HTML5 New Elements

New Elements in HTML5

The internet, and the use of the internet, has changed a lot since HTML 4.01 became a standard in 1999.
Today, several elements in HTML 4.01 are obsolete, never used, or not used the way they were intended. All those elements are removed or re-written in HTML5.
To better handle today's internet use, HTML5 also includes new elements for drawing graphics, adding media content, better page structure, better form handling, and several APIs to drag/drop elements, find Geolocation, include web storage, application cache, web workers, etc.

Install Windows 8.1 Preview in a dual-boot configuration using a VHD

Install Windows 8.1 Preview

Are you interested in taking a look at the Windows 8.1 Preview? If so, then you'll want to know that when it comes to experimenting with Beta software, the best approach is to install it on your Windows 8 system in a dual-boot configuration using a VHD (Virtual Hard Disk).

When you use a VHD in a dual-boot configuration, you really get the best environment on which to experiment with the Windows 8.1 Preview. First, you will not have to mess with repartitioning your hard disk because the VHD exists as a file. Second, even though the hard disk is virtualized, you will get full benefit of your physical hardware such as the video card, USB connections, and amount of RAM. Third, when you are done experimenting with the operating system, undoing the dual-boot configuration as easy as deleting the boot entry and the VHD file.

What is 802.11ac ?

802.11ac is a brand new, soon-to-be-ratified wireless networking standard under the IEEE 802.11 protocol. 802.11ac is the latest in a long line of protocols that started in 1999:
  • 802.11b provides up to 11 Mb/s per radio in the 2.4 GHz spectrum. (1999)
  • 802.11a provides up to 54 Mb/s per radio in the 5 GHz spectrum. (1999)
  • 802.11g provides up to 54 Mb/s per radio in the 2.4 GHz spectrum (2003).
  • 802.11n provides up to 600 Mb/s per radio in the 2.4 GHz and 5.0 GHz spectrum. (2009)
  • 802.11ac provides up to 1000 Mb/s (multi-station) or 500 Mb/s (single-station) in the 5.0 GHz spectrum. (2013?)
802.11ac is a significant jump in technology and data-carrying capabilities. The following slide compares specifications of the 802.11n (current protocol) specifications with the proposed specs for 802.11ac.

Interview Questions for Network Support Technician


Q. Please describe the importance you place on customer service versus technical skills.
A. Most interviewers like to start with big picture questions and then work their way into more technical areas. IT is a service organization and customer service is at its core. In particular, customer service skills are just as important as technical skills, particularly in panic situations when systems are down or the user has just deleted their board presentation that’s due in 30 minutes. We’ve all had these situations. You should be prepared to talk about a specific situation where you’ve excelled and received accolades from an end-user. If they put it in writing, mention that as well.
