Critical thinking allows us to take control of our thinking rather than letting it become hijacked by convenience, mindset, assumptions and bias. This white paper will walk you through understanding the implications of inputs (data) and influences (bias) to the reasoning process. You will learn how to develop a questioning outlook and quality standards that will lead you to make more effective decisions.
Linking business analysis skills with the methods of The Open Group’s Architecture Framework, TOGAF®, facilitates stronger IT results that drive business value.
Moving data from one networked device to another requires several different functions. Each function has its own protocol or protocols that define how it is accomplished. Also, the process of delivering data from one device to another can vary. The main factor in data delivery is determining whether the two devices are directly connected or remotely connected.

Change is the order of the day, and if anything, the pace of business and technology change is accelerating. The business and customers are looking to IT service providers to be more responsive, delivering more frequent service changes with higher quality-resulting in services that deliver more value to the business. In order to continue to be relevant and of high value, ITIL must continue to benefit from other complementary best-practices for IT. DevOps, an approach that encourages improved communication, collaboration, and teamwork across development and operations, can have a positive influence in improving ITIL processes across the service life-cycle.
Like it or not, Internet of Things (IoT) is upon us. There are a number of factors that will impact its adoption rate, and the inevitable privacy (or lack of) discussions will likely happen sooner than later. This is going to change the world as we know it, in many cases for the better. But we will need to keep an eye on the extent to which it invades our personal lives if it is going to be the positive force it has the potential to be.
For 10 years, Global Knowledge has surveyed IT professionals and published the findings in our annual IT Skills and Salary Report. With topics ranging from top-paying certifications to most in-demand skills, our reports have consistently provided a deep examination of the attitudes and opinions held by IT professionals around the globe. With a decade of reporting at our fingertips, we decided it was an appropriate time to dissect the views of those making the decisions in the tech industry. What are their biggest challenges? How have their training opinions changed over time? How do their actions affect staff?
IT architecture is undergoing a period of rapid change and evolution. With this change comes enormous opportunity for professionals who are not just deep in a single technology but deeply conversant in several and who can join these technologies together to meet the needs of today's enterprise. The Red Hat Certified Architect program provides a credential that represents these skills and knowledge. Through a combination of flexible requirements and recommended concentrations, Red Hat is providing a path for professionals to advance their careers and for its subscription customers to find the right architect.
Cisco Access Control Lists (ACLs) are used in nearly all product lines for several purposes, including filtering packets (data traffic) as it crosses from an inbound port to an outbound port on a router or switch, defining classes of traffic, and restricting access to devices or services. Knowing how to design, configure, and troubleshoot ACLs is required for all network engineers working within a Cisco network.
While the Internet uses IP addresses assigned by an Internet authority such as the American Registry for Internet Numbers (ARIN), there are too few of these numbers to uniquely identify the millions of computers and computing devices in the world. Therefore, most enterprises use private addresses which allow them to identify the aforementioned computers. Of course, these IP numbers cannot be allowed on the Internet because all private networks use the same ones so there would be vast overlapping of addresses, and the addresses are not compliant anyway. Therefore, it is necessary to change the identity of a private host to a legal public host. This process is called Network Address Translation (NAT) and may be implemented on Cisco firewall products and Cisco routers. The firewall device(s) at the Internet demarcation point is by far the more popular way to implement NAT, but routers are used in small offices or small-to-medium-sized networks in which a separate firewalling solution is not possible or affordable. The focus of this paper is on the router-based NAT solution.
