    One test of the vigor of the systems analyst role is that of demand. What is the current job market and what are the future employment prospects for the systems analyst? How do these compare with past? A recent study by Smolkina (2001) indicates that employment of systems analyst is projected to rank in the top twenty in the number of new jobs and is expected to increase over one hundred per cent over the next twenty years. In that study it was revealed that employment in computer and data processing services grew by more than 900,000 jobs from 1988 to 1998. In 1998, there were about 1.6 million wage and salary jobs, and an additional 216,000 self-employed workers, making it one of ...I... industries in the economy. Since the late 1980s, employment ...II... most rapidly in the computer programming services and prepackaged software segments of the industry. From 1988 to 1998, about 245,000 jobs were created in programming services and another 166,000 in prepackaged software. The study further revealed that the computer and data processing services industry has grown dramatically in recent years and employment is expected to grow about 117 percent by the year 2008, making this the fastest growing industry in the U.S. economy. The majority of workers in computer and data processing services are managers, professional specialists, such as computer systems analysts, engineers, and scientists; and technicians, such as computer programmers. Together, these occupational groups accounted for 70 percent of the jobs in the industry, reflecting the emphasis on high-level skills and  creativity. These statistics imply that the job title "Systems Analyst" is indeed ...III... and in fact is thriving (at least in name).

Internet Architects Warn of Risks in Ultrafast Networks

    If nothing else, Arista Networks proves that two people can make more than $1 billion each building the Internet and still be worried about its reliability.
    David Cheriton, a computer science professor at Stanford known for his skills in software design, and Andreas Bechtolsheim, one of the founders of Sun Microsystems, have committed $100 million of their money, and spent half that, to shake up the business of connecting computers in the Internet’s big computing centers.
    As the Arista founders say, the promise of having access to vast amounts of data instantly, anywhere, is matched by the threat of catastrophe. People are creating more data and moving it ever faster on computer networks. The fast networks allow people to pour much more of civilization online, including not just Facebook posts and every book ever written, but all music, live video calls, and most of the information technology behind modern business, into a worldwide “cloud” of data centers. The networks are designed so as to be always available, via phone, tablet, personal computer or an increasing array of connected devices.
    Statistics dictate that the vastly greater number of transactions among computers in a world 100 times faster than today will lead to a greater number of unpredictable accidents, with less time in between them.
    Mr. Bechtolsheim says that because of the Internet’s complexity, the global network is impossible to design without bugs. Very dangerous bugs, as he describes them, capable of halting commerce, destroying financial information or enabling hostile attacks by foreign powers.
    More transactions also mean more system attacks. Even though he says there is no turning back on the online society, Mr. Cheriton worries most about security hazards. “I ...... the claim that the Chinese military can take it down in 30 seconds, no one can prove me wrong,” he said.
    The common connection among computer servers, one gigabit per second, is giving way to 10-gigabit connections, because of improvements in semiconductor design and software. Speeds of 40 gigabits, even 100 gigabits, are now used for specialty purposes like consolidating huge data streams among hundreds of thousands of computers across the globe, and that technology is headed into the mainstream. An engineering standard for a terabit per second, 1,000 gigabits, is expected in about seven years.
