اسلاید 2: Chapter 11: ObjectivesGive an overview of field, remote, and bench technician jobs. Explain safe lab procedures and tool use. Describe situations requiring replacement of computer components. Upgrade and configure personal computer components and peripherals. Identify and apply common preventive maintenance techniques for personal computer components. Troubleshoot computer components and peripherals.

اسلاید 3: Chapter 11: Critical ConceptsWhat is this chapter about and why is it important?Replacing computer parts is commonplace in a technician’s job. Learning how to safely replace parts and find suitable replacement parts is essential. Various computers may have different locations for hard drives or where specific adapters are installed, but the concepts are the same. Practicing on outdated parts is not a problem because the key to success is practice. With practice comes a sense of capability and confidence.

اسلاید 18: Chapter 11: Classroom Management Have the students research a replacement power supply of equal wattage and with the appropriate power connectors.Provide copies of motherboard documentation to the students. Have the students research the type of memory and the maximum amount of memory that can be supported by that motherboard. Most of the time spent on memory upgrade is in the planning, selection, and purchasing of memory. Have the students determine what to purchase if a computer with 256K of memory needs to be upgraded to 2GB. Provide extra hard drives to the students. Have the students install a second hard drive and then partition both drives with different sizes and types of partitions. Demonstrate flashing the BIOS of lab computers, even if the BIOS is up to date, so the students see the process.Use an older motherboard to demonstrate the removal and installation of a CPU.

اسلاید 19: Chapter 11: Teaching AnalogiesUpgrading a computer is like replacing a part on your car. You must obtain a part that is compatible with your system. Compatibility is very important for the memory, CPU, and power supply of a computer.

اسلاید 20: What are the different types of certification?How do you prepare and register for a certification exam? How can you determine if a processor is compatible with a motherboard? How can you determine if a particular type and amount of memory is compatible with a motherboard?What are some reasons to implement different levels of RAID?Chapter 11: Suggested Class Discussions

اسلاید 21: Chapter 11: Best PracticesObtain old hard drives from technicians or computer stores. Even if they are low capacity, they can be used to demonstrate the concepts of partitioning and formatting. Install two video adapters and configure dual monitors. This is a common implementation in many work environments.
