The central component of the computer and provides communications and power
distribution; it also provides the connection points for the processor, system memory,
storage drives, peripherals, expansion, power, etc. There are built-in components and
expansion slots/ports for additional functionality. - ANSWER>>motherboard
One of several form factors used for Personal Computers (PCs); it measures 9.6x12
inches. - ANSWER>>ATX
(AKA microATX) One of several form factors used for PCs, measuring 9.6x9.6-inch. It
supports a maximum of four (4) expansion slots and can be mounted into all ATX Tower
cases. - ANSWER>>mATX
Mini-ITX is one form factor for PCs; it measures 6.7x6.7 inches. Mini-ITX is the most
common motherboard in Mini Towers, Small Form Factors (SFFs), and Slim Profile PCs. -
ANSWER>>Mini-ITX
A bus. A bus used to connect peripherals or internal components to the motherboard
through expansion slots. It's being replaced by PCIe and is nearly in legacy status.
Peripheral Component Interconnect - ANSWER>>PCI
Upgrade from the PCI bus; much faster and adds the ability to use lanes. -
ANSWER>>PCIe
Component on the motherboard that does all of the primary processing of data. -
ANSWER>>CPU
Multiple separate processing cores on a single die whereas a dual-core processor is
two independent processing units. - ANSWER>>multicore
,When a program is executed, it is called a process. In that process, there are threads
that are units of execution within a process. - ANSWER>>multithreading
The CPU uses multiple hardware caches for data or instructions; generally, there are
three physical cache locations, though occasionally, there are four. -
ANSWER>>cache (L1, L2, L3)
This bridge has direct access to the CPU via the front-side bus, the fastest and closest
bus to the CPU. Its functions have mostly migrated from a separate chip on the
motherboard to being embedded within the CPU. - ANSWER>>northbridge
This bridge is part of a two-chip configuration that forms the motherboard's core logic
chipset architecture. - ANSWER>>southbridge
Means a number may have a maximum of 32 binary digits. A BInary digiT (bit) is one of
two possible digits, 0-1, and may represent, respectively, off/on or False/True. -
ANSWER>>32-bit
Means a number may have a maximum of 64 binary digits. A BInary digiT (bit) is one of
two possible digits, 0-1, and may represent, respectively, off/on or False/True. -
ANSWER>>64-bit
Also called system firmware, this is the program that begins the process of starting the
computer. - ANSWER>>BIOS
Provides same functionality as BIOS, but it is 32-bit; offers GUI and mouse-driven user
interface, and is 64-bit. - ANSWER>>UEFI
Basic or low-level software designed strictly for managing and controlling hardware
components.
, A chip embedded on the motherboard or CPU that adds security functions to the
computer at a hardware level. (Trusted Platform Module) - ANSWER>>TPM
This requires UEFI drivers, bootloaders, kernels and kernel modules be digitally signed
prior to allowing them into the operating system (OS) boot process. -
ANSWER>>Secure Boot
This is more commonly known as an expansion card, is a circuit board connected to a
motherboard via an expansion slot. - ANSWER>>adapter/expansion card
This is a volatile form of memory. - ANSWER>>RAM
This doubles the data rate by moving two data transfers per clock cycle. (Double Data
Rate) - ANSWER>>DDR
The second version of DDR SDRAM. - ANSWER>>DDR2
The third version of DDR SDRAM. - ANSWER>>DDR3
Fourth generation of DDR SDRAM. - ANSWER>>DDR4
A single bus that integrates the address bus, data bus and control bus connecting all
the major parts of the system. Most modern motherboards, that is starting from the 90s
use this one system-wide bus configuration very seldom. - ANSWER>>system bus
Predecessor of DDR(DDR SDRAM). - ANSWER>>SDRAM
This is non-volatile memory; data is imprinted on the memory device/media during
manufacturing and cannot be electrically altered. - ANSWER>>ROM (Read-Only
Memory)
