Browser Security Safari 5.1

Many of the default settings in Safari are activated to protect you as soon as you open the browser, while others may require some modification depending on your preferences.

Privacy Options

Safari is designed to filter the data that outside parties can access as you surf the Web. Certain Web sites that you visit use your stored data to track where you browse, but you don’t have to let sites retain that information. Additionally, you can personalize your cookies (small files that Web sites store on your PC) and limit how often Web sites can request your physical location. To customize these settings, open Safari and click the drop-down arrow next to the Settings “cog” icon. Select Preferences and click Privacy. Under the Remove All Website Data button, you’ll see a number listed next to Websites Stored Cookies Or Other Data. To view these sites, click Details. Y can delete individual Web sites or all sites to reduce browser tracking. Select a site and click Remove to get rid of one site at a time; click Remove All to clear the entire list (alternatively, you can just click Remove All Website Data in the Privacy pane). In the same dialog box, there are three options to block cookies: From Third Parties And Advertisers, Always, and Never. Click the option you prefer. If you want to limit Web sites’ access to retrieve your location, click Prompt For Each Website Once Each Day, Prompt For Each Website One Time Only, or Deny Without Prompting. The Private AutoFill feature doesn’t automatically fill out online forms, unless you allow it to. But, this is a good thing. When you start typing your information in a Web form, Safari displays a drop-down field, giving you the choice to allow Private AutoFill to complete the form (using your personal information from Outlook or Windows Address Book) or fill it out one box at a time. You can configure your AutoFill Web forms by selecting the AutoFill pane in Preferences (via Settings). Safari will automatically fill forms using information from your address book card if you select the associated box. And when you select the boxes next to User Names And Passwords and Other Forms, Safari remembers your saved user names and passwords, as well as any Web sites that have stored your AutoFill data. Click the Edit button next to either option to remove the aforementioned information from each preference. Safari includes a third concealment feature called Private Browsing. If you’re using a public computer in a public workplace, and you prefer not to expose sensitive information to people who use the computer after you, the Private Browsing feature will protect your browsing history. (It won’t prevent Web sites that you visit from gathering information.) Safari will not keep track of Web sites visited, search history, or AutoFill data. To switch to this browsing mode, click the Settings icon and choose Private Browsing. Click OK in the Do You Want To Turn On Private Browsing? dialog box. Click OK. For the duration of your Private Browsing session, the Private icon appears in the Smart Address Field (the Address bar). To turn off Private Browsing, simply click the Private icon and click OK when Safari asks Are You Sure You Want To Turn Off Private Browsing?

EV Certificates

Some Web sites choose to add extra security (encryption or third-party verification) to their sites in order to protect against Internet fraud. For instance, financial institutions and other businesses want to ensure that customers who navigate to their sites will feel safe when entering sensitive data. The Safari browser supports EV (Extended Validation) certificates, so you can quickly recognize a legitimate Web site. To know if you’re at a site that’s been authenticated, look for the name of the Web site displayed in green on the right side of the Address bar. Click the name and the Certificate dialog box will open. The Certificate Information listed should include what the certificate is intended for, which site it’s issued to, which organization verified it (such as VeriSign), and how long the certificate is valid.

Reset & Empty

You can refresh Safari by actuating two settings: Reset Safari and Empty Cache. Reset Safari lets you erase particular items associated with your browsing patterns, whereas Empty Cache will clear memory (visited Web pages, images, etc.) if you want to remove the content Safari has saved. To locate both of these settings, click Edit in the Menu Bar. Select Reset Safari and the browser will ask you if you want to reset. You should see a checklist of items to reset; by default all of the items will be checked. Uncheck any you don’t intend to reset and click the Reset button. If you click Empty Cache in the Edit menu, Safari will prompt you to click Empty or Cancel.

Mobile Broadband Today

There’s good reason why many phones, tablets, and other mobile devices these days support a very non-mobile technology: Wi-Fi. In many parts of the U.S., as in many parts of the world, the 802.11b/g/n wireless networking standards simply offer better performance than nearby cell towers. Using Wi-Fi to tap into a business’s or home’s broadband Internet connection accelerates the downloads, uploads, streaming, and VoIP (Voice over Internet Protocol) that smartphones and tablets can do so well-as long as they’re not constrained by outdated, congested 3G technology. Of course, the problem with Wi-Fi is the fact that your fast, local connection drops back to your wireless broadband plan as soon as you leave your company’s parking lot. If you’re still using 3G wireless broadband, you’re missing out on a lot of the capabilities that current mobile devices have to offer, such as video phoning. Looked at another way, there are resources being underused, and that could mean missed opportunities for your business. The placement for 3G is, as you might guess, 4G. Short for fourth generation, 4G is the name of a collection of faster wireless standards for mobile broadband. It’s also a catchier name than IMT-Advanced (International Mobile Telecommunications-Advanced), which is the global network concept being developed by the ITU-R (International Telecommunication Union-Radiocommunication; IMT-Advanced/4G involves a variety of technologies meant to speed up data transmissions and make them more reliable, including MIMO (multiple input/ multiple output antennas), IP packet switching, and dynamic resource usage. There’s also support for IPv6 Internet addresses, as well as for seamless coverage as the user travels between different types of cell networks.

4G Today

Today, the major carriers advertise several wireless broadband technologies as “4G.” Depending on who’s doing the talking, 4G may be LTE (Long Term Evolution), WiMAX (Worldwide Interoperability for Microwave Access; 802.16), and/or HSPA+ (Evolved High-Speed Packet Access). Data rates average in the Mbps single digits, for the most part. Specifically, AT&T says that its HSPA+, an improvement on the 3G-era HSPA network technology, reaches 6Mbps. Sprint says that its WiMAX 4G system offers 3 to 6Mbps (megabits per second) speeds, while Verizon claims 5 to 12Mbps for its 4G LTE network. Finally, T-Mobile says that its 4G HSPA+ offering averages almost 10Mbps in download speeds with a 21Mbps peak transfer rate. Footnotes on the company’s site furthermore mention an augmented HSPA+ network with 42Mbps peak speeds in limited areas. These numbers are a far cry from the ITU-R’s initial goals for 4G, let alone the 128Mbps and 100Mbps theoretical maximums of current WiMAX and LTE technologies, respectively. Still, they’re definite improvements over the aging 3G, providing more speed and less latency. (Note that network speeds will drop when you’re moving quickly, such as in a car or on mass transit.)

Get It

In order to get 4G, you’ll need a phone, tablet, or other device that supports it. If your current phone or device is capable of using the 4G network of your current carrier, upgrading may be as easy as turning on the 4G radio in your phone’s settings. You might also have to run an update on your device for full compatibility. If your tablet, phone, or other device isn’t compatible with 4G—or at least the type of 4G offered in your area— you’ll need to change to a new mobile device. The easiest path here is to make the move to the one or device offered by your local 4G carrier of choice.


Future plans for 4G technology include a 1Gbps (gigabits per second) evolution of LTE called LTE Advanced, as well as a 1Gbps version of WiMAX called WirelessMAN-Advanced or 802.16m (WiMAX 2). For perspective, those are faster than the wired networks in many homes and businesses. It truly is an exciting time in mobile gadgetry.

How To Do Network Troubleshooting

Get Reconnected

Network access is more important than ever today. For example, cloud computing has made it possible to store our most important emails, documents, images, and other files on a server that we can access anywhere with Internet access. And some applications no longer include installation discs, because you’re expected to be able to download the program from the company’s Web site. As such, it can be a real pain when your network is down, slow, or unreliable.

General Troubleshooting

Two of the most common failure points with networks are your router and the modem. Las Vegas Computer repair – Fortunately, the router is one of the easiest computing devices to fix. Simply turn the router off and turn it back on. This is called power cycling. Often, power cycling the router will allow it to overcome bugs that have caused it to become unresponsive. For example, the router may have had an issue where it could no longer renew its IP address or release new IP addresses for the computers on your network. Power cycling is similar to restarting your computer, in that the software inside the router is restored to a known good state. Similarly, you may need to power cycle the cable,DSL (Digital Subscriber Line), or satellite modem connected to your router to reset the device’s software. If power cycling the router or modem didn’t help, your network adapter is the next component to troubleshoot. You can use the Network Diagnostic utility built into Windows to help find the problem. The Microsoft utility can automatically enable disabled network adapters or request that the router renew your computer’s IP address. To run Network Diagnostic in Windows 7, click the Start button, select Control Panel, choose Network And Internet, and select Network And Sharing Center. Under View Your Active Networks, select the link next to Connections and click the Diagnose button. Windows will run a few tests and may attempt to reset your network adapter. If the Network Diagnostic doesn’t find anything, it’s a good idea to try and reboot your computer. With a wired connection, you’ll also want to check that the Ethernet cable running between your computer and router is firmly connected on both ends. With a wireless connection that uses a USB adapter or PC card, you should also try to remove the wireless adapter d reinsert it to see if it was loose.

Wired Troubles


My network connection drops intermittently.


There are a variety of reasons you could experience this problem, but one of the more common causes is a problem with the driver for your wired network adapter. With most computers, the wired network port is built into the motherboard, rather than an add-on card, so the manufacturer of your computer or motherboard will provide downloadable drivers for the network adapter. It’s also possible that there’s a new driver available that’s been released to fix the problem you’re currently experiencing. If your computer doesn’t include a name or model number on the exterior, you can figure out who made the motherboard by using CPU-Z (free; from CPUID. On the CPU-Z Web site, click the download link under Download Latest Release and then click the Download Now button. When it finishes downloading, click the Run button and open the CPU-Z program. It will quickly scan the computer and tell you about the specific hardware on your computer. To find out the brand and model number of the motherboard, click the Mainboard tab and look in the Manufacturer and Model fields. Write down the motherboard manufacturer and visit the vendor’s Web site. For example, MSI’s Web site ( features a Downloads tab, which will link you to a page where you can enter MSI products to quickly find drivers, BIOS updates, firmware, and patches. MSI also offers a Live Update Online utility that will scan your PC for drivers and BIOS updates, so you can always keep them up-to-date. You’ll also want to check the physical network connections to see if everything is still securely connected. A connection that’s loose may explain why the connection drops intermittently. It’s possible that the cable may have a cut or kink that causes a fault in the connection. Try replacing the Ethernet cable with a new one, or one that you know works fine.


My connection is occasionally slow.

Google Public DNS

Why Google Public DNS?

As web pages become more complex and include more resources from multiple origin domains, clients need to perform multiple DNS lookups to render a single page. The average Internet user performs hundreds of DNS lookups each day, slowing down his or her browsing experience. As the web continues to grow, greater load is placed on existing DNS infrastructure.

Since Google’s search engine already crawls the web on a daily basis and in the process resolves and caches DNS information, we wanted to leverage our technology to experiment with new ways of addressing some of the existing DNS challenges around performance and security. We are offering the service to the public in the hope of achieving the following aims:

* Provide end users with an alternative to their current DNS service. Google Public DNS takes some new approaches that we believe offer more valid results, increased security, and, in most cases, better performance.
* Help reduce the load on ISPs’ DNS servers. By taking advantage of our global data-center and caching infrastructure, we can directly serve large numbers of user requests without having to query other DNS resolvers.
* Help make the web faster and more secure. We are launching this experimental service to test some new ways to approach DNS-related challenges. We hope to share what we learn with developers of DNS resolvers and the broader web community and get their feedback.
