Chapter 4 Motherboards and I/O Buses

Question 1

Information and data travels along this line or road which is narrow or wide.

Answer 1

Data bus line

Question 2

Generates voltage to the components connected in the motherboard or the power source

Answer 2

Power bus line

Question 3

Regulates the data trafficking of information flow or the stoplights in a city

Answer 3

Control bus line

Question 4

This is used to pick up information from the correct memory location among the gigabytes of RAM in computer systems and deliver new programs and changes back to the correct memory locations or the mailmen

Answer 4

Address bus line

Question 5

System Bus

Answer 5

consists of lines for data to travel from one component to the next.

Question 6

Motherboard

Answer 6

everything that makes a computer, includes CPU to storage devices, from the CPU to storage devices, from RAM to printer ports, the motherboard provides the connections that help them work together.

Question 7

Chipset

Answer 7

North and South Bridges of the motherboard

Question 8

MCH

Answer 8

Memory Controller Hub which provides a connection between the CPU (central processor unit), the RAM and some PCI Express devices and handles the communication between these components.

Question 9

RAM

Answer 9

Random Access Memory which is the virtual memory data bank stored during the clients session only.

Question 10

ICH

Answer 10

I/O Controller Hub provides the central connection point between all the secondary systems such as USB, FireWire, and hard drives. It connects the MCH through the DMI (Direct Media Interface).

Question 11

ATX

Answer 11

A rear port cluster for I/O ports
Expansion slots that run parallel to the short side of motherboard
Left side case opening

Question 12

BTX

Answer 12

Balanced technology extended. Heat-producing components such as the processor, memory, chipset and voltage regulator are relocated
The processor socket is mounted at a 45-degree angle to the front of the motherboard
A thermal module with a horizontal fan fits over the processor for cooling
The port cluster is moved to the rear left corner
BTX cases include multiple rear and side air vents for better cooling
BTX tower cases use a right-opening design

Question 13

NLX

Answer 13

New low profile extended motherboards which feature a Riser card and daughter-boards which include one or more PCI expansion slots.

Question 14

Daughterboard

Answer 14

circuit board that plugs into another board to provide extra functionality.

Question 15

The most recent motherboards include which integrated ports>?

Answer 15

Serial Ports
LPT ports
PS/2 Ports
USB 2.0 hi-speed USB
10/100 or 10/100/1000 Ethernet cable
Audio 1/8 inch mini jack

Question 16

Integrated ports are important for users in that

Answer 16

they provide lower system purchase prices, faster component performance, centralized control of components through the ROM BIOS and CMOS, and an interior that is less crowded with the add-on cards.

Question 17

Integrated ports are important for technicians in that

Answer 17

Fewer components need to be installed to make a system meet standard requirements and components can be enabled or disabled through the BIOS setup program.

Question 18

Components can become troublesome

Answer 18

because the systems must be repaired or upgraded

Question 19

Modern Motherboards include two or more memory slots

Answer 19

At least one memory slot must contain a memory module or the system cannot function

Question 20

SDRAM

Answer 20

uses three-section memory slots designed for 168 pin memory modules. Older systems

Question 21

DDR SDRAM

Answer 21

uses a two-section memory slot designed for 184-pin modules.

Question 22

DDR2 SDRAM

Answer 22

uses two-section memory slots designed for 240-pin modules.

Question 23

Locking Levers

Answer 23

secure memory in place. When the memory is properly installed, the levers automatically swivel into place.

Question 24

PCI

Answer 24

Peripheral component interconnect can be used for many types of add-ons including network, video, audio, I/O storage host adapters for SCSI, PATA, and SATA drives. 32-bit slot, 33 MHz frequency.

Question 25

AGP

Answer 25

is an accelerated graphics port, which introduced high-speed video 3D display,

Question 26

1/2x cards

Answer 26

3.3V

Question 27

4x

Answer 27

1.5 V

Question 28

8x cards

Answer 28

.8-1.5 V

Question 29

PCI cards

Answer 29

relay information serially over one or more lanes

Question 30

A lane

Answer 30

is a group of signal paths that can collectively transmit and receive data simultaneously.

Question 31

Full-duplex

Answer 31

1x PCI slot and cards are considered to be one-lane

Question 32

PCI express x1

Answer 32

V2.0 cards have a transfer rate of 500 MBps, this number increases with more lanes.
