Online Gaming Servers and their operations

Online gaming servers are a great way for every one to enjoy spectacular games. With the help of these gaming servers, you do not need a separate graphics card ad you successfully override the hardware requirements of any game. The game processing and graphic texturing is performed at the server and delivered via world wide web. A simple application or web page can be used to connect to the server.

The development of an online gaming server is yet another discussion which involves great hardware requirements and high bandwidths for communicating with all the connected players. Online gaming servers use server side web technologies to send and receve data between client and server.

Online gaming servers promote gaming communities where people can actually build weapons, trade them and make friends eve. There are some spectacularly popular games on the internet today with thousands of online gaming communities. These games are accessed by simple web applications or web sites and give a memoriable plasybak experience.

One of the world's top such games is World of Warcraft which has emerged as the biggest gaming servers available on the internet today. There are huge communitoes. Weapons, Gold, Accesories and other gears are collected here and can be sold in online communities. People do sell their belongings for a price and people buy them as well. With millions of online gamers, Wrld of Laracraft, stands as the number web accessed game.

Most of the modren day games present online experience as well. These games require heavy graphics and use multiplayer features to connect different players. The gaming servers here have less complicated tasks including only the data transmission and processing tasks. All the game computing is donr at the client side and these games are quite popular too.

Why updating your hardware drivers is important?

Why updating your hardware drivers is important?

We all have many a times encountered issues with our devices. Some times you go out to run a game or an application and your display or audio goes out. This phenomenon is also observed when you update your operating system or install a service pack and your old drivers go obsolete.

The real reasons behind the hardware drivers getting old is the simple fact that with the passage of time, new services are introduced rendering the old drivers obsolete and unusable. First of all let us take a look at what a driver is. A driver is a set of information about all the services oif a hardware device and how can the operating system access those services.

When you change your operating system, you simply change all the access handles of your software operations. In this case, there needs to be a new information for handling those devices. A new driver would be required in the cases that the operating system no longer knows how to operate the new hardware anymore. You can update your driver easily by downloading the latest version from the vendor's website.

Many software and especially games require latest drivers. These drivers actually streamline the processes and functionality obtained from a hardware device. You wont believe but in many cases, you really d not need to upgrade your hardware. You can, instead, just look for the latest and the most appropriate drivers for your device and in 70 % of such cases, your problem will be fixed.

The best sources to look for new drivers would be at the hardware vendor's website. You can simply contact them for driver compatibility issues and they might be able to propose solutions.

If you are using Wndows Vista then it automatically generates and report and provides you with solutions about upgrading and compatibility issues with the drivers. It is always advisable to keep your drivers updated at all times in order to get a smooth performance from your PC.

Use netsh command in batch file

Use netsh command in batch file

It is simple to use netsh command in a batch file. These files come with the extension .bat and can be used wherever you like. You can run all the commands with one click.

Open a note pad and type the desired netsh command. For example we want to execute the following commands in order
Then type
• netsh interface set ip address "Local Area Connection"
• netsh interface set ip address "Local Area Connection" dhcp.
• ipconfig

After typing this click save. In the save file dialogue box, you have to take care of one thing. Change file type to *.* and then type a file name.bat. Let us assume dhcp.bat. Save the file with this name and then close the notepad. Double click the file name and nothing will happen. Remember the Vista Hell. Right click on the file and cluck Run as Administrator. Success. Congrats.

You can make another .bat file let’s say static.bat a nd type the following commands
• interface set ip address "Local Area Connection 2" static 192.168.0.10 255.255.255.0 192.168.0.1
• ipconfig

You can run it in the same way and you will have used a batch file for execution of your commands.

Change IP Address from Command Prompt

How to change IP from command prompt

A few days ago I was wondering about how to change IP address from a command prompt. I use windows vista and it has essentially made every process lengthier than it used to be. I often winder how things wrk and especially IP related tasks that used to be so simple like right clicking on the network icon and changed the properties. and in Vista, the process has gone even more complicated.

If you have been thinking about how to change IP address from a command line prompt then this article is for you

The process of changing an IP address is pretty simple with commad prompt. It simplifies the process and you can even use it with a batcjh file. First let us take a look at the command line to change IP address

IP address configuration command s calld "netsh".

The syntax of the command is

netsh interface set ip address "Local Area Connection" static/dhcp ip address subnet mask gateway

Let us assume now that you want to release the ip address then use the following command line from the command prompt.

netsh interface set ip address "Local Area Connection"

When you use this command you will get an error message saying " Elevation required.

In windows vista this is an important issue with everything. Dear Friends welcome to the Administrator everything hell.

Ok lets start again

click the start icon. Type cmd and see the cmd.exe come on the top. Right click on the cmd.exe icon above and click run as administrator.
Type the command in it and voila. your IP settings will be emptied.


To check type ipconfig in the same command prompt and get your ip address fields empty.

Anopther point to be noted here is that your DNS entries are not deleted or changed this way so dont worry.

Ok let us suppose now you want to change you Local Area Connection 2's properties we want to change the ip address to 192.168.0.10/24 or simply subnet mask 255.255.255.0 and gateway

So the command would be
interface set ip address "Local Area Connection 2" static 192.168.0.10 255.255.255.0 192.168.0.1

We have successfuly changed the properties of Local Area Connction 2. Check it with ipconfig command.

Note: Do not forget that netsh command wont function properly without administrator rights.

Now we have set static address
Lets see if we have DHCP and we want to automatically assign new address

There are two ways to accomplish this task from command prompt.

First
Run the cmd.exe with adminitrator privilages then type these commands in order

1. ipconfig /release
2. ipconfig /renew
To check the new IP type ipconfig /all

Second
Run the cmd.exe with adminitrator privilages then type these commands

1. netsh interface set ip address "Local Area Connection"
2. netsh interface set ip address "Local Area Connection" dhcp
3. ipconfig

Now you can successfully change your IP address from the command prompt. In the next article I will explain how to use this in batch file

The difference between different graphic card ports and slots

The difference between different graphic card slots

Graphic cards are very popular among gamers around the world. When you go out in the market to buy a new or used graphics accelerator card for your gaming or business processing requirements. In reality, there are three types of graphics card ports available in the market as of today. These ports can be named as PCI, AGP and PCI Express ports.

PCI Ports
PCI ports are among the most primitive form of graphics ports available. These are white colored ports and a graphics card can be affixed on its slot. The interface usually supports variable bit rate and has a latency of 16 or 32 depending upon the type of mother board, make and model. PCI ports are almost obsolete in the market because they fail to comply with the speed requirements of latest cards.

AGP Ports
AGP ports are among the most common types of graphics acceleration ports available in the market. Aas compared to PCI ports, AGP ports are 4 - 8 times faster in performance and processing which means the data can travel at a much faster pace. AGP ports are smaller in size as compared to PCI ports. AGP ports are brown in color. AGP ports are suitable for gaming and business processing but the more modren computers have replaced these ports with PCI Express ports.

PCI Express Ports
PCI Express ports are the most modren type of graphics accelerator ports. All of the modren graphics ccelerator cards come with PCI Express interface. PCI Express ports are white in color but are much smaller. Two types of PCI Express ports are available, PCI Express 1.0 and PCI Express 2.0. These ports have 16 to 32 times faster speeds than PCI slots.

How to setup a graphics card?

Going out of graphics card shopping? It is a tedious and painstaking job at the end of the day. With so many options and types available, it is pretty hard to think what is best for you under which requirements. Most of the graphic card manufacturer companies usually use a chip from Nvidia or ATI. These two companies are the primary manufacturers of graphics card chips known as GPUs. These GPUs allow for graphics processing releasing the burden off the processor and streamlining the processes.

Graphics cards usually are connected to AGP, PCI or PCIe ( a.k.a. PCI Express). Among the all three, PCI Express graphic cards are of the best performance with newer boards supporting PCIe 2.0 ports. These ports have 16 times the speed of regular PCI slots. You can connect a card to a port and watch the results and difference. A graphics card is usually a large rectangular card with a processor and cooling fan mounted on top of it.

Usually boards have built in graphic chips but they are not good enough for modern day gaming and graphics needs. When you connect a graphics card to your PCIe slot; you do not need to change anything. Usually an analogue monitor is connected through a DVI output a.k.a. Digital Video Integrated output. Previously you had to change your bios settings and output options. Modern graphics cards can perform all this by themselves by changing the bios settings. Once you install the card, you are good to go.

Once you have mounted the card and powered up the system, your operating system will load and then you will have to install the drivers through a compact disk. After you install the drivers, you are ready to run it all. Enjoy your games and have fun.

How to run Windows Vista at Optimum speed in 80$

The first commercial version of Windows Vista was first introduced in 2005. Windows Vista came with a sleek design, an ever growing need for high resources and cool graphics. The main feature that differentiated vista from other operating systems was its great look and design. There are some pretty cool things in vista that makes it stand ahead of the race but wait thats not all.

Along with so many good looks come the disadvantages. For example, you can not possibly expect vista to run smoothly without having a high performance graphics card. Windows Vista has something called arrow interface and this interface alone is too heavy to be handled by ordinary graphics cards along with maintaining the performance.

If you have a PC lets say an Intel P4 like 2. GHrtz and blow with 512 MB RAM and no graphics acceleration, you might not be able to enjoy Windows vista wth its full features. It might come to you as a surprise because Windows XP would have been running like anything on this PC but since this is the new Hell from Microsoft thats why it does need more resources.

Windows Vista can not run at optimum speeds without a separate GPU ( Graphics processing unit) handling all the graphics and the rest is left to your normal CPU. It is also a notable thing Here to increase ram.

Let us take a look at the hardware requirements to run Windows Vista at optimum levels.

1. We need to have a GPU also known as Graphics Processing Unit or Graphics Accelerator. These GPUs have their own operating speeds,a seperate procssor and internal memory. The memory is called Graphics memory and often comes in GDDR1, GDDR2, GDDR3, GDDR4 or GDDR5.

You can go for a GPU of series 8 Nvidia or 3700 series from ATI. 256 MB DDR cards are good enough to run Windows Vista at optimum speeds. You can get it for as cheep as 50$. Oh yes.

Second thing would be to consider a RAM. You can go for a DDR2 RAM with speeds upto600 - 800 Mhrtz. You need 1 GB - 2 GB memory and they are quite cheap as well. You can go for DDR1 1 Rams as well but your business application performance may suffer. You can get a 1 GB chip provided you have already a 512 MB or 1 GB module in your system. This would cost you around 30 $.

Now you are all ready to run windows vista at optimum speeds. You did not have to change your motherboard or processor or anything. You are all good to go in less than 80$. Learn more about Windows Vista here.
