Folder hiding process (trick) is really an interesting process in order to hide your data. You can easily hide your folder in windows operating system and you can hide your folder in two different ways as based on you.
First way is to select that folder which you want to hide and then, right click from your mouse on that folder. After right click, a list will appear as just click on properties and select check-box named ‘hidden’ in order to hide that folder and click on OK button.
Once close that wizard or change your location and again enter that location or wizard as you would found that your folder is hidden. In this way, you can hide folder.
If you want to unhidden that folder then, you need is to go to- Start -> Control Panel -> Appearance and Themes -> Folder Options.
After click on Folder Options as you will get folder options wizard then, click on view menu and select check-box named ‘show hidden files and folders’ and click on OK button in-order to unhidden.
Now, check that folder as it is unhidden. In this way, you can unhidden that folder.
Second way is unique and perfect in order to hide as select that folder which you want to hide and then, right click from your mouse on that folder. After right click, a list will appear as just click on properties.
After click on properties, properties wizard will appear then, click on View – Customize – Change Icon. Then, Change Icon wizard will appear as choose blank or we can say that hide icon in order to hide that folder and click on OK - Apply – OK button.
Now, time to hide folder name as for this go to- Start -> Run and there enter ‘charmap’ and click on ok button.
Then, Character Map wizard will appear as there, select empty character and copy that character and close that wizard.
Now, right click on that folder and click on ‘rename’ as paste (Ctrl+V) that empty character. Finally, your whole folder is successfully hidden. If you want to unhidden that folder then, just reverse this process in order to unhidden.
Through above ways, you can easily hide your folder. I hope you like…
As we know that in Linux (like Ubuntu, Fedora etc.) operating system, we can protect our document files (like word files, excel (database) files, presentation files etc.) easily due to Linux is highly secured, multi-tasking, multi-user operating system. In Linux, we can easily protect our document files with the help of password. It’s really useful or we can say that helpful in multi-user facility in-order to access. So, here the question is- how we can protect our document files when we are using windows operating system? Is there any way? Then, the answer is yes. In windows operating system, we can also protect our Microsoft Office document files easily with the help of password. But, note that- you can only give password in Microsoft Office 2003. You couldn’t give password in MS Office 2007 or latest.
So, in order to protect your MS Office document files via password as firstly open your document’s file (Word file or Excel file or PowerPoint file etc.). Then, write in your file (what do you want? based on your need) and after completed, just save it (Ctrl+S).
Now, the main step is how to give password in it? So, in order to give password in document files (MS Office 2003), first go to- Tools (ALT+T) and then, Click on options. After Click, you would get options wizard as then, Click on security and there enter your password (based on you).
There are two password fields are present as one is for password to open file and second for password to modify file. If you don’t know second password then, you can only open file in read mode (file only to read) and if you also don’t know first password then, you can’t open file. There are some more extra things are present (on options security wizard) in order to secure your document as based on you. Finally, click on Ok button and your settings would remain. You can also remove that passwords as all you need is to again go to- Options Security Wizard and there delete that passwords and Click on Ok button. Now, your passwords are removed. You can delete first or second or both passwords.
Now, your file is protected as open it via passwords as-
SEO stands for Search Engine Optimization. It is the process or we can say that a way to increase web-site (web-pages) traffic. It is very long and unique process but, provides good result. If you are thinking to create and publish a web-site then, it is also important for you to learn SEO in order to increase that web-site visiting. If you are owner of a web-site and your web-site visiting is very low then, all you need is learn SEO tricks in order to increase traffic to get success.
Search Engine Optimization (SEO) is the fine art of driving web traffic to web sites. Some web sites depend on general traffic as these businesses need hundreds of thousands or millions of hits per day to prosper and thrive. Other web businesses are looking for high-quality, targeting traffic. This traffic is essentially like a pre-qualified sales prospect: already interested and able to buy your product.
SEO is long but, easy process to do. SEO is generally divided into two parts-
1. On-page Optimization
2. Off-page Optimization

In Windows Operating System, you can easily hide all disk partitions or selected partitions. In order to do hide, all you need is to learn some simple commands. You can hide any partition (based on you) with the help of command prompt. As in this tutorial, I am using Windows XP operating system for this process. So in order to hide disk partitions, just go to: Start Menu and click on Run for Run Wizard. Then, type in Run wizard- “cmd” and click on “OK” button as you would get command prompt wizard. In order to get command wizard, you need to do as-
Now in command prompt, type- “diskpart” and press ‘enter’ key as after this you will be in disk partitions. Then, type “list volume” and press ‘enter key’ from your key-board as through this command, you will get the list of all partitions which are created in your hard disk. With the help of “list volume”, you will get full details of each partition as what is its real size, which letter is assigned to it, what are its volume (volume number) and many more.
Now the next step is to select your desired partition (which you want to hide) with the help of command- “select volume letter or number”. Use of ‘select’ command is the way to select particular partition and with ‘select’ command, you also need to type- volume and number or letter (which is assigned to that partition). If you are confused as how to select then, just visit the images below-
In this way, you can select a particular partition. Now, use ‘remove’ command in order to hide that partition. Type, “remove letter E” in order to remove ‘E’ letter partition. You can hide any partition based on letter which is assigned to that partition. After removed, press 'exit' from your keyboard in command prompt (to leave diskpart). You can check in "My computer" as partition is removed.
Through above process, you can easily hide any partition in your computer. Now, if you want to unhide (show) partition then, all you need is to replace as use ‘assign’ command instead of ‘replace’ command in order to unhide any partition. Note that- use ‘select’ command as “select volume number”. After it, type “assign letter E” in order to unhide (show) ‘E’ letter partition. You can unhide any partition based on letter which is assigned to that partition. After assigned, press 'exit' from your keyboard in command prompt (to leave diskpart). You can check in "My computer" as partition is unhided.
Some more commands for different tasks for disk part (partitions) as-

Through above ways, you can hide and/or unhide any partitions or all partitions of your hard disk. I hope you like…

What is Operating System?
Any hardware when manufactured in company is of not much use by itself. We need a software to drive it. A software to tell it what to do. This same applies to the computer as a whole. Computer is basically combination of input output devices, memory and CPU. We need BIOS (Basic Input Output Software) to turn on the computer. Once BIOS is loaded it looks for operating system installed in computer. Operating system is like just another software, but it controls the computer. Operating system tells computer what to do and how to do it. It has hardware drivers to access various hardwares such as HDD (Hard Disk Drive) or printer.
Operating system’s core is called a kernel. Kernel is bridge between application softwares and hardwares. On top of Kernel there is hardware drivers, system software and then application softwares. While the computer is running; operating system loads a small piece of itself into the memory and most of the time it carries out the data processing and decision making from memory only. Sometimes it writes data to hard disk - this concept in detail known as virtual memory.
Among many; some major tasks of operating system to be listed are task scheduling, resource allocation and common services for applications programs etc. At a given time period there are many tasks running in computer. Someone need to decide the priority and resource allocation for those task. Operating system does it by using many algorithms among which time scheduling is common one. When an application software needs to access one of Input / Output device it requests it to the operating system and then operating system in turn does the job of accessing that device. Example of some modern operating systems are Linux, BSD, Windows, Mac OS and Android.
Top Three Operating Systems
1. Ubuntu
Ubuntu is a GNU/Linux based open source operating system created and supported by Canonical Inc. Ubuntu is an African Bantu word which nearly means “Humanity towards others". It was launched in 20 October 2004. Ubuntu is based on Debian package management system and uses Unity Shell interface in their latest versions of operating system. Unity is based upon GTK3 framework. In past Unity was meant for Ubuntu Netbook Edition. Later it was taken as Ubuntu’s main GUI shell. But we can install Gnome3, KDE or dozens of other desktop environment or window manager as we like. Ubuntu is based on another GNU/Linux distribution known as Debian.
The main and biggest USP (Unique Selling Point) of Ubuntu is its community and support. Ubuntu was the first Linux distribution to offer commercial support on desktop Linux version. Ubuntu is free to download, install, use, modify and pass on to friends or to customers. According to Mark Shuttleworth the creator of Ubuntu, Ubuntu Operating System is the most widely used Linux distribution in the world. Ubuntu comes in various flavors. Official flavors include Kubuntu, Xubuntu and Lubuntu. There are so many unofficial flavors too some of them are Backtrack - a security distribution, Linux Mint etc.
Mac Operating system is developed by Apple Inc. Mac OS is based on Mach kernel and NextStep operating system. Apple was founded by Steve Jobs. Mac OS is closed source with some open source and BSD components. It is based on UNIX principles and technology. Mac OS is knows for popularizing graphical user interface. Mac OS from the beginning tried to minimize user work and increase performance. Mac offers graphical menu even at low level. Mac makes use of copyrighted ROM to achieve this.
Mac OS initially only supported Motorola and PowerPC platforms. With version 10 codenamed Lion Mac OS supports Intel Microprocessor family too. MacOS ships with their own hardware only. When we buy PC we buy hardware from one company and software from another company. That is not same with mac. Mac is more popular among all types of artists. Mac OS is compatible with Windows. You can transfer and edit windows documents and settings. Many mainstream softwares and games such as Microsoft office, Adobe Suit, Age of Empires are also available for Apple Mac OS too. Apple provides a great and reliable ecosystem for developers so that they can develop a core foundation of their software and port it on all Apple products.
Microsoft Windows operating system is an closed source proprietary operating system created my Microsoft Corporation, USA. You have to purchase license in order to use windows operating system. You can also buy preinstalled windows in laptops or computers. Microsoft Windows uses a controversial hybrid kernel type in all of their products. Windows was started with Windows version 1.0 and the current stable version is Windows 7. Windows was basically knows for its graphical user interface which gave it fame and major market share back in Windows 95 days.
Windows is many times criticized of using monopolistic misbehavior such as implementation of Digital Rights Management or driver signing and not fixing bug and security holes in time. Windows was created by Bill Gates when he was student. Later he left the education in order to earn money by selling windows operating system. Windows today is knows as patent troll in the computer industry.
Irrespective of all this negative points windows keeps dominating the desktop computer market today. Windows is praised and liked by common day to day user for their graphical interface and easy to user applications. Linux and Mac OS are strong competitor to Windows OS in coming future.
Finally, these above top three operating systems are most popular and mostly used operating systems...

HTML is Hypertext Mark-up Language and was composed (invented) by Tim Berners
Lee (born on 8 June 1955, a British computer scientist, MIT professor and the
inventor of the World Wide Web) in 1990. Hypertext Mark-up Language (HTML) is
commonly used to create a web-site means language for describing web-pages.
HTML is not a programming language as a simple, unique mark-up language
commonly used to develop web-pages in systematic manner. But, the question is
what mark-up language is? Mark-up language is considered as a set of mark-up
tags and HTML uses such mark-up tags to distinguish web-pages. Such mark-up
tags are commonly called HTML tags.
Now, the question is what are HTML tags? HTML tags are nothing as it
considered as keywords which are surrounded by angle brackets and normally HTML
tags comes in pairs similar like this - shown in below image. Different HTML tags are used for
different processes as for example if you want to bold a sentence or word then,
you will use bold pair and in
between you will write your sentence or word. In other words, tags comes in
pairs as first tag for start tag and second one for end tag. Start and End tags
also known as opening and closing tags.
There are number
of tags in HTML and we can combine many other languages like CSS (cascade style
sheet), Java script etc to create dynamic unique web-page.
All browsers
like Mozilla, Chrome, and Internet Explorer etc read HTML documents and display
them as web-pages or we can say that a web-site. So, what are HTML documents?
HTML documents are those documents which contain HTML tags and plain text as to
describe web-pages and those HTML documents are also called Web-pages. Browsers
does not show the HTML tags but, use HTML tags due to interpret with the
content of the page. The Following is the way to write code in HTML way-
In this way, you can write your code. Finally,
Hyper-text Markup Language (HTML) is the first step in internet means priory used
first language to create web-pages or web-site and known as common language for internet...
It is depends up on your computer and on your compiler about the process of compiling your program varies. For now, we will suppose that you are using a WINDOWS machine and in windows, you are using the turbo C compiler.
So here is the program code to see string “Hello World” on your output screen:
To run your program, simply press CTRL + F9 key. You would see the following output:
Hello World
To debugging your program line-wise then, press F7.
After this we can save our program as hello.cpp where .cpp shows c++ program file.
Let’s take a look at each line of code that makes up hello.cpp.
#include iostream.h
The effect of this line is to essentially "copy and paste" the entire file iostream.h into your own file at this line. So you can think of this syntax as replacing the line #include with the contents of the file iostream.h. #include is known as a preprocessor directive, which will be covered much later. This file is located somewhere in your include path. The include path indicates the directories on your computer in which to search for a file, if the file is not located in the current directory. In this case, iostream.h is a file containing code for input/output operations. You need to include iostream.h so that the compiler knows about the word cout cin, which appears a couple of lines below.
int main()
Every C++ program must have what is known as a main function. When you run the program, the program will go through every line of code in the main function and execute it. If your main is empty, then your program will do nothing. There are essentially four parts to a function definition. They are the return type, the function name, the parameter list, and the function body, in that order. In this case:
This is the line that prints out the text string, "Hello, World!". For now, don't worry about how cout works; just know how to use it. You can print out any series of text strings. So, write cout<<"Hello, World!";
Cin works as to scan those text strings. The cout and cin functions are system defined functions used to print the words and scan those words means cin used as input and cout as output.
return 0;
This line is necessary because the return type of main is int (see above). We'll talk more about functions and return types later, but for now understand that because the function's return type is int, the function must return an int (integer). To return 0 (which is an integer, we simply write return 0;.
getch();
getch(); is used to hold output screen as if we compiled our program then, black screen will appear and then, we will easily see our result. Without this, we will press Alt+f5 to visit our output screen. So this is better that once we entered once in our code getch(); and with this, it is compulsory to add #include in our program which shown above in our program.
Finally, these above concepts are the c++ program code lines concepts and all are described well...

Commonly we all know that electricity is very important in this era. This is basic need of human. We all know that powering your life with sun energy is clean, efficient and less expensive than coal-powered electricity. Nowadays, you can see solar panels in many places like- on homes, businesses, and even traffic signals. Solar panels are designed and engineered to capture the most ultraviolet light to convert into electricity. A solar Panel is a connected crew of Solar cells. It is also known as photovoltaic cells.
As we become more concerned with the environment we have begun research on alternative sources of energy. One such source that is gaining traction is solar power. Solar light can be harnessed in various ways, but the main use on a residential level is in the form of solar cells to generate electricity. Electricity is formed by the movement of electrons apart two plates that can be made from silicon, or various other materials. Crystal silicon is very expensive to make and thus there are various quality levels of solar panels with various efficiency and cost factors.
Three types of Solar Panels
1. The most expensive as one of the most efficient residential type is Mono-crystalline panels. It allows for up to 25% efficiency and can be used to produce a large portion of a house’s energy needs as well in some areas selling back to the power companies for profit.
2. The next best type of panel is poly-crystalline panels. As the name implies, this panel is made up as multiple crystals which can be seen directly on panels. It can be described as a Mono-crystalline panel that has been severely cracked. Because of this, efficiency for these panels is not as good, but since they basically use the scraps of Mono-crystalline panels, they are cheaper to purchase.
3. A third type of panel is amorphous solar cells, or thin film. Often this is put into a paint that can be coated on a surface. Since the crystal saturation is far less than the other two panels, this method is by far the least efficient, but because of how much silicon is used and how relatively easy it is to make, it is the cheapest solution.
Solar cells will continue to advance and come down in price. This is a necessity because currently solar homes add a significant price to a home which causes many people to not want to spend the extra money. Finally, Solar Panel importance is increasing day by day...
