Computers: Then and Now

Santa Clara: Changes are the phenomenal process in the universe since its evolution. Remember the animated series of Mickey Mouse! The cartoon was a two dimensional series. But today, the technology has turned its head high. We are going to experience the four dimensional movies. And this is made possible by the ever enhancing technology and improving innovation techniques in "Computers". Ever since Charles Babbage invented computer, it has undergone several changes. Now is the time for Tablets. 


Let us have a look on the five generations of computer and what it looks today.

The First Generation (1940-1956)

UNIVAC I was the first computer of the first generation. The first computers used vacuum tubes for circuitry and magnetic drums for memory and took an entire room. They were very expensive to operate and used great deal of electricity and generated a lot of heat.

The Second Generation (1956-1963)

Transistors replaced vacuum tubes and ushered in the second generation of computers.
Superior than the vacuum tube, allowing computers to become smaller, faster, cheaper, energy-efficient and more reliable than the first generation computers. 


The Third Generation (1964-1971)

The third generation of computers saw the miniature form of transistors which was placed on 
Silicon chips called semiconductors, which increased the speed and efficiency of computers.
Users interacted with the computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run different applications at one time with a central program monitoring the memory. 


The Fourth Generation (1971-present)

The microprocessor brought the fourth generation of computers.
Thousands of integrated circuits we are built onto a single silicon chip. In 1981, IBM introduced its first computer for the home user and in 1984 Apple introduced Macintosh.

www. Turns "20". What's next?

No one knew that the invention of World Wide Web around twenty years ago by Tim Berners-Lee would make such a mark in most individual's life globally. It has brought a revolutionary mark in human history. He started with a simple design of a website with few hyperlinks and some text to describe a project and fundamentally changed the world.

The initial stage did not gain momentum, but gradually the power of the internet went on in the fingertips of users, quite literally. According to a report by Netcraft, there were 215,675,903 websites with domain names and content on them in February 2009. This shows the spreading web of the World Wide Web over the world. Web has already brought the world on a single and small platform. We are now able to share our thoughts and views at the touch of a finger through instant messaging and video chat. So, what is next? Where is this World Wide Web marching? 

The Semantic Web will be the next phase of web. It will see metadata, designed to be read by machines rather than humans. Lee coined the term by describing it as a web of data that can be processed directly and indirectly by machines. The giant global graph of linked data will allow apps to automatically create new meaning from all the information out there. The search engine might become more apt and devised to understand our search requirements and show the exact result. We might not require keep on dragging the page to find the answer to our questions.

Web has transformed the way people see the world, their purchasing behavior and many more. With their busy schedule, population in the Tier II and III cities are inclining more towards online purchase. Your smart phone is the best example. Web has provided you the power to experience the three-dimensional feel of a product advertisement as if you are watching it live making the buying experience livelier.

However, may be the future of web holds a lot more than this. Imagine of getting live traffic information from the local roads, getting information about vacant seat from the train itself, plants sending you email asking to water them, all the legal formalities required for a business might be done over email. These are mere thoughts. The web might gift us much more.

12 Lesser-Known Google+ Tips

 You may have started using Google+, but did you know that you could edit photos in it? Integrate it with other social networks? Or video Chat in HD? Like with any new service, there are a lot of hidden features and lesser-known tricks in Google+, just waiting to be explored. Hitesh Raj Bhagat & Karan Bajaj offer 12 killer tips just as Google+ goes out of beta



1 If you have commented on a  post, but do not want  notifications of the follow-up comments coming to your inbox, there is a simple way out. Go to the original post and on the right side you will see a drop down arrow. Click on the arrow and select 'mute conversation'. You can choose to shut off all notifications from Google+ settings as well.

2 If you do not want others to see the people in your Circles, go to your profile page and click on ‘edit profile’. On the left side, you will see a small grey disc just above the photographs of your Circle members. Click on the disc and in the box that opens, you can choose the visibillity of your circle members.

3 You can setup Google+ to send notifications to your mobile phone as well.
Click on the gear icon on the top right corner and select Google+ settings.
On the page that opens, go to ‘delivery preferences’ and under your email address you’ll see the option to add a mobile number to receive push notifications. Enter your phone number and Google will first send you a verification code. After verification, you will start receiving free notifications on your phone by sms.

4 By default, video chat in Google+ uses standard definition video, but if your webcam supports it, you can enable HD video support. First, sign in to chat, hover the mouse cursor over the chat section on the Google+ page, click on the small triangle that appears and then click on settings. Here, you'll see a checkbox to enable HD video chat.

5 There is a built-in basic photo editor in Google+ as well. Select
any of the photos uploaded to your profile and double click on it to edit. It will open the image in a full page — click on the 'actions' box below the image and here you can rotate the photos or click on edit to apply a variety of basic effects and tune-ups.

6 The Circle feature can be used to save various shared links and notes if you want to read them later. Go to Circles, create a new Circle, name it whatever you want (like ‘Read Later’) and do not add anyone in it (Google calls it an Empty Circle).
Now, whatever you want to read later, share it on your Google+ status with only this empty Circle that you have created. It will work as your online repository for bookmarks, videos and any other thing you want to access later.

7 To add a faux banner to your Google+ profile page, you will need to do a bit of photo cropping and resizing using an image editing program. Paste a photo into a template, 750 pixels wide and 150 pixels high and resize it to fit. Then, split this image into 5 smaller photos, each with a dimension of 150 x 150 pixels. Go to your profile page, click on 'edit profile' and upload the images in the order that you want.

8 To share your location with a person or a circle, first click the share button on the top right of the Google+ page, then click the 'add your location' button in the text box that pops up. You may have to click 'allow' if a webpage notification comes up. Once Google+ has determined your location, just add names to add them to the share list, or add a complete Circle.

9 Using Google Chrome with Google+ gives you a whole host of new things to play with, thanks to free extensions. For example, an extension called Helper for Google+ allows you to share your Google+ posts to Twitter, while an extension called Surplus integrates Google+ right into the browser. With it, you can post/share though a pop-up or get desktop notifications even if the Google+ webpage is not open.

10 Let's say you want to share a specific post with someone new to Google+ — the easiest way to do this would be to share a permalink (permanent link). To get a permalink for a specific post, simply click the time stamp in the post — and it will open in a new page. Copy this link to share with anyone over email or chat, even if they don't have a Google+ account.

11 Google+ allows you to post updates in a variety of styles. To post in bold, add an asterisk at the beginning and end of the word (i.e., * word *). To post in italics, add an underscore before the word and a plus sign after it (i.e., _ word +). To post with a strikethrough, add a dash before and after the word (i.e., - word -).

12 To add your various other social networking websites or contacts to your Google+ profile page, first go to Google+ settings by clicking on the gear icon in the top right of the page. Then click on ‘connected accounts’ and add the accounts here. For instance, to add your Facebook account, type
http://facebook.com/ yourusernamein the box.
