Geoffrey’s A+ Certification For Dummies (Book 2, Chapter 1) Flashcards
How many devices are supported in a USB chain? A) 10 B) 27 C) 127 D) 255
C) A computer can support up to 127 USB devices in a USB chain.
How many pins are in the end of a parallel cable connector that connects to the computer? A) 36 B) 40 C) 25 D) 33
C) A parallel cable has a different style of connector at each end of the cable. The end that connects to the computer has 25 pins, and the end that connects to the printer has 36 pins.
How many pins does a standard floppy drive controller have? A) 34 pins B) 40 pins C) 50 pins D) 75 pins
A) A floppy drive connector has 34 pins, and an IDE connector has 40 pins, and internal SCSI devices have 50 pins.
How many pins does a standard IDE controller have? A) 33 pins B) 40 pins C) 50 pins D) 20 pins
B) An IDE controller has 40 pins to allow a 40-wire ribbon cable to connect a hard disk or CD-ROM to the motherboard. A floppy controller uses 33 pins, and 50 pins are used by internal SCSI devices.
What are the labels given to the power connectors that supply power to the motherboard? A) P1 and P2 B) P22 and P2 C) PT1 and PT2 D) PS1 and PS2
A) P1 and P2 are the typical labels given to a motherboard’s power connectors.
What is the bus architecture used in laptop computers? A) PCI B) PCMCIA C) EISA D) ISA
B) The bus architecture used in laptop computers is called PCMCIA (Personal Computer Memory Card Industry Association). The other three choices are bus architectures available to desktop computers.
What type of cache memory will you find on a motherboard? A) L1 B) L2 C) SDRAM D) SRAM
B) Level 2 (L2) cache is the type of cache memory that is found on motherboards, whereas Level 1 (L1) cache is found in the processor. Choices C and D are not types of cache memory.
What was the original motherboard speed of the ATX board? A) 33 MHz B) 60 MHz C) 66 MHz D) 100 MHz
D) The ATX board had an original motherboard speed of 100 MHz. Older boards, such as the Baby AT, had motherboard speeds of 60 and 66 MHz.
When connecting a floppy drive to the system, which end of the ribbon cable connects to the floppy drive? A) The end with a red stripe B) The end with a twist C) The end with a blue stripe D) The end without a twist
B) The floppy ribbon cable has one end that is twisted; that twisted end must be connected to the floppy drive.
Which bus architecture might be found in older IBM servers? A) ISA B) MCA C) VESA D) EISA
B) In the past, you were likely to see MCA in older IBM servers because IBM developed the MCA bus architecture.
Which bus architecture runs at 8 MHz and supports 16-bit ISA cards? A) MCA B) AGP C) PCI D) EISA
A) MCA
B) AGP
C) PCI
D) EISA
What is the bus architecture used in laptop computers? A) PCI B) PCMCIA C) EISA D) ISA
B) The bus architecture used in laptop computers is called PCMCIA (Personal Computer Memory Card Industry Association). The other three choices are bus architectures available to desktop computers.
Which of the following best describes AGP?
A) AGP slots have a direct path to the processor to help increase performance of AGP devices.
B) AGP cards run at 33 MHz.
C) AGP runs at 66 MHz and gets access to the processor through the PCI bus.
D) AGP stands for Advanced Graphics Port and is used to install additional video memory.
A) The AGP slot runs at 66 MHz and has a direct path between the slot and the processor so that information will not have to travel through one of the slower buses. AGP stands for Advanced Graphics Port and is used to install a video card, not video memory.
Which PCMCIA card type is used for modems? A) Type I B) Type II C) Type III D) Type IV
B) Type II cards are used for network cards and modems. Type I cards are used for memory upgrades, and Type III cards are used for removable drives.
Which port is typically used for a modem? A) USB B) LPT1 C) COM1 D) LPT2
C) COM1 is a serial port that is typically used for modems or serial mice. LPT ports are parallel ports that are generally used to connect printers.
