Prelims - Motherboard Flashcards
is a printed circuit board that is the foundation of a computer and allows the CPU, RAM and all other computer hardware components to function and communicate with each other
Motherboard
these connectors are usually used by CPU fans with higher power consumption
4-pin connectors
This device senses the CPU voltage requirements (usually via sense pins on the processor) and calibrates itself to provide the proper voltage to run the CPU
12v 4 pin CPU power connector
originally the motherboard was powered by
20-pin connector
is where the connectors of hard disk drive, activity lights, case speaker, reset, button, power on/off button, computer power on light, and key lock are connected to make them function smoothly
Front panel connectors
Types of system panel cables
HDD LED
POWER LED
POWER SW
RESET SW
The led activity light for the hard disk drive. This is the LED that flashes as information is being written and read from the hard drive.
HDD LED (IDE LED)
The LED power light which indicates when the computer is on, off, or in standby
POWER LED (PLED)
Controls the power button that allows you to turn on and off the computer
POWER SW (PWRSW)
Handles the reset button to restart the computer
RESET SW
is a chip located on all motherboards that contain instructions and setup for how your system should boot and how to operate
Basic Input/Output Sytem (BIOS)
To keep the clock chip running when power is off
CMOS BATTERY
is a conductor wire such as copper in a cylindrical form around an iron core that creates an inductor or electromagnet to stop magnetic energy
Inductor (electromagnetic coil)
is a chip inside a computer that connects the CPU to other primary components in the system
Northbridge
handles all of a computer’s I/O functions such as USB, audio, serial, the system BIOS, the ISA bus, the interrupt controller and IDE channels
Southbridge
is a class of I/O controller integrated circuits that began to be used on personal computer motherboards in the late 1980s
combines interfaces for a variety of low-bandwith devices
SUPER I/O controller
a set of electronic circuits on one small plate of semiconductor material, normally silicon
Integrated circuit (IC)
is a short length of conductor used to close a break in, or bypass part of an electrical circuit.
Jumpers
is a cheaper version of the leadless chipp carrier socket
Plastic Leadless Chipp Carrier (PLCC)
is used to store energy in an electric field
Capasitor
is a group of pins, typically on a computer motherboard or expansion card, to which an internal USB cable can be attached to provide extra USB ports
USB header
is a drive controller on your motherboard that supports both hard drives and CD-ROM, and DVD-ROM devices
Integrated Drive Electronics (or PATA) slot
is what allows computer memory to be inserted in the computer
Memory Slot
provides a medium to expand the capabilities of the PC by adding modems cards, audio card, ethernet cards
PCI SLOT
is one of the types of video cards available. are automatically detected as in-built video cards. they provide better resolution than onboard/integrated video
AGP slot
it was designed by intel to interface with chipsets and provide analog functionality, such as sound cards and modems on an expansion card
AMR SLOT (audio/modem riser)
it accepts plug-in boards that controls the sound, video display and other peripherals.
Industry standard architecture (ISA slot)
it was the traditional connector for joystick input devices
GAME PORT
is the replacement for lower bandwidth devices
PCI express x1
is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system
Central Processing Unit (CPU)
is a mechanical component that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB)
CPU socket
is a passive heat exchanger component that cools a devices by dissapating heat into the surrounding air. used to cool the CPU or graphic processors
heat sink
is a type of interface found on computers for connecting peripherals
Parallel port
is a 6-pin Mini-DIN connector used for connecting some keyboards and mice to a PC compatible computer system
PS/2 connector
it is a serial communication physical interface through which information transfers in our out one bit at a time
SERIAL PORT
is a port connection that allows a computer to connect to a network using wired connection
LAN PORT
is a device system designed for the accessories of the computer system, it allows you to hotswap any devices that is designed for the port
Universal Serial Bus (USB)
is a three-row 15-pin DE-15 connector. is found on many video cards, computer monitors, and high definition television sets
VGA PORT
