Definition :The server is a computer system that provides the kind of service particular in a computer network. The server is supported by the calable processors and large RAM, also equipped with a special operating system, called the network operating system or network operating system . The server is also running administrative software that controls access to networks and resources contained therein, as well as file or printer device (printer), and provide access to the workstation network.
Server is an important part of a network. a computer network with multiple computers requires a server that is responsible for providing services needed by the client.
1. Fax Servers
Fax servers are used to serve the fax service for the client. Given this fax server. Any demand for sending faxes and receiving faxes fax server will go through this. Fax server is also equipped with a modem that supports fax function.
2. FTP Server
This server has an FTP protocol service. This means that with the existence of this FTP server, all requests FTP (FTP is a protocol for data transfer services) will be accomplished.
3. Mail Server
Mail servers have a role to serve the client in terms of mail (letter). The letter in this case, the client can send messages to other clients, that where the letter is stored on the mail server, too. Apart from being a place to store letters, mail server also provides complementary services such as mail service web interface for easy client to write letters and organize letter dipunya client.
4. Database Server
Server database, as the name suggests. This server serves service for clients who require a database storage services. In the database server, can contain hundreds or thousands of databases from many users. Usually the database is grouped or stored per user who used the service database. To avoid the occurrence of data theft.
5. Proxy Server
Proxy servers, can be used to strengthen security on a network. This server can be used to filter incoming and outgoing service requests from a client. With the proxy server, we can block an IP in order to communicate, for example.
6. Web Servers
This server is a server that might not unusual anymore to hear. Sites such as search engines, blogs, websites etc would need a web server for a file - such as web file. Html. Php. Asp can be processed first in the web server before the fule is sent to the client. Web servers serving the service request with the HTTP protocol, and there are also IMAP or FTP.
7. Telnet Server
Is the server used to serve the Telnet service. With this server, we can do remote computer that we want. Before our computer remotely, our first entry in this telnet server login system. Then telnet requests forwarded to the destination computer that requested by the client.
8. File Server
File servers can mean the computer used to collect data - data that is owned by a number of clients. The server storage capacity also depends on the capacity of the HDD which is owned by the server.
9. Game Servers
Game server is the server used for the center to connect between the players (clients) with the other players. Game servers are in addition to a separate server, can also be established from client computers that play the game.
10. DNS Server
DNS servers have a utility for DNS service. DNS allows you to translate the domain address of a computer into a form of IP. Therefore, if we do not specify DNS servers on the IP Address setting, then we will find it hard to open sites like Google, because Google address should be translated into plain old IP address before our computers can connect to the google server .. While the dns server IP address has not been determined by us.
11. Print Server
This server can be used for printing service center (print) for the client. With the existence of this server, all the activities of "print" can be done together and save on hardware costs because although there is one printer, the printer can be used by multiple computers.
12. Application Server
In its function, this server is the computer servers used to run a software application.
13. Streaming Media Server
This server serves service streaming media data such as music, video. This service allows us to access a downloaded content without our prior.
14. Home Server
This server is a server that is specifically for home users who need services such as home entertainment. This computer can be also added other services such as printing services service, web service, or service as a backup data file. So this computer has many functions.
15. DHCP Server:
Protocol-based client / server architecture that is used to facilitate the allocation of IP addresses in one network.

Macam-Macam SERVER
Server merupakan suatu bagian terpenting dari sebuah jaringan. suatu jaringan komputer dengan banyak komputer memerlukan suatu server yang bertugas untuk menyediakan layanan yang dibutuhkan oleh client.
Server sampai saat ini memiliki beberapa macam jenis. Dari berbagai macam jenis server tersebut memiliki kegunaan dan tugasnya masing – masing. Dan setiap jenis server tersebut bisa dijadikan satu mesin. Jadi satu komputer server bisa melayani berbagai servis atau layanan.Macam – macam jenis server tersebut adalah sebagai berikut :
- Mail Server
Mail server mempunyai peran untuk melayani client dalam hal mail (surat). Surat dalam hal ini, client bisa mengirimkan pesan ke client yang lain, yang dimana surat tersebut disimpan dalam server mail itu juga. Selain sebagai tempat untuk menyimpan surat, server mail juga menyediakan layanan pelengkap mail servis seperti web interface untuk memudahkan client menulis surat dan mengorganisir surat yang dipunya client. - Database Server
Server database, seperti namanya. Server ini melayani servis bagi client yang membutuhkan layanan penyimpanan database. Dalam server database tersebut, bisa berisi ratusan ataupun ribuan database dari banyak user. Biasanya database tersebut dikelompokkan atau disimpan per user yang memakai layanan database tersebut. Agar tidak terjadinya pencurian data. - Proxy Server
Proxy server, bisa digunakan untuk memperkuat security pada sebuah jaringan. Server ini bisa digunakan untuk memfilter permintaan servis masuk maupun keluar dari sebuah client. Dengan adanya proxy server ini, kita bisa memblock suatu IP agar bisa berkomunikasi misalnya. - Web Server
Server ini merupakan server yang mungkin tidak aneh lagi didengar. Situs seperti search engine, blog, website dll pasti membutuhkan web server agar file – file web seperti .html .php .asp bisa diproses terlebih dahulu dalam web server sebelum fule tersebut dikirimkan ke client. Web server melayani request servis dengan protokol HTTP, dan ada juga IMAP ataupun FTP. - Telnet Server
Merupakan server yang digunakan untuk melayani servis Telnet. Dengan adanya server ini, kita bisa melakukan remote komputer yang kita inginkan. Sebelum kita meremote komputer, kita masuk dulu dalam sistem login server telnet ini. Kemudian permintaan telnet diteruskan ke komputer tujuan yang diminta oleh client. - File Server
File server bisa berarti komputer yang digunakan untuk menampung data – data yang dimiliki oleh sejumlah client. Kapasitas penyimpanan server tersebut juga tergantung dari kapasitas HDD yang dimiliki oleh server tersebut. - Game Server
Game server merupakan server yang digunakan untuk pusat untuk menghubungkan antar pemain (client) dengan pemain yang lainnya. Game server ini selain merupakan server tersendiri, bisa juga didirikan dari komputer client yang bermain game tersebut. - DNS Server
DNS server mempunyai kegunaan untuk servis DNS. DNS berguna untuk menerjemahkan alamat domain sebuah komputer ke dalam bentuk IP. Oleh sebab itu jika kita tidak menentukan DNS server pada settingan IP Address, maka kita akan kesulitan untuk membuka situs seperti Google, karena alamat google tersebut harus diterjemahkan dulu ke dalam bentuk IP address sebelum komputer kita bisa terkoneksi ke server google tersebut.. Sedangkan alamat IP server dns belum ditentukan oleh kita. - Print Server
Server ini bisa digunakan untuk pusat layanan percetakan (print) bagi client. Dengan adanya server ini, segala aktivitas “print” bisa dilakukan secara bersama dan menghemat biaya hardware karena meskipun terdapat satu printer, printer tersebut bisa digunakan oleh banyak komputer. - Application Server
Dalam fungsinya, server ini merupakan komputer server yang digunakan untuk menjalankan suatu software applikasi. - Streaming Media Server
Server ini melayani servis streaming data media seperti musik, video. Servis ini memungkinkan kita dapat mengakses sebuah konten tanpa kita mendownloadnya terlebih dahulu. - Home Server
Server ini merupakan server yang khusus bagi pengguna rumah yang membutuhkan layanan seperti home entertainment. Komputer ini bisa juga ditambah layanan servis lainnya seperti printing servis, web servis, maupun file servis sebagai backup data. Sehingga komputer ini memiliki berbagai fungsi.

How to Install Joomla 1.5
This tutorial quickly leads you through installing Joomla 1.5. It details both a local installation for testing (if you do not have a hosting account or have a slow internet connection) and a real web server installation.
Joomla is a complex series of PHP scripts that run on a web server. When you browse a Joomla site, these scripting are being generated on the fly and creating what you see on the pages of the site. The key words here are web server.
Running and Testing Joomla Without a Hosting Account
You cannot download Joomla and try to run it on your computer like an exe file. It has to have a web server, which means you need to have a hosting account. Sounds obvious, but I have had a couple of people if they needed windows XP to run Joomla!
Now, before we shell out our hard earned money for a hosting account, there is something else you can do first. You can actually run a web server on your local computer, in other words, your desktop or laptop. This is known as having a localhost. It may sound like I just contradicted myself from the previous paragraph, but not quite. You can’t "run" Joomla itself on your own computer, but you can install a localhost web server for it to "run on".
What you need to pull this off is some software that runs Apache, PHP and MySQL on your computer. These are the same software packages that power websites. There are two popular ones, WAMP (www.wampserver.com/en/index.php) and XAMPP (www.apachefriends.org/en/xampp.html) and they are both free (PGL license)
I am going to quickly run through setting up WAMP, not that this package is windows specific.
Download WAMP from the above link, and then install it. It will create a folder c:/wamp/www
Run WAMP, you should get a handy icon in your system tray:
You need the dial to be white to continue. Note if you run Skype, it interferes with WAMP and so you have to start WAMP without Skype running (and then start Skype if you need it)
Now open a browser and go to localhost (no "www")
You should see the following page:
If you are not seeing this then you should stop and figure out why. You have to get this page before you can proceed. The WAMP site has some helpful troubleshooting FAQ's and a forum.
You should see your folder called "Joomla" in the list of Your Projects. Click on that folder and you will get taken to that "website".
Installing a Joomla Site on a Hosting Account
So let's assume you either have a hosting account, or are going to get yourself one. There are some minimum requirements for Joomla to run, and they are slightly different for the different versions.
Here are the minimum requirements for Joomla 1.0
* PHP 4.2.x or above - www.php.net
* MySQL 3.23.x or above - www.mysql.com
* Apache 1.13.19 or above - www.apache.org
You must ensure that you have MySQL, XML and Zlib support built into your PHP.
help.joomla.org/content/view/34/132/
For Joomla 1.5 it’s recommended you have PHP 4.4.3 or above (for enhanced security).
A thread on the Joomla forums lists various hosting companies who are active Joomla community members. The list can be found at forum.joomla.org/index.php/topic,6856.0.html
Note that from now on, the steps are more or less the the same whether you are installing Joomla on a localhost or on a remote web server.
Getting the Joomla Files
This part is easy. Head on over to www.joomla.org and you will see a link to the download section on the home page, it looks like this:
The version number is the number given. This image shows that it's the 11th release in the 1.0 series.
Or you can head straight to the Forge and you will see all possible downloads:
forge.joomla.org/sf/frs/do/viewSummary/projects.joomla/frs
All versions are here as well as various upgrades from one release to another, important if you already have an installation of Joomla.
Important Note:
You cannot upgrade from Joomla 1.0 to Joomla 1.5. There are significant enough changes in the code that simply over writing files would break your site. The developer team has carefully chosen to talk about migration.
"Joomla 1.5 does not provide an upgrade path from earlier versions. Converting an older site to a Joomla 1.5 site requires creation of a new empty site using Joomla 1.5 and then populating the new site with the content from the old site. This migration of content is not a one-to-one process and involves conversions and modifications to the content dump."
dev.joomla.org/component/option,com_jd-wp/Itemid,33/p,107/
This has been a deliberate choice to minimize the number of users who might attempt the "overwrite the files" technique. More can be found in the forum:
"Joomla 1.5 is so significantly changed from 1.0 that there is no 'upgrade' path. This is the reason that we are providing a migration path. The concept is to build a new site and to migrate data from the old site. Extensions need to be installed and configured as if the site is new. The core data migration does reconstruct menu items for core elements and also keeps core module records with configuration settings."
David Gal - forum.joomla.org/index.php/topic,63232.0.html
Unzipping the files
You need to unzip, or unpack the big Joomla files you have onto your server. If you are running as a localhost, your server would be the WAMP directory mentioned above. If you are on a web host, you will need to upload the file and then unpack it. Perhaps the easiest way to do this is with cpanel. Almost all hosting companies provide it. Use your file manager to upload the zip file to public_html (or whatever you have on your host). You can then use file manager to extract the files.
Note:
I don’t recommend using Fantasico. Many hosts provide it but don’t always have the most current file releases.
Installing Joomla through a Web Browser
If you have got this far that means you have unzipped the Joomla package to either a remote web host or your local computer. Now for the fun stuff!
Using your browser of choice (Firefox of course), navigate to the location of all the localhost/Joomla. You will see the first installation screen.
Choose Language:
Here is the first look at some of the internationalization features of Joomla 1.5, you can select amongst many languages for the installation instructions.
Pre-Installation Check
A critical part in the installation process, this checks if all the minimum system requirements are met.
The first set are required minimums, if they are red (not met) then you need to find a new environment (change hosts), talk them into changing their environment (upgrading PHP for example). Note that the last item is a permissions issue on a file that is much easier to rectify. You can usually change permissions through the cpanel provided by your host. This tool is generally an industry standard.
The second set is recommended settings. If you don't meet them you can still install Joomla but it you experience problems with functionality and security.
Once you are green to go, click next.
License
Joomla is released under a GNU/GPL license. One of the most common questions regarding this license is “can I remove the footer link that says Powered by Joomla”. It’s actually perfectly OK to do this, you just have to keep the copyright statement in the source code. However, I would recommend that you keep the link.
Why?
Joomla is an open source project, it receives no funding from any kind of revenue from selling its software. The bottom line is that thousands of developers around the world are developing this software that you are using right now. If you had to buy it from a commercial company, it would cost tens of thousands of dollars, but you are getting it for free. In return, keep the link, it will help the project gain in popularity and grow. Don’t hide the fact that you are using Joomla, be proud of it! And don’t be concerned about any kind of SEO dilution with an extra link off your page. Links to authoritative sites actually help you SEO!
OK, I’ll get off my soapbox now…
Database Configuration
This is one of the main pages of the installation process, it’s where you need to enter important information about the database that your Joomla site will use. Note you will see a drop down for the database type. Joomla 1.5 only really runs on SQL, but some of the foundation has been laid for the next release, 2.0, to use more types, for example Oracle.
The hostname will almost always be “localhost”
The Username and password will have been provided by your hosting company, usually in an email you got when you created the account.
If you are installing on a localhost using WAMP or XAMPP, the Username is usually “root” and the password is nothing/blank.
Once you have entered this information, click Get Privileges and the Joomla installer checks to see if that user has rights to create a database. You should see this message:
If you made an error, or the user does not have sufficient permissions, then you get this message (after a small delay):
If the user you have does not have permissions then you can ask your hoster to pre-create a SQL database for you to use.
Available collations refer to various character sets available for different languages. When you click the button you get a list of what is available:
Pick a Database name for the SQL database that Joomla will use. Use some sort of name that is not confusing. Other scripts use SQL databases and before you know it you might have several on your server and will need to tell them apart. Don’t use spaces in the name.
If you are running several Joomla sites but only have access to one database, you will need to use a table prefix to distinguish them. You’ll need to enter the prefix in the advanced settings (below)
Note if your user did not have database creation privileges and you were provided with a database instead you would obviously put that in as the name.
The advanced settings are concerned with what content the site starts with and also the table prefixes mentioned above.
If you have an existing site and you are reinstalling over the top, you will need to select Drop Existing Tables. If you need to keep a back of them, select Backup Old Tables. Using “jos” as a table prefix is conventional unless you have multiple sites in the same database.
Main Configuration
The Main Configuration page determines how you will insert content into your site. You have three choices:
* Install Sample Data
This installs the default Joomla content that you have probably seen all over the web with “Welcome to Joomla”. Note that is also includes all the menus, navigation links and sections/categories. If you are learning how to use Joomla this is highly recommended. Its easier to adapt and revise than to start from scratch.
* Load SQL script
This is a SQL file that might have a customized set of content
* Migration from previous versions
This is a special function that is part of a process to migrate a Joomla site running on 1.0 to 1.5 and requires a special component to do so. This is discussed more in the Appendix.
Give your site a name (pay attention to SEO keywords) and then enter the super administration information. This will be the first user in the site and automatically gets that status. Note that if you don’t change the password, it will use the one shown on the left. Make sure you write it down!
Cross your eyes, close your fingers and click next. Hopefully you will see this screen
If you do get this result, you can investigate different language options, view the site or jump right to the administration of your site.
If you don’t get this page, then you have some work to do. Often issues arise because of server environments. If the solution is not obvious, a useful step is to copy the error message or the main part of it and then search for it both on the Joomla help forums, forum.joomla.org and in Google. The chances are if you get an error, someone else has before you.
Joomla is a complex series of PHP scripts that run on a web server. When you browse a Joomla site, these scripting are being generated on the fly and creating what you see on the pages of the site. The key words here are web server.
Running and Testing Joomla Without a Hosting Account
You cannot download Joomla and try to run it on your computer like an exe file. It has to have a web server, which means you need to have a hosting account. Sounds obvious, but I have had a couple of people if they needed windows XP to run Joomla!
Now, before we shell out our hard earned money for a hosting account, there is something else you can do first. You can actually run a web server on your local computer, in other words, your desktop or laptop. This is known as having a localhost. It may sound like I just contradicted myself from the previous paragraph, but not quite. You can’t "run" Joomla itself on your own computer, but you can install a localhost web server for it to "run on".
What you need to pull this off is some software that runs Apache, PHP and MySQL on your computer. These are the same software packages that power websites. There are two popular ones, WAMP (www.wampserver.com/en/index.php) and XAMPP (www.apachefriends.org/en/xampp.html) and they are both free (PGL license)
I am going to quickly run through setting up WAMP, not that this package is windows specific.
Download WAMP from the above link, and then install it. It will create a folder c:/wamp/www
Run WAMP, you should get a handy icon in your system tray:
You need the dial to be white to continue. Note if you run Skype, it interferes with WAMP and so you have to start WAMP without Skype running (and then start Skype if you need it)
Now open a browser and go to localhost (no "www")
You should see the following page:
If you are not seeing this then you should stop and figure out why. You have to get this page before you can proceed. The WAMP site has some helpful troubleshooting FAQ's and a forum.
You should see your folder called "Joomla" in the list of Your Projects. Click on that folder and you will get taken to that "website".
Installing a Joomla Site on a Hosting Account
So let's assume you either have a hosting account, or are going to get yourself one. There are some minimum requirements for Joomla to run, and they are slightly different for the different versions.
Here are the minimum requirements for Joomla 1.0
* PHP 4.2.x or above - www.php.net
* MySQL 3.23.x or above - www.mysql.com
* Apache 1.13.19 or above - www.apache.org
You must ensure that you have MySQL, XML and Zlib support built into your PHP.
help.joomla.org/content/view/34/132/
For Joomla 1.5 it’s recommended you have PHP 4.4.3 or above (for enhanced security).
A thread on the Joomla forums lists various hosting companies who are active Joomla community members. The list can be found at forum.joomla.org/index.php/topic,6856.0.html
Note that from now on, the steps are more or less the the same whether you are installing Joomla on a localhost or on a remote web server.
Getting the Joomla Files
This part is easy. Head on over to www.joomla.org and you will see a link to the download section on the home page, it looks like this:
The version number is the number given. This image shows that it's the 11th release in the 1.0 series.
Or you can head straight to the Forge and you will see all possible downloads:
forge.joomla.org/sf/frs/do/viewSummary/projects.joomla/frs
All versions are here as well as various upgrades from one release to another, important if you already have an installation of Joomla.
Important Note:
You cannot upgrade from Joomla 1.0 to Joomla 1.5. There are significant enough changes in the code that simply over writing files would break your site. The developer team has carefully chosen to talk about migration.
"Joomla 1.5 does not provide an upgrade path from earlier versions. Converting an older site to a Joomla 1.5 site requires creation of a new empty site using Joomla 1.5 and then populating the new site with the content from the old site. This migration of content is not a one-to-one process and involves conversions and modifications to the content dump."
dev.joomla.org/component/option,com_jd-wp/Itemid,33/p,107/
This has been a deliberate choice to minimize the number of users who might attempt the "overwrite the files" technique. More can be found in the forum:
"Joomla 1.5 is so significantly changed from 1.0 that there is no 'upgrade' path. This is the reason that we are providing a migration path. The concept is to build a new site and to migrate data from the old site. Extensions need to be installed and configured as if the site is new. The core data migration does reconstruct menu items for core elements and also keeps core module records with configuration settings."
David Gal - forum.joomla.org/index.php/topic,63232.0.html
Unzipping the files
You need to unzip, or unpack the big Joomla files you have onto your server. If you are running as a localhost, your server would be the WAMP directory mentioned above. If you are on a web host, you will need to upload the file and then unpack it. Perhaps the easiest way to do this is with cpanel. Almost all hosting companies provide it. Use your file manager to upload the zip file to public_html (or whatever you have on your host). You can then use file manager to extract the files.
Note:
I don’t recommend using Fantasico. Many hosts provide it but don’t always have the most current file releases.
Installing Joomla through a Web Browser
If you have got this far that means you have unzipped the Joomla package to either a remote web host or your local computer. Now for the fun stuff!
Using your browser of choice (Firefox of course), navigate to the location of all the localhost/Joomla. You will see the first installation screen.
Choose Language:
Here is the first look at some of the internationalization features of Joomla 1.5, you can select amongst many languages for the installation instructions.
Pre-Installation Check
A critical part in the installation process, this checks if all the minimum system requirements are met.
The first set are required minimums, if they are red (not met) then you need to find a new environment (change hosts), talk them into changing their environment (upgrading PHP for example). Note that the last item is a permissions issue on a file that is much easier to rectify. You can usually change permissions through the cpanel provided by your host. This tool is generally an industry standard.
The second set is recommended settings. If you don't meet them you can still install Joomla but it you experience problems with functionality and security.
Once you are green to go, click next.
License
Joomla is released under a GNU/GPL license. One of the most common questions regarding this license is “can I remove the footer link that says Powered by Joomla”. It’s actually perfectly OK to do this, you just have to keep the copyright statement in the source code. However, I would recommend that you keep the link.
Why?
Joomla is an open source project, it receives no funding from any kind of revenue from selling its software. The bottom line is that thousands of developers around the world are developing this software that you are using right now. If you had to buy it from a commercial company, it would cost tens of thousands of dollars, but you are getting it for free. In return, keep the link, it will help the project gain in popularity and grow. Don’t hide the fact that you are using Joomla, be proud of it! And don’t be concerned about any kind of SEO dilution with an extra link off your page. Links to authoritative sites actually help you SEO!
OK, I’ll get off my soapbox now…
Database Configuration
This is one of the main pages of the installation process, it’s where you need to enter important information about the database that your Joomla site will use. Note you will see a drop down for the database type. Joomla 1.5 only really runs on SQL, but some of the foundation has been laid for the next release, 2.0, to use more types, for example Oracle.
The hostname will almost always be “localhost”
The Username and password will have been provided by your hosting company, usually in an email you got when you created the account.
If you are installing on a localhost using WAMP or XAMPP, the Username is usually “root” and the password is nothing/blank.
Once you have entered this information, click Get Privileges and the Joomla installer checks to see if that user has rights to create a database. You should see this message:
If you made an error, or the user does not have sufficient permissions, then you get this message (after a small delay):
If the user you have does not have permissions then you can ask your hoster to pre-create a SQL database for you to use.
Available collations refer to various character sets available for different languages. When you click the button you get a list of what is available:
Pick a Database name for the SQL database that Joomla will use. Use some sort of name that is not confusing. Other scripts use SQL databases and before you know it you might have several on your server and will need to tell them apart. Don’t use spaces in the name.
If you are running several Joomla sites but only have access to one database, you will need to use a table prefix to distinguish them. You’ll need to enter the prefix in the advanced settings (below)
Note if your user did not have database creation privileges and you were provided with a database instead you would obviously put that in as the name.
The advanced settings are concerned with what content the site starts with and also the table prefixes mentioned above.
If you have an existing site and you are reinstalling over the top, you will need to select Drop Existing Tables. If you need to keep a back of them, select Backup Old Tables. Using “jos” as a table prefix is conventional unless you have multiple sites in the same database.
Main Configuration
The Main Configuration page determines how you will insert content into your site. You have three choices:
* Install Sample Data
This installs the default Joomla content that you have probably seen all over the web with “Welcome to Joomla”. Note that is also includes all the menus, navigation links and sections/categories. If you are learning how to use Joomla this is highly recommended. Its easier to adapt and revise than to start from scratch.
* Load SQL script
This is a SQL file that might have a customized set of content
* Migration from previous versions
This is a special function that is part of a process to migrate a Joomla site running on 1.0 to 1.5 and requires a special component to do so. This is discussed more in the Appendix.
Give your site a name (pay attention to SEO keywords) and then enter the super administration information. This will be the first user in the site and automatically gets that status. Note that if you don’t change the password, it will use the one shown on the left. Make sure you write it down!
Cross your eyes, close your fingers and click next. Hopefully you will see this screen
If you do get this result, you can investigate different language options, view the site or jump right to the administration of your site.
If you don’t get this page, then you have some work to do. Often issues arise because of server environments. If the solution is not obvious, a useful step is to copy the error message or the main part of it and then search for it both on the Joomla help forums, forum.joomla.org and in Google.

Some Examples (Copy and Paste this into a text/code editor)
A simple program is given by Bjarne Stroustrup (developer of C++) to check your compiler:
#include
#include
using namespace std;
int main ()
{
string s;
cout << "jhun \n" ;
cin >> s;
cout << "Hello, " << s << '\n' ;
return 0; // this return statement isn't necessary
}
// The sum of two numbers.
#include
using namespace std;
int main ()
{
int no1, no2, sum ;
cout << "\nEnter the first number = " ;
cin >> no1 ;
cout << "\nEnter the second number = " ;
cin >> no2 ;
sum = no1 + no2 ;
cout << "\nThe sum of "<< no1 <<" and "<< no2 <<" = "<< sum '\n' ;
return 0 ;
}
3.
3
Save this as sum.cpp, Don't confuse there are many other extensions for C++ files, choose any of them (like *.cc, *.cxx, *.c++, *.cp) .
HINT : It should say Save as Type: {select "All Files"}
4.
4
Compile it.
For users of linux and gcc compiler
Command : g++ sum.cpp
Users of Window can use any C++ compiler
Like MS Visual C++ or any they like to use
5.
5
Run the program
For users of Linux and gcc compiler
Command : ./a.out (a.out is a executable file produce by compiler after compilation of program.)
