Operating system new and old one Essay Example | Topics and Well Written Essays - 500 words - 2

Operating system new and old one - Essay Example Indeed, the evolution of OS correlates with the growth in IT and computer needs. Examples of old operation system include Admiral Operating system for Honeywell 800/1800, Atlas I Supervisor that introduced system calls and virtual storage for the first computer. We also have the SCOPE operating systems developed in the 1960s that enabled batch processing and the MACE operating system for sharing time. The Michigan Terminal System (MTS) and MUSIC/SP are also examples of old OS developed for early computers like IBM. However, the complexity of new hardware and application programs led to the development of new OS. Indeed, the old OS lacked important features that are present in new OS such as the capacity to run third-party applications and multiple applications at once. Examples of new OS include Microsoft Windows, Android, IBM z/OS, Mac OS X, iOS, and Linux (Computer Hope 1). Most new OS adopt a touchscreen input design since it applies to portable devices. Notably, Microsoft Windows is the most dominant OS used in PCs, IBM, and smartphones (Computer Hope 1). The Apple Mac OS applies only in Apple computer operating system and on Macintosh computers while Android OS is applicable in all Android compatible phones (Computer Hope 1). Moreover, Linux is a new OS applicable in PC and IBM compatible computers while iOS operates with the Apple iPhone (Computer Hope 1). Notably, the choice of an OS depends on the hardware though all operating systems offer a graphical user interface that entails a des ktop and the capacity to manage files and folders. The early OS embraced diversity where technicians produced multiple OS to apply in a specific mainframe computer. However, the old OS had different command models, operating protocols, and operating tools. The development of new computers and hardware resulted to the introduction of new OS where the technicians adjusted, retested, and restructured the applications to accommodate the new OS. The new OS

Causes of Structural Failure Essay Example | Topics and Well Written Essays - 500 words

Causes of Structural Failure - Essay Example FitzSimons names "four horsemen of engineering apocalypse" or the factors which causes structural failures: ignorance, incompetence, negligence, and avarice (Carper 10). It should be noted that almost all the aforementioned factors solely attribute failures to engineers. In this regard, it is extremely important to clarify that human errors strongly contribute to the possibility and occurrence of structural failures. Oftentimes engineers make choices which can bring harm and inefficiency in the long run. 3. Design errors involve discrepancy in "concept, lack of redundancy, failure to consider a load or combination of loads, connection details, calculation errors, misuse of computer software, detailing problems including selection of incompatible materials or assemblies which are not constructable, and failure to consider maintenance requirements and durability, and inadequate or inconsistent specification or quality of work;" Any or combination of the aforementioned factors always leads to structural failures. Take, for instance, the failure of hydroelectric project. Investigation may often conclude that this problem arise because of different factors. The failure might involve mechanical and electrical problems, couple with operational errors, design concept deficiencies, and structural errors.
