Describe symptoms that may indicate that two devices are attempting to use the same IRQ.
(41) 
VerifiedAny of the following symptoms could indicate that two devices are attempting to use the same IRQ:
·The computer might lock up or "hang" either upon starting or when the operating system is loading.
·The computer might run much more slowly than usual.
·Although the computer's NIC might work properly,other devices - such as USB or parallel ports - may stop working.
·Video or sound card problems might occur.For example,after the operating system loads,you may see an error message indicating that the video settings are incorrect,or your sound card may stop working.
·The computer might fail to connect to the network (as evidenced by an error message after you attempt to log on to a server,for example).
·The computer might experience intermittent data errors during transmission.
When selecting a NIC to install,explain what an administrator should do if a motherboard supports more than one kind of expansion slot.
(44) VerifiedIf a motherboard supports more than one kind of expansion slot,refer to the NIC and PC manufacturers' guidelines (either in print or on the Web)for information on the preferred type of NIC.If possible,you should choose a NIC that matches the most modern bus on the motherboard.For example,if a PC supports both ISA and PCI,attempt to use a PCI NIC.Although you may be able to use the older bus and NIC types without any adverse effects,some NICs will not work in an older bus if a faster,newer bus is available on the motherboard.
CompactFlash NICs are most frequently used to connect devices too small to handle PCMCIA slots.
(38) VerifiedTrue

(36) ____ is a type of microchip that requires very little energy to operate.
(40) Switches that operate anywhere between Layer 4 and Layer 7 are also known as ____ switches.
(33) The ____________________ indicates,in hexadecimal notation,the area of memory that the NIC and CPU use for exchanging,or buffering,data.
(35) A computer's ____________________ is the circuit,or signaling pathway,used by the motherboard to transmit data to the computer's components,including its memory,processor,hard disk,and NIC.
