In this chapter, you’ll learn about the different operating systems, how they are designed and work, and what they do. You’ll learn about the different components of an OS and see how an OS provides the interface that users and applications need to command and use hardware devices. You’ll learn to use several Windows tools and utilities that are useful to examine a system, change desktop settings, and view and manage some hardware devices. As you work through this chapter, you’ll learn that computer systems contain both hardware and software and that it’s important for you as a computer technician to understand how they work together. Although the physical hardware is the visible part of a computer system, the software is the intelligence of the system that makes it possible for hardware components to work. 35 9781133726890, A+ Guide to Managing and Maintaining Your PC, Jean Andrews - © Cengage Learning.

...Microsoft Has Suddenly Gotten Serious with Mobile The Article’s overview Microsoft is showing that it wants to meet mobile users where they are, not where the company hopes they will be one day. Instead of using the strategy of pushing the mobile operation system in customer’s smartphones, Microsoft turned outside the company to bolster its mobile app offerings for Apple’s iOS and Google’s Android operating system. The reason for changing the strategy is that the company has figured out that Window’s mobile operating system dominates only three percent of the market share of mobile phone, while Android occupies the largest for 85% and iOS, the second, is at 11%. Initially, Microsoft attempted to compete with Apple and Google by buying the Nokia Company to put its own mobile operating system on the market as Windows Phone. Also, Microsoft did not make its software available for any competitors. However, this strategy never hurt any rivals, only Microsoft itself. With disappointing results, Microsoft has shifted its strategy and developed more applications and services and has brought them to Apple’s and Android’s devices. Early last year, Microsoft released the mobile version of Office 365 applications as well as OneDrive. They work well with other cloud storage apps such as Dropbox, Google Drive, or iCloud. Outlook is the latest application that was released in late January 2015. It is the email and calendar application for the heavy email users. Outlook is...

However, often the technological developments are working in the benefit of humankind evolution, but in the detriment of the nature. High-speed rails are a model of such solutions, meant to improve humans’ lives. Their high speeds (between 200 and 431 km/hour), and their easy boarding (the time spent in boarding is less than 30 minutes, depending on the travelling class), transform the meaning of travelling, making it a real experience. Moreover, the high-speed rails lead to indirect benefits such as allowing the possibility to travel for business purposes, or to working relocation. On the other hand, indirectly, high-speed rails create negative outcomes: urban agglomerations because of this efficient transportation mode, automatically lead to people deserting the rural regions, for...

Effective management of information technologies in an organization embraces the viewpoint that (1)most technologies reduce existing risk conditions. (2)technologies reduce some types of risks while introducing new types of risks to be managed. (3)technologies generally increase an organization’s overall net risks. (4)the objective of technology implementations is to increase profitability on a net basis. b. Which of the following is generally not considered a category of IT general controls? (1)Controls that determine whether a vendor number matches the pre-approved vendors in the vendor master file. (2)Controls that restrict system-wide access to programs and data. (3)Controls that oversee the acquisition of application software. (4)Controls that oversee the day-to-day operation of IT applications. c.

...rojects cost. Have you ever worked with a client who had a huge vision for a project, but had little capital to invest into the vision? Or have you worked with a client who gasped when you revealed how much it would cost to complete their desired scope of work? Or have you been fortunate and had a customer who accepted the costs for the project at face value, made certain the funds were available, and sent you on your way to complete the work? As a general rule, management and customers are always concerned with how much a project is going to cost in relation to how much a project is going to earn. Most likely there is more negotiating, questioning, and evaluating for larger projects than for smaller ones. The relation between the project cost and the project scope should be direct: you get what you pay for. Think it’s possible to buy a mansion at ranch home prices? Not likely. Think it’s possible to run a worldwide marketing campaign at the cost of a postcard mailer? Not likely. A realistic expectation of what a project will cost will give great weight to the project’s scope. As the business need undergoes analysis, progressive elaboration and estimates are completed based on varying levels of detail, and eventually the cost of project will emerge. Often, however, the predicted costs and the actual costs vary. Poor planning, skewed assumptions, and overly optimistic estimates all contribute to this. A successful project manager must be able to plan, predict,...

...The chapter analyzes and compares the investment incentives of platform and application developers for Linux and Windows. We find that the level of investment in applications is larger when the operating system is open source rather than proprietary. The comparison of the levels of investment in the operating systems depends, among others, on reputation effects and the number of developers. The chapter also develops a short case study comparing Windows and Linux and identifies new directions for open source software research. Keywords: Open Source Software, operating systems, technology platforms, Linux, innovation incentives. JEL Classification: L 10, L86, L3 1. 10.1 INTRODUCTION Open source software is an emerging type of software that may fundamentally affect the business and economic features of the software industry. Linux, an open source operating system, has been the prominent example of the potential of the open source movement, competing against Microsoft Windows, the incumbent operating system. 208 Nicholas Economides and Evangelos Katsamkas This chapter analyzes the incentives to invest in application software and an operating system under two different software ecosystems: one based on an open source operating system, such as Linux, and the other based on a proprietary operating system, such as Microsoft Windows. We build a model extending Economides and Katsamakas (2005) to compare the innovation incentives of application developers and operating system...
