Information Systems
Describe some reasons why Linux is installed on only a very small fraction of desktop computers. Are there particular categories of products or users who might see Linux as more appealing than conventional operating systems? Do you think Linux's share of the desktop market will increase? Why or why not?
Linux is less prevalent on server systems than desktops, as the latter type of systems have been the primary focus of much of the innovation with open source software. Desktop systems are lagging server adoption of open source due to the entrenched mature of competition from Microsoft and their Windows operating system, lack of consistent approach to defining office automation applications that can challenge the 80%+ market share of Microsoft Office, and the proliferation of 3rd party applications on the Microsoft operating systems in this market (West, Dedrick, 2006). Linux is far more dominant on servers, where open source has become a de facto standard for web services and advanced programming tasks (Orr, 2008). The pace of innovation on Linux server platforms continues to accelerate while desktop PCs and their operating systems are being cannibalized by tablets running the Apple iOS and Google Android operating system. This competitive dynamic is accelerating the pace of consolidation of desktop operating system as well, which makes Linux developers concentrate more on servers as a more viable, potentially profitable market.
Typically programmers and technical professionals are the primary users...
Members of technical professions see significant value in Linux as an operating system that can tailor to their specific needs and requirements. This is however a very small proportion of percentage of the total PC customer base, which is another factor that limits Linux acceptance and use as a desktop operating system.
As a result of all these factors, it is unlikely Linux will become a significant proportion of the desktop operating system market globally. Desktop PCs are under price pressure from tablets including the iPad and the desktop operating system market and applications area is also consolidating.
2) What are some of the benefits of cloud computing? What are some of the drawbacks? Find an article about cloud computing online. Summarize and critique the article in your own words. Be sure to include the url of the article.
The benefits of cloud computing include the ability to better align Information Technologies (IT) to business strategies, greater flexibility in aligning software features and design to user needs, often more rapid delivery timeframes, and flexibility in financing how the software is paid for using operating expenses (OPEX). These benefits are together changing the economics of enterprise software. The drawbacks of cloud computing is the risk of data being stolen or corrupted, lack of control over the data once it is on a remote server, and cost increases that can often occur for incremental services. In the article CIOs On Cloud…

" (Doukas, Maglogiannis and Kormentzas, 2006) The following illustration shows the evaluation Platform Architecture. Figure 3 The Evaluation Platform Architecture Doukas, Maglogiannis and Kormentzas (2006) state that the patient state vital signs are monitored through a PDA device attached to the patient and transmitted to a computer for evaluation through wireless access or Bluetooth. Additionally the patient site is monitored through use of a camera. The software that has been developed is used
Linux Security Technologies The continued popularity and rapid growth of open source software in general and the Linux operating system specifically are having a disruptive impact on proprietary software. The disruptive impacts of open source software are so pervasive that they are completely re-ordering the enterprise system strategies in many corporations globally today (Rooney, 2004). With this proliferation of open source software and the foundation being laid by the Linux operating
Risk analysis projects are relatively expensive, and were so even in the mainframe computing era, because they involved the collection and evaluation of a significant volume of data. Earlier risk studies were conducted by in house staff or consultants and the in house people did not have much experience regarding the matter and the consultants did not know much about the requirements of the organization. Presently, the familiarization task has
Another factor in open source database vendors leading this area is the focus on multiple models for scalability as can be seen in Table 1: DBMS Features Analysis. The support of multiple models of scalability also concentrates on OLTP transaction integration specifically within roles as defined in the security model (Pereira, Muppavarapu, Chung, 2006). Security will be discussed later in this analysis. The second factor used to evaluate closed source
UNIX Systems have been instrumental in the information systems management of corporations and organizations for many years. Although in recent years it has been overshadowed by other operating systems, it still remains as an alternative to other systems. The purpose of this discussion is to describe the benefits and problems associated with UNIX systems. The most beneficial aspects of UNIX are the robust nature of the system and the ability to
