Category Category v t e Computer operating systems (OSes) provide a set of functions needed and used by most application programs on a computer, and the linkages needed to control and synchronize computer hardware. On the first computers, with no operating system, every program needed the full hardware specification to run correctly and perform standard tasks, and its own drivers for peripheral devices like printers and punched paper card readers.

...1. What did Richard Stallman mean when he stated that GNU was a free operating system? Richard Stallman meant that his intention was that nobody would have to pay for “permission” to use the GNU system. He learned to distinguish carefully between “free” in the sense of freedom and “free” in the sense of price. Free software is software that users have the freedom to distribute and change. 2. Describe the relationship between Linux and the GNU Project. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux. 3. List and describe in detail four advantages of Linux. Applications – Linux is both free and commercial as well as a wide variety of tools: graphical, word processing, networking, security administration, Web server and many others. Flexibility - Linux can be used for high performance server applications, desktop applications, and embedded systems. You can save disk space by only installing the components needed for a particular use. You can restrict the use of specific computers by installing for example only selected office applications instead...

...rP os t 9-699-022 REV: MAY 6, 2002 ROBERT D. AUSTIN RICHARD L. NOLAN MARK J. COTTELEER Cisco Systems, Inc.: Implementing ERP History of Cisco op yo Pete Solvik, Cisco Systems chief information officer (CIO), considered the last remaining line item of his ERP (Enterprise Resource Planning) implementation budget. Cisco had a history of rewarding performance with cash bonuses, but the amount allocated for rewarding the ERP team, over $200,000, was unprecedented. To be sure, they had delivered a lot in a time frame that no one had believed possible. It had not been easy either. The team members, Solvik included, had taken a risk in joining the project. Rewards should, and would, be generous. The size of the bonus pool, though, made Solvik think: they had done well, but how well? What had gone right? What had gone wrong? Given another project of this magnitude and risk, would they be able to do it again? No tC Cisco Systems, Inc. was founded by two Stanford computer scientists in 1984 and became publicly traded in 1990. The company’s primary product is the “router,” the combination of hardware and software that acts as a traffic cop on the complex TCP/IP1 networks that make up the Internet (as well as corporate “Intranets”). With the rise of Internet technologies, demand for Cisco’s products boomed and the company soon began to dominate its markets. By 1997, its first year on the Fortune 500, Cisco ranked among the top five companies in...

...The Jobs family Steve Jobs was born on February 24, 1955, in the city of San Francisco. His Biological mother was an unwed graduate student named Joanne Simpson, and his biological father was either a political science or mathematics professor, a native Syrian named Abdulfattah John Jandali. In 1950s, the baby was put up for adoption. Joanne had a college education, and she insisted that the future parents of her boy be just as well educated. Unfortunately, the candidates, Paul and Clara Jobs, did not meet her expectations: they were a lower-middle class couple that had settled in the Bay Area after the war. Paul was a machinist from the Midwest who had not even graduated from high school. In the end, Joanne agreed to have her baby adopted by them. Paul and Clara called their new son Steven Paul. While Steve was still a toddler, the couple moved to the Santa Clara County, later to be known as Silicon Valley. They adopted another baby, a girl called Patti, three years later in 1958. Childhood Steve was quite a turbulent child. He really didn’t care about school for some time — until he reached the 4th grade, and had Imogene “Teddy” Hill as a teacher. She did bribe him, with candy and $5 bills from her own money. He quickly became hooked — so much so that he skipped the 5th grade and went straight to middle school, namely Crittenden Middle School. It was in a poor area. Most kids did not work much there, they were rather fond of bullying other kids, such as the young Steve....
