1 A+ Guide to Managing and Maintaining your PC, 6e (Comprehensive) CHAPTER 1 REVIEWING THE BASICS 1. Why is all data stored in a computer in binary form? Binary is the format that the computer understands, not a programming language or a human language. All instructions between hardware and software in a computer are reduced to a simple yes or no, a state of on or off. 2. What are the four primary functions of hardware? Input, processing, output, and storage 3. What are the two main input devices and two main output devices? The two main input devices are the keyboard and the mouse. The two main output devices are the monitor and the printer. 4. What three things do electronic hardware devices need in order to function? A method for the CPU to communicate with the device, software to instruct and control the device, and electricity to power the device 5. How many bits are in a byte? Eight 6. What is the purpose of an expansion slot on a motherboard? An expansion slot on a motherboard is used for an expansion card, which enables a device that is not on the motherboard to communicate with the CPU. 7. Which component on the motherboard is used primarily for processing?

2 The CPU (central processing unit), also called the processor 8. Name three CPU manufacturers. Possible answers: Intel, AMD, Cyrix, IBM 9. What technology is most often used today to manufacture microchips? CMOS (complementary metal-oxide semiconductor) 10. What are two other names for the system bus? Possible answers: memory bus, host bus, front side bus, external bus 11. What are two other names for the motherboard? Main board, system board 12. What are the two basic types of cables found inside a computer case and what are their basic functions? A data cable used for passing data between devices and a power cable used to supply power to a device. 13. List three types of ports that are often found coming directly off the motherboard to be used by external devices. Possible answers: serial port, parallel port, USB port, network port, FireWire or 1394 port, mouse port, keyboard port, S/PDIF port, sound port, wireless LAN antenna port 14. What is the purpose of the S/PDIF port? The S/PDIF port connects to an external home theater audio system, providing digital output and the best signal quality. 15. List three kinds of memory modules. SIMMs (single inline memory modules), DIMMs (dual inline memory modules), RIMMs 16. What is the difference between volatile and nonvolatile memory?

3 Volatile memory is temporary and needs a constant electrical charge to hold data. Nonvolatile memory is permanent and holds memory even when electricity is turned off. 17. Of the two types of storage in a system, which type is generally faster and holds data and instructions while the data is being processed? Which type of storage is generally slower, but more permanent? Primary storage, secondary storage 18. What technology standard provides for up to four devices on a system, including the hard drive as one of those devices? What are two common industry names loosely used to describe this standard? ATA (AT attachment), also called EIDE (enhanced integrated drive electronics) or IDE 19. What is the size of the data path on most system buses today? 64 bits 20. What is the measurement of frequency of a system bus and CPU? Which is faster, the system bus or the CPU? Frequency is generally measured in Hz, MHz, or GHz. The CPU is faster than the system bus. 21. Name four types of buses that are likely to be on a motherboard today. Possible answers: PCI (Peripheral Component Interconnect), AGP (Accelerated Graphics Port), ISA (Industry Standard Architecture), system bus, PCI Express 22. A power supply receives 120 volts of power from a wall outlet and converts it to 3.3, 5, and 12 volts of power. AC, DC

4 23. ROM BIOS or firmware chips that can be upgraded without replacing the chips are called. Flash ROM 24. CMOS setup allows a technician to change configuration settings on a motherboard stored in. CMOS RAM 25. Name three examples of secondary storage devices. Some possible answers: CD drive, hard drive, floppy drive, DVD drive, Zip drive 26. A hertz is cycle per second; a megahertz is cycles per second, and a gigahertz is cycles per second. One, one million, and one billion 27. An AGP slot is normally used for a(n) expansion card. Video 28. How many sizes of PCI Express slots are currently manufactured for personal computers? Four 29. Name the three purposes the motherboard ROM BIOS serves. The BIOS is used to manage simple devices (system BIOS), to start the computer (startup BIOS), and to change settings on the motherboard (CMOS setup).

5 30. From where does CMOS RAM receive its power? CMOS RAM is powered by a trickle of electricity from a small battery located on the motherboard or computer case. THINKING CRITICALLY 1. When selecting secondary storage devices for a new desktop PC, which is more important, a CD-ROM drive or a floppy drive? Why? A CD-ROM drive is more important, because most software today is distributed on CD. 2. Based on what you have learned in this chapter, when working on a Word document, why is it important to save your work often? Explain your answer using the two terms, primary storage and secondary storage. It is important because data is temporarily stored in RAM or primary storage, which is volatile. If the power is lost, all data in primary storage is lost. In order to secure the data, it must be copied from primary storage to secondary storage, such as a hard drive or floppy disk, which is nonvolatile or permanent storage. 3. Most buses are 16, 32, 64, or 128 bits wide. Why do you think these bus widths are multiples of eight? Because everything in a computer is stored and processed in binary, and 1 byte equals 8 bits 4. Why would it be difficult to install four hard drives, one CD-ROM drive, and one DVD drive in a single low-end system? These types of drives are normally EIDE devices, and most low-end systems can only hold four EIDE devices. Also, most computer cases do not have enough bays to hold this many drives. 5. In this chapter, a light bulb is used to demonstrate the binary concept used for computer storage and communication. Give another example in everyday life to explain this binary concept.

6 Get creative. Possible answer: A water hydrant is either on or off. It is difficult to measure the amount of water coming out of the hydrant, but not difficult to decide if the water is off or on. 6. If the CMOS battery inside your computer system died, when you first turn on your system, will you expect the system to boot up normally to the operating system level? What information do you think the system would not have available for a successful boot? No, the system will not boot normally because the configuration information would not be available. This information includes the type of hard drive and floppy drive installed and the boot sequence. 7. Why is it more accurate to describe the CPU and motherboard bus using the term frequency rather than speed? Explain your answer. It is more accurate to describe the CPU and motherboard with the term frequency than speed because the term speed implies there is a continuous motion or flow of data, whereas frequency suggests a digital or binary flow of data. Frequency is more accurate because computer technology is built using the binary on/off system. Chapter 2 REVIEWING THE BASICS 1. List four major functions of an OS. It manages hardware; runs applications; provides an interface for users; and stores, retrieves, and manipulates files. 2. Which operating system is only used on Apple Macintosh computers? Mac OS

The essential intermediary role played by an operating system is captured in Figure Indicate that operating systems can be better appreciated and understood when they are studied in historical context. Teaching Tip Emphasize that the operating system has been instrumental in transforming the computer into a user and application friendly device. Using Figure 2-1, explain that without the operating system, the responsibility for accessing and coordinating system resources would revert to the user and/or application. DOS (Disk Operating System) 1. Introduce DOS (disk operating system) as a command-line driven set of programs. Note that DOS was the first OS used in IBM computers and IBM compatibles. 2. Justify the need to study DOS based on its use in legacy systems and support of various system utilities.

12 A+ Guide to Managing and Maintaining your PC, 6e Using Figure 2-3, demonstrate the hidden role played by DOS in Windows 3.x systems. Describe how Windows 9x/Mx and Windows 2000/XP relate to DOS. Teaching Tip Inform students that DOS is actually a generic name that describes a family of operating systems, such as PC-DOS and MS-DOS. Windows 9X/ME 1. Indicate that Windows 9x/Me refers to Refers to Windows 95, Windows 98, and Windows Me. Emphasize that each of these systems runs a user-friendly graphical interface on a DOS core. 2. Define the terms, backward-compatible and legacy systems. Using Figure 2-5, show how Windows 9x/Me forms a bridge between old and new technologies. 3. Using Table 2-1, illustrate the different requirements for the systems that make up the Windows 9x/Me series. Explain how minimum requirements for each system can vary between upgrades and new installations. Add that minimum requirements can also vary between installation and run-time operation. Windows NT 1. Indicate that there are two versions of Windows NT (New Technology): Windows NT Workstation and Windows NT Server. 2. Windows NT replaced the DOS core with a new core operating system, but introduced many new problems. These problems were only solved in later versions of Windows. Advise students to avoid installing Windows NT. Windows Indicate that Windows 2000 is an upgrade of Windows NT and comes in versions for desktops and high-end servers. Highlight the improvements over Windows NT: a more stable environment, support for Plug and Play, Device Manager, Recovery Console, Active Directory, better network support, and features specifically targeting notebook computers. The desktop can be viewed in Figure Advise students that hardware and software must qualify for Windows 2000 Professional desktop. A web site that lists approved components is provided in the text. The text also specifies system requirements. 3. As with Windows NT, new versions of Windows 2000 should not be installed. For the most part, Microsoft no longer supports the operating system.

Indicate that Windows Server 2003 refers to a suite of operating systems, which are listed in the text. As they are not intended for use in a PC, they are not covered. 1. The term UNIX comprises a class of operating systems used to control networks and applications on the Internet. Versions of UNIX are referred to as flavors or distributions.

14 A+ Guide to Managing and Maintaining your PC, 6e 2-5 Linux OS/2 1. Introduce Linux as a variation on UNIX developed by Linus Torvald. Both the Linux OS kernel and kernel's source code are freely distributed. Students can experiment with Linux without creating a disk partition or volume, and without major cost. Review the three installation tips described in the text. 2. Indicate that the Linux OS is used in both server platforms and desktop platforms, though it is more prevalent in the former. It is a robust operating system that is a good training tool for UNIX. 3. GUI shells written for UNIX and Linux are collectively referred to as X Windows (Figure 2-9). Mac OS 1. Developed jointly by IBM and Microsoft, the OS/2 is generally limited to certain networks. Windows NT uses some of the core components of OS/2 1. The Mac OS was introduced in 1984 for exclusive use in Macintosh computers. The most recent version, Mac OS X, can now run on other Intel-based computers. It has not yet been licensed for use on non-macintosh computers. 2. There are several important markets for the Mac OS (and Mac): educational institutions, graphics, and desktop publishing. 3.

Answer: Finder

15 A+ Guide to Managing and Maintaining your PC, 6e 2-6 What an Operating System Does 1. Describe the four functions common to all operating systems: Providing a user interface Managing files Managing applications Managing hardware 2. Along with four common functions, all OSs share similar core components. These components will be reviewed in the following sections. Operating System Components 1. Indicate that the shell and the kernel are two components common to all operating systems. Using Figure 2-11, explain how the shell services both users and applications. Present the author's analogy of the division of labor in a restaurant-, the host and waiters are like shell routines, while the chefs and kitchen staff members are like the kernel. Highlight specific services provided by the shell, such as handling an application's command to print a document. 2. Describe the role of the registry database and initialization files in Windows. An OS Provides a User Interface 1. After a PC is turned on, the OS is loaded. In the process of taking control over the PC, the OS presents a desktop to the user. Events generated by the user drive the operating system to perform additional tasks. These events include the click of a menu item, the double-click of an icon, or the entry of a text command. 2. Indicate that there are two ways to pass a text command to the Windows XP OS: using the Run option on the Start menu or by using the command console. The command console can be opened by entering Cmd in the Run dialog box or by following the path Start All Programs Accessories and then clicking "Command Prompt". The sample command used in the text is DEFRAG C:. 3. Using Figure 2-13, a screen print of Windows Explorer, explain that most Windows interface tools combine menus and icons. 4. Define the terms, graphical user interface (GUI) and desktop. Teaching Tip There are two common reasons why a command won't work in Windows XP: the command is spelled incorrectly or the path to the command utility is not specified. If students experience the second problem using the command console, they meet to set their path variable as follows: path = C:\Windows\System32.

16 A+ Guide to Managing and Maintaining your PC, 6e 2-7 An OS Manages Files and Folders 1. Indicate that the OS uses a file system to organize files and folders on a hard drive or floppy disk. Two file systems used by Windows are: File systems used by Windows are File Allocation Table (FAT) and New Technology File System (NTFS). NTFS is replacing FAT. 2. Using Figure 2-14, explain how a hard drive or floppy disk is organized to support files and folders. In your explanation, include the terms, track, sector and cluster. Emphasize that the cluster is the smallest unit on disk for storing a file. Clusters are tracked by file systems, such as FAT and NTFS. Files and Directories 1. As shown in Figure 2-15, the file system hierarchy consists of directories, subdirectories (child directories), and files. Directories are called folders in Windows. Directories can contain a number of subdirectories and files. A directory table lists the various subdirectories and files. Each logical drive contains a root directory. For example, C:\ is the root directory for the C drive. 2. The path to a file consists of a drive, directory, 0 to 1 or more subdirectories, a filename, and a file extension. Figure 2-16 breaks down the parts of the sample path, C:\wp\data\myfile.txt. Partitions and Logical Drives on a Hard Drive 1. Describe the uses of primary and extended partitions. Using Figure 2-17, illustrate the hierarchical relationship among partitions, logical drives (volumes), directories, subdirectories, files, and data. 2. Note that partitions can be created when a drive is first installed, when an OS is first installed, or after an existing partition becomes corrupted. 3. Indicate that the Disk Management tool (Figure 2-18) can be used to create partitions, view partitions, and format logical drives. Show students how to open the Disk Management utility. An OS Manages Applications 1. Indicate that the OS is used to install and run all software on a PC. Applications depend on the OS to provide various services, such as memory management. Advise students that applications are typically tailored to a specific OS. The application may not function properly on a foreign OS; it also may not function properly on a newer version of the native OS.

17 A+ Guide to Managing and Maintaining your PC, 6e 2-8 Launching Application Software Using the Windows Desktop 1. Advise students that an application has to be started before it can be used. Various terms refer to starting an application: running, loading, launching, or executing an application. 2. There are four ways to start up an application in Windows. Referring back to the text, show students how to use the following: a shortcut icon, the Start menu, the Run command, Windows Explorer or My Computer. Real (16-bit), Protected (32-bit), and Long (64-bit) Operating Modes 1. The bit designation in each mode refers to the number of bits that can be simultaneously processed. DOS uses the 16-bit mode. Windows 9x/Me and Windows NT/2000/XP all use 32-bit Mode. Windows XP Professional x64 Edition uses 64-bit mode. Each OS listed after DOS is backwardly compatible with earlier modes. Modern processors are built to run in either 32-bit or 64-bit mode and are backwardly compatible with 16-bit mode. 2. Modern operating systems no longer use the real mode, since this mode directly exposes the application to hardware resources. Instead, they run in protected or long mode, which control how an application accesses hardware. 3. Using Figure 2-22, describe preemptive multitasking. Distinguish multitasking from multiprocessing. The former shares multiple applications with a single CPU, while the latter distributes work loads across multiple CPUs. 16-bit, 32-bit, and 64-bit Software bit software was written for Windows 3.x. 32-bit programs are written for Windows NT/2000/XP and Windows 9x/Me. 64-bit programs are written for Windows XP Professional x64 Edition. Most software today is 32-bit or 64-bit. An OS Manages Hardware 1. Indicate that the operating system interacts with hardware using device drivers or BIOS. 2. After introducing device drivers, highlight the three distinct layers of software thus far presented: device drivers or BIOS, the operating system, and application software. Figure 2-23 illustrates the relationship among the three layers. How an OS Uses Device Drivers to Manage Devices 1. Referring once again to Figure 2-23, describe the role of device drivers. Emphasize that device drivers are typically tailored to a particular operating system. The operating system is used to both install and manage device drivers. 2. Device driver software is installed either when the system is initially configured or a new hardware device is added. In the latter scenario, the driver software is usually stored on a CD or floppy disk and bundled with the hardware device. Figure 2-24

18 A+ Guide to Managing and Maintaining your PC, 6e 2-9 shows a package including a video card, a CD containing device driver software, and a user manual. 3. Indicate the three kinds of device drivers: 16-bit real-mode drivers, 32-bit protectedmode drivers, and 64-bit long-mode drivers. Associate each kind of driver with their supporting Windows operating systems. 4. Review the special procedures for installing and operating device drivers in Windows 2000/XP and Windows 9x/Me. Teaching Tip Device drivers were originally extensions to applications, such as the DOSbased Lotus The inability of application software to keep up with new devices, such as new printers, caused the driver software architecture to change. In the new scheme, the driver has become an extension of the OS. How an OS Uses System BIOS to Manage Devices 1. Using the scenario of system startup, explain how system BIOS (basic input/output system) is used to directly interact with hardware devices, such as floppy drives or keyboards. Indicate that the OS may use BIOS as an alternative to drivers for accessing a device. There is a significant disadvantage to using BIOS for device access: it operates at slower speeds than device drivers. 2. Remind students that system BIOS is hard-coded into ROM BIOS chips. Through CMOS setup, you can control how system BIOS recognizes and uses devices. How an OS Manages Memory 1. List the main memory functions performed by the OS: Assigning addresses to each location in memory Tracking the amount of available memory Moving data in and out of memory 2. Using Figure 2-26, illustrate how the memory addresses enable the three layer software layers to refer to a shared piece of data. 3. Using Figure 2-27, distinguish between 16-bit applications running in real mode from 32-bit programs running in protected mode. Emphasize how protected mode enables the OS to mediate application access to RAM. The OS can insulate the address space of an application running in protected mode. By combining address space protection with virtual memory, the OS can safely support multitasking.

19 A+ Guide to Managing and Maintaining your PC, 6e 2-10 Quick Quiz 2 1. A(n) is the portion of the OS that relates to the user and to applications. Answer: shell 2. When each logical drive is formatted, a single directory table is placed on the drive called the directory. Answer: root 3. Device are small programs stored on the hard drive that tell the computer how to communicate with a specific hardware device such as a printer, network card, or modem. Answer: drivers 4. True or False. Windows NT/2000/XP forces all programs to run in protected mode, and it controls how that software accesses memory. Answer: True OS Tools to Examine a System 1. Inform students that there are many diagnostic and configuration tools built into Windows. They will be covered in the following sections. The Windows Desktop 1. Introduce the Windows desktop as the primary tool provided by the Windows shell. Using Figure 2-28, highlight the important components of the Start menu.

Explain the functions of the Display Properties window (Figures 2-30 to 2-31), the taskbar and system tray (Figures 2-32 to 2-33), and shortcuts (Figures 2-34 to 2-36). Teaching Tip The Properties dialog box of a shortcut created by the user includes a number of useful features. For example, the Shortcut tab shows the location of the target file, and also enables the user to quickly navigate to the target. My Computer and Windows Explorer 1. Explain that Windows Explorer is a graphical tool used to navigate directories and manipulate folders and files. My Computer is now a component of Windows Explorer that specializes in drive and disk information.

Show students how to enable, disable, and uninstall devices. Demonstrate how to update, roll back, and uninstall device drivers. System Information 1. Introduce System Information as a comprehensive information resource (see Figure 2-50). Demonstrate how to open the utility by entering Msinfo32.exe in the Run dialog box. Identify the most important information gathered from the tool: the BIOS version you are using, the directory where the OS is installed, how system resources are used, and information about drivers and their status. Windows Help and the Microsoft Web Site 1. Show students how to open Windows Help. Indicate that Windows Help is a useful guide to the system and troubleshooting resource. Demonstrate how to diagnose a problem with an Internet connection (Figure 2-51).

21 A+ Guide to Managing and Maintaining your PC, 6e Indicate that the primary Internet resource for help is the Microsoft Web site, Show students how to search for information at this site. Advise students that other sites on the Internet may also provide valuable assistance. Before relying on information provided by an alternative site, the site's reputation should be verified. Keystroke Shortcuts in the OS 1. Using Table 2-3, review the shortcuts that can be used in Windows. Demonstrate task performed with various shortcuts, such as the function keys and text edit operation key combinations. Emphasize that knowledge of keyboard shortcuts is critical when the mouse is not operational. Quick Quiz 3 1. True or False. The Windows desktop is the primary tool provided by the Windows shell. Answer: True 2. A(n) is a program that runs in the background to support or serve Windows or an application. Answer: service 3. A(n) on the desktop is an icon that points to a program you can execute, or to a file or folder. Answer: shortcut 4. Manager is your primary Windows tool when solving problems with hardware. Answer: Device Class Discussion Topics 1. Refer to Figure 2-1. Would it be possible to shift the responsibility of hardware resource management from the operating system to an application, such as Microsoft Word? If possible, would such a task reassignment be desirable or feasible? 2. Compare and contrast the two tools used to interact with an operating system: a graphical user interface (GUI) and a command console. To what extent has the GUI tool replaced the command console?
