Zaheer Ahmed Khan — Tue, 22 Jun 2010 15:03:32 +0000

Computer Systems are predominantly designed to perform hardcore computations especially for individuals who do jobs in industrial fields such as engineering and software development. On the other hand, in more modern times the more conventional users have been using computer systems as a complete entertainment center. Software programmers have created the best and latest entertainment capable applications available to average users for all different types of media such as gaming, music, videos and pictures.

Most PC systems are bought preinstalled with a DVD equipment and software application to play movies but sometimes system have to be reinstalled and you may be unable to install the applications that initially came from the manufacturer. In these situations, you will have to acquire a free easy to store and authorized DVD player application and sometimes you will also have to change your present DVD player for a newer one.

There are countless freeware DVD Player applications which are created and made accessible to anyone who can access the internet that are also free of costs. To begin you internet search you can find DVD Players by going through search engine sites such as Google.com. Since Google operates as a directory listing for details on almost anything, computer related and otherwise. This search will present you with a list of websites which in turn will display a listing of free burning applications. These applications can also be found on websites such as download.cnet.com and brothersoft.com/downloads, just to name a few. A majority of the websites that have free DVD player software have a group you can search through for softwares of that kind.

When you look for free DVD Player softwares ensure that you read all the details in regards to the software’s platform support. Most times these details are provided from the web page along with the guidelines for downloading and installing the software application. Most DVD Player softwares can be installed on both Windows PC and Mac compatible computers, but there are applications that ask that you store separate versions depending on the operating system that is in use.

Some of the popular DVD software players to choose form are VLC, Easy DVD Player, Gom Player, Zoom Player, Windows Media Player and more. VLC, Gom, Zoom, Easy DVD Player 2.0 and Windows Media Player are all convenient multimedia players and frameworks that are able to interpret almost all video formats as well as DVD disc. In most instances Windows Media Player, comes preinstalled on most Windows PC and it is very easy to use, primarily for novices to computer softwares.

At times these applications may require additional updates in order to play DVDs and other movie formats. For Windows Media Player this can be found by visiting the help menu and select a link for the latest updates that can control all or most of the video files including DVD’s. Sometimes you may have to download and install free codecs separately in order to interpret DVD data. There are normally a number of versions for this that are free and are supposedly functional on some PC’s system and not functional on other. All these applications can also be found on the Google search engine as well.

How to Download Free Antivirus

Bilal Akram — Tue, 15 Jun 2010 13:03:19 +0000

An antivirus software is a type of program that searches your hard drive and floppy disks for any known or potential infections. The market for this kind of program has grown because of Internet growth and the growing use of the Internet by businesses associated with protecting their computer assets.

Antivirus software provides an important layer of protection from a multitude of infections, trojan, worm, spyware, adware, dialer, keylogger and rootkit infections. Originally antivirus programs just detected infections and bug removers just picked up spyware but nowadays the boundary between antivirus and spyware removers is unclear. Most present antiviruses have at least reasonably good pick up rates of all forms of malware.

Malware includes viruses, trojans, worms, spyware, adware, dialers, keyloggers and rootkit threats that perform malicious tasks on a computer. With the huge increase in bugs, antivirus programs cannot keep up with detecting all of it. But employing more than one real-time antivirus uses much more system resources, can cause conflicts and even reduce protection. So I recommend you only choose one antivirus for real-time protection. Instead, you can grow your protection using other security software.

Looking at several free antivirus software can assist in locating programs which are vital in protecting your computer from infections threats and other forms of malware. After doing a couple of searches you will find that Avira AntiVir is one of the best antivirus programs out there now.

Firstly, AntiVir does not include web or e-mail scanning capabilities; this is only available in the paid version. The shortage of an e-mail scanner is not really a disadvantage, it just means that AntiVir won’t warn you of virus filled emails before you open them. But you should not open an infected email, AntiVir will continue to spring into action, so it doesn’t mean that you’re not protected from email-based infections. Secondly, AntiVir has advertisements that come up with every update, you can disable or take these ads.

Finally, AntiVir has a time-limited license. It is renewable, but be aware that you’ll have to from time to time go through the hoops. Although AntiVir had signature updating complications in the past this seems to be corrected now.

How to Set Up Ethernet Splitter

Zaheer Ahmed Khan — Sat, 22 May 2010 12:59:28 +0000

If you have more than one computers at home or at work, more likely you will need to distribute the internet connection among all the PC’s so that all the occupants can use the internet at once. For this reason you can employ an ethernet splitter to construct a set of connections where all the computers can be connected to take advantage of the web connection. So the network is basically all the PC’s connected by a communications device that facilitates sharing information among all the users.

If it is not convenient enough for you to buy an Ethernet splitter, then you can read this article to learn how you can create one on your own. But it takes time, patience and a little knowledge of wiring. By setting up an Ethernet splitter, you can link two or more PC’s at the same time through one Ethernet device.

In order to make your own Ethernet splitters you will require some devices and tools including two RJ45 Crimpable Plug, four RJ-45 keystone jack, a short Ethernet Cable Scrap around 2 feet in size and tools such as a RJ45 Crimp Tool Craft knife, 110 Punch Down Mechanism, Loctite Â Super Glue. First you will need to crimp the RJ45 Plug to the Ethernet wire. For this to be done you will require to follow a configuration codes taken from a hardware book or from the instructions on the package.
Now use the 110 Punch Down Mechanism to punch down the other end to the RJ-45 keystone jacks and take the other side of the cable and slice it to 9 inches and press down the four pairs with this wiring scheme, Jack #1: 1 White/Orange to pin 1keystone jack 2 Orange to pin 2 keystone jack 3 White/Green to pin 3 keystone jack 6 Green to pin 6 keystone jack #2: 4 Blue to pin 2 keystone jack 5 White/Blue to pin 1 keystone jack 7 White/Brown to pin.

Use the preceding information to create one more splitter so you eventually create two splitters. Plug one splitter to the RJ45 wall plate and join the two PC’s to the splitter. Now plug the other splitter to the patch plate and put two patch cables from the splitter to two free Ethernet jacks from the switch. If your splitter cables are right then the two leds from the knob on which the patch cable are connected should turn on. After this setup is complete, then you will be able to install two computer systems simultaneously connected using only one Ethernet cable. This method is similar to Power over Ethernet but instead of injecting DC, it is insering a next data. It is better if you can to pull one more Ethernet cord from the patch panel to the wall plate. Once you use these instructions then you should create a proper Ethernet splitter, if not you will need to start over the process all over again.

Laptops Vs Notebook Computers

However, both the Notebooks and Laptops appears to be similar as they both are portable and you can take them anywhere you want, but there are few differences between both of them.

Notebook Computers

Notebook computers are developed and designed to allow you to do computer work while on the move and still offer all the power a mobile users require for entertainment as well as work.

A standard Notebook computer has the following features:

1. The top of the line notebooks can be very expensive.

2. Notebook computers are light weight which allows you to carry it where ever you want.

3. The battery can last up to 4 hours.

4. Low profile which means it is ultra thin.

5. It has a built in modem and a network connection.

6. The screen size is about 12 inches to 14 inches.

7. The internal floppy drive is not present

8. It dose not allow you to utilize DVDs or CDs.

9. It only supports a minimal Graphic subsystem.

10. Its keyboard is just big enough to be functional.

Laptop Computers

As the name suggests, it is a portable unit meant for you to be able to work with while resting on your lap. If we compare it with the Notebook it is quite large and has lots of power with several features. The design of the laptop gives you all the capabilities of a desktop computer yet remains mobile.

The standard Laptop should have most if not all the following features:

1. Laptops usually are a bigger than notebook computers.

2. They are a little bit heavier than Notebook.

3. Laptops are equip with ATI Radeon or Nvidia GeForce subsystem

4. It has an internal DVD-RW drive.

5. Integrated modem.

6. It has a Wi-Fi and network capabilities.

7. The battery can live up to 2 hours.

8. It has a large keyboard for your convenience.

9. The screen size is at least 14 inches to 17 inches.

10. You can even upgrade your laptops.

As you can see from the above information, there are many similarities as well as differences that exist between a notebook and laptop. I hope that this might help you.

Info about ARP Cache

Zaheer Ahmed Khan — Fri, 02 Apr 2010 15:28:03 +0000

ARP is a very necessary constituent of IP networking. ARP is essentially used to link OSI Layer 3, Network, to OSI Layer 2, Data-Link. In more simplistic terms, that means that ARP is used to connect our IP address to our Ethernet address or MAC Addressing. To permit communication with any device on your network, there must be an Ethernet MAC address for that device. If the device is not on a LAN, then a default gateway may be used or in other words a router. Where the router is used it becomes the destination MAC address that your PC will use to communicate .

There are two forms of ARP entries; these are static and dynamic. For the most part, dynamic ARP entries will be utilized. This simply means that the ARP entry, the Ethernet MAC to IP address link, is kept on a device for a relatively long duration of time, once it is being used. The static ARP entry contrasts with the dynamic ARP entry. When using a static ARP entry, the user manually entersthe link between the Ethernet MAC address and the IP address. Because of the tedious nature of using this method and the overall associated positives with using dynamic ARP entries, dynamic ARP entries are subsequently used more often than not.

To develop an ARP entry an ARP protocol is issued. For example if a PC wants to communicate with host www.thisisanexample.com. Before it can accomplish this task, it has to first resolve the hostname with the DNS server. If DNS resolves it successfully with an address of 111.112.111.112. before the PC can make actual contact with that IP address, it must then first resolve the IP address to the MAC address. To do this, it must perform an ARP request. This is a broadcast that goes to the local LAN that will try to assess who has IP address 111.112.111.112 and what is the Ethernet MAC address. If server replies and says I have IP address 111.112.111.112 and my MAC address is 1234.4567.890B the PC will place that entry into its local ARP cache and it will remain there until the entry has not been used and the ARP cache timeout has expired.

In addition, there is also the Inverse ARP protocol. This protocol executes the opposing task that the ARP protocol performs. Inverse ARP will ask all devices if they have the MAC address xxxx.xxxx.xxxx and, if so, what the specific device’s IP address is.

Regardless of the IP device being used, it will have an ARP cache. This ARP cache can be used for troubleshooting of network connectivity. If the ARP is working as it should and at optimum performance, a user will have a dynamic ARP entry that is complete with both MAC and IP values being available. If a user does not have a complete entry, he or she can clear the ARP cache and attempt communication once more by pinging the device with which the user wishes to communicate.

Steps to Prevent PC Problems

Bilal Akram — Fri, 02 Apr 2010 11:09:24 +0000

One must say that it is the dream of every computer system owner that their PC will work as proficiently as it did when it was purchased.

1. Disk Cleanup

2. Disk Defragmenter
These utilities will clean and make your hard disk contiguous so that your computer becomes more efficient and prevents PC problems.

Windows Registry should be Clean

The Windows registry is like a database that stores all the critical setting information that your system requires for day to day functioning. Every time a software or hardware is installed or un-installed on your PC, its configuration information is added or deleted to your Windows registry. Many PC errors can trace their root to an unclean and bloated windows registry.

A regular registry scan and repair through a reliable registry scan tool will make your computer faster and less susceptible to PC errors. Some important tools which help you in keeping your registry clean and defragmented are System Mechanics 9, Tune-Up Utilities or Registry Mechanic.

Try to remove unnecessary Programs

Most of the time the applications or the programs which we use get older and obsolete, you should remove all the unwanted or unnecessary programs from your PC because they are just taking up space and may be using your system resources as well.

Similarly, some of the new programs like add-on browser tool bars may make internet surfing slower because these toolbars have a tendency to use a lot of space and make computers slower.

So, to boost the performance of your PC and to improve your Web browsing experience, it is recommended that you uninstall toolbars that you no longer.
