What's in a name?
The name Joomla! is a phonetic spelling for the Swahili word "Jumla", which means "all together" or "as a whole". It was chosen as the entire team behind Mambo was unanimous in their commitment to protecting the interests of the project and community.
This name was chosen from thousands of recommendations by the community, and even went through an arduous review session by branding and marketing professionals who also felt that Joomla! was the best choice of the lot.
What sets Joomla! apart from the rest is our dedication to keeping things as simple as possible while providing the most features possible. Finally, non-technical people can have complete control over their websites without paying exorbitant amounts for closed, proprietary software.
Joomla! is more than just software, it is people. The community behind Joomla! includes developers, designers, systems administrators, translators, content writers, and most importantly the end users. We welcome you to our community, and look forward to the future with great excitement!
any people know from their own experience that it's not easy to install an Apache web server and it gets harder if you want to add MySQL, PHP and Perl. XAMPP is an easy to install Apache distribution containing MySQL, PHP and Perl. XAMPP is really very easy to install and to use just download, extract, and start.
HOW TO INSTALL XAMPP.....
After the installation is complete, you will find XAMPP under Start | Programs | XAMPP. You can use the XAMPP Control Panel to start/stop all server and also install/uninstall services.
The XAMPP control panel for start/stop Apache, MySQL, FilaZilla & Mercury or install these server as services.

in the same drive u create a text file and type
ren movies movies.{21EC2020-3AEA-1069-A2DD-08002B30309D}
and save it as loc.bat
again u type in a notepad as
ren movies.{21EC2020-3AEA-1069-A2DD-08002B30309D} movies
and save it as key.bat
now in D drive u can see two batch files loc and key.. when u double click loc the movie folder will change to control panel and whn u double click key the control panel will change to normal folder..
Try this out .....
It may be secure ur personal data......try n follow my blog......
When you type in MS-DOS commands, your drive letter is shown on the command line. You can log on the A: drive (have the A: drive as your prompt) or on to any valid drive by just typing in the drive letter followed by a colon and then pressing Enter. When you log on to a drive, all your commands will be executed on that drive - unless you specify otherwise.
Here are the steps:
1. Put a floppy disk into your machine.
2. Open an MS-DOS window. You will be at the C:\> prompt (you may be inside a directory structure, but you will be on the C: drive)
3. At the prompt, type in A: and press Enter.
4. Do a DIR to prove you are now on a blank drive (a drive with no files on it).
♥ Making A Directory (using MKDIR or MD)
The way you make directories on a disk drive is to use the MKDIR command. The MKDIR command has a shortened form called MD and you can use either command interchangeably. For our examples, we will use MKDIR since that command is standard in at least one other operating system (Unix).
For this exercise, we will make a directory called FREEDOM on our floppy diskette. Which we will use in follow-on exercises. To make the directory, do the following:
1. Put your floppy disk into the computer.
2. Go to MS-DOS and log into the A: drive.
3. Using the MKDIR command, make a directory called FREEDOM. The syntax will be: MKDIR FREEDOM
(be sure you are on the A: drive when you use the command!)
♥Changing Directories (using CHDIR or CD)
Directories are containers that are made to hold your files in a nice orderly way. To get to those directories and to see the files in them, you would use a combination of the CHDIR (or CD) commands and the DIR command. Do the following exercise to see how the CHDIR (or CD) command is used.
1. Put your floppy disk in the drive (be sure you have completed the previous MKDIR task)
2. Go to the MS-DOS prompt and log on to the A: drive.
3. Use the CHDIR command to enter the FREEDOM directory that you made previously. (CD FREEDOM)
4. Use the DIR command to see that there are no files in the directory. (only the . and .. files and those are for MS-DOS internal use).
5. Using the EDIT command, make two files. Call the first one AAA.TXT and the second one B.TXT.
6. Exit the EDIT program and do a DIR of the directory so you can see the files you just made.
7. Use the CHDIR command to get back to the root of the A: drive. ('CD \' is the command!)
☻ Important Shortcuts To Remember:
To change to the ROOT directory from any directory or subdirectory type:
CHDIR \ {ENTER}
To change to the parent directory of your current directory type:
CHDIR .. {ENTER}
♥ Adding Parameters to a command
A parameter is a letter typed after a command, that tells the command to carry out an extra task. These parameters are also called 'switches'.
For instance, a command that you've already used is the DIR command. The command with a parameter might look like this:
DIR /S /P
( The /S and the /P are the parameters. You can use either one.)
This Part
Tell MS-DOS to
DIR
Show the files and directories in the current directory ...
/S
.. and show all the files and directories below this directory (recurse )
/P
.. and show them one page at a time, waiting for the user to press 'Enter' between pages.
Most parameters are optional, however you will discover, over time, ones that you use frequently.
Go to the DOS prompt now and, with your diskette in drive A: do the following:
1. Log on to the A: drive
2. Do a DIR command
3. Do a DIR /S command and note the difference
♥ Copying Files (first look)
When you COPY a file, you make an exact duplicate of it. However, no two files in the same directory may have the same name. So you must either COPY the file to another directory, or copy it to another file name. We will look at copying files to another directory in a later lesson, but for this lesson, we want to make some copies of the files we created earlier on our floppy diskette and we want to keep all the files in the same directory called A:\FREEDOM. That means we will have to copy the files to different file names.
We want the following files in our A:\FREEDOM directory: A.DOC; AA.DOC; AAA.TXT; B.DOC; A.TXT; B.TXT. We will use them in the next lesson. Since it doesn't matter what's inside the files for our lesson, we will just copy one of the files we already made to the new filenames.
Do the following exercise:
1. Put your floppy disk in drive A:
2. Go to the MS-DOS prompt and log onto Drive A:
3. Go to the FREEDOM directory
4. In this directory, you already have AAA.TXT and B.TXT. Do the following COPY commands:
COPY AAA.TXT A.DOC
COPY AAA.TXT AA.DOC
COPY AAA.TXT B.DOC
COPY AAA.TXT A.TXT
5. Do a DIR to see the result
♥ Formatting a Diskette (review)
DANGER: BE SURE YOU ONLY FORMAT FLOPPIES! NEVER FORMAT YOUR C: DRIVE WHEN DOING THESE LESSONS ELSE YOU WILL LOSE EVERYTHING ON YOUR HARD DRIVE!!
You use the FORMAT command to format a diskette. We did that in our previous lesson.
Formatting a diskette you have previously used erases any data on the diskette, so only reformat a diskette if you are very sure you don't need any of the data on it.
1.Type:
FORMAT A: {ENTER}
Note: To put the MS-DOS operating system files onto the diskette you are formatting, add the /S switch to the command
FORMAT A: /S {ENTER}
Putting the operating system on the diskette enables you to BOOT-UP the computer from the diskette. This disk is now known as a SYSTEM DISK.
NOTE THAT THIS COMMAND DOESN'T WORK ON WINDOWS 2000 or XP!!! The Windows 2000 or XP operating system is too big to fit on a diskette.
2. When this prompt appears on the screen.
Insert new diskette for drive A: and strike ENTER when ready
insert the diskette you want to format into drive A:
Press the {Carriage Return } or { ENTER } key.
3. When formatting is complete, and this prompt appears:
Format another (Y/N) ?
Type Y (for yes) to format another diskette, N (for no) to exit from the FORMAT command
♥ Checking the Condition of a Disk
You use the CHKDSK command to:
• Check a disk to see how much space there is available, and how much is in use.
• Fix some disk errors, such as files that show a non-zero size but that really have no data in them
• Display information about the disk, including the total disk space, the number and size of files.
The command:
CHKDSK A: /F {ENTER}
Checks the disk in drive A: for errors and fixes any errors it can. If CHKDSK finds no errors it displays a report like this:
C:\>chkdsk A: /F
The type of the file system is FAT.
Volume Serial Number is 11EC-3150
Windows is verifying files and folders...
File and folder verification is complete.
Windows has checked the file system and found no problem.
1,457,664 bytes total disk space.
512 bytes in 1 folders.
3,072 bytes in 6 files.
1,454,080 bytes available on disk.
512 bytes in each allocation unit.
2,847 total allocation units on disk.
2,840 allocation units available on disk.
C:\>
If the CHKDSK command reports any errors on the disk, it displays a message such as:
xxx lost clusters found in xxx chains
and asks you whether you want to correct the errors.
Type Y (for yes) and then press the {ENTER} key.
NOTE:-This procedure can cause you to lose some of the information on your disk, however, not fixing the disk can cause you to lose even more!!
C language is the primary language of the computer system developed between 1969 and 1973 by Dennis Ritchie at Bell Telephone Laboratories. The initial development of ‘C’ occurred in AT&T Bell Laboratories. In 1978 Brain Kernighan and Ritchie published a definitive description of the language referred to as K & R version of C. Numerous C compilers and interpreters had been written for different Operating systems. This created some minor incompatibilities among different implementations of the language. Therefore, the ANSI (American National Standard Institute) worked on a standard version of C language.
C has different data types for different types of data and can be broadly classified as: 1. Primary data types 2. Secondary data types These data types are illustrated in the Picture…
C is an all purpose programming language. It is equally suitable for generating high level application and low level application. C language encourages the users to write their own library function so that they can extend the features of the language and C program can be executed on any type of computers. The program written in C language can be converted into machine language more efficiently. Computer games can be generated in C language which is accomplished through the usage of sound graphics. Both low and high level programming can be done in C language. C language is the address manipulation which can be done through the usage of pointers. C software is usually known as “turbo3”. C is simple, fast, and efficient, the first stage for a programmer. Finally, C is close to hardware.
Why we use C firstly? In today’s world of computer programming, there are many high-level languages to choose from, such as Pascal, BASIC, and Java. But C stands apart from all these languages. This is due to its many desirable qualities. It is a robust language whose rich set of built-in functions and operators can be used to write any complex logic program. The C language compiler combines the capabilities of a low level language with the features of a high level language. Therefore the language is suitable for writing both system software as well as business packages & other software. You will many compilers available in the market written in C.
The general way to write program in ‘C’ as- #include #include void main () { printf (“Hello”); getch(); } Here, output will- Hello
In this way, programs are written in “C”. Programs are of many types in ‘C’ as switch case programs, pointer programs, array programs, using functions programs etc. All have different uses on different places.
Finally, C is the primary basic language of Computer System…
ronounced yoo-niks, a popular multi-user, multi-tasking operating system developed in the 1960s at the bell laboratory. Created by just a handful of programmers, UNIX was designed to be a small, flexible system used exclusively by programmers. UNIX is a highly programmable language (an operating system) and still regarded as one of the most powerful, versatile, and flexible operating system (OS) in the computer world. UNIX Systems have Graphical User Interface (GUI) facility like Microsoft Windows which to easy to use. The most famous varieties of UNIX are Sun Solaris, GNU/Linux, and MacOS X.
It was designed for a programmer not for a casual end-user. A programmer can easily operate UNIX operating system.
Multi-tasking Facility
Many computers do just only one thing at a time, as anyone who uses a PC or laptop can attest. But, on the other hand, UNIX lets a computer do several things at once, such as printing out one file while the user edits another file. This is a major feature for users, since users don’t have to wait for one application to end before starting another one.
Multi-user Facility
The computer can take the commands of a number of users, determined by the design of the computer to run programs, access files, and print documents at the same time. This is the best facility of UNIX.
It has fast speed with respect to others and it is mainly divided in three parts as follows-
1. The Kernel
2. The shell and
3. The programs.
The Kernel
It controls the hardware and turns part of the system on and off at the programmer’s command. If you ask the computer to list all the files in a directory then, the kernel tells the computer to read all the files in that directory from the disk and display them on your screen. The Shell
Shell is used to act as an interpreter between the user and the computer as its purpose is same like Kernel. There are several types of shell as most notably the command driven Bourne Shell, the C Shell (no pun intended), and menu-driven shells that make it easier for beginners to use. The Programs
There are hundreds of programs available to UNIX users. Typically, they are grouped into categories for certain functions, such as word processing, business applications, or programming.
The main features of UNIX are
Multitasking capability
Multiuser capability
Portability
UNIX programs
Library of application software
Finally, UNIX is the best operating system, very admired as today it is using by billions of peoples…
