Chapter 4 Motherboards and I/O Buses Flashcards
Information and data travels along this line or road which is narrow or wide.
Data bus line
Generates voltage to the components connected in the motherboard or the power source
Power bus line
Regulates the data trafficking of information flow or the stoplights in a city
Control bus line
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
Address bus line
System Bus
consists of lines for data to travel from one component to the next.
Motherboard
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.
Chipset
North and South Bridges of the motherboard
MCH
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.
RAM
Random Access Memory which is the virtual memory data bank stored during the clients session only.
ICH
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).
ATX
A rear port cluster for I/O ports
Expansion slots that run parallel to the short side of motherboard
Left side case opening
BTX
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
NLX
New low profile extended motherboards which feature a Riser card and daughter-boards which include one or more PCI expansion slots.
Daughterboard
circuit board that plugs into another board to provide extra functionality.
The most recent motherboards include which integrated ports>?
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
Integrated ports are important for users in that
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.
Integrated ports are important for technicians in that
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.
Components can become troublesome
because the systems must be repaired or upgraded
Modern Motherboards include two or more memory slots
At least one memory slot must contain a memory module or the system cannot function
SDRAM
uses three-section memory slots designed for 168 pin memory modules. Older systems
DDR SDRAM
uses a two-section memory slot designed for 184-pin modules.
DDR2 SDRAM
uses two-section memory slots designed for 240-pin modules.
Locking Levers
secure memory in place. When the memory is properly installed, the levers automatically swivel into place.
PCI
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.
