Caffeine to Hummingbird: An Upgrade to Google Search Algorithm!

Google Hummingbird is the New Search Algorithm
Most of the internet users have no idea about how the search engine works. The system that a search engine applies to find the relevant results among millions of websites is called Search Algorithm. Whether you will find an appropriate result from a search depends on the algorithm. With a powerful Search Algorithm, Google is the top search engine of the world. And recently a new search algorithm, called Hummingbird, has been launched by the search giant. 

Septermber 26, 1998. The starting of Google. And just yesterday, Google celebrated their 15th Birthday. This birthday was not a mere celebration actually. Moreover it comes with an annoucement of major change in Google Search Engine Algorithm. It's been 3 years since Google made a major change in their search algorithm named as Caffeine. And the new one, Hummingbird, has been lunched one month ago. 

Amit Singhal, senior vice president of search, said on Thursday- the company launched its latest "Hummingbird" algorithm about a month ago and that it currently affects 90 percent of worldwide searches via Google.

What's New in Hummingbird? 

  • Capable of handling large and complex queries
  • Precise and Faster Processing of Queries
  • Focus on the meaning behind the query words
  • Pay more attention to earch word in a query
  • Consider the relevance of the pages rather than focusing on the page rank only. 
  • Improved converstional search (People When Speaking Searches) 

These are all I've been able to gather about Hummingbird. Because, Google didn't inform much about it. I've collected those information from different websites. Let's discuss some other issues: 

What about Pagerank? 

Most of you know that pagerank indicates the overall quality of a site. But in Google search, pagerank is not everything. There are more than 200 search signals used by Google to sort search results. And pagerank is one of them. 

Hummingbird considers pagerank too. But it emphasizes on the relevance of the query. If the search query matches your contents, no matter who you are and what is your ranking, you will be the in the first page. And that's how Marks PC Solution competes with storng sites even with a page rank 0. 

Is there any Feature of Caffeine? 

Sure! Some parts of old search algorithm is still being used by Hummingbird. It just changes the unncessary parts and adds some new. But nobody can guarantee about the old parts. Because they could be changed anytime if Google finds something better. 

What Happened to Updates like Penguine, Panda etc?

From time to time, Google updated their algorithm. Sometimes they added new tools like penguine, panda etc. Some of them are being cosidered as the parts of old engine in a new engine. I mean, these were not changed entierly. 

What about SEO

As the search algorithm changes, SEO experts and site developers may think of change in ther optimization techniques. Though Google assures that no change is necessary. It said there is nothing to worry about SEO. 

But I personally don't believe this. Definitely the new algorithm will affect the search appearance of a site either positively or negatively. 

So far I know, Hummingbird doesn't hamper the search result position of Marks PC Solution. My suggestion is- Increase your Google+ Sharings. Grow your followers in Google Plus if you'd like to be favoured by Google!

Touchscreens Used with Smartphones

iPhone 5, Samsung S4, Windows Phone 8, Samsung Galaxy Tab

Basically this is a knowledge based article. It can just enrich your knowledge about display technology. And I think you will enjoy this. I'll try to provide you a brief idea about the screen technology used by the leading cell phone manufacturers. 

By this time you should know there are different types of display technologies such as LCD, LED, TFT, Retina etc. But how many of you know the details of each type? To be honest, I didn't have much idea about these before reading an article in a newspaper. Then I decided to write about smartphone screens on Marks PC Solution. I've also gathered information on display technology from different sites. 

TFT LCD Display (Thin Film Transistor Liquid Crystal Display)

This is the most widely used display technology at present. TFT LCD technology ensures the clear view. It is better than old LCD technology to view High Quality pictures and video. 

This type of display is relatively cheaper. So it can be used in low-priced phones too. 

But this technology has some limitations too. You can't operate your phone in sunlight. Your display will be almost unseen when you're in daylight. And this type of display consumes too much battery. You should keep the display off as much time as possible. 

IPS LCD Display (In-Plane Switching LCD)

IPS LCD is better than TFT LCD Display Technology. No matter how you wanna see it. You can get a clear view from any angle. It doesn't consume much power. That's why it saves your battery power. 

Manufacturing cost is little bit higher and used with medium-priced cell phones. 

Resistive Touchscreen Display (Don't Call it RTS!)

I've searched Google by RTS. Actually it has no short form. You should call it Resistive Touchscreen Display. 

In this technology, there are two layers in the screen. And there is a minor gap between the two layers. Whenever the first layer get your touch, the blank space between two layers blends and pressure the second layer. Immediately the processor gets signal. Thus Resistive Display Technology works. 

You can operate the phone using fingers or stylus. But using a stylus will be more comfortable. 

Capacitive Touchscreen Display

If you wanna operate your phone with fingers then capacitive display is more comfortable than resistive display. As made for operating with fingers, you can't use stylus or something else to work with capacitive display. 

This display ensures fast response time. Manufacturing cost is also high. This display is used with high-priced smartphones. 

OLED Display (Organic Light Emitting Diode) 

Most of you maybe familiar with only LED - Light Emitting Diode. More than a year ago, I wrote a post about the difference between LCD and LED. OLED is the improved version of LED technology. 

OLED is a high quality display technology for cell phones and monitors. It gives you a bright look. This type of display is very light and viewing angle is excellent. It supports 16 million colors and reponse time is very short. 

OLED display consumes less power and thus it saves your battery. 

AMOLED Display (Active Matrix LED)

Active Matrix OLED is a display technology that is used with mobile devices and televisions. It is actually an improved version of OLED. 

One of the great features of this display is the viewing capacity in sunlight. Users can see the screen in daylight without any problem. AMOLED ensures vivid picture with super sensitive screen. 

As the manufacturing cost is relatively higher, this type of display is used with high end mobile devices. 

Super AMOLED Display

Next to the AMOLED is Super AMOLED. It is nothing but the improved version of AMOLED developed by Samsung. This technology is used with the galaxy series devices. 

Super AMOLED includes the following features:

  • Light and thin
  • Vivid Display
  • Faster Reponsive Capacity
  • Less Power Consuming

Retina Display 

The most modern version of smartphone screen is the Retina Display, which is a combination of IPS LCD and Backlit LED technology. As developed by Apple, this type of display is only used with iPhone. 

It is a so high resolution display that you can't see the pixels with blank eyes. That's why it is named as Retina Display. 

Retina Display is very sharp, vivid and clear. 

Heptic Touchscreen Dispay

Nokia and BlackBerry are using this type of display technology. This display is capable of identifying the touch accurately. Thus it enables users to work with touchscreen comfortably. 

This display is reliable, comfortable and great for typing. And it's very popular among the users. 

Gorilla Glass Display

Maybe you can guess something about this display. Yes you're right. This display is made for rough and tough use. 

Gorilla Glass is very hard and durable display. It keeps your display out of scratch. Even it can protect the screen from hammer. Many cell phone manufacturers are now using Gorilla Glass in their devices. 

Here I've just discussed about 10 types of displays. And these have many variations. If you'd like to know more then search Wikipedia.

HTML Tutorial 6: Basic Elements of An HTML Form (Part 2)

In my previous post, I discussed about HTML form (Part 1). Same topic will be continued today and this is the Part 2. In part 1 you've learned creating Text Fields, Password Field, Radio Buttons and Checkboxes. In this post you will learn how to create Submit Button and Drop Down Menu. 

You should open Notepad from your PC to practice this lesson. Then save the html code with .htm or .html extension and then open the saved file with a browser to see the result. Let's begin: 

Drop Down Menu:

Let me begin with creating a drop down menu. This is very interesting as well as easy to create! 

Which one is your Favorite Cell Phone Brand? 

You must begin with the <select> tag and end with </select tag>. And every option of the list should start with <option> tag. Then you can type anything as you want. If you type the above text, your browser will show: 

Which one is your Favorite Cell Phone Brand? 

Submit Button:

Submit button is used to send data to the server. After filling up the form, an user need to confirm the email and submit it. 

<input type=submit> denotes a submit button. 

A simple submit button is very easy to create. You just need to write the following code: 

<input type=submit>

That's it. Now your browser will show:

It can be used as:

Username<input type=text>

You should use the following code to create a complete submit button: 

<form name="input" action="" method="get">

Username: <input type=text>
<input type=submit>

HTML Tutorial 5: Basic Elements on An HTML Form (Part 1)

Basic Elements on An HTML From

Few months ago, I started writing about HTML. There are already 4 tutorials published on HTML. I know this is not sufficient for an HTML learner. Because learning HTML requires much resources and practice. However I will try to write about HTML whenever I'm able to manage time. 

You can also read the previously published HTML Tutorial:

Today's HTML tutorial is very easy, funny and useful. Today I will discuss about the basic elements of an HTML form. This is the part 1 that includes Text Fields, Password Field, Radio Buttons & Checkboxes. 

How to Start: 

You can practice using notepad. Press Start + R > Type Notepad > Enter. Now copy or type the code from here. And save them as form.htm or use any other name. But the name should end with either .htm or .html. Then open the file in a browser. 

Let's begin - 

Usually an HTML form contains input elements like text fields, checkboxes, radio buttons, submit buttons etc. To create an HTML form you must use the <form> tag. Look at the structure below:


input elements


Though you skip the <form> tag, modern browsers can identify your form. But this is a basic rule for creating html forms. So you should start with <form> and end with </form>. 

Text Fields:

<input type="text"> indicates a one-line input field to enter text. 

First name: <input type=text><br>
Last name: <input type=text>
The result will be as below: 

First name:

Last name:
Note: <br> tag is used to create line break. Otherwise both fields will appear in a single line. The default width of a text field is 20 character. You can increase it as below: 

<form>Name: <input type=text size = 40><form>

The result will be: 


Password Field:

<input type="password"> defines a password field. Whenever someone types in a password field, the characters are shown as circles. 

Password: <input type=password>

The result will be: 


Radio Buttons:

<input type="radio"> refers to a radio button. Radio button allows user to choose a single item. After selecting an item, you can change it. But once selected, you can't undone it. 

<form>Which one do you like most?<input type=radio name=Mobile>Nokia<br><input type=radio name=Mobile>Samsung<br><input type=radio name=Mobile>Apple</form>

You will get:  

Which one do you like most?





<input type="checkbox"> defines a checkbox. Somewhat similar to radio buttons. But here an user can choose multiple items. And he can deselect the item any time! 


What is your Favorite Browser?

<input type=checkbox>Google Chrome<br>
<input type=checkbox>Firefox<br>
<input type=checkbox>Internet Explorer<br>
<input type=checkbox>Opera<br>
<input type=checkbox>Other<br>
Your browser will show: 

What is your Favorite Browser?

Google Chrome


Internet Explorer



These are some important elements of an HTML form. There are few other elements remaining. I will try to write about those elements in the next post. And then I'll put these all together and show you how to prepare an HTML form. Till then, stay with us . . .

Google Unit & Currency Converter

Search Page Currency & Unit Converter by Google

The general idea about Google is it's a search engine. Though many people are familiar with the different services of Google, but only few of them know how to use Google smartly. Yeah! I mean it . . .

Maybe you know about how to use Google as Calculator. Google also gives you the interface of a scientific calculator if you type scientific calculator in the search box. I've written some posts about these topics. If you're not familiar with these, you can read . . . 

Today I'm gonna show two more tips of Google! You can use Google as Converter. Google let you convert currency and unit. 

Unit Converter: 

You can convert from one unit to another by Google Unit Converter
  1. Simply open Google Home Page
  2. Type Unit Converter and press Enter
  3. Immediately you will get a conversion interface at the top of search results

First you have to choose a category. Let's consider Speed. Then choose Miles/hour from the left box and Km/hour from the right box. Type 100 in the Mile box and get 160.934 Km as result! 

Search Page Unit Converter by Google

Currency Converter: 

Google also let you convert from one currency to another. You can convert Euro into Dollar or Dollar into Pound. The procedure is same as Unit Conversion.
  1. Open Google Home Page 
  2. Type Currency Converter and press Enter
  3. Get the converter immediately

Search Page Currency Converter by Google

There are two options to choose currencies. Let's choose US Dollar in the first box. And Euro in the next. Type 1 in the dollar box and get 0.76 as result in the Euro box. 

You should notice the conversion rate at the top. 1 US Dollar Equals to 0.76 Euro. This conversion process is alive. Rates may change frequently. 

Google tries to provide you the most recent rate. But it can't guarantee the accuracy of the exchange rate. 

You can also read Currency Conversion Disclaimer


By the way, I'm having trouble to use the currency converter and unit converter. Don't know for how long time this problem will prevail. When I'm searching by Unit or Currency Converter, even calculator, only search results appear. There is no converter or calculator!
However you can use this tool to convert currency. This is also very cool!
