This was the beginning of long term experimentation and development to evolve and mature the Internet concepts and technology. Beginning with the first three networks (ARPANET, Packet Radio, and Packet Satellite) and their initial research communities, the experimental environment has grown to incorporate essentially every form of network and a very broad-based research and development community. [REK78] With each expansion has come new challenges.
Widespread development of LANS, PCs and workstations in the 1980s allowed the nascent Internet to flourish. Ethernet technology, developed by Bob Metcalfe at Xerox PARC in 1973, is now probably the dominant network technology in the Internet and PCs and workstations the dominant computers. This change from having a few networks with a modest number of time-shared hosts (the original ARPANET model) to having many networks has resulted in a number of new concepts and changes to the underlying technology. First, it resulted in the definition of three network classes (A, B, and C) to accommodate the range of networks. Class A represented large national scale networks (small number of networks with large numbers of hosts); Class B represented regional scale networks; and Class C represented local area networks (large number of networks with relatively few hosts).
Thus, by 1985, Internet was already well established as a technology supporting a broad community of researchers and developers, and was beginning to be used by other communities for daily computer communications. Electronic mail was being used broadly across several communities, often with different systems, but interconnection between different mail systems was demonstrating the utility of broad based electronic communications between people.
The Internet is as much a collection of communities as a collection of technologies, and its success is largely attributable to both satisfying basic community needs as well as utilizing the community in an effective way to push the infrastructure forward. This community spirit has a long history beginning with the early ARPANET. The early ARPANET researchers worked as a close-knit community to accomplish the initial demonstrations of packet switching technology described earlier. Likewise, the Packet Satellite, Packet Radio and several other DARPA computer science research programs were multi-contractor collaborative activities that heavily used whatever available mechanisms there were to coordinate their efforts, starting with electronic mail and adding file sharing, remote access, and eventually World Wide Web capabilities. Each of these programs formed a working group, starting with the ARPANET Network Working Group. Because of the unique role that ARPANET played as an infrastructure supporting the various research programs, as the Internet started to evolve, the Network Working Group evolved into Internet Working Group.
The Internet has changed much in the two decades since it came into existence. It was conceived in the era of time-sharing, but has survived into the era of personal computers, client-server and peer-to-peer computing, and the network computer. It was designed before LANs existed, but has accommodated that new network technology, as well as the more recent ATM and frame switched services. It was envisioned as supporting a range of functions from file sharing and remote login to resource sharing and collaboration, and has spawned electronic mail and more recently the World Wide Web. But most important, it started as the creation of a small band of dedicated researchers, and has grown to be a commercial success with billions of dollars of annual investment.
A career can be defined as a person's progress within an occupation or series of occupations. However, a career is more than just a job, or working, or your occupation. It also includes your progress through life, your growth and development in vocational and avocational areas of life.
Many of us think that there is only one occupation that is best suited for us, but there are really several that may be good choices. The secret is to identify those occupations in which you have a high probability for success and happiness. As a college student, whether your career goals are accounting, theatre arts, or environmental sciences, there are general skills which will be required regardless of the career you pursue. These skills include the ability to read, write, compute, think critically, and communicate in an effective manner. For the most part, these skills are developed and/or sharpened in general education courses. These skills, along with effective career planning techniques, and the ability to cope with ambiguity in a changing environment, will enable you to overcome obstacles throughout your work life.
What you will do for a living depends a lot on who you are. This may sound obvious, but many people neglect considering this important side of selecting a career. You can avoid joining the ranks of people who are dissatisfied with their work by making a conscious effort to assess yourself. There is no way you can be absolutely certain that a career will meet all of your needs, but there are things you can do very easily that will help you learn more about who you are. Once mastered, techniques of self-assessment can be repeated throughout your life.
It is difficult, if not impossible, to make a rational decision or to evaluate and consider specific careers without an accurate information base. Career information gathering is an integral step in the process of career planning. Initially, you will need to generate a list of careers which you may want to consider. The federal government lists more than 31,000 career fields. Most students admit they have limited knowledge about careers and find it difficult to list or describe more than 40. Sources of career alternatives include the results of computer assessments such as MyPlan, paper and pencil assessments, career publications and suggestions from other people such as faculty and staff, parents and friends. Don't forget to take into account those careers you are merely curious about exploring. After developing the list, you will need to briefly research each career alternative and judge which of these seem potentially suitable for future employment. Determine for each: typical on-the-job duties, qualifications, outlook, salary, methods of entry, etc. How do your skills, values and interests correspond to the types of work you are considering?
In times of rapid change and rampant obsolescence in occupation fields, you must remain flexible. The "one-job, one-career worklife" of a generation ago phenomenon has been increasingly replaced by a "12-jobs, four-careers worklife." At some point you may begin to ask questions of yourself about your present employment. You may wonder whether there is something better available; or as your skills, values, and interests change, whether another position would better meet these factors. If and when this occurs, the career planning process has completed its cycle. You can return to Step 1: Self Assessment and begin anew the process, anytime during your working years as often as you desire. Remember, the key to success is being prepared.

Industry 4.0 is bringing about the convergence of information technology (IT) and operational technology (OT) systems, creating interconnectivity between autonomous manufacturing equipment and broader computer systems. OT data from sensors, PLCs and SCADA systems is being integrated with IT data from MES and ERP systems. Augmented by machine learning, this integration impacts the entire enterprise, from engineering to operations, sales and quality.
Focus on the main concepts, avoiding words that are vague or implied. For example, using a general term like "affect" can greatly limit your results. First, an author may only use words for a single, specific effect (e.g. technology use raises student achievement). Second, there are many alternative phrasings that can look at the effects of something (e.g. impact, result, consequence, etc.), and it's unlikely you'll be able to brainstorm them all. You'll get better results if you brainstorm specific effects (e.g. academic achievement) instead of using "affect/effect" as a keyword.
Historically, the field of computer engineering has been widely viewed as "designing computers." In reality, the design of computers themselves has been the province of relatively few highly skilled engineers whose goal was to push forward the limits of computer and microelectronics technology. The successful miniaturization of silicon devices and their increased reliability as system building blocks has created an environment in which computers have replaced the more conventional electronic devices. These applications manifest themselves in the proliferation of mobile telephones, personal digital assistants, location-aware devices, digital cameras, and similar products. It also reveals itself in the myriad of applications involving embedded systems, namely those computing systems that appear in applications such as automobiles, large- scale electronic devices, and major appliances.
A strong and extensive foundation in mathematics provides the necessary basis for studies in computer engineering. This foundation must include both mathematical techniques and formal mathematical reasoning. Mathematics provides a language for working with ideas relevant to computer engineering, specific tools for analysis and verification, and a theoretical framework for understanding important concepts. For these reasons, mathematics content must be initiated early in the student's academic career, reinforced frequently, and integrated into the student's entire course of study. Curriculum content, pre- and co-requisite structures, and learning activities and laboratory assignments must be designed to reflect and support this framework. Specific mathematical content must include the principles and techniques of discrete structures; furthermore, students must master the established sequence in differential and integral calculus.
