Tips to buy a desktop computer

Are you planning to buy a computer? Wondering whether you should go for a branded one or for an assembled one? Whatever you choose, make sure the components of the computer are good and branded. You must also consider your requirements as well. Why do you need the computer? Is it only for surfing internet and perform simple task? Or you want to buy one for performing multimedia task or run programming language. Remember, depending upon your requirements, the configuration of the computer needs to be decided. 

Some technical information that you must know for buying a desktop computer is given below. For more assistance on PC buying, you can talk to a computer services company.

•     Processor – If you are buying computer for some simple tasks, you can go for an AMD or Intel processor which are available at an affordable price, while for running programming or multimedia programs, you should choose a high-end one, like the 64-bit Intel iCore or Athlon CPU.

•     Motherboard – Another most important key component of a computer system is motherboard. This is part where the CPU and RAM will be placed. So, it is always suggested to opt for a good motherboard. You also need to ensure about enough amount of memory, PCI slots so that you can upgrade the system in future.

•     Ram – Since RAM is a very important component of a computer, you must opt for a good one with high speed. Remember, faster hertz of the memory ensures better performance. Minimum 1 GB of RAM should be installed.

•    HDD - The hard drive is the place where you will install OS and other software and save important data as well. Choose a renowned brand like Barracuda, Sandisk, Samsung, etc. with minimum 100 GB memory.

•     Monitor – You can opt for a TFT monitor which are available in the market in affordable price. These are of various brands and of various sizes as well. Choose any one of them according to your budget and requirements.

There are many other components such as a DVD writer, sound system, UPS, SMPS, etc. that are also important part of a desktop computer.

Learn Networking through Tech Support

Networking your office and home computer allows you to share information and files which might be important for you. Through networking you can connect thousands of machines together. For a small network, the Windows workgroup allows you to share information in your home and office. A mapped network drive is created to move information from machine to another. This allows you to read, edit and save information which is similar to working files on your local and physical hard drive.

 For this right-click on “My Network Places” on your desktop. If you have Windows Vista or 7 then the icon will be labeled as “Network”. Now select “Map Network Drive” from the menu. Now enter the location of the remote computer drive. It will be something like this \\computer_name\c$ into the text box if you want to access information from the “C” drive of your computer. Now replace “ computer_name” with the name of your computer. Just remember that, the “C” drive has dollar sign suffix. Now click on

 “Finish”. The network drive is mapped to your machine. Now double-click on “My Computer” from your PC’s desktop to verify if it is complete and start downloading the files from your remote machines.  If you have Vista or Windows 7 the icon will be labeled “Computer”.

Now double-click on the new mapped drive. The mapped drive has a letter next to it and it displays the location of the folder in the remote machine’s folder. You can download files from the mapped drive to the local “C” drive. You can double click on files to read and edit them from the remote machine.

Firewall in Windows

A firewall is a program or a service that is designed to protect the resources of a user from external attacks, threats, etc… Likewise in Windows too we find a similar type of firewall known as Windows Firewall. But the name Windows Firewall was applicable with the release of Windows XP service pack 2 in 2004. Prior to this it was known as Internet Connection Firewall. In simple words, Windows Firewall is a protective boundary that monitors and restricts information that travels between your computer and a network or the Internet. This provides a line of defense against someone who might try to access your computer from outside the Windows Firewall without your permission. This program or service came into existence with the introduction of Windows XP; older windows operating system prior to Windows XP didn’t had this firewall feature inbuilt into the operating system. In order to access and configure Windows Firewall, you need to:

• Click on Start
• Click Control Panel
• From control panel click Security Center
• In windows security center under manage security settings for, click on Windows Firewall
• Once the window firewall pop up opens up, you can configure it according to your needs, like you can turn firewall on, you can turn firewall on without any exception (by giving a checkmark in the don’t allow exception checkbox) or you can turn firewall off.
• Once you are done configuring the firewall, click OK to exit and save the changes that you have made.

Web Ads with Zip Coded Targets

Advertising has always been target oriented where the right product has to reach the right customer. The challenge is about reaching the right person. In an attempt to reach the right person, the advertising industry has embraced the telecom industry and we are in a new age of zip code specific advertising. Web based advertising is an old concept now and the internet service providers are acquiring such routers with a special software which will be able to track the IP addresses to the level of zip codes and provide the information back to the advertisers for demography based advertising reasons.

Juniper Networks has tied up with Feeva, a software company which deals with computer networks and digital advertising to include a specific software in the router like the MX960 which will be able to track down the zip codes of potential customers which can be later used by the advertisers. How exactly does it accomplish it? Feeva attaches a tag in the HTTP header, consisting of a “zip+4” number which is more accurate than the normal five digit zip code.

Advertisers have been gathering data about demographic data, zip-codes but it is not reliable enough. IP address detection is only accurate within the twenty-five miles range and cookies that track the user’s surfing habits do not give information about the location of the marketer. This is where the importance of the technology lies.

However, there have been concerns with the privacy of the end user that is the potential customers but according to Feeva, no other personal information is divulged except the zip code. However, it is for the technicians to see into the security issues of the end system user. So what can we do to ensure our privacy?

 1)      A combination of firewall and antivirus/antimalware software configured properly in the system with special care for ICMP related packets over the internet.

2)      A home-network behind a router is very safe provided the router is configured properly with reference to security.

3)      Proper maintenance of the computer like deletion of cookies and junk software which gets accumulated as you visit the internet.

GRAPHICS CARD, WINDOWS7 AND 2D PERFORMANCE

Graphics card manufacturer ATI has come up with the driver version 10.4(Catalyst 10.4) for it ATI Radeon 5870 which is in close competition with NVIDIA GeForce GTX 480 and a lot is being talked about the 2D or the two dimensional performance that the two deliver but we are more interested with the 3D performance because we want a better performance in our games. However, 2D rendering is not less important when we complain about the slow performance in opening windows, folders and working with Word in Vista and Windows 7 being faster if we compare. Apart from the internal memory management of Windows 7, the graphics card installed in your computer will make a difference to the system performance in addition to the RAM present in it. In programming language jargon the Graphics Device Interface for the Application Programming Interface takes care of the “display” speed of the windows 7 and the redrawing of lines, polygons color-depth and pixels are involved in the 2D display speed.

The ATI has gained some good responses with reference to benchmark testing for 2D performance but still NVIDIA which is another giant is doing well with its GTX 480 product. These can handle high refresh rate for the screen as well which is again another factor to good 2D acceleration. Windows 7 has added a separate hardware 2D acceleration rate but with a question mark from the experts. Windows XP still competes in terms of 2D rendering speeds.

 

So we can conclude by saying that if most of your computer usage is related to office work which is related to 2D performance of the computer then go for a graphics card which offers you good 2D performance. The cards that I mentioned at the beginning of the article offer you good 3D performance as well if you are still concerned with the 3D performance factors. Windows 7(using direct X 11) should be the choice for over all system performance and for 2D performance as well since we are focusing more on the 2D performance issues. Windows XP is still good in 2D performance.

CLOUD COMPUTING – THE NEW BUZZ WORD

In modern day computing, the term “cloud computing” is a much used term. But what exactly is cloud computing all about? It is about using the recourses already present in the World Wide Web for better resource utilization, lesser cost in capital expenditure and increased scalability of hardware and software.

In cloud computing, the customers, better known as tenants, use third party resources to cut capital expenditure on hardware such as data storage as an example and pay rent for the resources used by them. Billing occurs on input/output resources, load balancing, IP addresses, GET requests and Put requests related to database management queries etc. It is not that, only the large companies take advantage of it. Individual users can take advantage of it as well. A person using online data storage is a good example of cloud computing. Using Google is another example of cloud computing.

Data storage, HTTP services, Web based services related to ASP, network based access to commercially available software, centrally managed multi-tenant architecture support – all come under the purview of cloud computing.

Well, we have already talked a lot about ‘Cloud Computing’. But we still did not discuss what a “cloud” is? Cloud is nothing but a diagrammatic representation of the World Wide Web to indicate the internet world outside the user’s computer system. A cloud could be of the type “public”, “private” and “community” depending upon the accessibility and security features.

Where security, device and location independence, scalability and cost could be the advantages of cloud computing, on the other hand there are some privacy issues associated with Cloud Computing as well. It has been found that due to security reasons of the country some espionage activities have occurred in the domain of “secured” cloud computing. While discussing about security, we must mention the presence of a few online antivirus scanners like Panda Cloud Antivirus. The concept is that, it takes lesser time to update a central server related to virus signatures instead of testing virus updates in separate laboratories. The concept is good enough as far as a quick response-time to a new virus is concerned but it is yet to be termed as the best.

A Website Can Keep Your Credit Card Information Confidential

Well, let’s start with an interesting piece of information – websites can keep your credit card information secret. Surprised? Although it’s very hard to believe, the statement carries some bare truth. For all the credit card it is important to have SSL (secured socket layer) to get the card information. Nowadays, we do receive a lot of promotional calls from different companies asking us to buy their products. And they ask for the credit card number. But the question is, how safe it is to provide our credit card numbers to others? This article will tell you how you can judge that the website is a safe one to share credit card number.

Following methods will help you out in this matter:

1)You will get notification from your browser that the SSL certificate is valid or not.

2)To check whether the site has a valid certificate or not, right click anywhere on the checkout page and then click on View Page Info in Firefox or Properties in Internet Explorer. Now find the button view certificate or certificate. The certificate will display the name of the certificate owner, which should correspond to the name of the business displayed in the address bar.

3)After you verify the SSL encryption, you can be assured that you have the right connection. Now it could be possible that the owner is not the actual seller of the product or the retailer may not have purchased the SSL certificates.

4)Check for a lock icon in the bottom right-hand corner of your browser window, or in the address bar. A locked transaction means the browser verified that the site uses at least minimum data-encryption protocols.

5)If you doubt the third party creditability, make sure that you are dealing with the correct vendor. Always look out for the vendors that take part in the Security Standards Council of the Payment Card Industry.

6)Keep the browser updated and the operating system as well to be assured that you have fraud controls available to you.

7)If you find any discrepancy on your credit card details then check the card details with your bank. Do check your credit card details on a regular basis.

8)Avoid using other tabs when your are providing card information.
