and development go back to 2001. It is a mature and stable product. We hope by focusing on user experience and web standards we can create a tool different from anything else out there.

 Features of wordpress-

• Simplicity Simplicity makes it possible for you to get online and get publishing, quickly. Nothing should get in the way of you getting your website up and your content out there. WordPress is built to make that happen.
• Flexibility With WordPress, you can create any type of website you want: a personal blog or website, a photoblog, a business website, a professional portfolio, a government website, a magazine or news website, an online community, even a network of websites. You can make your website beautiful with themes, and extend it with plugins. You can even build your very own application.
• Publish with Ease If you’ve ever created a document, you’re already a whizz at creating content with WordPress. You can create Posts and Pages, format them easily, insert media, and with the click of a button your content is live and on the web.
• Publishing Tools WordPress makes it easy for you to manage your content. Create drafts, schedule publication, and look at your post revisions. Make your content public or private, and secure posts and pages with a password.
• User Management Not everyone requires the same access to your website. Administrators manage the site, editors work with content, authors and contributors write that content, and subscribers have a profile that they can manage. This lets you have a variety of contributors to your website, and let others simply be part of your community.
• Media Management They say a picture says a thousand words, which is why it’s important for you to be able to quickly and easily upload images and media to WordPress. Drag and drop your media into the uploader to add it to your website. Add alt text, captions, and titles, and insert images and galleries into your content. We’ve even added a few image editing tools you can have fun with.
• Full Standards Compliance Every piece of WordPress generated code is in full compliance with the standards set by the W3C. This means that your website will work in today’s browser, while maintaining forward compatibility with the next generation of browser. Your website is a beautiful thing, now and in the future.
• Easy Theme System WordPress comes bundled with two default themes, but if they aren’t for you there’s a theme directory with thousands of themes for you to create a beautiful website. None of those to your taste? Upload your own theme with the click of a button. It only takes a few seconds for you to give your website a complete makeover.
• Extend with Plugins WordPress comes packed full of features for every user, for every other feature there’s a plugin directory with thousands of plugins. Add complex galleries, social networking, forums, social media widgets, spam protection, calendars, fine-tune controls for search engine optimization, and forms.

• Built-in Comments Your blog is your home, and comments provide a space for your friends and followers to engage with your content. WordPress’s comment tools give you everything you need to be a forum for discussion and to moderate that discussion.
• Search Engine Optimized WordPress is optimized for search engines right out of the box. For more fine-grained SEO control, there are plenty of SEO plugins to take care of that for you.
• Multilingual WordPress is available in more than 70 languages. If you or the person you’re building the website for would prefer to use WordPress in a language other than English, that’s easy to do.
• Easy Installation and Upgrades WordPress has always been easy to install and upgrade. If you’re happy using an FTP program, you can create a database, upload WordPress using FTP, and run the installer. Not familiar with FTP? Plenty of web hosts offer one-click WordPress installers that let you install WordPress with, well, just one click!
• Importers Using blog or website software that you aren’t happy with? Running your blog on a hosted service that’s about to shut down? WordPress comes with importers for blogger, LiveJournal, Movable Type, TypePad, Tumblr, and WordPress. If you’re ready to make the move, we’ve made it easy for you.
• Own Your Data Hosted services come and go. If you’ve ever used a service that disappeared, you know how traumatic that can be. If you’ve ever seen adverts appear on your website, you’ve probably been pretty annoyed. Using WordPress means no one has access to your content. Own your data, all of it — your website, your content, your data.

                     

• Freedom WordPress is licensed under the GPL which was created to protect your freedoms. You are free to use WordPress in any way you choose: install it, use it, modify it, distribute it. Software freedom is the foundation that WordPress is built on.
• Community As the most popular open source CMS on the web, WordPress has a vibrant and supportive community. Ask a question on the support forums and get help from a volunteer, attend a WordCamp or Meetup to learn more about WordPress, read blogs posts and tutorials about WordPress. Community is at the heart of WordPress, making it what it is today.

Contribute You can be WordPress too! Help to build WordPress, answer questions on the support forums, write documentation, translate WordPress into your language, speak at a WordCamp, write about WordPress on your blog. Whatever your skill, we’d love to have you!

Developer features

For developers, we’ve got lots of goodies packed under the hood that you can use to extend WordPress in whatever direction takes your fancy.

• Plugin System The WordPress APIs make it possible for you to create plugins to extend WordPress. WordPress’s extensibility lies in the thousands of hooks at your disposal. Once you’ve created your plugin, we’ve even got a plugin repository for you to host it on.
• Theme System Create WordPress themes for clients, customers, and for WordPress users. The WordPress API provides the extensibility to create themes as simple or as complex as you wish. If you want to give your theme away for free you can give it to users in the Theme Repository

Application Framework If you want to build an application, WordPress can help with that too. Under the hood WordPress provides a lot of the features that your app will need, things like translations, user management, HTTP requests, databases, URL routing and much, much more.           

 

• Custom Content Types WordPress comes with default content types, but for more flexibility you can add a few lines of code to create your own custom post types, taxonomies, and metadata. Take WordPress in whatever direction you wish.

The Latest Libraries WordPress comes with the latest script libraries for you to make use of. These include jQuery, Plupload, Underscore.js and Backbone.js. We’re always on the lookout for new tools that developers can use to make a better experience for our users.

                                      

Sundar Pichai in SRCC College

  

                                       SUNDAR PICHAI

Google fans woke up to a surprise restructuring on Monday (Tuesday in India). One that the search-focused Google will now be a subsidiary of a new parent company called Alphabet inc. headed by the CEO of Google Larry Page. And replacing Page as the CEO of Google is India-born Sundar Pichai. From discovering what technology can do through a rotary telephone to running the show for Android - the most popular mobile OS, Google's newest CEO has come a long way.

1. Sundar Pichai was born in Chennai and his family of four (Pichai, his mother, his father and younger brother) lived in a two-room apartment. Pichai was the captain of his school cricket team and under him, the crew won several competitions in the region.

2. Growing up, Pichai had neither a television nor did his family own a car. They would either all hop on to their blue Lambretta scooter or use public transport.

3. The two sons slept in the living room. Pichai's mother was a stenographer until she had her sons and his father was an electrical engineer for the British conglomerate GEC and managed a factory that made electrical components. His father introduced him to technology, by sharing stories and challenges he faced during his work day.

4. For Pichai, the wonders of technology were revealed to him when the family bought their first telephone. Pichai was just 12 years old and the rotary helped him realise his talent for numerical recall. He could remember every number he dialled, but did not know at the time, how useful this skill would be in the future.

5. He studied metallurgical engineering at IIT Kharagpur and was described by his teachers as "the brightest of his batch". He eventually earned himself a scholarship at Stanford.

6. His father, Regunatha Pichai applied for a loan in order to pay for his air tickets and other miscellaneous expenses. When it didn't come through, Regunatha withdrew the required amount from the family's savings - it was more than his annual salary.

7. Pichai surprised his parents - though probably not pleasantly at the time - by dropping out of Stanford to work as an engineer and product manager at Applied Materials, a semiconductor maker in Silicon Valley. However, he got an MBA from Wharton in 2002 and did a stint at McKinsey as a consultant.

8. In 2004, Pichai joined Google and was part of a team that worked on Google's search toolbar. He later proposed that Google create its own browser, for which he won the support of all the co-founders, but an objection from then CEO Eric Schmidt. Today, according to Adobe, Google Chrome holds 32 per cent of the browser market on phones and desktop PC.

9. Another product under Pichai's watch was Android, the world's most popular mobile operating system. In 2012 Google announced a version of Pichai's Chrome browser for Android, which would replace the mobile browser Rubin had developed within his own group. Andy Rubin founded Android in 2003 and sold it to Google in 2005, after which he successfully navigated the OS to keep Apple from dominating the market for the next eight years. In 2013, Page handed responsibility for Android over to Pichai, when Rubin felt he would be unable to integrate Android with the rest of Google.

10. Though Google usually waits until the fall to announce their annual version of Android, Pichai previewed the next release at Google's annual developer event, I/O, in May. This change in timing, which seems like no big deal, actually addresses a large problem Android hardware makers face - which was that an announcement the fall gave them no time to prepare for the holidays and it put them at a disadvantage to the company selected every year to develop a phone in partnership with Google.

SUNDAR PICHAI TO VISIT SRCC COLLEGE

Google top boss Sundar Pichai who is making his way to India to meet with Prime Minister Narendra Modiwill also be making an appearance in Delhi University at the Shri Ram College of Commerce on December 17.Pichai will be addressing and interacting with students at the college during the session 'Ask Sundar'. "We had invited Pichai and after his meeting with the PM, he will be coming to address our students," said a source close to the college. While it is not confirmed, Pichai is likely to launch the Google's Android One smartphone in India.

HARDWARE NETWORKING

                                  COMPUTER HARDWARE

It refers to objects that you can actually touch, like disks, disk drives,display screens, keyboards, printers, boards, and chips. In contrast,software is untouchable. Software exists as ideas, concepts, and symbols, but it has no substance.Books provide a useful analogy. The pages and the ink are the hardware, while the words, sentences, paragraphs, and the overall meaning are the software. A computer without software is like a book full of blank pages -- you need software to make the computer useful just as you need words to make a book meaningful.

                                             HARDWARE COMPONENTS

1.MOTHERBOARD

Now, the first thing is the motherboard. It's the basis of your computer. It's the first component installed in the system unit, and it holds all of the circuitry that ties the functions of the computer components together.

You can think of it like your car (which has many computer systems of its own). If you have a frame and tires, you've got a car (or you've got a system unit), but it won't take you very far! Now, add your engine - the motherboard - where all the systems tie in one way or another, and you've got the start of a working vehicle.

2.CENTRAL PROCESSING UNIT

The central processing unit, or the brains of the computer, sits on the motherboard and does actually have its own cooling fan. The processors now are so fast they need to be cooled down. All the instructions you give the computer - like a click of a mouse - go through the CPU, which processes in billions of cycles per second. 

3.RANDOM ACCESS MEMORY 

Random-access memory (RAM) is a type of computer data storage. A RAM device makes it possible to access data in random order, which makes it very fast to find a specific piece of information. Certain other types of storage are not random-access. For example, a hard disk drive and a CD will read and write data in a predetermined order. The mechanical design of these devices prescribes that data access is consecutive. This means that the time it takes to find a specific piece of information can vary greatly depending on where it is located on the disc.RAM devices are used in computer systems as the main memory. RAM is considered volatile memory, which means that the stored information is lost when there is no power. So, RAM is used by the central processing unit (CPU) when a computer is running to store information that needs to be used very quickly, but it does not store any information permanently.Present-day RAM devices use integrated circuits to store information. This is a relatively expensive form of storage and the cost per unit of storage is much higher than for devices like a hard drive. However, the time to access data is so much faster for RAM that speed outweighs cost. A computer therefore uses a certain amount of RAM for fast-access, temporary storage of information and a much larger amount of non-random, permanent mass storage, like a hard disk drive. For example, a typical computer system may have two to eight GB (gigabytes) of RAM. 

3.CACHE MEMORY

Cache memory, also called CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.The basic purpose of cache memory is to store program instructions that are frequently re-referenced by software during operation. Fast access to these instructions increases the overall speed of the software program.As the microprocessor processes data, it looks first in the cache memory; if it finds the instructions there (from a previous reading of data), it does not have to do a more time-consuming reading of data from larger memory or other data storage devices.Most programs use very few resources once they have been opened and operated for a time, mainly because frequently re-referenced instructions tend to be cached. This explains why measurements of system performance in computers with slowerprocessors but larger caches tend to be faster than measurements of system performance in computers with faster processors but more limited cache space.Multi-tier or multilevel caching has become popular in server and desktop architectures, with different levels providing greater efficiency through managed tiering. Simply put, the less frequently access is made to certain data or instructions, the lower down the cache level the data or instructions are written.

4.READ ONLY MEMORY(ROM)

Computer memory on which data has been prerecorded. Once data has been written onto a ROM chip, it cannot be removed and can only be read.Unlike main memory (RAM), ROM retains its contents even when the computer is turned off. ROM is referred to as being nonvolatile.

TYPES OF ROM

Programmable Read-Only Memory (PROM)
Electrically Programmable Read-Only Memory (EPROM)
Electrically Erasable Programmable Read-Only Memory (EEPROM; also called Flash ROM)
Electrically Alterable Read-Only Memory (EAROM)

5.MOUSE

A device that controls the movement of the cursor or pointer in a display screen. A mouse is a small object you can roll along a hard, flat surface. Its name is derived from its shape, which looks a bit like a mouse, its connecting wire that one can imagine to be the mouse's tail, and the fact that one must make it scurry along a surface. As you move the mouse, the pointer on the display screen moves in the same direction. Mice contain at least one button and sometimes as many as three, which have different functions depending on what programe  is running. Some newer mice also include a scroll wheelfor scrolling through long documents.

6.KEYBOARD

A keyboard is the set of typewriter-like keys that enables you to enter data into a computer and other devices. Computer keyboards are similar to electric-typewriter keyboards but contain additional keys. 

7.MODEM (mō´dem) (n.) Short for modulator-demodulator

A modem is a device or programe  that enables a computer to transmit data over. for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.
