Dedicated Server Hosting / Dedicate Sercer

2 comment(s) |

A dedicated server hosting(dedicated service or managed hosting service) is a type of Internet hosting in which the client leases an entire server not shared with anyone. This is more flexible and secure than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc.
From a single web server to a comprehensive multi-server solution, dedicated server hosting gives you the hardware and management services you need for a low fixed monthly fee. Dedicated Web hosting reduces up front costs while giving you the flexibility to expand and change as your business requires. Explore the components of your custom dedicated server solution, designed for your needs and budget.
Server administration can usually be provided by the hosting company as an add-on service. In some cases a dedicated server can offer less overhead and a larger return on investment. Dedicated servers are most often housed in data centers, similar to colocation facilities, providing redundant power sources and HVAC systems. In contrast to collocation, the server hardware is owned by the provider and in some cases they will provide support for your operating system or applications.

Dedicate Hosting Server management can include some or all of the following:

* Operating system updates
* Application updates

* Server monitoring
* SNMP hardware monitoring
* Application monitoring
* Technical support
* Firewall services
* Antivirus updates
* Security audits

* DDoS protection and mitigation
* Intrusion detection
* Backups and restoration
* Disaster recovery
* DNS hosting service
* Load balancing
* Database administration
* Performance tuning
* Software installation and configuration
* User management
* Programming consultation


Network and Security

Once your needs grow beyond a single server, your dedicated server hosting environment requires a network and security infrastructure. Multi-tier environments may include private-backend networks to segregate communications, firewalls to control access and load balancers to enable scalable and redundant applications.

Storage and Backup
Dedicate Server should have a broad range of server backup options to ensure your critical data is always protected.

Dedicated hosting server providers define their level of management based on the services they provide.

Get Best Picture Quality on LCD Monitor

0 comment(s) |




When we bought the new LCD, we just plugged it to our computer and tried to set some suitable resolutions. We were not at all happy to see the image quality as the pixels were not sharp and crisp. We even faced difficulty in reading the text on screen as it got bit blur.

Here is how we fixed it to get the best picture quality on our LCD Monitor.

1. Install the drivers that come along with your monitor:

Although LCD Monitors are considered to be plug-and-play, but in order to get the best picture quality, you should install the drivers which come along the monitor. You may also get some software tools to adjust all the monitor related settings in an easy way.

2. Correct Resolution :

Every LCD Display has a native resolution or optimum resolution, this is the resolution at which it will give the best picture quality. Set the resolution to native or optimum resolution. Check the optimum resolution in the menu or manual of the monitor. You may not find this resolution in the option of your graphics settings. In such case, you need to upgrade your graphics driver.
(In Windows XP, just right click on a clear part of the desktop and click Properties to bring up the Display window. Click the Settings tab at the top. Drag the slider in the "screen resolution" field right to set the resolution to the highest setting. Click OK and then the LCD monitor will start using that new resolution)
3. Enable clear-type in appearance settings :
Clear type will make the text look really smooth and easy to read. Follow the below steps to enable clear-type effect.

Right click on desktop --> click Properties --> Click on Appearance tab --> Click on Effect button

4. Adjust Contrast and brightness:
Set the contrast and brightness both to 50 percent. Now increase the contrast to a level (more than 50%) which makes you view the screen comfortably. Now decrease the brightness (to less than 50%) to a level which makes you see the picture best. Higher contrast and lower brightness gives a pleasant picture quality.

That’s simple, isn’t it.??
Tips:
  • Read the manual that came with the LCD monitor, it should have this information listed.
  • Go to you graphics card manufacturer's web site and download the latest drivers.

    Running Blog on a USB flash drive

    0 comment(s) |


    Do you know now you can use your USB Pen drive as “mini server”?

    There is an open source WAMP (Windows-Apache-MYSQL-PHP) bundle called XAMPP that are able to run most PHP based scripts directly from the bundle’s installation directory.You can use XAMPP to install many other scripts like Joomla, Drupal, Moodle…etc, and work on them in your leisure time, right from your very own “mini server”. Although XAMPP turns your little USB drive into a “mini server”, the only one who can access “localhost” is you.

    Just download it as a zip file, and unpack it onto your USB flash drive. In order to run a site or a blog,If you want to run www.no1-tutorial.co.cc in USB , you need to create a folder with a specific name in the htdocs folder of your XAMPP installation directory.

    So, if you named your folder as “no1-tutorial” and your flash drive is named as E:\, the path should look like this:

    E:\XAMPP\htdocs\no1-tutorial

    So briefly, the steps to run a your blog on a USB flash drive are just:

    1. Install XAMPP by unpacking it onto the drive.
    2. Click on the icon file named “xampp-control”.
    3. Start Apache and MySQL by clicking “start” for each of them.
    4. Open a browser window and type in http://localhost/xampp
    5.You’ll see a splash screen; click on phpMyAdmin and create a new database with your chosen name by entering it into the empty field and clicking on the “create” button.
    6. Copy your blog files into E:\XAMPP\htdocs\no1-tutorial
    7.Edit the wp-config-sample.php as you would for a self hosted your blog. You may use the username of “root”, and no password is needed (because the user “root” has by default, all privileges, and no password. )
    8.Go to the url http://localhost/no1-tutorial and the rest is history.
    See how easy it is....Just try

    The Device Generic volume cannot be stopped right now. Try stopping the device later
    This error comes when you have an application which is running from your pen drive or may be some file or document opened from your pen-drive when you are removing your drive.

    Assign a letter for a drive

    0 comment(s) |

    If you have a drive which Windows XP has no drive letter assignment stored it assigns the first available drive letter. The search goes upwards in the alphabet and starts at 'A' for floppy drives, at 'D' for CD-ROM drives and at 'C' for all other types.
    Windows XP can save exactly one assignment per drive letter. So when a drive is attached again it gets the same letter as before. But the drive letter is not reserved while a drive is not present and therefore reassigned to another drive if required. When this happens the former assignment is overwritten and the first drive gets the first available drive letter again even its former drive letter is available when it's being attached. The former assignment just doesn't exist anymore.
