Section 3 - Motherboard Flashcards
Motherboard
Printed circuit board that contains computer components and provides connectors
What is input
Process of accepting data in a form that the computer can use
What is output
Process of displaying the processed data or information
What is processing
Action performed by the CPU when receiving information
Which components are in charge of processing
GPU or CPU
What is storage
Process of saving or retaining digital data, temporarily or permanently
What is temporary storage also known as and why
Non-persistant because the data will be lose after the pc is turned off
What is permanent storage also known as and why
Persistant because the data will be kept after the PC is turned off

MHz, GHz
In terms of speed, describe non-volatile storage
Speed decreases rapidly, MHz
In terms of speed, describe volatile storage
Speed is fast, GHz
What does form factor describe
Its shape, layout and type of case and power supply that will be used by system
form factors for motherboards
ATX, Mini-ATX, Micro-ATX
Explain ATX
Advanced Technology eXtended, Full-size motherboard, measures 12’’ x 9.6’’ in size
Explain Mini-ATX
Smaller than ATX with same features 11.2’’ x 8.2’’ - not very common
Explain Micro-ATX
9.6’’ x 9.6’’ - 4 expansion card slots
Explain ITX
Designed as a replacement for the ATX but never produced
Mini-ITX
Measures 6.7’’ x 6.7’’ with 1 expansion slot - Small cases, very common in small form factor PCs
3 other form factors of ITX
Nano-ITX, Pico-ITX, Mobile-ITX
Explain the x86 architecture (aka IA-32)
Developed by intel with an 8-bit,16-bit and up to 32-bit instruction set
Explain x64
Supports 64-bit instruction set
Explain the x86 limitation in terms of ram
allows for a max of 4GB of RAM
Explain 32 and 64 bit systems in terms of the programs they can run
64-bit can run 32 & 64 bit programs however 32-bit systems can only run 32-bit programs
What is Advanced RISC Machine (ARM) used for
Used for low-power devices (tablets and cell phones)
Advantages of ARM/RISC systems
Less power consumption and produces less heat
Explain RISC/ARM in terms of completing tasks
They use code to perform tasks
What is a Zero Insertion Force (ZIF) Mechanism
Involves inserting the CPU without pressing down and applying any pressure
Explain LGA (Land Grid Array by Intel)
Form factor socket that positions all the pins on the motherboard to connect into the holes of the CPU
Explain PGA (Pin Grid Array by AMD)
Form factor where the processor has the pins and socket has the holes
Explain the deal with motherboard sockets
A single socket arch on desktop motherboard can only support one physical processor
What does multi socket mean in terms of motherboards
Multiple CPUs or processors can be installed on the motherboard
What’s the difference when talking about processors on Desktops and Mobiles
A mobile tends to have its processor soldered in
Explain Simultaneous Multithreading(SMT)/Hyper-Threading
Single stream of instructions sent by the application rather than multiple, increasing overall efficiency
What are 2 features that CPUs have for accelerated processing
SMT(Simultaneous Multi-Threading), SMP (Symmetric Multi-Processing)
Explain Symmetric Multiprocessing (SMP)
Traditional workstation and servers have multiple processors
What is a multi-core processors
Single CPU with multiple processors inside
Explain Hexa-Core processor
Six CPUs inside a single chip
What are Intel’s and AMD’s names for Virtualisation?
Intel: VT & AMD: AMD-V
What do VT & AMD-V allow for
Processor extensions to support virtualisation
What does virtualisation allow for
the capacity to run multiple systems on a single physical host
What’s the second level of virtualisation used by AMD and INTEL
Intel: Extended page table (EPT) & AMD: Rapid virtualisation indexing (RVI)
What are the steps involved in installing a new motherboard
1)Review the specs of the motherboard, 2)Position the motherboard so its in line with the port cluster on the back of the case, 3)Insert the standoffs to match the hole location for the motherboard 4) Install the processor and memory modules before installing the motherboard 5) Verify the standoffs are properly aligned prior to installing the motherboard 6) Secure the standoffs using the correct screw type 7) Install the PSU, Disk drive, add-on cards and other components
What are the 2 main types of express card ports
PCIe (PCI Express) & Mini PCIe (Mini PCI Express)
PCI
32-bit expansion card
Max MHz of a PCI 32-bit card
33 MHz / 133 MBps
PCI-X 64-bit Max MHZ
133 MHz
PCI-X 2.0 Max MHz
266 up to 533 MHz
What was a problem with PCI-X
As it was backwards compatible, this meant that it would actually need to drop its MHz if it was matched with a PCI card with a speed of 33MHz to support the older bys
Accelerated Graphics Port (AGP)
used for video graphics cards
AGP flavours
1x, 2x, 4x, 8x
What did PCI Express replace
PCI, PCI-X, AGP
PCIe Flavours
x1, x4, x8, x16
What is PCIe x1 used for
modems, network cards, wireless cards, input/output devices, audio cards
What is PCIe x16 used for
Graphics cards
What does a Peripheral Component Interconnect Express (PCIe) do
Connects to the bus to get data to and from the motherboard for external devices
How many watts of power are provided by PCIe slots
25 watts
How many watts of power can be supplied by a x16 PCIe slot
75 watts
In terms of x, which PCIe’s are most common
x1 and x16
What is up-plugging
Putting smaller card in a larger slot e.g. network card into an x16 PCIe slot
What is down-plugging
