When developing Windows 8, Microsoft made changes to the user interface in an apparent bet that most of its customers will be foregoing their traditional laptops and desktops in favor of tablets. This is probably a valid prediction for home users, but for businesses planning to stick with keyboards and mice for a while, there may be more user training than with Windows 7.

You work for Global Knowing Ledges. You are tasked to configure the addressing for the perimeter router. Use the network 172.16.0.0 255.255.0.0. After subnetting 4 bits, which of the following will configure the FastEthernet interface with the first host IP address of the fifth subnet and the Serial interface with the first host IP address of the sixth subnet. Use the zero subnet.

On my flight home from the Interop IT Expo and Conference 2012 in Las Vegas, I reflected on a great week of activities. I’m not talking about the free massages at the ViaWest booth, that cool orange Spiceworks shirt I never got my hands on, the cool Netscout tote that I got two of, or the great parties at Haze, Eye Candy Lounge, and the Foundation Room. Wait, of course I’m talking about them, because all those things were fun and cool and helped make the event great. But, here’s my more professional Top 5, in no particular order.

CompTIA released the latest revision and update to Network+ December 1, 2011. The new exam code N10-005 replaced N10-004, which was released in 2009. Generally, CompTIA revises and updates its collection of certification exams on a three-year cycle. The Network+ exam focuses on skills and knowledge of a general network technician. Network+ covers a broad spectrum of general networking knowledge ranging from networking devices to cables to protocols to networked software. It includes a reasonable balance of theory, configuration, implementation, architecture, and troubleshooting.

To wrap up this series on Cisco Career Certifications, we’ll finish with Data Center Specialist certifications.

Cloud isn’t a technology; it’s a business model. Cloud Computing is transforming IT and business alike. Because of this, many vendors now claim to be “as a service” or “cloud”. This series of posts explain exactly what Cloud is, how you get it, and what it does.

Cloud computing is a new business model powered by new technologies. It’s an on-demand, self-service, “pay as you go” model for access to hosting infrastructure (networks, servers, storage, operating systems, applications, support, administration). Cloud providers deliver infrastructure, platforms and applications as a service.

A major component of IT security is determining who is allowed into your structure both physically and logically, and what can they do once they have gained access? Access control determines who has how much access. To get control, organizations must lock down their systems, including hosts, networks, applications, data stores, and data flows, and address the following:

Communication Security
Cryptography
IDS/IPS/IDP
Logging and Monitoring
Penetration Testing
Remote Access

The underlying core of the Windows 8 operating system is polishing the code from its predecessors. Microsoft advises that legacy devices and applications should migrate fairly easily to Windows 8 and, in fact, a lot of them will simply work as-is, without an update. With all that being said, what is really new in Windows 8?

Your PC’s MAC address is 0010.1111.2222. Your PC gets its IPv6 address using stateless autoconfiguration. What is your PC’s EUI-64 format interface ID?

The term “Bytes” (which sounds like “bites”) was first to used in July 1956 by a PhD at IBM. He spelled it that way to keep typos of “bites” from becoming “bits”. The short answer is that bits measure the amount of data sent on a network, and bytes measure data stored in the computer […]
