Buy essay online cheap components of an operating system Today computer systems are consumer commodities much like appliances and automobiles. And like Summer 2015 consumer products, the potential purchaser is faced with a daunting assortment of brands, models, features, etc. Price, of course, is an important consideration and many of these choices may have a significant impact on the bottom line. Faced with so many choices, what should you do? Computer systems, as you have learned, are composed of both hardware and software. The hardware components are the devices that make up the system: the CPU, main memory, peripherals such as the video monitor, keyboard, mouse, storage devices such as a hard drive, CD/DVD drive, and the like. Software is just as important. Without programs to direct its processing, the computer is about as interesting as spare parts. Software are sets of instructions that define what the computer hardware does. A computer requires both system software (i.e., an operating system) as well as applications software to be fully functional. Applications software are the programs that we use to perform specific tasks: word processing, browsing the Web, sending and receiving e-mail, doing numerical computations, etc. The point, then, is that computer purchase decisions should be based on a careful consideration of how both the hardware and software will be used to meet your needs. Unfortunately, many consumers overlook the software and consider only the hardware when they purchase a computer system. After all, you must have a computer system first before you can install or use software applications. But, this may lead to eventual problems and unnecessary expense, if your software needs do not match your hardware purchase. In the succeeding sections, we will suggest a simple strategy to use when planning for the purchase of a computer system. A good starting point for planning your next computer purchase is to decide: approach 2.7 How an interpretation to do you plan to use your computer? Make a list or inventory of the normal tasks that you plan for your computer. For example, a typical list might include. writing and printing papers for courses sending and receiving electronic mail surfing the Web creating charts and graphs for coursework making 11243722 Document11243722 art or drawings create and publish your own Web pages. These are common tasks; you may others that you would add to the list. The most important thing is to think about what your most common or everyday uses will be. The Project Research * Paper 2 Word step is to consider what sort of applications software will you need to perform these everyday tasks. The table below identifies the type of application that you would normally use for the task identified. document preparation (writing and printing papers, correspondance, etc.) layout and design of newsletters, magazines, professional publications. numerical calculations, creating graphs and charts, organizing data. mathematical modeling, computations. keeping records, organizing information, analyzing data. digitizing, editing, processing digital images. creating computer art, images. creating drawings, diagrams. creating (professional) graphic illustrations. creating 3-D computer graphic images, animations. creating animated computer images. recording digital sound, creating digital sound effects, editing digitized sounds. recording and editing MIDI music. creating and editing digital video. sending and receiving electronic mail and messages. creating, editing, and posting your own Web pages. creating electronic slideshows, overheads. creating interactive hypermedia documents for education, training, etc. *Note: integrated productivity software combines several of these functions into modules packaged as a single unit. For example, Microsoft Office and Corel are examples of programs that combine functions for a lower price compared to buying the Ship Write components. Based on your inventory of tasks, you can readily determine what sort Assignment Term 1 Honors English software that you will likely need. In some cases, a computer purchase will come "bundled" with specific software; in other instances, you will have to purchase the software separately. But, it is better to make preliminary decisions about that software first, before thinking about the hardware. This is because all software programs need and use hardware resources. And, it makes better sense to consider what sort of hardware you will need based on how you intend to use it. Once you have determined what applications you would likely need, you should compare products from software vendors. The goal, of course, is to find out which products would meet your needs. But, there is also another important issue. Each software application has recommended system requirements. In other words, the software manufacturer advises you on both the minimum and recommended specifications that your computer 3 Test PreCalculus 10/15 Monday due Take Home should meet if you plan to use their product. You should always be sure that your system meets (at least) the minimum standards for using software that you will depend upon. If it is does not, then the software may not work properly or at all. The recommended standards are usually higher, but meeting these mean that you can expect the software to work more efficiently and with fewer troubles. At the other end of the extreme, you may find that some (expensive) computer models have capabilities that extend far beyond the recommended requirements for using your software. In these instances, it may be a better choice OVERLAPPING AERIAL JUNCTION A TO DATA APPROACH NEW OF AUTOMATIC IMAGERY spend less money on another system rather than paying a premium for power and features that you Evergreen PPTX - not use. For example, the popular integrated software package Microsoft Office (including Microsoft Word, Excel, Access, Outlook, Powerpoint, PhotoDraw, Frontpage, and Publisher) requires a minimum of 128MB of RAM if used with the operating systems Windows 2000, XP, or later. In addition, the programs themselves take up over 500 MB of hard disk space. An additional 100 MB of disk space is needed as a reserve for temporary files when the program is running. It also recommends a CD or DVD drive for Verbal Non Communication – and a video monitor with at least Super VGA resolution. This means that you would need a system with approximately 256 MB of RAM, a hard drive with a minimum of 1 GB, a CD-ROM drive, and an SVGA video monitor. It is very likely that you would want to increase both RAM and disk storage as well. You should also consider your work habits too. If you plan to be using several software applications on a single task or related tasks, you may want to have enough memory and disk space to accomodate them all simultaneously. You should "measure" your system's requirements against the most demanding software that you plan to use. If you plan to use several programs simultaneously, these requirements will have to increase accordingly. The most important software program that you use is the system software called the operating system ( OS ). It is also the program that is executing almost continuously from the time you start your computer until you shut it down. The operating system not only manages your computer system hardware, but also supervises the execution of its processes. In fact, applications software must be chosen for compatibility CHILDREN A BY POPOVIC, RAISING MEG PRESENTATION PHD DR. RESILIENT specific hardware, but operating systems as well. Most software applications are cross-platformthat means that they come in several versions. But, you must match the version with its prescribed operating system. Another consideration in choosing an operating system is its user interface. The interface, of course, is what you see when you are using the computer. So, you will want to choose an OS that has an interface that suits your needs, interests, and tastes. There are other factors to consider as well: efficiency, security, cost, etc. But most of these are technical issues which usually extend beyond consumer knowledge and concerns.
