Many times you see that your computer is responding very slow though you have latest hardware with high configuration. There are chances for getting your computer being affected by virus, torjans, adware or any spyware which got into your system through infected cd’s pen drives, external hardrives etc…your machine can also be infected by some malicious programs such as spyware, adwares which usually crawl to your machine through freeware softwares, application or through game softwares which are freely available on internet. All these malicious program get their place in registry and start creating trouble for your machine,  thud you need to scan your system as often as possible using some reliable antivirus and antispyware tools. Make sure you update them as frequent as possible. Also you need to take care of your registry, as you install anyapplication on your system lot of information gets added to your registry for that specific application. Many times after using some application you uninstall them but its not necessary that such uninstallation will clear related data from registry thus your registry may get filledup with unnecessary data which may affect overall system performance. So its always better to clean your registry with atmost care. Overloaded registry not only causes registry problems, but can also slows down registry access resulting in poor performance of your machine. Thus to get good results you should try to scan and clean your registry on regular basis. You should also take backup of your registry which can be used in case of registry failure.

Harddrive is the most important part of your machine, all data is stored in digital format on this part of your machine. Thus you should take much care of your harddrive and should scan it regularly for virus, as if your harddrive gets affected all your data may also get corrupted and will be lost. You should remove unwanted files from your harddrive as they just eatup your precious space and may affect its performance. If you frequently install and uninstall new applications/programs on your PC, then your hard disk will also get filled up with orphan information left behind when you remove these programs so you need to install only applications which are must for you. Its always suggested to keep your machine free from unwanted rarely used applications.

Following measure should be taken for getting optimal performance of your machine.
*) Always use a registry cleaner tool to remove any orphan entries which may be left behind after you uinstalled any program or application
*) Take care to cleanup your harddrive using some good reliable Disk Cleanup tool which will clean up unwanted data, such as Temporary Internet Files, old program setup files etc…
*) Its always said “ Prevention is better then cure “ this matches perfect for your computer too.
So for better performance and faster system you must take all preventative maintenance steps for keeping your machine free from error and virus.

A firewall is a secure and trusted hardware/software application which is used to block unwanted logical ports and manage unwanted traffic. In simple words firewall is a barrier to  keep destructive forces away from your server which may be loading your server. A firewall is useful if you don’t want eternal users to access a particular host or service.
it useful to filter packets based on source’s IP address.
Its used securing your data and server from being get hacked.
Its most common use is to prevent denial of service attack, you can prevent certain level of DDOS attacks for your server..

You can consider firewall as a program or a device which can monitor, control all data transfer between any internal network with whole internet, A firewall ensures that all data communication in both directions is accordingly to security rules set.
Firewall technologies are configurable thus you can limit communication by direction, IP address, protocol, ports, or numerous other combination. There can be communication failure if data communication is not as per the rule set for all outgoing and incoming requests.  If you have access to the firewall of you server , you can configure it to enable the ports, protocols, and addresses that may optimize data communication.
As for security reasons you can configure your firewall to allow only TCP traffic which may cause the user to see frequent buffering of clips. User experience of the presentation is compromised; greater latency and startup times affect the time needed to view the clip, and delivery of the clip requires more total bandwidth.

General types of Firewall :

Desktop Firewall :

Allmost all operating system have built-in firewall applications which is responsible for protecting standalone machine, This type of firewall is designed to protect a single desktop computer and is of a great protection mechanism if the network firewall is compromised.

Software Firewall :

As the name suggest it’s a software application which can be installed on a server which is capable of preventing unwanted data communication. Many webmaster don’t prefer software firewall as most secure. This type of firewall is often used as an application firewall which means that the firewall is optimized to protect applications such as web application and email servers. All Software firewalls have built-in complex filters to inspect the content of the network traffic. This type of firewall is usually (but not always) behind hardware firewalls.

Hardware Firewall :

A hardware firewall is a dedicated hardware device which is installed on your system/server. These firewalls consist of network routers with additional firewall capabilities. Usually hardware firewalls are designed to handle heavy network traffic sites. Hardware firewalls are often placed on the perimeter of the network to filter the internet noise and only allow pre-determined traffic into the network.

Many-a-times hardware firewalls are used in conjunction with software firewalls thus hardware firewall filters out the traffic and the software firewall inspects the network traffic thus you get pure traffic and unwanted traffic can be blocked easily. If in case hardware firewalls are bombarded with bogus network traffic her comes the role of hardware firewall they drop this unwanted traffic and will only let in the right traffic for your network/server thus hardware firewall not only protects the software firewall but also allows the software firewall only to inspect proper network traffic thus such hardware and software firewall combination will surely optimizes the network throughput.

RAID i.e. Redundant Array of Independent Disks, is a mechanism which enhances the speed, storage capacity & reliability of your webserver using more than one hard disk instead of the traditional single hard disk solutions. In essence, RAID actually works in such a way which allows the multiple hard drives present on the machine to be combined and used as one big hard drive with different levels of benefits and also covers your risk of data loss. The higher your RAID level, the better risk coverage you get. Completely subjective to your need for data safety and redundancy, you can use several variations of RAID depending on your budget. RAID solutions are available starting from as low as $40.00 to a few thousand $$. There is no such thing called as the best RAID combination or implementation. What RAID levels you need is completely dependent on the applications, processes and softwares which run off the server.

Previously, RAID could be implemented and coupled with only the high end and most expensive server configurations. Now-a-days. with the advancement in technology and the vast amount of research which has been done on RAID, affordable yet effective RAID controllers have been made which can be easily procured and used. There are different RAID levels which exist.

Software Raid 0
This is not something we should be recommending but you will be asked about it. With Raid 0 you take two hard drives and turn them into 1 big HDD. This improves the storage space and performance but there is NO fault tolerance. If one of these drives were to fail, all data would be lost. There would be no option for recovery. If a client asks you about this, make it very clear that you do NOT recommend it.

Hardware Raid 1
This is an option for 2 hard drives and is highly recommended. Raid 1 offers a slight performance increase and also allows for any 1 of the drives to fail without the server crashing or data being lost. The main benefit of raid 1 is the cost. It’s relatively cheap to implement and can be offered to clients with a low budget. If a client was to have 2×250 GB hard drives in Raid 1, Only 250 GB would be available.

Hardware Raid 5
Raid 5 is slightly different from Raid 1 and Raid 10. Whereas Raid 1 and Raid 10 offer a slight performance increase, Raid 5 offers a much greater performance increase. Raid 5 contains a minimum of 3 hard drives. At any one time, any one drive can fail and the server will keep on working. If more than 1 drive fails, all data is lost. You may get people looking for game servers asking about Raid 5. If a client was to have 3×250 GB HDD in Raid 5, 500 GB would be available.

Hardware Raid 10
A Raid 10 array contains a minimum of 4 hard drives. In this configuration the drives are paired up and the data is mirrored. In theory, the server could sustain two hard drive failures and the server will keep on running. However, the server can not sustain two hard drive losses on the same mirrored pair. As an example, let’s say a server has HD0, HD1, HD2, and HD3. Four separate drives. In this example we will say that HD0 and HD1 are mirrored and HD2 and HD3 are mirrored. If HD0 and HD2 were to fail, the server would carry on running without data loss. If HD0 and HD1 fail, all data stored on HD0 and HD1 would be lost. Modern raid controllers are very efficient. At the first sign of any fault, on any drive, it will automatically declare it as faulty and will request the drive be replaced. Raid 10 doesn’t offer the same performance level as Raid 5, but is more reliable. This is highly recommended for clients with a high uptime requirement. If a client was to have 4×250 GB hard drives, 500 GB would be available.

Setup times for RAID depends on the level which one chose. Normally it takes between 24 to 48 hours, wherein the higher you go on the levels, the more time it takes for the setup to be done.
