How to Change Your IP Address

The IP or Internet Protocol address helps identifying the terminal that one is using when surfing on the internet while at the same time enabling one to trace their online activities. The Internet Service Providers or ISP controls the IP addresses. Changing an IP address is not something that can be done easily especially if it is done promptly because it takes a lengthy process. However, static IP addresses are assigned by some ISP which when it is needed to change, the ISP has to be contacted for technical support to get a new one. Various computer applications require different procedures to change an IP address.
Through the command prompt
The command based interface is the back end of the computer's operating system. When using the command prompt for changing the IP address, two options are available that can be used.
Option 1
Steps:
1. First, turn on the computer
2. Go to the Start button then Run
3. A small dialogue box will appear on the screen in which 'cmd' is to be typed. This will automatically pull up the command prompt.
4. Type 'ipconfig/release' then press Enter
5. Type 'ipconfig/renew' then press Enter
6. Now type exit to leave the prompt and return to the desktop
When 'ipconfig/renew' is typed, the modem will generate a new IP address.
Option 2
Steps:
1. Turn on the computer.
2. Click Start and Run then type 'cmd'.
3. Now type 'ipconfig/release' on the small box that appears on the screen.
4. Shut down the computer and turn it off.
5. Now, the switches and hubs are to be turned off.
6. Turn off the DSL modem and cable.
7. The computer should be left in that condition overnight.

How to Block Pop Up Ads

Pop up ads are of three different categories namely pop-ups created by spyware and adware, messengers service advertisement and general browser pop-ups. Pop-ups ads occasionally appear on the screen and interfere with the user's ability to view the contents displayed on the screen. The user can easily avoid these advertisements by installing a pop-up blocker.
Messenger service advertisement
These types of pop-ups are applicable only for Windows XP and Windows 2000. They usually occur because someone is accessible to your computer network and is can transmit this message to your computer through TCP and UDP ports. It is the responsibility of the messenger service to transmit these messages. For controlling these pop-ups, the security has to be hardened by installing firewall software like zone alarm or by installing Windows XP which puts off messenger service by default and activates the windows firewall. The port which facilitates the transmission of these messages gets blocked.
For activating firewall in Windows XP, click the Start icon on the desktop, press Run and type the word Firewall.cpl, select the on button lick OK. It is recommended not to connect to the internet before activating the Firewall because there is a risk of computer getting infected.
Pop-ups created by adware and spyware
The function is same as the general browser but spyware is usually run by the browser assistant object which is the activeX controls that connects to the internet explorer and gets in touch with their server without the user knowing it. This can also be a cause of leaking the user's confidential information to the spies as well as wasting the internet bandwidth. In relation with this, any outgoing connection without the user's authorization should be taken as threat to the security of the user. For preventing pop-ups that are generated by adware and spyware, anti-spyware application such as spyware blaster, Ad-Aware, Spybot Search and destroyer should be installed in the computer. They are just the same like the anti-virus software. These applications work by employing the services of the folders of the hosts for preventing unnecessary ads servers and sites that are responsible for conveying these ads, they also increase the security settings of the browser.
Applications like Sygate and Zone Alarm will always signal the user every time when an outgoing traffic is detected. This will enable the user to block Trojans and dialers from reaching the internet. It will also give the user same attentions to the settings of the firewall, it can be assumed as the passage security and operates only with programs that are needed to be assessable to the internet. This point will make the user be able to investigate the performance of the firewall being employed to the websites. They will do a thorough checking of the system for accessible ports and weaknesses, therefore they will accordingly advise the user.
General Guidelines that should be followed
- The system should not be connected to the internet before activating Anti-virus and firewall.
- The security configurations should be amplified in the browser so that the Activex control is blocked from installing automatically.
- The system should be always updated by seeking latest information online or by subscribing to Microsoft Security Bulletin in order to be aware of the possible threat.
- The services of the HOSTS folder should be employed for preventing unwanted websites.

CD-R For Long-Term Digital Storage of Photos, Audio, and More

Depending on your storage requirements, a CD-R or recordable CD can be an excellent choice for safeguarding your digital information. Digital files such as digital audio, digital photos that are not very high quality, emails, spreadsheets, and word processing files can all be stored quite well on the CD-R format. However, the capacity of the recordable CD is either 650 MB or 700 MB and because of this, there is not enough space to store significant amounts of digital video and at reasonably good quality. To store more than 15 minutes of digital video on a recordable CD would require heavy compression of the video and this would result in poor quality. Despite this limitation for digital video, the CD-R can be used for the effective storage of most other digital files.
There are various choices for CD-Rs that go beyond just selecting a particular brand. CD-Rs store information in a dye layer and there are three main types of dyes that are used. The three dyes are a phthalocyanine dye which is light green in color, a cyanine dye which is generally light blue in color, and an azo dye which is deep blue. The phthalocyanine dye is the most stable and does not degrade with elevated temperature or relative humidity and does not fade with light exposure. Both the cyanine and azo dyes are much less stable. These dyes are sensitive to degradation initiated by temperature and relative humidity and will fade with enough light exposure.
Another important part of the CD-R is the metal layer. The metal layer is found after the dye layer if looking at a cross-section of a disc from the bottom up. A disc is read through the base. The role of the metal is to reflect the laser light that reads the disc back to the player/reader detector after it reads the information in the dye layer. In order words, the metal layer is very important because it allows the laser light to produce a signal. Without the metal layer, the laser light would shine through the disc and no signal would be registered. There are three types of metal layers that are used in recordable CDs, silver, silver alloy, and gold. Gold is very stable and will not react. Silver will oxidize and corrode and so will silver alloy but to a lesser extent.
Therefore, if you want to store your information on very stable media, the recordable CD or CD-R with a gold metal layer and phthalocyanine dye is the best option. Choosing discs with other dyes and other metal layers can potentially give you much shorter lifetimes. Finally, it is also important to select discs that have a good scratch resistant top layer because this will help prevent irreversible physical damage to that all important metal layer.

How to Trace Hackers

Ever wondered how hackers function and what you can do to find someone that is hacking into your system. Read through the following article for some answers.
If you want to know how to trace hackers then you will find some answers in the following paragraphs. The first thing that they need, to be able to get into your system is your IP address. One way that can get your IP address is from the header information from emails that you send. Included in header information is the IP address of where the email is being sent from and once they have this they can access you.
Since there are now two kinds of IP addresses, the static and dynamic, hackers are generally able to access people with static IP addresses or using DSL lines. So if you are operating with dynamic IP addresses hackers are of little concern to you.
One way of how to trace hackers is to use a tool referred to as the NETSTAT tool. Using this tool you will be able to see who is connected to you. On your PC go to start, click programs, choose MSDOS prompt and then type in "netstat -a". There must be a between the last t and the a'. The screen will then display a list of active connections. It will show a local address, that is the address of your PC and the ones that they say foreign address are the ones that are connected to you.
There are various NETSTAT commands that will help you understand the workings of your network better. If you want to know how to trace hackers, I recommend that you learn as many of these commands as you can. Once you know them, then you are set.

What 4G Wireless Deployments Mean For America

The United States is a country with a proud tradition of technological innovation and advancement, and it is a country where ordinary people demand access to extraordinary technologies. Though the sheer size of our country sometimes makes it difficult to provide large-scale commercial access to cutting-edge technologies-more difficult, at least, than is the case for smaller countries with smaller populations such as the nations of Europe and Japan - we have nonetheless done an incredible job in this regard, as can be seen, for example, in the case of deployments of latest generation mobile networks. Across the United States there are new deployments of such technology being planned for the imminent future or already being conducted, and more people than ever before are going to be able to enjoy the advantages of super-fast wireless internet than ever before. Yet what are the specific benefits and advantages that the latest in mobile technology, 4G, actually offer America and its citizens? That is a question the answer to which is a little more complex and sophisticated than most people might think at first, and here we'd like to delve a little deeper into the subject to help people out there understand what it really means to have fourth generation wireless networks spreading out across the country.
Though it is still a little ways off, the spread of 4G networks across the land is going to entail an absolutely unprecedented level of coverage, eventually surely stretching from coast to coast. Wireless networks have traditionally focused on the major urban zones of the nation, yet this time around with the latest generation of mobile technology the rural areas of the nation are also going to be brought on board. In fact, providers that have already ventured into remote locations have detected that there is a surprisingly high capacity for acceptable return-on-investment rates in these areas, something which is completely the opposite of what had been originally expected. Though nationwide coverage for 4G networks is still a ways off (that won't last long), residents of places that have already been included in the coverage map will notice that the coverage area they are included is surprisingly vast. Rather than just the downtown area of the cities where such networks are deployed, the coverage area extends well out into the surrounding greater metropolitan area-something that is practically unheard of! The superior transmission capabilities of next generation mobile networks are responsible for this, and it is thanks to the fact that each cell is larger than ever before that bringing the entire country 4G coverage will be feasible in the midterm.
With regards to connection speeds, 4G wireless is going to offer Americans an experience that they will in most cases not even be ready for it's that fast. Currently fourth generation networks are able to bring users speeds that range anywhere from 8 to 15 Mbps, whereas in the very near future such speeds will steadily creep up to 50 Mbps and even beyond. As a result, mobile apps will become much more dynamic and offer capabilities never even heard of before on mobile devices.

See if clear internet hasn't already been deployed in your local area. With the strength of their wimax internet transmitting technology, soon everyone will be able to connect at next-generation speeds!
