INTRODUCTION TO OPERATING SYSTEMS THOMAS KRAWCZYK 03/23/2013 Over the past twenty or so years‚ there has been a never ending debate within the computing social realms‚ on whether software operating systems should be developed as open source or whether private companies should keep their source code closed from users of the software. This paper will define open source and closed source software models. In addition‚ a comparison between open source and closed source operating systems will be examined

UNIX By CIS 155 UNIX Operating System March 4‚ 2012 Abstract In the beginning‚ two men Ken Thompson and Dennis Ritchie in 1969 created an operating system that still has potential and relevance in today’s ever changing computer world‚ that operating system is called UNIX. I will be going over the past and present of UNIX and will also tell on how I feel about the future of UNIX. In the past‚ UNIX‚ a dominant operating system which pioneered the future of operating systems and how they are used

known malware are viruses‚ worms‚ Trojan horses‚ and spam. However‚ there are other forms of malware which are just as dangerous. A very hard type of malware to detect is called a rootkit. This form of malware will conceal itself within the operating system code to hide itself from detection. Rootkits may also hide itself within other programs. When installed‚ the attacker will now have access to the infected computer and view any file or carry out other attacks from the computer. This can be

all you could ever find inside the workplace‚ colleges‚ and at home. Until one day a new kind of computer was designed. This computer had a mouse with only one button on it and didn’t have a start button on the bottom left corner. At first these systems seemed very confusing‚ but as people began to use it‚ they found that it was simpler and more productive at work. This new design was called the iMac and it finally gave Microsoft some competition. Ever since then‚ Apple and Microsoft have both

These are operations available to the domain controller network system. This means that Window Server can centralize user and computer access. Only one machine needs to be configured as the Domain Controller rather than all machines on the network. Disadvantages The biggest issue that Windows Server has

Therefore‚ they contacted the boss of Micro Instrumentation and Telemetry Systems (MITS)‚ which create the microcomputer‚ told him about this‚ and the boss required them to demonstrate. BASIC‚ as its name means‚ was one of the most simple but high-level programming language to write and design software. Gates and Allen had done
