Cisco Internetwork Operating System (IOS) has been around since a little after the inception of Cisco Systems as a company. In 1984, Len and Sandy Bosack from Stanford University founded Cisco Systems with a small commercial gateway server. The first Cisco router that I touched was an Advanced Gateway Server (AGS), which was the first marketed product of the company. After this came the Mid-Range Gateway Server (MGS), the Compact Gateway Server (CGS) and later the Integrated Gateway Server (IGS) and AGS+. The first version of IOS that I touched was 8.2(7). The operating system was based on a Unix-based system and was designed as a monolithic operating system, meaning that processes are stacked and interrelated.

Organizations are moving strongly toward Bring Your Own Device (BYOD) access, bringing outsourced activities back in-house, and finding ways to make use of the growing amounts of data flowing in from many new sources such as social media. These factors create an increasing shift in required and desired skills showing up in IT departments. Hiring and salary surveys, such as the 2014 IT Skills and Salary Survey from Global Knowledge and Windows IP Pro, TEKsystems' 2014 Annual IT Forecast, Foote Research Group's 2014 IT Skills and Certifications Pay Index, Computerworld's annual Forecast survey, Robert Half Technology Survey, and information from the US Bureau of Labor Statistics, Futurestep, Mondo, GovLoop, and Dice have presented a developing picture of the IT skills that will be in demand in 2014. Here, in survey order, are the top 10 major skills and why they made the list.

Self-awareness is a very powerful tool for leaders in every type of business or organization. The more leaders can maximize their self awareness the greater the impact on business performance, employee engagement and leadership and development initiatives. Self-awareness is the central component of personal development and emotional intelligence. For most leaders today it is still underdeveloped and frequently underemployed. Better understanding of this important leadership trait is critical for leadership and organizational success.

This webinar introduces the concept of resilient leadership. Leaders who can adapt not only support their organizations through ongoing change, but they also maintain high- performing and engaged teams in the process

A shift is occurring in the way we view leadership today. If you want to get things done, you need influence, not authority. This means that IT Professionals, Project Managers, Business Analysts, business-line Managers and individual contributors must focus on demonstrating personal leadership. Getting results through others by building relationships and using influence skills rather than relying on positional power is key.

In 2013, Cisco released their Software Defined Networking (SDN) solution for the data center known as Cisco Application Centric Infrastructure (ACI). For many years, the networking industry has been asking for an approach to configuring networking devices more efficiently than having to individually configure each and every router and switch.

IT professionals benefit from gaining skills in data analysis, cybersecurity, cloud computing, virtualization and hyperconvergence, and mobile app development.

A range of factors can influence the data center you choose. You should consider all of the factors listed in this white paper before deciding where to place your servers.

To understand the difference between Ethernet II and 802.3, you first must know how Ethernet works. While Ethernet cables transmit data, their role is relatively simple compared to that of the Ethernet card — also referred to as an adapter. It’s within the function of this card that you find the differences between Ethernet II and 802.3.
