In a desktop computer, these resources include such things as the processor, memory, disk space and more (On a cell phone, they include the keypad, the screen, the address book, the phone dialer, the battery and the network connection). It provides a stable, consistent way for applications to deal with the hardware without having to know all the details of the hardware. Difference between Windows, Linux, and Mac OS: Windows – Windows series of operating systems have the obvious benefit of market ubiquity. extremely familiar and therefore easy to use the vast majority of software, hardware, support and training available is designed with Windows compatibility primarily in mind bundled with new PCs NT1110_Larry Meza_Module1_Lab Windows is designed to run on PCs, whether bought new or built cheaply Mac OS: Mac OS X is known for its excellent, intuitive user interface there are far fewer viruses written for the system making it less vulnerable to attack the system is very stable whilst maintaining high levels of performance impressive range of professional applications available OS X is also proprietary software users are forced to purchase Apple hardware...

Whether we are talking about marketing information, cost projections, accounting results, or internal quality reports, every company depends on knowledge to support its planning, decision-making, and control. So how does knowledge fit into the picture? The emergence of the field called knowledge management has highlighted some key propositions in the last 10 years or so. All organizations are storehouses of knowledge that operate in information-rich environments made up of people and things both inside and outside the organization itself Organizations organize, interpret, and evaluate this information to solve organizational problems Knowledge is the primary mechanism for processing and utilizing information People's brains are the key knowledge resource of any organization Codified knowledge stored in books, audio, videotapes, and computer systems can be an important knowledge resource as well There are organizational processes and strategies for IT management and management in general. Therefore, processes and strategies in particular can significantly enhance the ability of organizations to...
