இன்டர்நெட்டில் "WWW" என்றால் என்ன?

இன்டர்நெட் இல்லை என்றால் பூமியே சுத்தாது என்று சொல்லும் அளவிற்கு அசுர வளர்ச்சி பெற்று விட்டது.இன்றைய இளைஞர்கள் முதல் பெரியவர்கள் வரை எதற்கெடுத்தாலும் இன்டர்நெட் தான், அதுவும் சமூக வலைத்தளங்கள் பற்றி சொல்லவே வேண்டாம்.

பிரிட்டிஷ் கணினி விஞ்ஞானியும், முன்னாள் செர்ன்(CERN) ஊழியருமான டிம் பெர்னர்ஸ் லீ மற்றும் பெல்ஜிய கணனி விஞ்ஞானி ராபர்ட் கயில்லியவ் இவர்கள் தான் இணையத்தை கண்டுபிடித்தவர்களாக கருதப்படுகிறது.

1989ம் ஆண்டில் டிம் பெர்னர்ஸ் லீ உலகளாவிய வலைக்கு முதல் கட்ட திட்ட அமைப்பை எழுதினார். இது முதலில் செர்ன்(CERN) தகவல் பறிமாற்றத்திற்காக மட்டுமே எழுதப்பட்டது.

ஆனால் இது உலகளவில் சென்றடைய வேண்டும் என்பதை உணர்ந்த பெர்னர்ஸ், 1990ல் ராபர்ட் உடன் இணைந்து மேம்படுத்தப்பட்ட உலகளாவிய வலையமைப்பை உருவாக்கினார்.

இணையம்(Internet) மற்றும் உலகளாவிய வலை(WWW) ஆகிய சொற்கள் பேச்சு வழக்கில் பெரிதும் வேறுபாடின்றி அடிக்கடி பயன்படுத்தப்படுகின்றன.

இருப்பினும், இணையமும் உலகளாவிய வலையும் ஒன்றல்ல.

இணையம் என்பது உலகளாவிய தரவுத் தகவல்தொடர்பு முறைமையாகும். வலை என்பது இணையத்தின் வழியாகத் தொடர்புகொள்ளும் சேவைகளில் ஒன்றாகும்.

இது மிகை இணைப்புகள் மற்றும் URLகள் மூலம் ஒன்றுடன் ஒன்று இணைக்கப்பட்ட ஆவணங்கள் மற்றும் பிற வளங்களின் தொகுப்பாகும். சுருக்கமாக, வலை என்பது இணையத்தில் இயங்கும் ஒரு பயன்பாடு என்றே சொல்லலாம்.

Krish Infotech Cuddalore: Windows 7 Tips

Have you ever wondered just how some people really get, what seems like, full use of their computer?  Sure we all played Minesweeper and wrote the occasional Word document when we first started out using computers.  Nowadays computers are a regular part of everyday life.  From playing games to communicating with friends and family half way around the globe. Computers are really useful tools, but, all tools can be used in different ways. Here’s a quick top 10 count down on a few tips and info that’ll make your life easier in Windows 7. 

10. GOD MODE:

To give you complete control over all the configurable options in Windows at a single press of a button just simply create a new folder anywhere and rename it to this: GodMode.{ED7BA470-8E54-465E-825C-99712043E01C} The folder you create will now have 270 items that are to do with configurable options in Windows 7. Interestingly it also works for Windows 8.1 as well.

9. “VIRTUAL” WI-FI:

Windows 7 has a Microsoft Virtual Wi-Fi Miniport adapter located in your network connections. You can use this for making your laptop work as a Wi-Fi hotspot.

8. RELIABILITY MONITOR:

If your computer is being a little strange or if it isn’t doing something it should, or for that matter, is doing something that it shouldn’t then search for ‘reliability’ in the Start menu and open the ‘View reliability history’. This will display a graph of the system’s stability index with the scale 1-10 for a certain period of days or weeks. This should allow you to figure out which program or Windows component is not working as it should.

7. ENHANCED CALCULATOR:

Calculators are great for standard mathematics, but what if you need a to shake things up a little in the science dept? If you click the view menu, you will see that the calculator comes equipped with a number of powerful built-in features; unit conversions, mortgage spreadsheets, date calculations and fuel mileage, etc. Not so standard now, are you?

6. STEPS RECORDER:

If you need remote assistance but the remote access is not working, just search and run “psr” from the Start menu. When you click on the “Start Record” option, the feature starts recording all the activities by an array of screenshots while adding automatic captions. When you end recording, all the recorded data is combined together and then saved as a web browser-compatible MHTML (MIME HTML) file which is kindly pre-zipped and ready to be attached to an email for you to send to your helper.

5. FILE SUPPORT IN WORDPAD:

WordPad can now open ODT or DOCX files. The only downside is that it doesn’t work great with all formatted docs.

4. POWER EFFICIENCY REPORT:

From the Start menu, navigate to CMD and type the following:

powercfg –energy

This will then scan your system for 60 seconds, then a file named energy-report.html will be created in \windows\system32 folder. Just copy it somewhere else before opening it, i.e. your desktop, and it will reveal which settings or devices are zapping power.

3. ERASE FREE DISK SPACE:

When you delete something in Windows, the space they had taken up is labeled as “available for use.” But, the deleted files are still restorable if you use some software until they are overwritten with more data. To resolve this simply, open Command Prompt and type:

cipher /w:Z

Replace Z with the letter of the drive/partition you wish to erase. Be patient, it takes time.

2. FOLDERS ON YOUR TASKBAR:

Programs can be pinned to the task bar and are useful there, right? This is how you can keep the folders. Just drag a folder to the empty space on the Taskbar and then release the button once the “Pin to Windows Explorer” pops up. Now every time you right click the Windows Explorer button, you will have access to the folder via Jump List.

1. HOTKEY WINDOWS BETWEEN MONITORS:

To do this, just hold onto the Windows key and press left or right arrow and your active window will then be anchored in that direction. This happens on every monitor that you have and if you use Windows + Shift +Left/Right Arrow key, the active window will jump to the second monitor.

So there you have it, a few tips to keep you occupied for a while. Enjoy.

Have you ever wondered how can you make your computer speak whatever you input to it like in the movies? Would it not be fun? If only it was possible! Rejoice, because now it is possible. Well, if you wish to know how to do this, then you have come to the right place. With this trick, you can create a script in Windows which will make your computer speak whatever you input to it.

To create one such talk script, follow the steps given below:-

Steps
1) Open Notepad.
2) Copy and paste the exact code given below.

          Dim Message, Speak
          Message=InputBox("Enter text","Speak")
          Set Speak=CreateObject("sapi.spvoice")
          Speak.Speak Message

3) Click on File Menu, Save As, select All Types in Save as Type option, and save the file as Speak.vbs or "*.vbs".

Windows Compatibility: This VBS file can be executed on all versions of Windows including Windows XP, Windows Vista, Windows 7 and Windows 8.


(or by another method)

Step 1: Open Notepad

Open up Notepad on your windows xp, windows 7, or windows 8 computer.

Step 2: The Code

Type this into Notepad:

Dim text, sapi
text=inputbox("enter text to be spoken")
Set sapi=Createobject("sapi.spvoice")
sapi.Speak text

Now what does this mean?
-When you execute this script it first creates a input box which is recognized as "text". 
-Then the script sets up the sapi so we can now use it (this what will speak)
-Lastly it takes what was typed into input box "text" and sends it to the sapi to be spoken. 

Step 3: Save Your File

Now you need to save your file. 

First Click file>save as...

Next choose any file name but be sure to put .vbs afterwards. Ex. Filename.vbs

Then be sure to click next to Save as type: and then in the drop down menu click All Files

Click save.

Step 4: Execute Your File

The last step is to locate where you saved your file and double click it.

In the input field enter something and click ok.

Congratulations! You just made your computer talk!

Other notes:
• this is written in a Visual Basic scripting language (vbs)
• this only works with windows xp and higher
• if your having trouble or have questions feel free to ask me in the comments.

Cuddalore Krish Infotech: Parts of a computer

If you use a desktop computer, you might already know that there isn't any single part called the "computer." A computer is really a system of many parts working together. The physical parts, which you can see and touch, are collectively called hardware. (Software, on the other hand, refers to the instructions, or programs, that tell the hardware what to do.)

The following illustration shows the most common hardware in a desktop computer system. Your system might look a little different, but it probably has most of these parts. A laptop computer has similar parts but combines them into a single, notebook-sized package.

System unit

The system unit is the core of a computer system. Usually it's a rectangular box placed on or underneath your desk. Inside this box are many electronic components that process information. The most important of these components is the central processing unit (CPU), or microprocessor, which acts as the "brain" of your computer. Another component is random access memory (RAM), which temporarily stores information that the CPU uses while the computer is on. The information stored in RAM is erased when the computer is turned off.

Almost every other part of your computer connects to the system unit using cables. The cables plug into specific ports (openings), typically on the back of the system unit. Hardware that is not part of the system unit is sometimes called a peripheral device or device.

Storage

Your computer has one or more disk drives—devices that store information on a metal or plastic disk. The disk preserves the information even when your computer is turned off.

Hard disk drive

Your computer's hard disk drive stores information on a hard disk—a rigid platter or stack of platters with a magnetic surface. Because hard disks can hold massive amounts of information, they usually serve as your computer's primary means of storage, holding almost all of your programs and files. The hard disk drive is normally located inside the system unit.

CD and DVD drives

Nearly all computers today come equipped with a CD or DVD drive, usually located on the front of the system unit. CD drives use lasers to read (retrieve) data from a CD; many CD drives can also write (record) data onto CDs. If you have a recordable disk drive, you can store copies of your files on blank CDs. You can also use a CD drive to play music CDs on your computer.

CD

DVD drives can do everything that CD drives can, plus read DVDs. If you have a DVD drive, you can watch movies on your computer. Many DVD drives can record data onto blank DVDs.

Tip

If you have a recordable CD or DVD drive, periodically back up (copy) your important files to CDs or DVDs. That way, if your hard disk ever fails, you won't lose your data.

Floppy disk drive

Floppy disk drives store information on floppy disks, also called floppies or diskettes. Compared to CDs and DVDs, floppy disks can store only a small amount of data. They also retrieve information more slowly and are more prone to damage. For these reasons, floppy disk drives are less popular than they used to be, although some computers still include them.

Why are these disks called "floppy" disks? The outside is made of hard plastic, but that's just the sleeve. The disk inside is made of a thin, flexible vinyl material.

Mouse

A mouse is a small device used to point to and select items on your computer screen. Although mice come in many shapes, the typical mouse does look a bit like an actual mouse. It's small, oblong, and connected to the system unit by a long wire that resembles a tail. Some newer mice are wireless.

A mouse usually has two buttons: A primary button (usually the left button) and a secondary button. Many mice also have a wheel between the two buttons, which allows you to scroll smoothly through screens of information.

Mouse pointers

When you move the mouse with your hand, a pointer on your screen moves in the same direction. (The pointer's appearance might change depending on where it's positioned on your screen.) When you want to select an item, you point to the item and then click (press and release) the primary button. Pointing and clicking with your mouse is the main way to interact with your computer. For more information, see Using your mouse.

Keyboard

A keyboard is used mainly for typing text into your computer. Like the keyboard on a typewriter, it has keys for letters and numbers, but it also has special keys:

The function keys, found on the top row, perform different functions depending on where they are used. The numeric keypad, located on the right side of most keyboards, allows you to enter numbers quickly. The navigation keys, such as the arrow keys, allow you to move your position within a document or webpage.

You can also use your keyboard to perform many of the same tasks you can perform with a mouse. For more information, see Using your keyboard.

Monitor

A monitor displays information in visual form, using text and graphics. The portion of the monitor that displays the information is called the screen. Like a television screen, a computer screen can show still or moving pictures.

There are two basic types of monitors: CRT (cathode ray tube) monitors and the newer LCD (liquid crystal display) monitors. Both types produce sharp images, but LCD monitors have the advantage of being much thinner and lighter.

Printer

A printer transfers data from a computer onto paper. You don't need a printer to use your computer, but having one allows you to print e‑mail, cards, invitations, announcements, and other material. Many people also like being able to print their own photos at home.

The two main types of printers are inkjet printers and laser printers. Inkjet printers are the most popular printers for the home. They can print in black and white or in full color and can produce high-quality photographs when used with special paper. Laser printers are faster and generally better able to handle heavy use.

Speakers

Speakers are used to play sound. They can be built into the system unit or connected with cables. Speakers allow you to listen to music and hear sound effects from your computer.

Modem

To connect your computer to the Internet, you need a modem. A modem is a device that sends and receives computer information over a telephone line or high-speed cable. Modems are sometimes built into the system unit, but higher-speed modems are usually separate components.
