�Mac OS X �operating system (OS) Operating Systems �file system �handheld operating system �Linux Morrison / Wells CLB: A Comp Guide to IC 3 3 E 6

Understanding the Purpose of an Operating Systems �An operating system (OS) is system software that enables the computer hardware to communicate and operate with the application software. 7 Morrison / Wells CLB: A Comp Guide to IC 3 3 E 7

Drivers Operating Systems �Manufacturers of peripheral devices provide programs called drivers that the operating system uses to communicate with various hardware devices. Morrison / Wells CLB: A Comp Guide to IC 3 3 E 8

Understanding the Purpose of an Operating System (continued) Operating Systems �An operating system also manages resources for applications. �Another way an operating system helps applications is by performing system and file maintenance tasks. 9 Morrison / Wells CLB: A Comp Guide to IC 3 3 E 9

File System Operating Systems �The way an operating system stores files on disk is called a file system. Morrison / Wells CLB: A Comp Guide to IC 3103 E

Understanding the Purpose of an Operating System (continued) Operating Systems �Personal Computer Operating Systems: �An operating system provides an interface between the user or application program and the computer hardware. 11 Morrison / Wells CLB: A Comp Guide to IC 3113 E

Operating Systems Personal Computer Operating Systems 12 �The Windows operating system is designed to work with an Intel processor or clone. Morrison / Wells CLB: A Comp Guide to IC 3123 E

Understanding the Purpose of an Operating System (continued) Operating Systems �Personal Computer Operating Systems (cont): �The Macintosh operating system is called Mac OS X. 13 Morrison / Wells CLB: A Comp Guide to IC 3133 E

Operating Systems Unix 14 �UNIX is a multitasking, portable operating system frequently used by scientists and programmers; Linux is a variant. Morrison / Wells CLB: A Comp Guide to IC 3143 E

Handheld and Embedded Operating Systems: Operating Systems �Handheld operating systems and embedded operating systems, also known as mobile operating systems, are similar in principle to operating systems such as Windows or Linux, but smaller and generally less capable than desktop operating systems. 15 Morrison / Wells CLB: A Comp Guide to IC 3153 E

Common Hand Held Device Operating Systems �Symbian OS �Windows Embedded CE �Windows Mobile Morrison / Wells CLB: A Comp Guide to IC 3163 E

Popular Hand Held Devices Operating Systems �Black. Berry �Embedded Linux �Palm OS Smartphone with Windows Mobile 17 Morrison / Wells CLB: A Comp Guide to IC 3173 E

Operating Systems Sharing Files on Different Operating Systems 18 �In many business, personal, and educational settings, it is necessary to share files across operating system platforms. Morrison / Wells CLB: A Comp Guide to IC 3183 E

Sharing Files on Different Operating Systems �One type of hardware solution is an emulation card that allows the computer to run a program that was designed for a different operating system. Morrison / Wells CLB: A Comp Guide to IC 3193 E

Sharing Files on Different Operating Systems (continued) Operating Systems �Some file types, such as Rich Text Format, are readable on different operating systems. 20 Morrison / Wells CLB: A Comp Guide to IC 3203 E

User Rights Operating Systems �The tasks you are allowed to perform are defined by your user rights, set by the system administrator to protect the computer’s security. �The system administrator is a user who has an administrator account. 21 Morrison / Wells CLB: A Comp Guide to IC 3213 E

Rights Operating Systems �The administrator account provides unrestricted access to make systemwide changes to the computer, such as system modifications, installing software, or changing network settings. �The administrator can grant administrative rights to other users. Morrison / Wells CLB: A Comp Guide to IC 3223 E

Operating Systems Common Operating System Problems 23 �Common issues that affect the operating system include: �Incompatibility �File corruption �Disk crashes Morrison / Wells CLB: A Comp Guide to IC 3233 E

Common Operating System Problems cont. … Operating Systems �Other common types of problems include having trouble completing tasks you normally perform on your computer. Morrison / Wells CLB: A Comp Guide to IC 3243 E

Operating Systems Getting Help 25 �On a Windows 7 computer, Windows Help and Support might provide solutions. Morrison / Wells CLB: A Comp Guide to IC 3253 E

Summary Operating Systems In this lesson, you learned: � An operating system is system software that enables computer hardware to communicate and operate with the application software. Without an operating system, a computer would not function because the operating system manages and coordinates the activities and resources of the computer. 26 Morrison / Wells CLB: A Comp Guide to IC 3263 E

Summary (continued) Operating Systems �Operating systems provide a consistent way for applications to communicate with hardware without duplicating settings or learning details about the hardware. They also perform system and file maintenance tasks. Morrison / Wells CLB: A Comp Guide to IC 3273 E

Summary (continued) Operating Systems �Windows, Mac OS X, and Linux are common operating systems for personal computers. 28 Morrison / Wells CLB: A Comp Guide to IC 3283 E

Summary (continued) Operating Systems �Handheld and embedded operating systems, also known as mobile operating systems, are similar in principle to operating systems such as Windows or Linux. These systems, however, are smaller and generally less capable than desktop operating systems. Morrison / Wells CLB: A Comp Guide to IC 3293 E

Operating Systems Summary (continued) 30 �To share files across operating system platforms, you can use solutions involving hardware, software, and data. For example, saving data or work files in the Rich Text Format means that most other operating systems can read the file. Morrison / Wells CLB: A Comp Guide to IC 3303 E

Summary (continued) Operating Systems �An operating system sets limitations to protect itself and the data on the computer. The operating system grants permission to you to perform some tasks but prevents you from performing others according to your user rights. Morrison / Wells CLB: A Comp Guide to IC 3313 E

Summary (continued) Operating Systems �The system administrator has unrestricted access to make systemwide changes to the computer, including those that affect other users. Without administrative rights, you cannot make changes such as system modifications, installing software, or changing network settings. 32 Morrison / Wells CLB: A Comp Guide to IC 3323 E

Summary (continued) Operating Systems �Typical operating system problems include file incompatibility, file corruption, and disk crashes. Morrison / Wells CLB: A Comp Guide to IC 3333 E
