A CPU cache is a hardware cache used by the central processing unit CPU of a computer to reduce the average cost time or energy to access data from the main memory. Chapter 3 Software Information Systems for Business and Beyond. David T. Bourgeois. Learning Objectives. Upon successful completion of this chapter, you will be able to define the term software describe the two primary categories of software describe the role ERP software plays in an organization describe cloud computing and its advantages and disadvantages for use in an organization anddefine the term open source and identify its primary characteristics. Introduction. The second component of an information system is software. Simply put Software is the set of instructions that tell the hardware what to do. Technical Reference Guide HP Compaq dc7900 Series Business Desktop Computers Document Part Number 506665001 September 2008 This document provides information on the. In computer architecture, 512bit integers, memory addresses, or other data units are those that are 512 bits wide. Also, 512bit CPU and ALU architectures are those. Computing acronyms are confusing. What is a CPU anyway And do I need a quad or dualcore processor How about AMD, or Intel Were here to help explain the differenceSoftware is created through the process of programming we will cover the creation of software in more detail in chapter 1. Without software, the hardware would not be functional. Links/03fig01.jpg' alt='Cpu Components And Functions Pdf To Word' title='Cpu Components And Functions Pdf To Word' />Types of Software. Software can be broadly divided into two categories operating systems and application software. Operating systems manage the hardware and create the interface between the hardware and the user. Application software is the category of programs that do something useful for the user. Operating Systems. The operating system provides several essential functions, including managing the hardware resources of the computer providing the user interface components providing a platform for software developers to write applications.

For personal computers, the most popular operating systems are Microsofts Windows, Apples OS X, and different versions of Linux. Smartphones and tablets run operating systems as well, such as Apples i. OS, Googles Android, Microsofts Windows Mobile, and Blackberry. The Central Processing Unit CPU is considered the brains of a computer. This internal component is inserted directly into a socket on the motherboard.

Early personal computer operating systems were simple by todays standards they did not provide multitasking and required the user to type commands to initiate an action. The amount of memory that early operating systems could handle was limited as well, making large programs impractical to run. The most popular of the early operating systems was IBMs Disk Operating System, or DOS, which was actually developed for them by Microsoft. In 1. 98. 4, Apple introduced the Macintosh computer, featuring an operating system with a graphical user interface. Though not the first graphical operating system, it was the first one to find commercial success. In 1. 98. 5, Microsoft released the first version of Windows. This version of Windows was not an operating system, but instead was an application that ran on top of the DOS operating system, providing a graphical environment. It was quite limited and had little commercial success. It was not until the 1. Windows 3. 0 that Microsoft found success with a graphical user interface. Because of the hold of IBM and IBM compatible personal computers on business, it was not until Windows 3. Since 1. 99. 0, both Apple and Microsoft have released many new versions of their operating systems, with each release adding the ability to process more data at once and access more memory. Features such as multitasking, virtual memory, and voice input have become standard features of both operating systems. Linux logo Copyright Larry EwingA third personal computer operating system family that is gaining in popularity is Linux pronounced linn ex. Linux is a version of the Unix operating system that runs on the personal computer. Unix is an operating system used primarily by scientists and engineers on larger minicomputers. These are very expensive computers, and software developer Linus Torvalds wanted to find a way to make Unix run on less expensive personal computers. Linux was the result. Linux has many variations and now powers a large percentage of web servers in the world. It is also an example of open source software, a topic we will cover later in this chapter. Sidebar Mac vs. Windows. Are you a Mac Are you a PCEver since its introduction in 1. Apple Macintosh have been quite biased about their preference for the Macintosh operating system now called OS X over Microsofts. When Microsoft introduced Windows, Apple sued Microsoft, claiming that they copied the look and feel of the Macintosh operating system. In the end, Microsoft successfully defended themselves. Over the past few years, Microsoft and Apple have traded barbs with each other, each claiming to have a better operating system and software. While Microsoft has always had the larger market share see sidebar, Apple has been the favorite of artists, musicians, and the technology elite. Apple also provides a lot of computers to elementary schools, thus gaining a following among the younger generation. Sidebar Why Is Microsoft Software So Dominant in the Business World If youve worked in the world of business, you may have noticed that almost all of the computers run a version of Microsofts Windows operating system. Why is this On almost all college campuses, you see a preponderance of Apple Macintosh laptops. In elementary schools, Apple reigns as well. Why has this not extended into the business worldAs we learned in chapter 1, almost all businesses used IBM mainframe computers back in the 1. These same businesses shied away from personal computers until IBM released the PC in 1. When executives had to make a decision about purchasing personal computers for their employees, they would choose the safe route and purchase IBM. The saying then was No one ever got fired for buying IBM. So over the next decade, companies bought IBM personal computers or those compatible with them, which ran an operating system called DOS. DOS was created by Microsoft, so when Microsoft released Windows as the next iteration of DOS, companies took the safe route and started purchasing Windows. Microsoft soon found itself with the dominant personal computer operating system for businesses. As the networked personal computer began to replace the mainframe computer as the primary way of computing inside businesses, it became essential for Microsoft to give businesses the ability to administer and secure their networks. Microsoft developed business level server products to go along with their personal computer products, thereby providing a complete business solution. And so now, the saying goes No one ever got fired for buying Microsoft. Application Software. The second major category of software is application software. Application software is, essentially, software that allows the user to accomplish some goal or purpose. For example, if you have to write a paper, you might use the application software program Microsoft Word. If you want to listen to music, you might use i. Tunes. To surf the web, you might use Internet Explorer or Firefox. Even a computer game could be considered application software. The Killer App. Visi. Calc running on an Apple II. Public DomainWhen a new type of digital device is invented, there are generally a small group of technology enthusiasts who will purchase it just for the joy of figuring out how it works. However, for most of us, until a device can actually do something useful we are not going to spend our hard earned money on it. A killer application is one that becomes so essential that large numbers of people will buy a device just to run that application. For the personal computer, the killer application was the spreadsheet. In 1. 97. 9, Visi. Calc, the first personal computer spreadsheet package, was introduced. It was an immediate hit and drove sales of the Apple II. It also solidified the value of the personal computer beyond the relatively small circle of technology geeks. When the IBM PC was released, another spreadsheet program, Lotus 1 2 3, was the killer app for business users. Productivity Software. Along with the spreadsheet, several other software applications have become standard tools for the workplace. These applications, called productivity software, allow office employees to complete their daily work. Many times, these applications come packaged together, such as in Microsofts Office suite.
