  1. 1. A+ Guide to Managing and Maintaining your PC, 6e (Comprehensive)CHAPTER 1REVIEWING 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 humanlanguage. All instructions between hardware and software in a computer are reduced to a simpleyes 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 themonitor 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 thedevice, 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 isnot on the motherboard to communicate with the CPU. 7. Which component on the motherboard is used primarily for processing?
  2. 2. The CPU (central processing unit), also called the processor 8. Name three CPU manufacturers.Possible answers: Intel, AMD, Cyrix, IBM 9.

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 adevice. 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, mouseport, 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 andthe 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. 3. Volatile memory is temporary and needs a constant electrical charge to hold data. Nonvolatilememory 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. 4. 23. ROM BIOS or firmware chips that can be upgraded without replacing the chips are called ________.Flash ROM 24.

  5. 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 themotherboard or computer case.THINKING CRITICALLY1. 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. Ifthe power is lost, all data in primary storage is lost. In order to secure the data, it must be copiedfrom primary storage to secondary storage, such as a hard drive or floppy disk, which isnonvolatile 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 bits4. 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 fourEIDE 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. 6. Get creative.Possible answer: A water hydrant is either on or off. It is difficult to measure the amount of watercoming 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 beavailable. This information includes the type of hard drive and floppy drive installed and the bootsequence.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 speedbecause the term speed implies there is a continuous motion or flow of data, whereas frequencysuggests a digital or binary flow of data. Frequency is more accurate because computertechnology is built using the binary on/off system.Chapter 2REVIEWING THE BASICS 1.

Make sure it is seated in the socket at the same height as other modules.• Remove the newly installed memory and check whether the error message disappears. Try the memory in different sockets. Try installing the new memory without the old installed. If the new memory works without the old, then the problem is that the modules are not compatible.• Clean the module edge connectors with a soft cloth or contact cleaner. Blow or vacuum dust from the memory sockets.• Try flashing your BIOS. Perhaps BIOS is having problems with the new memory, which can be solved by a BIOS upgrade. 13. What might be a symptom in Windows of unreliable memory on a motherboard?A general protection fault or other memory error or the system freezes or hangs. 14.
