ITE Essentials Chapters 1-4 Questions And Answers With Verified Solutions

ITE Essentials Chapters 1 -4 amps - the measure of the number of electrons moving through a circuit per second antistatic mat - a mat that is slightly conductive so as to help eliminate static electricity (ESD). It does this by drawing static electricity away from a component and transferring it safely from equipment to a grounding point. antistatic wrist strap - a conductor that connects the wrist of a technician to the device that the technician is working on. When static electricity (ESD) builds up in the body, the connection made by the wrist strap to the device balances the electrical charge by channeling the electricity through the wire that connects the strap. backup - a copy of information such as that stored on the hard drive beep code - POST -generated information that is used in troubleshooting BIOS - firmware that is used during the PC boot process boot order - a BIOS setting for bootable partitions and devices brownout - a situation where voltage drops below 80 percent of the normal voltage over a period of time cable tester - a device that can be used to check the condition of a data cable, including wiring shorts, faults, or wires that are connected to the wrong pins chipset - integrated circuits on the motherboard that control system hardware interaction with the CPU and motherboard clock speed - a function configurable within some BIOS setup programs and that allows for modification of the CPU running speed CMOS - a type of memory where the BIOS settings are saved conversation etiquette - expected professionalism cpu - the brain of the computer Device Manager - a tool that is used to determine if a hardware device is operational diagnostic tools - software that is available to help locate and solve problems disk management - a utility in later Windows operating systems to manage storage devices installed or connected to a computer. The tasks that the utility can perform include initializing disks, creating partitions, and formatting partitions. documentation - the last step as part of a PC repair EMI - stands for electromagnetic interference, a disturbance affecting transmission media that use electrical signals. The disturbance is caused by electromagnetic field variations ESD - stands for electrostatic discharge, a sudden discharge of built -up static electricity between two different surfaces with different charge levels ESD vacuum cleaner - a low airflow device that is used to remove collected dust and materials from inside the case Event Viewer - a tool that is used to see the date and time a problem occurred
