A DNS server translates a human address like google.com into a numerical IP address so your computer can take you to the right site. Usually, this takes a few hundred milliseconds to complete so it’s barely noticeable, but over time, these milliseconds can really build up. Also, your ISP’s DNS server isn’t always reliable as witnessed by Comcast subscribers recently when their DNS server failed, leaving customers unable to access Google and other sites. By using OpenDNS and FastCache, you can solve the two problems of reliability and speed.
OpenDNS runs a distributed network of DNS servers so using it is more reliable. It filters out bad addresses so phishers and spammers can’t direct you to their site. OpenDNS also detects typos in the URLs you enter so entering craigslist.og leads you to craigslist.org.
A piece of software called FastCache takes care of the problem of speed. It stores the IP address that is returned by your DNS server so your computer doesn’t have to request it every time you want to go to a particular site, saving a few hundred milliseconds each time. Read More»

Jason The Visual Round Trip Analyzer was initially an internal Microsoft tool, which the Redmond company is now offering as a free download. Designed as a webpage performance visualizer and analyzer, according to the software company, Visual Round Trip Analyzer runs on top of Network Monitor 3.2 and is set up to offer a comprehensive perspective over the download of a specific webpage. The Redmond giant indicated that VRTA comes with support for Windows Vista RTM and SP1, Windows XP, Windows Server 2003 SP1 and Windows Server 2008.
“The Visual Round Trip Analyzer tool helps web developers and testers visualize the download of their page, identify best practices and changes that improve performance. The Round-Trip between the client and server(s) is the single biggest impact to web page performance – much greater than server response time. VRTA examines the communications protocol, identifying the causes of excessive round-trips, and recommending solutions,” Microsoft informed. Read More»

Jason It is recommend for you to have a secure connection network between your PC and the Gmail server. Let say if you login to Gmail using a public network like wireless or hotspot in Starbucks, someone can tamper or see the sensitive information transferred from your PC to the Gmail server. This is because the network you are using is not secure and is open to everybody.
Non-secure networks make it easier for someone to impersonate you and gain full access to your Google account, including any sensitive data it may contain like bank statements or online log-in credentials.
To check whether you are in a secure connection or not, check that the protocol that being used is https at the address bar. And also, there is a Lock icon at the bottom right corner of your browser (Firefox).
When you have both of them, that’s mean you are in a secure connection. No one can tamper or modify or spying on the data transferred between you and the Gmail server. You are now safe and secure to send emails, at least. Read More»

Gmail recently became more secure for users and now you can use the Gmail SSL (Secure Socket Layer) feature to enable HTTPS for a more secure connection online while accessing your email. But you have to enable the setting…
Secure Gmail Connection
How to enable default secure Gmail connection?
Login to Gmail > Go to Settings > General > Browser Connection
Browser Connection set to https will force a secure connection and is essential to keep your data safe and protect it from hijacking. It is essential particularly for those accessing Internet and gmail via public Wifi or non-encrypted networks. So if you routinely login via wireless internet at coffee shops, airports, college dorms, then you might need this additional layer of security.
But I see https when I login?
Gmail uses https to protect your password every time you log into Gmail, but they don’t use https once you’re in your mail unless you enable this setting. Read More»

TCP/IP, an acronym for Transmission Control Protocol/Internet Protocol, is a suite of protocols supported by Microsoft with the Windows family of platforms. Essentially, through its components, TCP/IP is used for communications on both private networks and on the Internet. As far as the world wide web is concerned, the most common aspects of TCP/IP are IPv4 (Internet Protocol version 4) and IPv6. The Redmond company is offering extensive documentation on TCP/IP as it is supported in Windows Vista, Windows Server 2008, Windows Server 2003 and Window XP. TCP/IP Fundamentals for Microsoft Windows is available for download.
“This online book is a structured, introductory approach to the basic concepts and principles of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite, how the most important protocols function, and their basic configuration in the Microsoft Windows Vista, Windows Server 2008, Windows XP, and Windows Server 2003 families of operating systems,” revealed Keith Combs, Microsoft IT Pro Evangelist, citing an excerpt of the documentation’s description.
